What Must be Labeled and Why is it Required in Chemical labeling?

The OSHA Hazard Communication Standard (HCS) specially mandates that all containers of dangerous materials be labeled with an proper warning. While this warning does not have to consist of all of the information enclosed on the Material Safety Data Sheet, it does have to communicate critical information to the user.

The Hazardous Materials Identification Guide (HMIG) or Hazardous Materials Information System (HMIS) was developing as a tool to fulfill with the HCS and has employees who should handle dangerous chemicals in the workplace as the proposed audience. HMIS includes hazard appraisal, a rating system for sharp and constant health, flammability and physical hazards. These labels provide at-a-glance of information on the risk and the suitable personal protective equipment (PPE). HMIS was developed by the National Paint and Coatings Association (NPCA).

National Fire Protection Association (NFPA) is a kind of fire protection danger warning system designed to provide quick, clear information to emergency situation responders on materials under conditions of fire, chemical spill, or other emergency situations. Like HMIS, it includes labels and a numerical ranking system, but the fundamental purpose of the label information is different. Therefore, the numbers allocated in the NFPA system imagine that a fire is present. No such assumption grasps in the HMIG/HMIS system. For this reason, the numbers that are allocated to the flammability, health, and reactivity hazards may differ between the NFPA and HMIG systems, even for the same exact chemical.

The following are some examples of chemical labeling schemes used recently. At a minimum level, all chemical containers must include:

1. Name or characteristics of the Chemical,
2. Proper Hazard Warnings, (e.g., corrosive, poison, flammable, oxidizer, explosive)
3. NFPA 704 or Hazardous Materials Information System (HMIS) placards, etc.
