HazCom: Hazard communication

Hazard communication is the program that tells workers about the chemicals they use, through labels, safety data sheets and training.

Also calledHazCom, right to know, chemical hazard communication, GHS labeling

What it means

Hazard communication, often called HazCom, is a site's program for telling workers what chemicals are around and what those chemicals can do. It rests on three things: labels on containers, safety data sheets and worker training.

In the US, the rule is OSHA 29 CFR 1910.1200. Check the current rule. A written program usually lists the chemicals on site, says who keeps the sheets and explains how new products are brought in.

It also covers chemicals in unlabeled or secondary containers, and the hazards of non-routine tasks, like cleaning a tank.

Why it matters

A worker can't protect themselves from a hazard they don't know about. HazCom is how a company gets that information from the label and the sheet to the person holding the container. It's also a common thing for an inspector to ask about.

What it looks like on a site

  • The site keeps a written program and a list of the chemicals used.
  • Containers are labeled, including the spray bottle someone filled from a drum.
  • Safety data sheets are easy to reach for every shift.
  • New hires are trained on the labels and sheets before they handle chemicals, and again when a new hazard shows up.
  • Training records are kept and reviewed.

Common questions

Is hazard communication the same as the right to know?
Right to know is the older phrase for the same idea: workers are entitled to learn about the chemicals they work with. HazCom is the modern name for the program.
Do small amounts of chemicals count?
It depends on the product and the current rule. Some everyday items are treated differently. Check the rule and ask your safety lead.
