TRACEABLE METHODS

Know what is behind the result.

Each resource has its own method, input requirements and limitations. Follow the references on the resource page for the source that applies to your calculation.

Source use

Where a recognised method is used, the page links regulator, public health or manufacturer material. A reference to a body does not mean that body has reviewed or endorsed this implementation. Plain arithmetic tools and assessor-input worksheets are labelled separately.

Regional and equipment limits

A US incident-rate method is not a worldwide reporting requirement. A GB noise action value is not a universal legal threshold. Manufacturer-specific fall or lifting inputs must fit the actual system. Always read the scope before entering values.

Resource method notes

Checks and corrections

The beta includes worked-example and calculation checks. Professional and site-specific review is still required before operational reliance. To report a discrepancy, send a correction with the inputs, units, expected outcome and source.
