What does hazard communication mean in your laboratories? Are there hazard warning signs posted everywhere, are you constantly having to remind lab employees to label their chemical bottles appropriately, or do you need to update the door signs that have not been looked at in years?
There are numerous regulations that stipulate requirements for communicating hazards, some more stringent than others. Of course following the specific regulatory requirements is important and must be done, but otherwise finding a balance between not communicating hazards sufficiently and over labeling/signing can be a challenge. When hazard warnings are posted everywhere they can lose their value and be ignored because the meaning is lost. And on the flip side, if signage is not sufficient, compliance can be lacking because the hazards are not recognized appropriately.
Be sure to evaluate hazard communication in your labs on a regular basis and find the right balance.
