During what hours should a fire guard perform patrols according to best practices?

The correct response regarding the hours during which a fire guard should perform patrols aligns with best practices for fire safety management, particularly in construction environments. Fire guards are typically tasked with ensuring the safety and prevention of fire hazards, especially during heightened risks when construction activities are taking place and when no other safety personnel may be present.

Operational hours from 1600 (4:00 PM) to 2400 (midnight) cover the evening and nighttime periods, which often experience reduced visibility and potentially fewer onsite personnel. This time frame is critical since construction sites can have increased fire risks during these hours due to various factors such as ongoing work activities, heightened use of equipment, and possible absence of regular oversight. Therefore, having a fire guard patrol during these hours enhances fire safety measures by identifying and mitigating hazards promptly when the site may be less monitored.

In contrast, the other options present either earlier or inconsistent patrol hours that do not align with the peak times when fire hazards may arise. Therefore, the choice of 1600 to 2400 is considered best practice for fulfilling the responsibilities of a fire guard effectively.
