What must be done with the handle of the gauge during transportation?

Locking the handle of the gauge during transportation is crucial for maintaining safety and ensuring that the gauge is not accidentally activated or mishandled. This measure helps to prevent unauthorized use and protects individuals from potential exposure to radiation that could occur if the gauge were to be inadvertently switched on.

When the handle is locked, it secures the device and signifies that it is in a safe or off position, which is vital during transport. This practice ensures compliance with safety regulations and enhances the overall security of the nuclear gauge, thereby minimizing the risk of accidents and promoting safe handling procedures among personnel who work with or transport such equipment.
