In the last several weeks I have been writing about respirators and how they should be managed when NOT in use. In this article, I will be discussing respirators when we use them in emergency conditions or potentially emergency conditions. In my world of process safety management, I see a lot of misguided logic in respirator decisions that I hope to clear up with this brief article. But there is NOTHING I can say here that any reader should not CONSULT with their respirator program administrator before acting upon it.
