What is the hazard rating index on the HMIS label?
The Hazardous Materials Information System (HMIS) is a color and number system. The system uses a color-coded square with four rows in which numbers are used to signal the degree of health hazard, flammability hazard, and reactivity hazard.
What does a hazardous rating of 0 mean?
Level 0 – Materials that offer no unusual hazards upon exposure to fire conditions. A chemical hazard rating at the highest level should be given to a room, unless chemicals are present in very small amounts or are present very infrequently. Flammability. ◆
What does a blue placard mean?
dangerous
Yellow placards indicate the material is an oxidizer; Blue placards indicate the material is dangerous when wet; White placards indicate the material is an inhalation hazard and/or poison; White placards with black stripes indicate miscellaneous hazardous materials.
How do I read HMIS labels?
The white square shows the level of fire hazard the material poses. A “0” signifies that the material is non-flammable. A “1” indicates the material has a flash point above 200ºF, which means it must be exposed to a heat source to ignite. A “2” means the material has a flash point between 100ºF and 200ºF.
