Sound energy: trigger questions and direct controls

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

Noise damages hearing gradually and permanently, and single impulse events such as blasts or bursts can injure instantly. Exposure builds with level and time, so a number in joules would say nothing useful here. Hearing protection is a last barrier, not a direct control.

Trigger questions

Which tools or plant on this task produce high noise, and for how long?
Can the noisy work be done with a quieter method or tool?
Can the noisy work be separated from other trades by distance, enclosure or scheduling?
Is impulse noise possible, such as cartridge tools, bursts or venting gas?
Is the noise area marked so others do not walk into it unprotected?

Controls to verify

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

Quieter methods and tools are used where they exist.
Noisy work is enclosed, separated or scheduled away from other trades.
The noise area is marked and briefed.
Hearing protection matched to the level is worn inside the marked area.

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.
