The purpose
and procedures used in this survey are the same as for Type
1, except that representative samples and collected and analysed
for the presence of asbestos.
Samples
from each type of suspect ACM found are collected and analysed
to confirm or refute the surveyor's judgement.
If the
material sampled is found to contain asbestos other similar
homogeneous materials used in the same way in the building
can be strongly presumed to contain asbestos.
Less homogeneous
materials will require a greater number of samples.
The number
should be sufficient for the surveyor to make an assessment
of whether asbestos is or is not present.
Sampling
may take place simultaneously with the survey, or as in the
case of some larger surveys,
can be carried out as a separate exercise, after the Type
1 survey is completed.
