Final answer:
Support equipment should be removed at least 50 feet away from explosives sites before refueling to ensure safety.
Step-by-step explanation:
In order to ensure safety when refueling support equipment near explosives sites, it is recommended to be at least 50 feet away. This distance is necessary to minimize the risk of ignition or explosion due to sparks or heat generated during the refueling process. Removing support equipment to such a distance helps to create a safe zone and prevent accidental incidents.
For example, when refueling a gas-powered generator near an explosives site, it is crucial to ensure that the support equipment is at least 50 feet away, such as parked outside the designated area or in a safe storage location.
By following the recommended safety guidelines, the risk associated with refueling support equipment near explosives sites can be significantly reduced.
