When working with other businesses on the same job...

Under the previous H&S regulations there was a connection between who was paying for a service and responsibility for H&S.

Under our current Act it’s more about influence. (or control over a situation)

So if you are working with other businesses on a worksite, ask the question: “What influence does my firm, or my workers, have over safety issues”.

WorkSafe put it this way:

The extent of your duty to manage risk depends on the ability of your business to influence and control the matter. Where there are overlapping duties, the extent of each business's responsibility to carry out their duties will most likely be different. This will depend on what ability your business has to influence and control the health and safety matter (ie the more influence and control your business has over a health and safety matter, the more responsibility you are likely to have).
