摘要

A handheld device (12) used in a fuel supply environment where there is someone on duty. Power is supplied to the handheld device (12) by an intrinsically safe battery pack (22). The battery pack (22) is provided with an integrated current-limiting protective circuit (28). The protective circuit (28) ensures that energy generated in the form of spark or heat is maintained at a level lower than the minimum ignition energy of an explosive gas.
