Question 38 CEL01 - Chief Engineer - Limited

The Correct Answer is B ### 2. Explanation for why option B ("1,2,3,4,5") is correct. Option B is correct because the periodic tests and inspections required under 46 CFR (Subchapter F, usually 59.20-15 or similar sections covering automatic auxiliary boiler safety controls) mandate a comprehensive check of all safety features, operational timing, and notification systems associated with the flame safeguard control. All five listed components are critical safety checks: * **1) Flame failure** and **2) Ignition failure:** These are the primary safety events the system is designed to detect and respond to by securing fuel. Both scenarios must be simulated and verified during inspection. * **5) Shutdown times:** The speed (response time) at which the flame safeguard device secures the fuel supply after a failure must be verified to be within established regulatory limits (usually a few seconds) to prevent dangerous accumulation of fuel, making this an essential operational safety check. * **3) Audible alarm of shutdown** and **4) Visual indication of shutdown:** These are mandatory notification requirements. Ship personnel must be immediately notified (audibly) and provided a precise indication (visually, via annunciator or display) of the cause of the boiler shutdown to facilitate prompt and safe corrective action. Omitting any of these five checks would result in an incomplete or non-compliant periodic inspection of the automated boiler controls. ### 3. Explanation for why each of the other options is incorrect. * **A) 1,2,3,4:** This option is incorrect because it omits **5) Shutdown times**. The operational response time of the flame safeguard system is a critical safety parameter that must be verified against regulatory and manufacturer limits during testing. * **C) 1,2,3,5:** This option is incorrect because it omits **4) Visual indication of shutdown**. Accurate visual annunciation is required for personnel to correctly identify the cause of the safety shutdown (e.g., flame failure, high pressure trip, low water), which is vital for safe and timely troubleshooting. * **D) 1,2,5:** This option is significantly incorrect because it omits both the **3) Audible alarm** and **4) Visual indication**. Without immediate audible notification and visual identification of the failure, the system fails to meet crucial mandatory standards for personnel safety and operational awareness required by the regulations.
