Question 210Safety & Environmental - 1st Asst/Chief70% to pass
While donning the positive pressure self-contained breathing apparatus, you discover that the air cylinder pressure gage and the regulator pressure gage differ from each other by 500 psi. Which of the listed actions should you consider as appropriate?
AI Explanation
The correct answer is D) Assume that the lower gage reading is correct.
The reasoning behind this is that when there is a discrepancy between the air cylinder pressure gage and the regulator pressure gage, the lower reading should be considered the accurate one. This is because the regulator gage may indicate a higher pressure due to factors such as a malfunction or calibration issue, but the lower cylinder pressure gage reading represents the actual amount of available air in the cylinder, which is the critical factor for determining the safe duration of use.
The other options are incorrect because replacing the gages or the air cylinder may not be necessary, and taking the average of the two readings would not provide the most conservative and safe assumption about the air supply.
