Spotlight on Safety: Treat Contractors as Invited Guests

Spotlight on Safety
John Herber
Not only am I often a contractor at client sites, but about 30% of my career has been spent working directly with construction contractors who have been key to the success of many projects. My father was a construction worker for 35 years and although he didn’t work in chemical plants, he worked around many different hazardous operations. It is the responsibility of the companies that hire us to keep me, my father, and our fellow contractors safe.
