How many fire extinguishers must be available for refueling operations?

For refueling operations, the requirement for having two fire extinguishers ensures an adequate level of safety and preparedness in case of a fire emergency. This is based on industry standards and safety regulations, which dictate that at least two fire extinguishers should be readily accessible to effectively manage a fire situation.

Having two extinguishers allows for one to be used in case of an emergency while the other is available for backup or can be used to protect personnel evacuating the area. It also enables a more robust response if a fire were to occur during the potentially hazardous activity of refueling. Refueling involves flammable materials, and the presence of two extinguishers enhances the safety measures in place, providing a greater chance of quickly dealing with any fire that may arise.

Single extinguishers may not suffice, as they could potentially be rendered ineffective or inaccessible during an emergency, either due to being used or because of proximity issues during a fire incident. Having more than one, particularly two, allows for additional operational safety and quick access from multiple points around the refueling area.
