Travel distances for portable extinguishers used to protect flammable liquids of appreciable depth shall not exceed ____ ft.

The guidelines set forth in NFPA 10 indicate that travel distances for portable extinguishers to protect against flammable liquids with appreciable depth should not exceed 50 feet. This is based on the understanding that flammable liquids present a significant hazard, and timely access to extinguishers is critical in emergency situations to mitigate the risk of a fire spreading.

By ensuring that extinguishers are located within 50 feet, it facilitates a quick response, helping to control or extinguish a fire before it escalates. This distance is considered to provide an adequate level of safety while ensuring that personnel can efficiently reach the extinguisher without encountering obstacles or delays, reducing the potential harm and damage associated with flammable liquid fires.

It is essential for fire safety plans to adhere to these standards, allowing for effective fire protection strategies in environments where such liquids are present.
