What is a common indicator of a potential fire hazard onboard?

Unusual heat in equipment or areas serves as a significant indicator of a potential fire hazard onboard. Elevated temperatures can signal that machinery is malfunctioning or that flammable materials are present and heating up, which increases the risk of combustion. Monitoring equipment temperatures is a crucial aspect of fire prevention; if heat levels rise beyond normal operating ranges, it may indicate overheating, friction, or other failures that could lead to a fire. This proactive approach helps personnel identify and address issues before they escalate into serious fire hazards, reinforcing the importance of vigilance regarding temperature fluctuations aboard vessels.
