Control measure
Safe system of work: Pressure systems and equipment
Control measure knowledge
Operators should be made aware of the presence of responders before personnel enter the hazard area.
Isolating power supplies
It may be necessary to isolate power supplies to pressure systems and equipment, especially if there is a potential hazard to personnel or other emergency responders. Where possible, advice or assistance should be requested from the responsible person; they may be able to isolate the power supplies for the pressure system.
Depressurising systems
Safety valves may be fitted to the equipment to relieve excess pressure; it may be necessary to use these to depressurise equipment to reduce the risk of a pressurised system bursting.
Where possible, advice or assistance should be requested from the responsible person; they may be able to depressurise the system.
Strategic actions
- Ensure that information about the type, quantity and location of pressurised systems is included in Site-Specific Risk Information (SSRI) if appropriate, along with procedures for isolating power supplies
Tactical actions
Consider requesting advice or assistance from the responsible person to isolate power supplies or depressurise the system considering any consequences of this action
- Consider requesting that the use of pressurised systems is restricted or prohibited
Consider isolating power supplies for the pressure system or equipment considering any consequences of isolation
Ensure that operators are made aware of the presence of personnel and other responders
