Hazardous Materials Identification System (HMIS)
(Click on image above to enlarge.)
The HMIS label, like the NFPA label, provides information on health, flammability, and reactivity. Along with each of these categories is a number ranging from 4 to 0, with 4 being the most hazardous and 0 being the least hazardous.
Personal Protective Equipment
In addition to the three hazards mentioned above, the HMIS label provides information on what type of personal protective equipment (PPE) you should use. In this space, you will find a letter corresponding to a particular combination of PPE to use.

Additional Information
Finally, the HMIS label provides information regarding route of entry, health hazards, physical hazards, and target organs. This information can be found to the left of the other hazard information.
Route of Entry: This is the way the chemical will get into your body (i.e., ingestion, inhalation, or absorption).
Health Hazards: These are effects which may occur if you are exposed to a chemical (e.g., acutely toxic, corrosive, or irritant).
Physical Hazards: These are non-health related characteristics which make the chemical hazardous (e.g., explosive, oxidizer, or flammable).
Target Organs: These are organs that may be affected if you are exposed to the chemical (e.g., central nervous system, liver, or kidneys).
