21. Hazard Communication
 Color coded system

22. Labels - Basics
 Identity of the hazardous chemical(s)
 chemical label is your primary source of
information regarding the product.
 Appropriate hazard warnings

23. Labels & Other Information
 Appropriate personal protective equipment
 Signal word - Danger!, Warning!, or Caution!
 Statement of hazard
 Instructions in case of contact or exposure
 First-Aid or antidote
 Instructions in case of fire, spill, or leak
 Instructions for container handling and storage
 Never remove label, and if transferred to a secondary
container, label the bottle (not the lid) with
appropriate information - chemical name, etc.

24. HMIS Label - Example Secondary
Labeling System

25. Labels- Symbols and Pictures

26. Material Safety Data Sheets
(MSDS’s)
 Chemical document put out by
manufacturer detailing
