How often should I get my anchor points inspected?

There is a common misconception in the industry that arranging an
annual inspection of your Anchor Points keeps them ‘in-date’ and usable year-round.
This concept is based on Australian Standard AS/NZS 1891.4:2009, however Standards are guidelines only - they cannot be enforced unless a Regulation requires a particular Standard to be followed.
Note the Australian Legislative Framework diagram below:
So what does Legislation actually mandate?
Most Australian states and territories, including Western Australia, actually require 6-monthly inspections. WA Occupational Safety and Health Regulations 1996:
Regulation 3.53 states:
My Anchor Points are rarely used, so can I just get them inspected once a year?
Arranging an annual inspection is fine, but there is nowhere in Legislation that then permits that Anchor Point to be used more than six months after inspection. The law affirms that if it has been longer than six months since
any Anchor Point has been inspected – then it should be considered off-limits, until an inspection has taken place.
To comply with WA Regulations then, most property managers implement a 6-monthly inspection regime to ensure their Anchor Points are kept ‘in-date’ and usable year-round. Doing this ensures safe access to a roof can be quickly achieved in the case of an emergency (eg roof leaks, storm damage, blocked gutters etc), without the need to arrange a formal inspection first.
