Chlorine gas safety

Chlorine gas safety talk

Chlorine gas is greenish-yellow and smells like bleach.  It is highly corrosive and reacts violently with petroleum products.  It can react with carbon monoxide and other combustible products. Anyone working with or around chlorine gas should have formal training and regular awareness training to know how to safely handle it.

When working with or near chlorine gas be mindful of the following safety reminders and tips:

  • Follow the buddy system: If handling chlorine gas have a second person with you. If something should go wrong, the other person can readily call for help.
  • Wear a respirator: Equipment should meet OSHA requirements.
  • Have an escape plan.
  • Equipment should be inspected, tested and refilled regularly. The local fire department can assist with inspecting and testing the units.
  • Have PPE available in the form of rubber gloves, protective apron, googles, facemask, eye wash station and deluge shower or access to warm water to shower.
  • Have a separate storage room for chlorine. The local fire marshal can serve as a valuable resource to gain information about proper storage of chlorine chemicals.
