Question 1
A site fuel truck is parked at a temporary fueling area to refill an excavator. The operator leaves the excavator idling to keep the cab heater running while the nozzle is in the tank. Which action does the standard require?
Show answer and source
Answer: D. Shut off the excavator's motor for the entire fueling operation
The standard requires the motors of all equipment being fueled to be shut off during fueling. A nearby extinguisher, fire watch, or bonding does not replace that requirement.
Answer D rests on
29 CFR 1926.152(g)(10)(opens ecfr.gov in a new tab)“The motors of all equipment being fueled shall be shut off during the fueling operation.”
Question 2
A chemical tank at a construction staging yard begins leaking onto the ground. The site's designated first responders at the operations level arrive and are expected to act as part of the initial response. Which action is consistent with their role?
Show answer and source
Answer: C. Contain the release from a safe distance and keep it from spreading
Operations-level responders respond defensively, containing the release from a safe distance, keeping it from spreading and preventing exposures. Plugging or patching at the point of release is the more aggressive role of a hazardous materials technician, so it is wrong for this level.
Answer C rests on
29 CFR 1910.120(q)(6)(ii)(opens ecfr.gov in a new tab)“They are trained to respond in a defensive fashion without actually trying to stop the release. Their function is to contain the release from a safe distance, keep it from spreading, and prevent exposures.”
Question 3
A laborer on a framing crew is taken to a hospital after a fall from a ladder. He is admitted overnight only so that physicians can watch for delayed symptoms and run imaging scans. No treatment is given, and he is released the next morning. The safety technician is deciding whether this admission triggers a report to OSHA as an in-patient hospitalization. What is required?
Show answer and source
Answer: A. No report is required for this admission, because it involved only observation or diagnostic testing
The standard says an in-patient hospitalization involving only observation or diagnostic testing does not have to be reported; only hospitalizations involving care or treatment must be. The overnight stay alone, or the lost time afterward, does not change that.
Answer A rests on
29 CFR 1904.39(b)(10)(opens ecfr.gov in a new tab)“No, you do not have to report an in-patient hospitalization that involves only observation or diagnostic testing. You must only report to OSHA each in-patient hospitalization that involves care or treatment.”
