A. Only when working at heights over 50 feet.a
B. When operating heavy machinery.
C. When in a public easement.
D. During night operations only.
Correct Answer – C
Rationale – The provided content explicitly states that a high-visibility vest is required when in a
public easement.
2. How long after welding is completed must a spotter continue to monitor a site for
potential fires?
A. 30 minutes.
B. 1 hour.
C. 2 hours.
D. 4 hours.
Correct Answer – B
Rationale – The content specifies a mandatory 1-hour fire watch period after welding is finished.
, 3. Which of the following actions will NOT prevent a fire while welding in a fire-prone
area?
A. Wetting down combustible materials.
B. Using a fire blanket.
C. Chipping Slag.
D. Having a fire extinguisher present.
Correct Answer – C
Rationale – Chipping slag is a post-weld cleaning process and is not a fire prevention measure.
4. How is an exothermic weld performed?
A. By using an electric arc welder.
B. By an oxyacetylene torch.
