When a CO leak is detected, shelter-in-place was described in On-Site Test. What credit does choosing shelter-in-place receive?

• A. No credit
• B. Full credit
• C. Partial credit
• D. Double credit

Answer: (A)

The main idea here is choosing a protective action that quickly reduces exposure to a hazardous gas. For a CO leak, moving people to fresh outdoor air and evacuating from the contaminated area is the action that most effectively lowers risk and aligns with the expected response in the On-Site Test rubric. Sheltering-in-place keeps people inside, where CO can continue to accumulate, so it doesn’t achieve the rapid reduction in exposure that the scoring favors. Because the test’s rubric rewards actions that promptly minimize exposure, choosing shelter-in-place earns no credit in this scenario. This doesn’t mean shelter-in-place is never appropriate in other situations, but in this CO leak On-Site Test, evacuation to outside air is the protective action that’s credited.
