In accordance with Coast Guard Regulations (46 CFR), water level controls utilized in a small automatically fired auxiliary heating boiler shall be tested __________.
• 46 CFR requirements for automatic auxiliary heating boilers • Purpose of low water level safety controls in boilers • How functional testing of safety devices is normally carried out on board
• Which option actually proves that the low-water cutoff device will work under real operating conditions? • Which method might be discouraged because it could hide a problem or fail to test the full system? • Which choices sound more like timing or administrative actions rather than a true safety-device test?
• Identify which choice involves a direct change in actual water level rather than paperwork or timing only • Eliminate any answer that focuses only on shutdown time instead of function of the control • Ask: which method would the Coast Guard most likely require to demonstrate operation of the low-water cutoff beyond mere simulation?
