Under what condition is it permissible to get on or off moving equipment?

Getting on or off moving equipment is primarily permitted in emergencies as a means of avoiding injury. This guideline is in place because the safety of the crew and personnel is the top priority in railroad operations. In situations where remaining on the moving equipment poses a risk to safety, climbing off quickly may be the only viable option to prevent harm.

This practice is strictly regulated, as the dangers associated with disembarking from moving equipment can lead to severe injuries. Therefore, this condition is explicitly allowed to ensure prompt action can be taken when an emergency arises, and no other safe alternatives are available.

The other scenarios, such as switching cars, adjusting equipment settings, or signaling personnel, involve tasks that can typically be planned and executed while the equipment is stationary. They are part of routine operations where safety measures and procedures dictate that personnel should only enter or exit moving equipment when absolutely necessary, as doing so in non-emergency situations can lead to accidents.
