A health and safety briefing provided by the IET.
This guidance covers safe working procedures associated with equipment maintenance, cleaning, setting and operation, clearing blockages, and the associated need for electrical isolation. Where equipment uses additional sources of energy, such as hydraulics, pneumatics or mechanical drives, then isolation from these may also be necessary. Relevant maintenance activity includes that undertaken by electrically competent technicians. It could also be applicable to some operator tasks that do not present a risk of electric shock.
