Which duty is not a responsibility of the division safety petty officer?

The responsibility of the division safety petty officer primarily revolves around overseeing safety practices and training within the division, rather than the hands-on maintenance of equipment. Conducting training and maintaining training records is essential for ensuring that all personnel are aware of safety procedures and practices. Assisting in mishap investigations is important in understanding the causes of incidents and implementing preventative measures. Similarly, representing the division at the command safety committee allows the safety petty officer to advocate for safety concerns and improvements.

Performing routine maintenance on safety equipment, however, typically falls under the purview of specific technical personnel or maintenance teams, rather than the safety officer who focuses more on training and policy enforcement. Thus, the correct answer reflects that routine maintenance is not a direct responsibility of the division safety petty officer.
