Which of the following is true regarding adding fuel to equipment?

Adding fuel to equipment is a critical task that must be performed with safety in mind. Allowing the engine to cool before fueling is essential because a hot engine can pose a significant fire hazard. Gasoline and other fuels are highly flammable, and adding fuel to a hot engine increases the risk of fuel vapors igniting, leading to potentially dangerous situations such as explosions or fires.

In many operational protocols, it is standard practice to ensure that the equipment is turned off and has cooled sufficiently before refueling. This practice not only enhances safety but also helps to prevent fuel spillage, which can occur if the engine is still warm and the fuel expands. Thus, ensuring the engine is cool is a key point of safety during the fueling process.
