This British Standard provides requirements for the control of hazardous energy whilst work is being carried out on machines.
This British Standard includes requirements for machinery in relation to electrical and mechanical hazards (i.e. moving parts, or parts that could move).
This British Standard also provides requirements for fixed equipment, such as motors and pumps fed via plug and socket-outlets.
This British Standard provides requirements and guidance to users of machinery on how to control hazardous energy on machines for safe working during all types of interaction.
Table I identifies five potential types of interaction on a machine, two for normal operation and three for maintenance, based on the risk profile of each interaction.
During normal operation of machines, fixed and interlocked guards are commonly provided to prevent access to dangerous parts, Maintenance tasks (which could include setting, process changeover, cleaning, unblocking as well as planned and unplanned maintenance)， might require alternative methods and controls to prevent injury, as the risks could well be different, requiring different risk reduction measures.
