Laboratory Safety
(How to have fun in the lab without
getting hurt)
Know hazard classification

The HMIS label, Like the NFPA 704 diamond, provides hazardous information. Color for type of hazard
and numbers for the degree of the hazard, four being the most hazardous.
In addition the HMIS system provides information on the type of personal protective equipment (PPE)
that should be used when handling this material. In this category a letter is used to indicate what
combination of PPE should be used.
A = Safety glasses
B = Safety glasses, gloves
C = Safety glasses, gloves, chemical apron
D = Face shield, gloves, chemical apron
E = Safety glasses, gloves, dust respirator
F = safety glasses, gloves, chemical apron, dust respirator
G = Safety glasses, gloves, vapor respirator
H = Splash goggles, gloves, chemical apron, vapor respirator
I = Safety glasses, gloves, dust and vapor respirator
J = Splash goggles, gloves, chemical apron, dust and vapor respirator
