Emergency plans @Jane is this a specific emergency response plan for your business, or have you strayed into a general disaster plan? (i don't know what is relevant for your business either)
@Riki Brown Section 14 of the Regs is reasonably prescriptive about it being relevant to the nature of your businesses forseeable emergencies that you have control or influence over, especially when read in the context of Sections 13 and 15. Worksafe's website information is very much specific hazard based = flammable materials, hazardous substances, fall from heights, excavations and trenches, risk of drowning, engulfment etc.....
We are a utility critical infrastructure, so our emergency management plans have to conform to the Civil Defence Emergency Management Act. We have do do all the things and much much more that are listed above.
Possibly so would essential services like farms, but a non-essentail retail business is likely to shut it's doors and ride out the storm (safer for people to stay at home, if they evacuate they are not coming to work anyway) - remember the questions during Covid levels about who be open and who should close???
