Complex stored energy: trigger questions and direct controls

This energy type is present. This tool does not calculate it.

Springs under load, suspended counterweights, tensioned cables, hydraulic accumulators and compressed components store energy in ways that are hard to see and easy to release by mistake.

Trigger questions

What is holding energy in this equipment right now?
Could removing a bolt, clamp or support release stored energy?
Has the stored energy been released or restrained before work starts?
Does the manufacturer procedure identify stored energy points?

Controls to verify

Ticks stay on this screen only. Nothing is saved or sent.

Stored energy is isolated before intervention.
Restraints are applied before fixings are released.
Manufacturer instructions for stored energy are followed.
Only competent persons dismantle energy-holding assemblies.

Some energy cannot be reduced to a simple field calculation. Where this energy is present in the work, treat it as high energy: the decision is made by presence, not arithmetic. Use the trigger questions and competent-person verification instead of a number.
