2 Chemical Inventory Each area must maintain a complete, accurate and up to date chemical inventory. The inventory should include: All Chemicals Hazardous Non-hazardous Compressed Gasses

3 Chemical Inventory When you are doing the inventory, it is a good time to discard any chemicals that: Are expired. Are no longer being used. Have containers that have been compromised, i.e. Cracked lid. Have labels that are illegible. Submit your updated inventory to EH&S on a yearly basis.

4 Safety Data Sheets - SDS A Safety Data Sheet or SDS is information provided by the manufacturer and maintained by the employer to inform employees of the possible hazards associated with chemicals being used in their work area. It is part of a hazard communication program.

5 Safety Data Sheets - SDS Each area must maintain a current SDS for each chemical or compound being stored or used in the shop/studio. Each SDS must be available whenever the chemical is being used. Everyone should know how to use and understand SDS s and where they are located.

6 Global Harmonization Standard (GHS) The revised Hazard Communication Program incorporates the GHS and refers to MSDS as Safety Data Sheets (SDS). It also requires that the information on the SDS is presented using consistent headings in a specified sequence.

7 SDS Information Section 1. Identification Section 2. Hazard(s) identification Section 3. Composition/information on ingredients Section 4. First-Aid measures Section 5. Fire-fighting measures Section 6. Accidental release measures Section 7. Handling and storage Section 8. Exposure controls/personal protection Section 9. Physical and chemical properties Section 10. Stability and reactivity Section 11. Toxicological information Section 12. Ecological information Section 13. Disposal considerations Section 14. Transport information Section 15. Regulatory information Section 16. Other information, including date of preparation or last revision

8 Important SDS Information An SDS is a good source to determine: Proper Personal Protective Equipment (PPE). Labeling requirements. Storage requirements. READ an SDS before using a new chemical or unsure of the possible hazards.

9 SDS Emergency In an emergency and you cannot retrieve an MSDS/SDS, you can be obtained it by calling the 3E Company s 24 Hour phone #: Or

10 Chemical Storage Separate incompatible chemicals. Separate oxidizers from flammables (Solvents, Paints) Separate flammable liquids, acids and bases Provide earthquake restraints for all shelving when storing chemicals or glassware. Secondary containment needs to be provided if there is a risk of a release into the environment.

11 Chemical Storage The storage container MUST be compatible with material it is holding. Example: Metal containers cannot be used for acids and bases. Food containers MUST NEVER BE USED!

12 No earthquake restraints!

13 Flammable Liquids Storage If an area has quantities greater than 10 gallons, they must be stored in an approved flammable liquids storage cabinet. Containers that can be shattered or punctured easily must be in secondary containment. Do not store flammables with acids or bases.

14 Acids Storage Store in secondary containment Label cabinets Acid with 3 letters Store acids of different classes in separate secondary containment Organic (Acetic Acid) Inorganic (Hydrochloric Acid) Oxidizing (Nitric Acid)

15 Bases Storage Store in secondary containment Store away from acids and solvents Label cabinets Base with 3 letters Examples Hydroxides Ammonia Bleach

16 Compressed Gasses Storage Must be upright and restrained At least two chains Separate incompatible gasses Flammable & Oxidizing by 20 feet Keep caps on while in transportation or in storage

17 Chemical Labeling All containers in the studio must be properly labeled with the name of the material being stored in the container. This includes non-hazardous materials such as: Water Dyes Aqueous Salt Solutions Full name with no abbreviations.

18 Chemical Labeling Containers of hazardous materials must not only include the name of the material but also the physical and health hazards associated with the use of the material.

19 Chemical Labeling Consult the SDS or the manufacturer s label for accurate labeling information regarding physical and health hazards.

20 GHS Pictograms and Hazard Classes The GHS creates globally recognized categories and pictograms for manufactures to communicate hazards on chemicals bottles.

22 Hazardous Materials Identification System HMIS The HMIS rating is a color-coded, alphanumeric system which gives information about the health, flammability and reactivity of the chemical in question. The system rates a material from a minimal hazard through a serious hazard. It also recommends the appropriate personal protective equipment to be worn when handling the particular chemical.

23 Example of HMIS

24 HMIS Health 0 - Minimal Hazard Not significant risk to health. 1 - Slight Hazard Irritation or minor reversible injury possible. 2 - Moderate Hazard Temporary or minor injury may occur. 3 - Serious Hazard Major injury likely unless prompt action is taken and medical treatment is given. 4 - Severe Hazard Life-threatening, major or permanent damage may result from single or repeated over exposures.

25 HMIS Flammability 0 - Minimal Hazard Materials that will not burn. Usually includes any material that will not burn in air when exposed to a temperature of 1500 F for a period of 5 minutes 1 - Slight Hazard Materials that must be preheated before ignition can occur. 2 - Moderate Hazard Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur. 3 - Serious Hazard Materials capable of ignition under almost all ambient temperature conditions. 4 - Severe Hazard Materials that will rapidly or completely vaporize at atmospheric pressure and normal ambient temperatures with a flashpoint below 73 F. Materials may ignite spontaneously with air.

26 HMIS Reactivity 0 - Minimal Hazard Materials that are normally stable even under fire conditions. 1 - Slight Hazard Materials that are normally stable but that can become unstable at elevated temperatures and pressures. 2 - Moderate Hazard Materials that readily undergo violent chemical change at elevated temperatures and pressures. These materials may also react violently with water. 3 - Serious Hazard Materials that are capable of detonation or explosive decomposition but require a strong initiating source or materials that react explosively with water. 4 - Severe Hazard Materials that are readily capable of detonation or explosive decomposition or explosive reaction at normal temperatures and pressures.

29 Be Safe, Act Responsibly, Accidents Really Do Happen

30 Frequently Asked Questions Q. How do I know what is the appropriate Personal Protective Equipment (PPE) that I should use? A. Check the SDS or sometimes the manufacture s label will have the information. MSDS/SDS are a great tool in deciding how to label your containers, too.

31 Frequently Asked Questions Q. Do I need to use the blue, red, yellow and white HMIS labels? No, it would be ideal if everyone did but sometimes it is not practical. You can use whatever method you can. Be it masking tape or sharpies. As long as all the information is there, it is legible and stays on the container, you are fine.

32 Frequently Asked Questions Q. Why do I need to label something that has just plain water in it? A. A container with water looks just like a container with Hydrochloric Acid or any other clear liquid. You can t tell if something is dangerous just by looking at it. That is the purpose of Hazard Communication. Communicate what is hazardous and what is not.
