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: 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. Full name with “no” abbreviations.

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. 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. 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.

Example of HMIS

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

HMIS Flammability 0 - Minimal Hazard 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 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 1 - Slight Hazard Materials that must be preheated before ignition can occur. Materials that must be preheated before ignition can occur. 2 - Moderate Hazard 2 - Moderate Hazard Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur. Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur. 3 - Serious Hazard 3 - Serious Hazard Materials capable of ignition under almost all ambient temperature conditions. Materials capable of ignition under almost all ambient temperature conditions. 4 - Severe Hazard 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. 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 0 - Minimal Hazard Materials that are normally stable even under fire conditions. Materials that are normally stable even under fire conditions. 1 - Slight Hazard 1 - Slight Hazard Materials that are normally stable but that can become unstable at elevated temperatures and pressures. Materials that are normally stable but that can become unstable at elevated temperatures and pressures. 2 - Moderate Hazard 2 - Moderate Hazard Materials that readily undergo violent chemical change at elevated temperatures and pressures. These materials may also react violently with water. Materials that readily undergo violent chemical change at elevated temperatures and pressures. These materials may also react violently with water. 3 - Serious Hazard 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. 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 4 - Severe Hazard Materials that are readily capable of detonation or explosive decomposition or explosive reaction at normal temperatures and pressures. 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? 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. A. Check the MSDS or sometimes the manufacture’s label will have the information.

Frequently Asked Questions Q. Do I need to use the blue, red, yellow and white HMIS labels? 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. No, it would be ideal if everyone did but sometimes it is not practical.

Frequently Asked Questions Q. Why do I need to label something has just plain water in it? 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. A. A container with water looks just like a container with Hydrochloric Acid or any other clear liquid.
