Site Plans with Atmosphere Zones & Controlled Zones

Requirements of a site plan.

Site plans must be maintained and accurately show the physical position, relative to the legal boundaries of the site of:

 all hazardous substance locations that contain classes

2, 3, or 4 substances; and

 all hazard atmosphere zones within the workplace where classes 2 or 3 substances are located.

 all controlled zones within the work place

Reg 10.26(4)(b) Health & Safety at Work (Hazardous Substances) Regulations 2017


Site Plans are required to be drawn to specific standards.

The Code of Practice, (HSNOCOP 37-2), requires hazard atmosphere zones to be delineated in accordance with the standard AS/NZS 60079.10:2009.

For professionally drawn site plans that include hazard zones, control zones and assistance in electrical certification, I suggest you discuss your needs with either of the following:
