The short answer

For your subcontractor crews, use this guidance with the current work phase, trade responsibilities and approved procedures in view. Keep your safety manager involved in record reviews and follow-up. This guidance supports record keeping and coordination, not technical authorization to carry out the work.

A hazard is anything with the potential to cause harm, such as a trailing cable, a chemical or an unguarded edge. Risk combines how likely it is that harm happens and how bad it would be.

A hypothetical example

A forklift is a hazard. In a designated construction delivery route with a trained driver, the risk of someone being struck may be low. In a shared walkway at shift change, the same forklift carries a much higher risk.

Why the difference matters

You cannot always remove hazards, but you can reduce risk.

  • Remove or replace the hazard where possible
  • Separate people from it
  • Change how the work is done
  • Use protective equipment as the last layer

The takeaway

Spot the hazard, judge the risk, and reduce it starting with the most effective control.
