Without limiting section 145, a rail safety officer exercising a power under this Part may bring to, onto, or into, rolling stock, a road vehicle or a place any equipment reasonably necessary for the examination or processing of things found at, on or in the rolling stock, road vehicle or place in order to determine whether they are things that may be seized.

The rail safety officer, or a person assisting the officer, may operate equipment already in or on the rolling stock or road vehicle, or at the place, to carry out the examination or processing of a thing found in or on the rolling stock or road vehicle, or at the place in order to determine whether it is a thing that may be seized, if the officer or person assisting believes on reasonable grounds that —

the equipment is suitable for the examination or the processing; and

the examination or processing can be carried out without damage to the equipment.
