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 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 K = Air line hood or mask, gloves, full chemical suit, boots X = Ask Supervisor Note: before using any respirator contact EH&S for assistance.
