F-02 Study Guide 2026

Red is the color for flammability hazard on the NFPA 704 diamond, located at the top of the diamond. A rating of 0 means the material will not burn, while a rating of 4 means it will rapidly vaporize and burn readily at normal temperatures.

A complete no-hazard entry includes start time, areas patrolled, completion time, and a clear notation that all areas were found free of hazards.

NFPA 10 requires that heavier extinguishers (over 40 lbs) have their carrying handle mounted no higher than 3.5 feet, while lighter units can be mounted up to 5 feet — the 5-foot rule applies to lighter units.

Heat and smoke rise, so the floor immediately above the fire is at the greatest risk and should be the second priority for evacuation.

Before beginning patrols, the incoming fireguard must review the previous log entries, receive a briefing on current system status and any open issues, and make their opening log entry.

The Fireguard should first investigate the source of the alarm to determine if there is an actual fire condition. This allows the Fireguard to provide accurate information to the fire department and building management. Premature evacuation or calling 911 without verification can waste resources.
