Posted By Peter Spence In the new OHSAS 18001: clause 4.3.1 it specifies the hierarchy of risk control measures as (a) elimination, (b) substitution, (c)engineering controls, (d) signage / admin and (e) PPE. Surely (d) and (e) are the wrong way round? I have always worked to ERIC PD, i.e. Eliminate, Reduce (including substitute), Isolate, Control; then PPE, and Discipline / Documentation (including signage) and I believe this to be logical. The question is, "Is it safer to provide PPE or a sign?". For example, if someone is in danger of touching something hot, is it better to give them overalls and gloves or stick up a notice to say 'Don't touch'? If the danger is a fall from height, which provides the greater degree of protection a life line and harness or a sign saying 'Don't fall off'? I know that it is stated that PPE is the last resort. But I take this to mean that the first priority is to prevent / minimise physical contact with the hazard through ERIC and only then should you consider PPE. Signage and/or administrative controls (on their own) are the weakest form of control and provide no physical protection whatsoever and so must come last in the hierarchy. Does anyone else agree?

Posted By Tom Doyle Peter, I think Steve got it right. I have always thought the word "hierarchy" is a bit misleading as most often several layers of protection from the "hierarchy" will be required. In all cases the "Hierarchy of control measures" does nothing more than guide you down a decision making path hopefully resulting in a number of appropriate choices.
