General Labratry Rules and Plicies 6.1. Apprpriate PPE must be wrn at all times. Minimum PPE is clse-ted shes and lng pants r a lab cat whenever hazardus materials are in use. Eye prtectin may als be required; see paragraph and Appendix L fr eye prtectin plicies Eating r drinking is nt allwed in any research r classrm lab at any time, nr shuld any fd r drink be brught int the labs Gd husekeeping practices shall be upheld in all labratries, and all passageways, exits, utility cntrls and emergency equipment must be accessible and unblcked at all times. 7. Hazard Identificatin and Cmmunicatin 7.1. Risk Assessments. Many chemicals can cause immediate health prblems as well as lng-term health effects. They can als pse inherent physical dangers, such as fire, explsin and high- 8

9 pressure hazards. The hazards will determine hw these materials shuld be stred and handled and what special equipment and prcedures are needed t use them safely. UW-Stut is cmmitted t minimizing expsure t these hazards and takes a risk-based apprach. Labratry supervisrs are respnsible fr reviewing all peratins invlving use f hazardus chemicals, assessing the risk and determining prper cntrls. Mre infrmatin n perfrming a risk assessment is fund in Appendix B. The CHO can als prvide guidance Expsure Limits. OSHA has the regulatry authrity t set specific expsure limits fr air cntaminants, called permissible expsure limits (PELs). They are listed in 29 CFR Table Z-1. The State f Wiscnsin has adpted the July 1, 1992 editin f 29 CFR , published in Safety and Prfessinal Services (SPS) standard SPS Many PELs are 8-hur time-weighted averages, and there are als shrt term expsure limits (STELs) that are typically 15-minute limits, and ceiling limits that shuld never be exceeded. Fr substances that d nt have an OSHA PEL, SPS 332 states that it will accept the recmmendatins f the American Cnference f Gvernmental Industrial Hygienists Threshld Limit Values (TLVs). Mst labratry wrkers perfrm nn-rutine peratins ver a shrt time span, in which case STELs are ften mre apprpriate than 8-hur PELs r TLVs. See Appendix O fr mre infrmatin n expsure limits Labels. Cntainer labels prvide valuable health and safety infrmatin fr hazardus substances. The CHO has the verall respnsibility fr ensuring that all chemical cntainers are labeled in accrdance with this sectin. Labratry supervisrs are respnsible fr ensuring that all chemical cntainers in their wrk area are labeled in accrdance with this sectin Labels n shipped cntainers. Chemical manufacturers, imprters and distributrs are respnsible fr ensuring that their prducts are delivered with the prper labeling. At a minimum, prper labeling means a label that meets requirements as defined in OSHA s Hazard Cmmunicatin standard, 29 CFR (f)(1). OSHA adpted the Glbally Harmnized System f Chemical Classificatin and Labeling f Chemicals (GHS) as part f an updated Hazard Cmmunicatin standard. As f June 1, 2015, all labels must meet the requirements in the new Hazard Cmmunicatin standard. During the transitin perid labels may cmply with the new standard, the ld standard r bth. UW-Stut shall nt accept delivery f a prduct that des nt meet minimum labeling requirements Cntainer labels under the new standard must include pictgrams, a signal wrd, hazard and precautinary statements, the prduct identifier and supplier identificatin Cntainer labels under the ld standard must include the identity f hazardus chemical(s), apprpriate hazard warning, and the name and address f the chemical manufacturer, imprter r ther respnsible party Labels n secndary cntainers. Secndary cntainers are created when a chemical is transferred frm a manufacturer s labeled cntainer int a mre prtable cntainer The secndary cntainer des nt need t be labeled if it will be used immediately (during ne wrk shift) by the persn wh perfrmed the transfer. 9

10 If the secndary cntainer will be used fr strage f a chemical and/r by a persn wh did nt perfrm the transfer frm the manufacturer s cntainer it must be labeled with a prduct identifier and wrds, pictures, symbls r cmbinatin, which prvide at least general infrmatin regarding the hazards f the chemical and which prvides specific infrmatin regarding the physical and health hazards f the chemical The labels shall be maintained in a legible cnditin. Manufacturer s labels shall nt be defaced r remved unless the cntainer is immediately labeled with the required infrmatin. Any cntainer withut a label r with an illegible label shall be reprted t the labratry supervisr immediately See Appendix C fr additinal infrmatin n UW-Stut s label plicy Hazardus waste cntainers shall have the cntents, date f generatin and generatr s name (r department) listed n the label in additin t the wrds Hazardus Waste. Additinal infrmatin that will aid in prper waste dispsal shuld als be included n the label if knwn Safety Data Sheets (SDSs). SDSs are prepared by manufacturers and summarize the physical and chemical characteristics, health and safety infrmatin, handling and emergency respnse recmmendatins fr their prducts. SDSs shuld be reviewed befre beginning wrk with a chemical The CHO is respnsible fr maintaining a master SDS file fr all chemicals used and stred in UW-Stut labratries cvered by the Labratry Standard. As f summer 2011 the master SDS file shall be stred in CISPr. SDSs must be readily available t emplyees and students during all wrk shifts The CHO will crdinate peridic audits f SDSs t ensure they are up t date. Any missing r utdated SDSs can be btained by cntacting the manufacturer (see Appendix D) r the CHO The SDS shall be kept n file fr thirty years after the chemical was last n campus. Outdated r discntinued paper SDSs shall be sent t Safety and Risk Management fr archiving. SDSs updated in CISPr are archived in the inventry system See Appendix D fr additinal infrmatin abut SDSs and links t nline surces Signage. The fllwing signage shall be psted in each labratry: A summary f hazards. The CHO shall be respnsible fr creating, updating and psting these signs utside the drs t each lab Emergency prcedures and telephne numbers Lcatin signs fr safety shwers, eyewash statins, ther safety and first aid equipment if nt readily visible frm all parts f the labratry. 10

11 Signage n refrigeratrs where fd strage is nt allwed, and n refrigeratrs/freezers nt designed fr strage f flammable materials Labeling n fd stuff that is nt intended fr human cnsumptin Cautin signs indicating special r unusual hazards shall be psted as necessary and deemed apprpriate by the labratry supervisr, CHO r Safety and Risk Management. Appendix H discusses special signage fr PHSs. 8. Cntrl Measures t Reduce Expsure t Hazardus Chemicals 8.1. Cntrlling expsures t labratry hazards is the fundamental methd f prtecting labratry users. A hierarchy f cntrls shall be used as a means f determining hw t implement feasible and effective cntrls. The cntrl methds at the tp f the hierarchy are mre effective and prtective than thse at the bttm: 8.2. Eliminatin and substitutin are the mst prtective frms f cntrl because they remve the hazard altgether, either by eliminating the hazardus material r prcess altgether r by substituting it with a less- r nn-hazardus material r prcess. It is much easier and less expensive t implement eliminatin r substitutin in the planning phase than after a prcess is in place; therefre it is imprtant t plan carefully when designing new research r instructin and knw the hazards f the materials and prcesses invlved Engineering Cntrls. Engineering cntrls islate the hazard r remve cntaminants thrugh varius ventilatin methds Dilutin Ventilatin Adequate ventilatin is essential fr maintaining safe levels f expsure. All labratries lcated in Jarvis Science Wing and Additin have dilutin ventilatin prviding 100% exhaust. It is the respnsibility f the labratry supervisr t discntinue labratry peratins if ventilatin is judged t be inadequate fr any reasn Labratries are negative pressure t hallways t cntain chemical vaprs and drs within the labs and facilitate efficient remval by the ventilatin system. 11

12 Chemical Fume Hds The determinatin that a hd is necessary fr a prcess shall be based n a risk assessment, which shuld include a review f the physical characteristics, quantity, vlatility and txicity f the materials t be used, the number and sphisticatin f manipulatins, etc. The skill and expertise f the individual perfrming the wrk shuld als be cnsidered In general, fume hds shuld be used with all particularly hazardus substances and any ther chemicals that present an inhalatin hazard Lab wrkers must understand hw t prperly use chemical fume hds. Labratry supervisrs are respnsible fr ensuring that their wrkers are prperly trained and that training is dcumented As much as pssible, fume hds shall nt be used as chemical strage areas. String materials in fume hds reduces their efficiency, clutters the wrk space and culd lead t inadvertent mixing f incmpatible chemicals. Lng-term chemical prcedures and experiments are allwed in fume hds as required and are nt cnsidered strage. There are vented cabinets available in Jarvis Science Wing Additin fr maldrus and highly vlatile chemical strage Fume hds lcated in Heritage Hall and Jarvis Science Wing and Additin d nt perate cntinuusly. They must be manually turned n. While n, air flw velcities are n a cntinuus mnitr alarm system (Jarvis hds nly) Fume hds shall be checked annually by the CHO using a calibrated thermal anemmeter t cnfirm minimum rates. Deficiencies will be reprted t UW-Stut Physical Plant fr repair. Ventilatin fr labratry fume hds shall fllw the Wiscnsin Public Emplyee Safety and Health standard, SPS (6), which requires a minimum average 100 feet per minute face velcity at full pen sash r sash stp psitin. When determining the minimum flw rate thrugh the fume hd, the sash stp psitin may nt be lwer than 18 inches abve the wrk surface. Inspectin results shall be psted n each fume hd. Fume hds with inadequate face velcities r ther serius prblems shall be prminently marked and taken ut f service until repaired See Appendix E fr additinal infrmatin n fume hds including user guidelines Bisafety cabinets are lcated in several Jarvis Science Additin labratries. The CHO is respnsible fr crdinating testing as required, which must be dne annually. Bisafety cabinets are nt chemical fume hds and shall nt be used fr chemical manipulatins Air quality mnitring fr hazardus air cntaminants will be cnducted as deemed necessary in cnsultatin with the CHO and Safety and Risk Management. The CHO shall crdinate and/r cnduct these studies Administrative Cntrls. Administrative cntrls fr hazardus chemical usage cnsist f plicies and prcedures develped t imprve the safety f labratry peratins. Since they require 12

13 wrkers t fllw apprpriate prcedures they are generally nt as reliable as engineering cntrls Standard Operating Prcedures (SOPs) Sme general SOPs fr safe handling f hazardus materials in labs can be fund in Appendix F Labratry supervisrs are respnsible fr maintaining safe SOPs in labratries under their supervisin Particularly Hazardus Substances (PHSs) Prvisins fr additinal emplyee prtectin fr wrk with PHSs as defined by the Labratry Standard have been established. PHSs include carcingens, reprductive txins, and substances with a high degree f acute txicity. Sme highly reactive substances (e.g., pyrphrics) may als be cnsidered PHSs Individuals must receive pre-apprval befre beginning wrk with a PHS. The preapprval prcess starts with cmpletin and submissin f the PHS apprval frm. The CHO and the respnsible department chair are respnsible fr reviewing and apprving use f PHSs. Requirements fr additinal emplyee prtectin fr wrk with PHS will include: Establishment f a designated area Use f engineering cntrls and PPE Prcedures fr safe remval f cntaminated waste Decntaminatin prcedures Respnsibility fr identifying PHSs and cmplying with the established apprval prcess ultimately rests with faculty, PI r lab instructr. Training n identifying PHSs and the apprval prcess will be included in required lab safety training. See Appendix G fr additinal infrmatin n UW-Stut plicy fr wrk with PHSs and fr a cpy f the PHS apprval frm Prir Apprval. The labratry supervisr, in cnsultatin with the CHO, is respnsible fr identifying lab peratins that may require prir apprval In general, the fllwing will require prir apprval: When it is likely that PELs culd be exceeded r that ther harm is likely Prcedures using PHSs, radiactive r bi-hazardus substances f risk grup 2 r higher. Fr bi-hazardus substances, refer t the UW-Stut Bisafety Manual n the Labratry Safety website (see paragraph 1.4 fr instructins fr lgging in). 13

14 First-time use f a particular piece f labratry equipment that has a substantial chemical, physical r bilgical risk assciated with its use Use f vlatile substance in cld rms, warm rms r ther rms with limited ventilatin When wrking alne in labratries/buildings with significant hazardus substances and peratins Prcedures invlving unattended peratin The PHS apprval frm shall be cmpleted and submitted t the CHO fr review fr all peratins requiring prir apprval Husekeeping. All labratries shall be maintained at a satisfactry level f rderliness and cleanliness Chemicals and equipment that are nt in use and may pse an imminent danger must be stred r dispsed f Walkways and exit rutes must be free f bstructins Access t safety equipment (e.g., safety shwers, eyewashes, fire extinguishers) and electrical panels must be free f bstructins Benches and active wrk spaces shuld be rganized, leaving adequate wrkspace fr safe wrk practices N chemicals shall be stred mre than six feet abve the flr r n the flr Chemical spills must be cleaned up prmptly Labratry supervisrs are directly respnsible fr maintaining acceptable husekeeping in their wrk area. The CHO will include an audit f husekeeping in peridic lab audit Emergency Prcedures The fllwing are fund in Appendix I: UW-Stut Emergency Guide: Includes emergency guidelines identifying varius types f emergency situatins, suggested actins and wh t call UW-Stut Labratry Medical Emergency Actin Plan: Prvides infrmatin fr faculty and staff n respnsibilities fr respnding t medical emergencies in the labratry UW-Stut Labratry First Aid Guide: Guidance n respnding t cmmn first aid emergencies encuntered in labratries. These are intended as limited invlvement measures t take until emergency persnnel arrive n the scene. 14

15 UW-Stut Emergency Guide will be psted near the exit drs f labratries. The CHO is respnsible fr crdinating psting f emergency prcedures UW-Stut emplyees cvered by the Labratry Standard will receive training n emergency prcedures. Labratry supervisrs are respnsible fr educating students cncerning emergency prcedures as utlined in the UW-Stut Emergency Guide Labratry supervisrs are als respnsible fr infrming students and visitrs f an emergency and fr initiating emergency prcedures when needed Incident Reprts. Any event that requires a first aid respnse, activatin f eye wash r bdy shwer, activatin f fire alarm, use f fire extinguisher and/r spill respnse requiring utside assistance must be reprted using the UW-Stut incident frm fund in Appendix I. The cmpleted frm shall be submitted t the CHO with a cpy sent t Safety and Risk Management. Any incident that results in illness r injury t an emplyee must be reprted t Human Resurces thrugh the emplyee s supervisr using the wrkers cmpensatin frm ( Chemical Spills The cleanup f a spill must nly be perfrmed by knwledgeable and experienced persnnel. Spill kits with instructins, absrbents, reactants and PPE are available fr cleanup f minr spills. A minr spill is ne that the labratry staff is capable f handling safely withut the assistance f safety and emergency persnnel. See Appendix J fr mre infrmatin n spill cleanup, and Appendix N fr the lcatin f spill kits All ther chemical spills are cnsidered a majr spill. In the event f a majr spill, remve all persns frm the area, clse drs t the affected area r therwise limit access t the spill and call 911. Be prepared t prvide the dispatcher with the exact lcatin f the spill, chemical name, amunt spilled and the actins taken by labratry staff t islate the spill Labratry Audits. The CHO shall cnduct annual audits f all UW-Stut labratries cvered by the Labratry Standard. Inspectins shall be cnducted while the labratry is in use s that the perating prcedures will be verified as being fllwed by all persnnel and students. Inspectin results and checklists used shall be cmmunicated t the labratry supervisr f the wrk area inspected after cmpletin f the inspectin. Inspectin results shall als be cpied t department chair and Safety and Risk Management Persnal Prtective Equipment (PPE). PPE is the hazard cntrl mechanism f last resrt. Whenever pssible, the hazard shuld be mitigated by eliminatin r substitutin, r minimized using engineering r administrative cntrls. If it is nt pssible t cntrl the hazard in any ther way, PPE must be used At a minimum, lng pants r a lab cat and clse-ted shes must be wrn in labratries when hazardus materials are in use. 15

16 When wrking with hazardus chemicals, rutine PPE may include a labratry cat (r equivalent) and prtective eye wear. Special prcedures may require special prtective equipment n a case by case basis. Fr example, glves made f chemically cmpatible material shuld be wrn with strng crrsives r with PHSs as applicable. If such prcedures are rutinely encuntered, they shuld be included in the SOPs fr the lab The CHO shall assess the labratries t determine if hazards that necessitate the use f PPE are present r are likely t be present. A written hazard assessment must be cmpleted and n file fr each labratry PPE shuld be inspected befre dnning, and defective r damaged PPE shall nt be used When selecting PPE it is critical that it be cmpatible with and rated prperly fr the specific chemical. There may be multiple surces that need t be investigated t find the prper PPE fr the given applicatin. All PPE that has limitatin and ratings disclaimers must be reviewed.

Chemical Waste Management UW-Stut is cmmitted t respnsible management f its hazardus waste and cmpliance with all applicable U.S. Envirnmental Prtectin Agency (EPA) and Wiscnsin Department f Natural Resurces (DNR) rules. A sund waste management prgram fllws the waste 18

19 management hierarchy. Reducing waste prductin at the surce, recvery, reuse, recycling and n-site treatment are waste minimizatin practices that shuld be cnsidered befre dispsal. See Appendix K fr the UW-Stut Hazardus Waste Prgram The CHO shall crdinate hazardus waste dispsal fr labratries cvered by the Labratry Standard. Safety and Risk Management is available t assist and cnsult with departments in hazardus waste management and arranges all hazardus waste dispsals thrugh the UW- Stut hazardus waste prgram Hazardus waste training is required fr emplyees invlved in management r generatin f hazardus wastes. 11. Cntrlled Substances (Drug Enfrcement Agency) A cntrlled substance is a drug that is regulated by state and federal laws that aim t cntrl the danger f addictin, abuse, harm and illegal trafficking. They may be illegal fr sale r use, but can be permitted fr legitimate use in research When planning fr research that invlves drugs, the PI shall identify whether the drug is a cntrlled substance and act accrdingly. The U.S. Drug Enfrcement Agency (DEA) publishes schedules f cntrlled substances: The use f cntrlled substances fr research requires btaining bth state (Wiscnsin Cntrlled Substances Bard Special Use Authrizatin) and federal (DEA) registratin. The state registratin must be btained first. Penalties fr using cntrlled substances withut prper registratin can be severe. The regulatins strictly limit wh can handle r administer the drugs and impses physical security and inventry requirements The permitting prcess is between and individual researcher and the state and DEA. Registrants cannt share cntrlled substances with nn-registered users wh are nt under their supervisin Pssessin f expired substances can bring additinal scrutiny frm the U.S. Department f Agriculture since administratin f expired substances is nt allwed Dispsal is strictly regulated by the DEA Neither the CHO nr Safety and Risk Management play a rle in the permitting prcess, althugh the CHO can prvide limited guidance The UW-Madisn Research Animal Resurces Center has very gd guidance n the use f cntrlled substances: Training UW-Stut will prvide emplyees, including faculty and staff wrking in labratries cvered by the Labratry Standard, with infrmatin and training t ensure that they are apprised f the hazards, including chemicals, present in their wrk area. 19

The CHO will prvide assistance with student training upn request and can enrll students in the D2L training. Labratry supervisrs shall retain dcumentatin f student training. 13. Medical Surveillance and Cnsultatin The Labratry Standard mandates that emplyers prvide medical attentin, examinatins and fllw-up examinatins (at the physician s discretin) under the fllwing circumstances: 20

21 Whenever an emplyee develps signs and/r symptms assciated with a hazardus chemical t which they may have been expsed Whenever expsure mnitring reveals an expsure level abut the OSHA actin level r expsure abve the PEL fr OSHA regulated substances Whenever an event takes place in the wrk area such as a spill, leak, explsin, r ther ccurrence that results in the likelihd f a hazardus expsure. Such an ccurrence requires an pprtunity fr medical cnsultatin fr the purpse f determining the need fr a medical examinatin In the event f a pssible expsure, the affected individual (r ther labratry staff present) must be prepared t prvide the examining physician the fllwing infrmatin: Identity f the hazardus chemical(s) t which the emplyee may have been expsed A descriptin f the cnditins under which the expsure ccurred including quantitative expsure data, if available A descriptin f the signs and symptms f expsure, if any, that the emplyee is experiencing A cpy f the relevant SDS r ther infrmatin The CHO shall request a written pinin frm the physician including: Recmmendatin fr future medical fllw-up Results f examinatin and assciated tests Any medical cnditin revealed that may place the emplyee at increased risk as a result f chemical expsure A statement that the emplyee has been infrmed by the physician f the results f the examinatin r cnsultatin and tld f any medical cnditins that may require additinal examinatin r treatment The material returned by the physician shall nt include specific findings and/r diagnses that are unrelated t ccupatinal expsure Safety and Risk Management has respnsibility t maintain a file cncerning any events and resultant medical examinatins r cnsultatins All medical examinatins and cnsultatins shall be perfrmed by r under the direct supervisin f a licensed physician and shall be prvided withut cst t the emplyee, withut lss f pay and at a reasnable time and place. The emplyee and their supervisr must cmplete a wrkers cmpensatin reprt fr any f the abve incidents. Students and nnemplyees must cmplete an incident reprt alng with their labratry supervisr. 14. Wrking Alne in the Labratries: The fllwing plicy has been adpted fr all persns using UW-Stut labratries cvered by the Labratry Standard. 21

22 14.1. N ne (including faculty/staff) may wrk alne if activities invlve use r manipulatin f hazardus materials r if hazardus cnditins exist (e.g., high pressure, high vltage, and vacuum systems). "Wrking alne" means wrking ut f sight r sund cmmunicatins with anther persn fr mre than five minutes. Overnight prcedures requiring high pressure, high vltage, r vacuum system are nly t be dne where there is n ther reasnable way f accmplishing this prcedure and expsure t any ptential hazard is minimal. Situatins where there is danger f explsin, implsin r expsure t UV, X-ray r high vltage require a ntice psted n dr if left unattended. Prir apprval must be given fr unattended peratins Undergraduate students in scheduled curses must be supervised at all times. Students may nt wrk ut f hurs fr any scheduled curse unless specific permissin is granted by the faculty persn supervising the lab and students will nt be ding any manipulatins using hazardus chemicals and hazardus cnditins d nt exist Student researchers (bth graduate and undergraduate students) may never wrk alne if wrking with hazardus chemicals r if hazardus cnditins exist. Ultimately it is the respnsibility f the PI t ensure safe supervisin f undergraduate and graduate researchers. 15. Labratry Visitatin All visitrs wh are passing thrugh r turing a labratry must be under the direct supervisin f a UW-Stut emplyee wh is trained and knwledgeable f the area's hazards Prir t allwing visitrs t tur r bserve in a lab, the supervising emplyee must cnduct a basic safety rientatin, including bth general safety infrmatin and any hazards particular t the lab in questin The visitrs must be infrmed abut prper clthing and ther prtective equipment prir t the visit s they can bring it with them, r it must be prvided t them.

24 Appendix B Assessing Risks in the Labratry The infrmatin in this appendix is summarized frm the Natinal Research Cuncil s Prudent Practices in the Labratry: Handling and Management f Chemical Hazards, updated versin (2011). A key element f planning an experiment is assessing the hazards and ptential risks assciated with the chemicals and labratry peratins t be used. This appendix prvides a practical guide t cnducting a risk assessment fr the trained labratry persnnel invlved in these activities. The primary respnsibility fr prper hazard evaluatins and risk assessments lies with the persn perfrming the experiment; respnsibility is als shared by the lab supervisr. Evaluatins and assessments may be perfrmed by trained labratry persnnel, but they shuld be checked and authrized by the supervisr. The supervisr is als respnsible fr ensuring that everyne invlved in an experiment and thse nearby understand the evaluatins and assessments. The Chemical Hygiene Officer (CHO) can be cnsulted fr guidance. There are seven steps invlved in hazard evaluatin and risk assessment: 1. Identify the chemicals t be used and circumstances f use. Identify the chemicals needed fr the prpsed experiment and determine the amunts that will be used. Is the experiment t be dne nce, r will the chemicals be handled repeatedly? Will the experiment be cnducted in an pen labratry, in an enclsed apparatus, r in a chemical fume hd? Is it pssible that new r unknwn substances will be generated in the experiment? Are any f the trained labratry persnnel invlved in the experiment pregnant r likely t becme pregnant? D they have any knwn sensitivities r allergies t specific chemicals? 2. Cnsult surces f infrmatin n hazards. Cnsult an up-t-date Safety Data Sheet (SDS), Labratry Chemical Safety Summary ( r ther references fr the hazards f the chemicals needed fr the prpsed experiment. Other references: Internatinal Chemical Safety Cards frm the Internatinal Prgramme n Chemical Safety: NIOSH Pcket Guide t Chemical Hazards: TLVs and BEIs frm the American Cnference f Gvernmental Industrial Hygienists. The CHO has a cpy. See Appendix O fr further infrmatin n expsure limits. Agency fr Txic Substances and Disease Registry: The University f Califrnia Center fr Labratry Safety. Lk under Resurces fr SOP templates that cntain specific chemical infrmatin and featured chemicals: 3. Evaluate the hazards. Chemicals can be divided int several different hazard classes, and many chemicals will belng t mre than ne class. The hazard class will determine hw these materials shuld be stred and handled and what special equipment and prcedures are needed t use them 24

25 safely. Therefre, it is essential that the hazards are defined and cntrlled prir t beginning an experiment. Mst chemicals have either physical r health hazards, r bth. Physical hazards: Flammable: in general, a liquid chemical is cnsidered flammable if it has a flash pint f less than 140 F. There are als flammable slids, gases and aersls. Pyrphric chemicals will ignite spntaneusly in air at a temperature f than 130 F r belw and must be very carefully handled. Oxidizers are nt flammable but initiate r prmte cmbustin in ther materials, thereby either causing fire themselves r thrugh the release f xygen r ther gases. Explsive: an explsive is a chemical that causes a sudden, almst instantaneus release f pressure, gas and heat when subjected t sudden shck, pressure r high temperature. Cmpressed gases are under great pressure in a cntainer that, if ruptured, can rapidly release pressure and becme a prjectile danger. Sme materials, such as perxide frmers, may nt have explsive tendencies themselves but may frm explsive substances ver time Reactive: reactive substances can release gases that will burn, explde r prduce high pressure that can cause injury. In sme instances they can release substances that are significantly mre txic than themselves. Unstable materials can vigrusly plymerize, decmpse, cndense r becme self-reactive under cnditins f shck, pressure r temperature. Water-reactive materials react with water t release a gas that is either flammable r presents a health hazard. Health hazards: Carcingen: a carcingen has the ptential t cause cancer. Substances may be categrized as knwn r suspected human carcingens. Txin: OSHA defines a chemical as being acutely txic depending n the effects ccurring fllwing ral r dermal administratin f a single dse f a substance, r multiple dses given within 24 hurs, r an inhalatin expsure f fur hurs. The criteria are defined in Sectin A.1 f this link: Use the surces f infrmatin in step 2 and the criteria in the link t classify the txin based n its LD 50. Fr substances that pse an inhalatin hazard, take nte f the permissible expsure limit, shrt-term expsure limit, threshld limit value and/r ther regulatry r recmmended expsure limits (see Appendix O). Crrsive: a crrsive chemical causes visible destructin f, r irreversible alteratins in, living tissue by chemical actin at the site f cntact. Irritant: an irritant is nt crrsive, but causes a reversible inflammatry effect n living tissue by chemical actin at the site f cntact. 25

26 Sensitizer: a sensitizer causes a substantial prprtin f expsed peple r animals t develp an allergic reactin in nrmal tissue after repeated expsure t the chemical. Chemicals can be skin r respiratry sensitizers. Target rgan txin: certain chemicals may cause damage t specific rgans. Categries include hepattxins (liver), nephrtxins (kidney), neurtxins (nervus system), hemtxins (bld/hematpietic system) and respiratry txins. Reprductive txins: reprductive txins cause adverse effects n sexual functin in adult males and females, as well as adverse effects n develpment f ffspring Other hazards: Nanmaterials: the increasing use f nanmaterials in research labs warrants cnsideratin f the hazards they may pse. As is the case with many new technlgies, the health effects f nanmaterials have nt been thrughly investigated. Cnsequently, the uncertainty surrunding the txicity f nanmaterials merits a cautius apprach. Nanmaterials include any materials r particles that have an external dimensin in the nanscale (~1-100 nanmeters). Nanmaterials can be categrized by the ptential risk f expsure they pse based n the physical state f the materials and the cnditins in which they are used. In general, the risk f expsure is lwest when the materials are bund in a slid matrix with little ptential t create airbrne dust r when in a nn-vlatile liquid suspensin. The risk f expsure increases when the nanmaterials are used as fine pwders r are suspended in vlatile slvents r gases. The parent cmpund shuld als be taken int cnsideratin when evaluating the ptential hazards (e.g., a highly txic cmpund such as cadmium shuld be anticipated t be at least as txic and pssibly mre txic when used as a nanmaterial). Bihazards: bilgical hazards are a cncern in labs in which micrrganisms, r material cntaminated with them, are handled. Anyne wh is likely t cme in cntact with bld r ther ptentially infectius material is cvered under OSHA s Bldbrne Pathgen Standard (29 CFR ). Cnsult the UW-Stut Bisafety Manual (n the Labratry Safety website) fr mre infrmatin n cntrlling bilgical hazards. Radiatin: radiatin hazards include thse frm inizing radiatin (alpha and beta particles, gamma and x-rays) and nn-inizing radiatin (UV, IR, lasers). Any experiments invlving expsure t radiatin must be crdinated with the CHO t ensure all federal and state regulatins are met. 4. Cnsider pssible rutes f expsure. Determine the ptential rutes f expsure fr each chemical: there may be mre than ne. Cmmn rutes are inhalatin, ingestin, skin cntact and absrptin, but injectin may als need t be cnsidered. Are the chemicals gases, r are they vlatile enugh t present a significant risk f expsure thrugh inhalatin? If liquid, can the substance be absrbed thrugh the skin? Is it pssible that dusts r aersls will be frmed in the experiment? Des the experiment invlve a significant risk f inadvertent ingestin r injectin f chemicals? The surces f infrmatin listed in step 2 can help. 5. Evaluate the hazards psed by the required equipment. Review prcedures fr crrect use f all equipment. Identify heat and ignitin surces and cnsider apprpriate placement frm them in 26

27 the labratry. Are any pieces f equipment ging t be under high r lw pressure (e.g., a vacuum line)? Is all glassware free f cracks and chips? 6. Select apprpriate prcedures t minimize expsure. Use the basic prudent practices fr handling chemicals, as discussed in this Chemical Hygiene Plan and ther references such as Prudent Practices in the Labratry ( fr the 1995 versin; the CHO has the updated 2011 versin). Use the hierarchy f cntrls cvered in Sectin 8 f this dcument t minimize the risk psed by the chemicals and equipment t be used in the experiment. Cnsult with the CHO fr assistance with this step. 7. Prepare fr cntingencies. Be aware f UW-Stut plicies and prcedures in the event f emergencies and accidents. Nte the signs and symptms f expsure t the chemicals t be used in the experiment. Sme questins t cnsider are: What are apprpriate measures t take in the event f fire, explsin, injury, spill r expsure t ptentially dangerus quantities f a chemical? What are the apprpriate first aid prcedures in the event f heat, cld r chemical burns? 27

28 Appendix C Labels On March 26, 2012 OSHA published the Hazard Cmmunicatin Final Rule in the Federal Register, in which it mdified the Hazard Cmmunicatin standard t cnfrm t GHS. The effective date f the final rule is 60 days after the date f publicatin. As f June 1, 2015, all labels will be required t meet the requirements in the new Hazard Cmmunicatin standard. During the transitin perid labels may cmply with the new standard, the ld standard, r bth. UW-Stut shall nt accept delivery f a prduct that des nt meet minimum labeling requirements. Under the new standard, labels n shipped cntainers must include: Prduct identifier used n the Safety Data Sheet (SDS). Name, address and telephne number f the chemical manufacturer, imprter r respnsible party. Signal wrd: a wrd used t indicate the relative severity f hazard and alert the reader t a ptential hazard. The signal wrd is either Danger fr mre severe hazards, r Warning fr less severe hazards. Hazard statement(s): a statement assigned t a hazard class and categry that describes the nature f the hazard(s) f a chemical, including, where apprpriate, the degree f hazard. Pictgram(s): a symbl with a specific brder and clr that is intended t cnvey visual infrmatin abut the hazards. Eight pictgrams are designated in the new Hazard Cmmunicatin standard, as shwn in Figure C-1. 28

30 Figure C-2: Sample GHS-Cmpliant Label Under the ld standard, labels n shipped cntainers must include: Identity f the hazardus substance. Apprpriate hazard warning. Name and address f the manufacturer. Labels n incming cntainers f hazardus chemicals shall remain n the cntainer and prtected. UW- Stut staff shall apprpriately re-label the riginal cntainer if the label becmes defaced, remved r therwise illegible. Labels n secndary cntainers. Secndary cntainers are created when a chemical is transferred frm a manufacturer s labeled cntainer int anther cntainer. This may happen if a prtin f the hazardus substance is transferred frm the riginal cntainer t a smaller cntainer fr use at the labratry bench, r t prepare a reagent fr use in the labratry (this culd be a dilutin r it culd invlve preparatin f a mixture). 30

31 If the secndary cntainer will be under the immediate cntrl f the persn wh perfrms the transfer it des nt require a label. If the secndary cntainer will be used fr strage f a chemical and/r by a persn wh did nt perfrm the transfer frm the manufacturer s cntainer it must be labeled in accrdance with either the new standards in paragraph 2 abve, r: Identity f the hazardus chemical(s), matching the SDS name. Apprpriate hazard warning(s). Hazard warning means any wrds, pictures, symbls, r cmbinatin theref appearing n a label r ther apprpriate frm f warning that cnvey the specific physical and health hazards, including any target rgan effects, f the chemical(s) in the cntainer. Use f the Natinal Fire Prtectin Assciatin (NFPA) r Hazardus Materials Identificatin System (HMIS) symbls may nt be sufficient t cnvey apprpriate warning abut the physical and health hazards, and in particular infrmatin abut target rgans. Therefre, the hazard warning may require a brief statement abut the physical and health hazard effects f the chemical (e.g. causes lung cancer ). Infrmatin prvided n the manufacturer s label and the SDS shuld be helpful in apprpriately labeling secndary cntainers. The Chemical Hygiene Officer will als prvide assistance in determining required label elements. Apprpriate secndary cntainer labeling is the primary respnsibility f the persn wh has direct cntrl f the cntainer. Labratry supervisrs are respnsible fr ensuring that all cntainers f hazardus substances in their wrk area are meet Hazard Cmmunicatin Standard labeling requirements. Other labeling systems are still allwed by OSHA, including the NFPA 704 diamnd and HMIS, as lng as they are cnsistent with the requirements f the Hazard Cmmunicatin Standard and emplyees have immediate access t specific hazard infrmatin. All drs t Jarvis Science Wing and Additin and Heritage Hall labs have a hazard sign that uses bth GHS pictgrams and the NFPA diamnd t give an verview f the chemical hazards cntained within that rm. Figure C-3 illustrates the NFPA system. 31
