Chapter 4.D. Interpreting Information from Hazardous Materials Rating Systems for
Product Selection
Introduction
The following chart provides a comparison of the two hazardous materials rating systems that were developed to
provide an awareness of a product’s hazards—the National Fire Protection Association (NFPA) system and the
Hazardous Materials Information System (HMIS).
The information found on product labels and on material safety data sheets (MSDSs) can be used to interpret product
hazards at a glance and to compare product options to find the least-toxic one, as illustrated in the next section,
Chapter 4.E
. For an explanation of each rating, see
Appendix B.3. Interpreting Information from Hazardous
Materials Rating Systems
.
What the NFPA and HMIS rating systems are and how they are used
Both systems display similar color and numerical coding information in the blue, red, and yellow sections, but
different information is listed in the white sections. In newer versions of the HMIS, the yellow color (Reactivity) has
been replaced by orange (Physical Hazard).

How It Is Used
1) On
placards
used on large containers,
doors, and walls to alert people as to
hazards inside.
2) As a rating system on MSDSs.
1) On
labels
used on secondary containers
where there is no manufacturer label.
