Type 2 MDHS100 Asbestos Surveys (Sampling Survey)

The purpose and procedures used in this survey are the same as for Type 1, except that representative samples are 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 complete.

We always recommend Type 2 surveys as the additional cost of representative sampling means the dutyholder has a definitive report on all accessible asbestos containing materials.

This means the non asbestos materials determined from laboratory analysis can be eliminated from the management plan, reducing the cost of future management arrangements.
