It's important to develop plans and conduct drills for dealing with emergencies such as fire, explosion, poisoning, chemical spill, vapor release, and personal contamination.
Not only should it be required that all accidents or incidents be reported, they should also be evaluated by the departmental safety committee and discussed at departmental safety meetings.
Safety meetings are an integral part of a good safety program. You need to have a time when you and your colleagues can get together and focus on safety issues.
