E N D
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
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 the yearly basis.
Material Safety Data Sheets - MSDS • A Material Safety Data Sheet or MSDS is information provided by the manufacturer and maintain 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.
Material Safety Data Sheets - MSDS • Each area must maintain a current MSDS for each chemical or compound being stored or used in the workshops or work areas. • Each MSDS must be available whenever the chemical is being used. • Everyone should know how to use and understand MSDS’s and where they are located.

Important MSDS Information • An MSDS is a good source to determine: • Proper Personal Protective Equipment (PPE). • Labeling requirements. • Storage requirements. • READ an MSDS before using a new chemical or unsure of the possible hazards.
MSDS Emergency In an emergency and you cannot retrieve an MSDS, you can be obtained it by calling the 3E Company’s 24 Hour phone #: 800-451-8346 Or 760-602-8703
Chemical Storage • Separate incompatible chemicals. • Separate oxidizers (like some Fertilizers) from flammables (Solvents, Paints) • Separate flammable liquids, acids and bases • Provide earthquake restraints for all open shelving when storing chemicals. • Secondary containment needs to be provide if there is a risk of a release into the environment.
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!
Flammable Liquids Storage • If a 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.
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 (Muriatic Acid) • Oxidizing (Nitric Acid)
Bases Storage • Store in secondary containment • Store away from acids and solvents • Label cabinets “Base” with 3” letters • Examples • Hydroxides (Lime, Caustic Soda) • Ammonia • Bleach
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
Chemical Labeling • All containers in the work area must be properly labeled with the name of the material being stored in the container. This includes non-hazardous materials such as: • Water • Detergent • Window Cleaner • Full name with “no” abbreviations.
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.
Chemical Labeling • Consult the MSDS or the manufacturer’s label for accurate labeling information regarding physical and health hazards.
HMIS “Hazardous Materials Identification System” 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.
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.
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 temperaturesbefore 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.
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 the 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.

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