question # 10
multiple choice
what construction issues might require the services of a hazmat worker?
wood
sheet metal
drywall
hazardous materials

Explanation:

1. Boilermakers specialize in working with large pressure vessels (containers for gases/liquids) like boilers, not roofing, tile work, or structural steel beams.
2. Hazmat (hazardous materials) workers are trained to handle, mitigate, and clean up dangerous substances, so construction issues involving hazardous materials require their services. The other options are standard non-hazardous construction materials.

1. assembles, installs, and repairs large containers that hold gases and liquids
2. hazardous materials
