High hazard areas or compounds on-site still require the same housekeeping and cleaning as non-hazardous areas.  These areas pose a much higher risk for personnel working inside them and a greater liability to the ‘PCBU’ (Person in charge of the business unit) to provide a safe work environment.

What problems does this service solve?


If you have hazardous areas on your site, cleaning can be a challenge.  High hazard areas include:

  • high pathogen risk areas, such as spaces with dead carcasses, faeces or mould.
  • confined spaces, such as vessels, tanks, ducting, basements and ceilings
  • explosive atmospheres, such as milk powder stores and factories
  • toxic atmospheres from gas, fumes or chemicals, such as storm water sumps
  • high voltage areas, such as 1100KVA yards or salt-coated insulators
  • chemical storage areas, for example – where the liquid is a burn hazard for eyes, skin and clothes, or the fumes are a respiratory hazard.

Because these areas are hazardous, it is easy to just avoid cleaning them.  This is never a good idea – it always becomes a bigger problem somewhere along the way.  Weather-borne debris and pathogens have to be removed from these areas for safety and efficiency.
