Why do managers make a commitment to safety?

Reason No. 3 They want to fulfill the legal imperative.

This is the least effective strategy. The primary goal for managers is to fulfill the obligation to comply with OSHA rules. Managers want to stay out of trouble, so they do only what has to be done to meet minimum requirements. Safety is not a priority or value, but thought of as a bother more than anything else: just the cost of doing business. Safety strategies are typically reactive because safety is not a problem unless there is an accident. OSHA may be considered the "bad guy" because management doesn't understand how OSHA can offer consultation services as well as enforcement activities.

This is self explanatory - which means that what we are striving here is merely to comply.
