Summary of HMIS Ratings

I. Health Hazard Rating

0     Minimal Hazard
No 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 exposures.

Use of an asterisk (*) or other designation indicates that There may be chronic health effects present. See safety File on the product.

II. Flammability Hazard Rating

0     Minimal Hazard
Materials that are normally stable and will not burn unless heated.
1      Slight Hazard Materials that must be preheated before ignition will occur. Flammable liquids in this category will have flash points (the lowest temperature at which ignition will occur) at or above 200' F (NFPA Class IIIB).
2     Moderate Hazard Material that must be moderately heated before ignition will occur. including flammable liquids with flash points at or above 100' F and below 200'F (NFPA Class II & Class IIIA)
3     Serious Hazard Materials capable of ignition under almost all normal temperature conditions, including flammable liquids with flash points below 73'F and boiling points above 100'F as well as liquids with flash points between 73'F and 100'F (NFPA Class 1B and 1C)
4     Severe Hazard Very flammable gases or very volatile flammable liquids with flash points below 73'F and boiling points below 100'F (NFPA Class 1A)

III. Reactivity Hazard Rating

0     Minimal Hazard
Materials that are normally stable, even under fire conditions, and will not react with water.
1     Slight HazardMaterials that are normally stable but can become unstable at high temperatures and pressures. These materials may react with water but they will not release energy violently
2     Moderate HazardMaterials that, in themselves, are normally unstable and will readily undergo violent chemical change but will not detonate. These materials may also react violently with water .
3     Serious HazardMaterials that are capable of detonation or explosive reaction but require a strong initiating source or must be heated under confinement before initiation, or materials that react explosively with water.
4     Severe Hazard Materials that are readily capable of detonation or explosive decomposition at normal temperatures and pressures.

IV. Chronic Effects Information

Chronic health effects are not rated because of the complex issues involved and the lack of standardized classifications and tests. However, based on information provided by the supplier, the Presence of chronic effects may be indicated by (1) use of an Asterisk (*) or other designation after the health hazard rating corresponding to other information that may be available: or (2) use of written warnings in the upper white section of the HMIS label.

V. Personal Protective Equipment

Information provided by the supplier will be used by the employer to determine the proper personal protective equipment.
