Substitute, isolate and engineer are classed as being equally e ective. You will often need to use multiple controls on a single risk. Reassess
After putting controls in place, go back and reassess the level of risk. You may not always get your controls right the rst time. If the new level of risk is still too high, go back and put di erent controls in place, then reassess. Review and monitor
You’ll need to review your controls regularly to:
● ensure your planned controls are being
used
● checkthatcontrolsaree ective
● ensureyourrisklevelestimateiscorrect
● check in with workers if controls are
convenient and e ective
● monitorexposuretohealth
● identify new or di erent work activities
and risks
● consider if stronger controls are now
possible.
Remember to communicate
Once your risks are identified and your controls are in place, make sure you docu- ment them in an easy-to-understand manner in a hazard or risk register. This summary of site hazards and steps taken to control them should be available at all times for PCBUs to use when inducting new contractors, sub- contractors or visitors to a site.
A site job hazard and risk register can be downloaded from Site Safe’s website for free.
For more Site Safe o ers a free risk manage- ment guide designed speci cally for SMEs as well as a risk management course. To enrol or to download the guide, go to www.sitesafe.org.nz.

ELIMINATE
1
ELIMINATE THE HAZARD
— remove it completely from your workplace
If this isn't reasonably practicable, then ...
MINIMISE
2
SUBSTITUTE THE HAZARD
— (wholly or partly) with a safer alternative
Minimise the risk as far as reasonably practicable, by taking one or more
of these actions that is the most appropriate
ISOLATE THE HAZARD
— using physical barriers, time or distance
USE ENGINEERING CONTROLS
— adapt tools or equipment to reduce the risk
3
USE ADMINISTRATIVE CONTROLS
— develop methods of work, processes and procedures
If a risk then remains, you must minimise the remaining risk so far as reasonably practicable
4
USE PERSONAL PROTECTIVE EQUIPMENT (PPE)
— this is the last option if you have considered all the other options for your workplace
If a risk then remains, you must minimise the risk by using PPE
