Chemical energy: trigger questions and direct controls

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

Corrosive, toxic, flammable and reactive substances cause harm by contact, inhalation and reaction. Quantity, concentration and incompatibility decide the exposure, and none of them belong in a simple energy formula.

Trigger questions

Are the substances in use identified, with current safety data available?
Could incompatible substances come into contact through mixing, spills or shared equipment?
Is ventilation adequate for the substance and the space?
Are exposure controls specific to this chemical, not generic PPE?
Are spill response and first aid measures available at the work location?

Controls to verify

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

Substance-specific PPE is in use.
Incompatible substances are physically segregated.
Eyewash and spill response are available at the point of work.
Lines and vessels are proven empty before connections are broken.

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.
