TOHSS How to ... use the hierarchy of hazard controls Definition: A range of hazard control methods arranged in order of implementation preference.
In many cases a range of control methods
must be used to control hazards. This page lists various strategies to
be considered in order of preference. It is known as the hierarchy of
hazard controls. Whichever methods you use, remember that
in each case their effectiveness should be monitored regularly. The best way to eliminate the risk is to completely eliminate the hazard by removal from the workplace. In a research environment this is not usually a practical method. Therefore other controls must be considered. Example: reduce excessive photocopying by using email Substitution Once the hazard has been identified it may be possible to replace the activity, process or substance with a less hazardous one. Example: substitute telephone hand sets by head sets where telephone usage is high Engineering controls Example: use scissor trolleys to move equipment
between benches. Examples:
Personal Protective
Equipment Example: provide ear plugs or ear muffs
in noisy areas Reference
