Lone working risks in maintenance


Sparking caused by electrical equipment like switches and motors may cause burning when in contact with live parts of the worker.

Electric shocks

Engineers and electricians dealing with electricity directly are exposed to electrical current and to risk of electric shocks causing pain or trauma.

Human errors

Complicated machinery involving disassembly and reassembly tasks outside routines, normal working hours and under time pressure increase the risk of human error and accident.
