According to NFPA regulations, what is prohibited while riding on the apparatus?

Riding on the outside of apparatus is expressly prohibited according to NFPA regulations, primarily to ensure the safety of personnel. This rule is in place because riding on the exterior of a fire truck or any emergency vehicle can significantly increase the risk of falls, injuries from collisions, or being struck by overhead objects. Firefighting operations can involve rapid movement and unpredictable circumstances, so regulations are designed to keep all personnel safely inside the vehicle and secured during transit.

By enforcing this prohibition, departments aim to minimize accidents and ensure that all firefighters are transported safely during emergencies, thus upholding the overall safety standards established by the National Fire Protection Association.
