Inspections & Monitoring

ACMs which are in good condition, sealed and/or repaired, and are unlikely to be disturbed, should be left in place and managed. This is a safer option than removal which will mean the ACMs are disturbed. Not only will this increase the risk of exposure of the in-situ site, potentially, if the material is mishandled in transit, there is a risk of further exposure as the material is removed from the location to its final depositing point.

If the ACMs are left in place they will have to be inspected regularly and their condition monitored. A useful way of monitoring would be to take photographs. These can be used to record and compare the condition of the ACMs over time.

The time period between monitoring will vary according to the type of ACM, its location, and the activities in the area concerned. The ACOP states (paragraph 104) that ACMs should be inspected at least every 6 - 12 months even if they are in good condition and are not going to be disturbed as it may be accidentally disturbed. ACMs is less than good condition should be inspected more frequently. Details of the checking system to be used to check the condition of the material in the plan must also be written down. ACMs in locations where there is a lot of activity will need more frequent monitoring, such as once a month.

Monitoring would involve a visual inspection, looking for signs of disturbance, scratches, broken edges, cracked or peeling paint and debris. Where deterioration has occurred, a recommendation on what remedial action to take would need to be made.

All inspections and subsequent actions should be recorded and updated with the information available and accessible to all relevant parties.
