There are three types of survey:
Type 1 – Location & Assessment Survey
All materials which are not visually identifiable as
non-asbestos are presumed to contain asbestos.
No samples are taken.
Type 2 – Standard sampling, Identification &
Assessment Survey
(Sampling Survey)
This is HSE's preferred survey.
This survey positively identifies asbestos containing materials
(ACMs)
Representative samples are collected and analysed to confirm or
refute the Surveyor's judgement.
Type 3 – Full Access Sampling &
Identification Surveys. (Pre-demolition/Major Refurbishment
Survey)
This survey locates and describes all ACMs in the building
and may involve destructive inspection to gain access to all
areas. A full sampling programme is undertaken.
