Which of the following is a key fire prevention measure on a ship?

Regular maintenance and inspection of fire safety equipment is a fundamental measure for fire prevention on a ship. Ensuring that equipment such as fire extinguishers, alarms, and sprinkler systems are functioning properly is vital for minimizing the risk of a fire and ensuring the safety of all onboard. Regular checks can identify worn-out or damaged equipment that might fail in an emergency, thus maintaining operational readiness.

For fire prevention, having well-maintained and readily accessible fire safety equipment can significantly mitigate the effects of a fire should one occur. Proper functionality of alarms, extinguishers, and other systems allows for an immediate response, containing potential fire threats before they escalate.

Other measures, while beneficial, may not directly address the overarching need for well-functioning safety systems. For instance, increasing the crew number may enhance response capabilities but does not substitute for the necessity of properly functioning fire equipment. Limiting electrical appliances and training in cooking may contribute to reducing fire risks but are not comprehensive preventive measures without the support of well-maintained safety equipment.
