Hierarchy of controls

The best solution to managing hazards is elimination followed in order by the other controls cascading from left to right.

Get rid of the hazard.

Replace the hazard with something safer – eg replace solvent-based paints with water-based ones.

Limit access by workers – eg install a guard to prevent access to moving parts of machinery.

Install engineering solutions to limit a worker’s exposure to, or difficulty with, the hazard – eg use springs to self-close gates.

Alert all workers and visitors to the danger of the hazard with appropriate signage and follow safe work procedures, provide appropriate information and training and supervision.

If the risk remains, use appropriate personal protective equipment (PPE) to minimise the potential for injury – eg ear muffs, face masks, gloves, hard hats.
