Hierarchy of control measures

The hierarchy of control is a sequence of options which offer you a number of ways to approach the hazard control process. Here is a list, with typical examples. Work your way down the list, and implement the best measure possible for your situation.

Eliminate the hazard

• remove a noisy machine
• cease in-house operations of hazardous work.

If this is not practical, then:

Substitute the hazard with a lesser risk

• replace hazardous electrics with hydraulics
• purchase less hazardous machinery.

If this is not practical, then:

Isolate the hazard

• install guards, screens or enclosures
• install roll-over protection on mobile powered plant.

If this is not practical, then:

Use engineering controls

• redesign the task, to enable it to be carried out in a different way.

If this is not practical, then:

Use administrative controls

• set up entry permits to operate work systems
• install warning signs or danger tags.

If this is not practical, then:

Use personal protective equipment

• safety belts and harnesses, fall-arrest systems
• industrial safety gloves and footwear.
