The hazard
Well sites put flammable gas and liquids, possible toxic gas like hydrogen sulfide, high pressure, heavy equipment and several crews in one small area. Conditions can change fast, and one missed step can lead to a fire, an explosion or a toxic release. Knowing the hazards and looking out for each other is how everyone gets home.
The action
Your hazard communication training must include the methods and observations used to detect a chemical release, such as employer monitoring, continuous monitoring devices and the look or odor of a chemical being released. Wear your personal gas monitor where required, check it the way you were trained and know what each alarm means. Some gases, like hydrogen sulfide, can dull your sense of smell, so never use your nose to decide an area is safe. (29 CFR 1910.1200(h)(3)(i))
ASK THE CREW
What does each alarm on your gas monitor mean, and what do you do when it goes off?
