All chemical laboratories within the schools are required to comply with this standard. It is recommended that the Plan be reviewed and updated annually. The current review was conducted on April 23, 2014. Actual use of this plan is limited to the Chisago Lakes Public School District. 1
Writ Haz CL Chem Hyg Chisago Lakes Area Schools, ISD #2144 Orig. 3/26/2001 13750 Lake Blvd. Revised 4/23/2014 Lindstrom, MN 55045 (651) 213-2000 Chemical Hygiene Management Plan Overview of Standard The Occupational Exposure to Hazardous Chemicals in Laboratories (29 CFR 1910.1450) became effective on May 1, 1990. This standard covers all laboratories engaged in the laboratory use of hazardous chemicals. However, the standard does not cover laboratory use of hazardous chemicals which present no potential for employee exposures (e.g. chemically impregnated test strips). If the chemical composition of a substance is produced exclusively for the laboratory's own use, the School District shall assume it to be hazardous. Definitions "Action Level" is the eight-hour time-weighted average concentration for a substance which, if exceeded, requires various activities such as medical surveillance and exposure monitoring be initiated. The Action Level is often times one-half the OSHA Permissible Exposure Limit for the substance. "Combustible Liquid" is a liquid having a flashpoint at or above 100 F (37.8 C), but below 200 F (93.3 C). It also includes any mixture having components with flashpoints above 200 F (93.3 C) and the volume makes up 99 percent or more of the total volume. "Flammable Gas" is any gas that, at ambient temperature and pressure, forms a flammable mixture with air at a concentration of 13 percent by volume or less or a gas that at ambient temperature and pressure forms a range of flammable mixtures with air wider than 12 percent by volume regardless of the lower limit. "Flammable Liquid" is any liquid with a flashpoint below 100 F (37.8 C) or a mixture having components with flashpoints of greater than 100 F (37.8 C) and the volume makes up 99 percent or more of the total volume. "Flashpoint" is the minimum temperature at which a liquid gives off enough vapor to ignite. "Hazardous Chemical" includes any chemical for which there is statistically significant evidence based on at least one study conducted in accordance with established scientific principles that acute or chronic health effects may occur in exposed employees. The term "health hazard" includes chemicals that are carcinogens, toxic or highly toxic agents, reproductive toxins, irritants, corrosive, sensitizers, hepatoxins, nephpotoxins, and neurotoxins, agents which act on 2
the hematopoietic system and agents that damage the lungs, skin, eyes or mucous membranes. "Laboratory Scale" means work with substances in containers or other handling requirements which is easily performed by one person. "Laboratory Use" is the use of chemicals when all of the following conditions are met: 1. Use is carried out on a "laboratory scale" 2. Multiple chemical procedures or chemicals are used 3. The procedures are not part of a production process 4. Protective lab practices and equipment (PPE) are available and used to minimize employee exposures. "Oxidizer" is any chemical that initiates or promotes combustion in other materials. (See GHS symbols) "Reactive" is any unstable chemical which will polymerize, decompose, condense or become self-reactive under conditions of shock, pressure or temperature. (See GHS Symbols) "Permissible Exposure Limit (PEL)" is the maximum 8-hour time-weighted average concentration of a substance which an employee can be exposed to as established by OSHA. Chemical Hygiene Plan The purpose of the written Chemical Hygiene Plan is to protect employees from health hazards associated with hazardous chemicals in the laboratory and shall be readily available to all laboratory personnel. A. Laboratory Personnel Chisago Lakes ISD #2144 is responsible for developing and supporting a broad-based chemical hygiene program that will protect its staff and students from the health effects associated with exposure to hazardous chemicals. Chisago Lakes ISD #2144 has designated Steve Vopatek as its Chemical Hygiene Officer. B. Employee Exposure Determination The Chemical Hygiene Officer has determined that no school district employee s exposure level exceeds the action level or Personal Exposure Limit (PEL). C. Procurement The Chemical Hygiene Officer has obtained all the applicable Safety Data Sheets (SDS) and they are on file at the District Office (Electronic) and the science departments at both 3
the High School and Middle School (hard copy). Currently, chemicals are purchased at both the High School and Middle School science departments. The Chemical Hygiene Officer annually takes a chemical inventory for both the High School & Middle School and oversees the proper labeling of all chemicals. This inventory is on file at the high school in the Chemical Storeroom. D. General Lab Practices In general, laboratory personnel shall minimize all exposures to hazardous chemicals and never underestimate the risk involved. The Safety Data Sheet (SDS) for any chemical being used should be carefully read prior to any staff or student use. Any unknown chemicals or mixtures should be assumed toxic and placed in the appropriate area for disposal by the Chemical Hygiene Officer (CHO). In addition to existing standard operating procedures and practices within the laboratories, the following are considered good practices to follow: Promote housekeeping within the laboratory by cleaning up work benches and returning chemicals to designated storage areas on a daily basis. Minimize the use of flammable or combustible liquids near any open flame or other ignition source. Comply with the District s Methanol Control Policy. Identify any special activities or procedures or extremely hazardous chemicals which require preliminary approval. Factors to consider include quantities used, chemical and physical properties of the chemical, toxicity of the chemical and the potential for exposure. The Safety Data Sheets (SDS) should be consulted prior to any use. The MSFM (Minnesota State Fire Marshall) list of dangerous substances must also be consulted prior to use. The proposed educational benefit of using such chemicals should always be carefully weighed against the potential dangers inherent in using such materials. Designate special areas for working with extremely hazardous chemicals (i.e. carcinogens, acute toxins). Fume hoods should be used with any chemical posing a threat in the vapor phase as indicated in the SDS. If secondary solutions are mixed, they must be labeled with GHS (Global Harmonization System) compliant labels. NFPA (National Fire Prevention Assn) 4 Diamond labels work best for this purpose. Conduct frequent inspections within the laboratory to identify any unsafe work practices or conditions. Prohibit any eating or drinking in the laboratory. 4
Prohibit any mouth pipeting. Pipet pumps or mechanical fillers should always be used. Protect against broken glass or glassware implosions. Deposit all broken glass in the container labeled for glass recycling. Avoid working alone in the laboratory or chemical storeroom. Use the buddy system.always let another staff member know that you will be working in the chemical storeroom. Safety Glasses and any other appropriate Personal Protective Equipment (PPE) must be utilized by all staff and students when in the lab or in the Chemical Storeroom. Refrigerators must be labeled specifically for chemical storage. Food items or beverages must not be stored in designated chemical storage refrigerators. E. Control Measures Chisago Lakes ISD #2144 shall provide for appropriate control measures where employees are routinely exposed to a substance above its respective action level or PEL. Currently there are no employees routinely exposed to a substance above its respective action level or PEL. This will be monitored and employees may be tested every two years. Fume hoods are located in SC1 & SC2 at the High School. Chemical storage has 24 hour ventilation at the high school and at the middle school. Fume hood face velocities are measured and recorded twice a year. Test results are conspicuously posted on the hood cabinet. Personal Protective Equipment. Personal protective equipment (PPE) acts as a barrier preventing or minimizing chemical exposure to the employee. Chisago Lakes ISD #2144 provides its instructors with lab coats, individualized safety glasses, vinyl gloves. Certain employees who are exposed to toxic materials outside the classroom or lab are equipped with OSHA approved respirators with cartridges appropriate to the chemicals they may be exposed to. These employees have received training regarding the use and maintenance of their employer-provided respirators. Laboratory safety showers and eye wash stations are available in all the High School science rooms. The two science rooms in the 6 th grade addition of the Middle School also have laboratory safety showers and eyewash stations. F. Chemical Storage Chisago Lakes ISD #2144 has designated chemical storage areas or chemical storage cabinets for all flammable, reactive or toxic chemicals at both the High School and the 5
Middle School. The pattern of storage is based on the recommendations of Flinn Scientific. The chemical storage program should include the following: G. Labeling Do not store incompatible chemicals together. Keep oxidizers separate. Be sure the container is compatible with the chemical. Properly ventilate the chemical storage cabinet and avoid direct heat or sunlight. Do not stockpile chemicals, store as little as possible. Clean any residual material from outside of container. Use a secondary container when transporting a chemical container, for containers with broken seals, or for highly toxic chemicals. Periodically inspect the integrity of the container. Compromised containers must be immediately replaced. Store compressed gas cylinders away from any heat sources, cap fastened, and cylinder securely attached to wall or other fixed object. (See Compressed Gas Policy) Chisago Lakes ISD #2144 requires all hazardous chemicals to be properly labeled. The label should include the chemical name, hazardous properties and an emergency phone number for further information. The label should be easily cross-referenced back to the appropriate SDS for that chemical. H. Disposal The primary handler of hazardous waste will be: Veolia Environmental Services Technical Solutions LLC 3230 101 st Avenue NE Blaine, MN 55449 Phone: 763-786-3660 The following are the requirements of chemical disposal: All wastes properly labeled (DOT regulations). Verify mixed wastes are compatible with each other. Pouring of chemicals down the drain, particularly strong acids/bases or highly 6
toxic substances is prohibited. (See Disposal Policy) Chemicals should not be left inside the fume hood to evaporate. The drain systems in the Science classrooms and the Chemical Storeroom at the High School are equipped with an Acid Neutralization Pit which requires periodic maintenance. There must be an annual inspection of the limestone rock medium in the pit to insure that it is free of silt or algal growth and that the amount of active limestone present in the pit is consistent with the pit s design. If the limestone rock in the pit is found to be covered with silt or algal growth, the rock must be removed and cleaned using high pressure water and then replaced in the pit. If the amount of non-degraded limestone in the pit is less than the specifications for the pit allow, the necessary amount of limestone must be added to bring the pit up to operational capacity. Instructors are directed to neutralize any acidic solution of ph = 3 or lower prior to discarding it in the drains. The acid neutralization pit is designed as a safety feature to prevent the accidental addition of highly acidic solutions to the municipal sewer system. Allowing untreated acidic solutions to enter the waste stream without prior neutralization is a violation of state law. The acid neutralization pit was not designed as a primary treatment area for acidic wastes. Prior to discarding acid solutions, preliminary neutralization should be accomplished using sodium carbonate, sodium bicarbonate or similar. I. Emergency Plan Refer to the Emergency Procedures flip chart - Hazardous Materials Release (040). Medical Surveillance Program Chisago Lakes ISD #2144 shall provide medical consultation to determine the necessity for a medical exam to any employees exposed during a spill, leak or other occurrence resulting in the likelihood of a hazardous exposure. In addition, Chisago Lakes ISD #2144 shall provide a medical examination for the employee under the following circumstances: 1. Whenever an employee develops signs or symptoms associated with a hazardous chemical to which the employee may have been exposed in the laboratory. 2. Where exposure monitoring reveals an exposure level routinely above the action level (or in the absence of an action level, the PEL) for an OSHA regulated substance for which there are exposure monitoring and medical surveillance requirements, medical surveillance will be established for the affected employee as prescribed by the particular standard. 7
The Chemical Hygiene Officer will be contacted whenever the need for medical consultation or examination occurs, or when there is uncertainty as to whether any of the above criteria have been met. All medical examinations and consultations will be performed by or under the direct supervision of a licensed physician and will be provided without cost to the employee, without loss of pay and at a reasonable time and place. The Chemical Hygiene Officer will provide the examining physician with the following information: the identity of the hazardous chemical(s) to which the employee may have been exposed; a description of the conditions under which the exposure occurred including quantitative exposure data, if available; and a description of the signs and symptoms of exposure that the employee is experiencing, if any. The examining physician will provide Chisago Lakes ISD #2144 a written report including the following: any recommendation for further medical follow-up; the results of the medical examination and any associated tests; any medical condition which may be revealed in the course of the examination which may place the employee at increased risk as a results of exposure to a hazardous chemical found in the workplace, and a statement that the employee has been informed by the physician of the results of the consultation or medical examination and any medical condition that may require further examination or treatment. The written physician's opinion will not reveal specific findings of diagnoses unrelated to any occupational exposure. Training Program Chisago Lakes ISD #2144 shall train all laboratory personnel to ensure that they are apprised of the hazards of chemicals present in their laboratory and that they know how to control exposure to such chemicals. Training shall be provided at the time of initial assignment to a work area where hazardous chemicals are present and prior to any assignments involving new potential 8
exposure situations. A two hour comprehensive training session was provided to all high school and middle school science teachers on October 16, 2013. This training focused on the new Global Harmonization System and how it impacts District employees. The District will provide refresher training annually. The training program will include, at a minimum, the following: 1. Review of the OSHA standard (Chemical Hygiene Plan). 2. Review of the Chemical Hygiene Plan and its location. 3. Toxicity, hazards, routes of exposure, signs and symptoms and health effects of the chemicals. 4. Review of action levels, Personal Exposure Limits (PELS) or other appropriate limits for each chemical. 5. Review of Safety Data Sheet (SDS) information available for each chemical (i.e. hazards, handling, storage, and disposal). 6. Methods to detect the presence or release of hazardous chemicals (i.e. air monitoring, odors, visual appearance). 7. Good laboratory practices. 8. Control measures. 9. Emergency response actions. Record keeping Training Records Chisago Lakes ISD #2144 shall retain training records for each employee for a period of five years. Medical Records Chisago Lakes ISD #2144 shall maintain each employee's medical records for the duration of employment plus 30 years. If an employee has worked less than one year, the School District is not required to retain the medical records and should turn them over to the employee at the time of their departure. (Refer to OSHA 29 CFR 1910.20 - Access to Employee and Exposure Medical Records.) Exposure Records Chisago Lakes ISD #2144 shall retain all employee exposure (monitoring) records for 30 years (minimum). 9
