According to 46 CFR regulations pertaining to tests and inspections as related to automatic auxiliary boilers, the draft limit control must be checked for proper operation. What statement is true?
• 46 CFR requirements for automatic auxiliary boiler safety devices • Purpose of a draft loss interlock switch in combustion safety • Difference between preventing startup and causing shutdown in boiler protections
• If draft is insufficient, what two different phases of boiler operation could be dangerous: while starting up, while already firing, or both? • In a fully automatic safety system, would it make sense to protect only during startup, only during operation, or during both conditions? Why? • How would the Coast Guard likely structure regulations for a single critical safety device affecting combustion air loss?
• Check in 46 CFR (Subchapter F or I) how many functions the draft loss interlock is required to perform: just shutdown, just lockout on start, or both. • Verify whether the regulation mentions "safety shutdown", "prevention of startup", or a combination of both when draft is inadequate. • Eliminate any choice that explicitly says there is no requirement to test one of the key protective actions if the regulation clearly intends comprehensive protection.
