Asbestos Identification Before Intrusive Maintenance
A Small Drill Hole Can Disturb Hidden Asbestos

Fixing one bracket can disturb material hidden behind a wall finish or ceiling panel. The size of the job does not establish whether asbestos is present, and appearance alone cannot confirm that a material is safe to drill. Before cutting, drilling or opening building fabric where asbestos may be present, check the asbestos information for the exact location and depth of the work. If that information is missing or incomplete, pause the job and get competent advice. Keeping the material undisturbed is the first practical step.
Controls to confirm
- Check the actual work area: review the current asbestos register and relevant survey with the person responsible for the building. Match the planned fixing, cable route or opening to the surveyed locations, including concealed layers. Treat inaccessible or excluded areas as potentially containing asbestos until assessed; do not turn a gap in the report into permission to drill.
- Resolve uncertainty before starting: have a competent person decide whether further investigation or a refurbishment survey is needed for the planned disturbance. Plan to avoid asbestos wherever possible. Any necessary asbestos work must have a risk assessment, task-specific controls and appropriately trained, competent personnel, with a licensed contractor where required by local rules. Awareness training alone does not qualify someone to work on asbestos.
- Stop if suspect material appears: cease work, keep others away and notify the supervisor or building manager. Do not break off a sample or sweep, vacuum or blow away suspect debris yourself. Follow the site's asbestos incident procedure and have competent specialists assess the area and arrange any necessary cleanup before authorizing a restart.
Today’s action
Before today's first intrusive maintenance task, walk the planned work location with the responsible person. Verify survey coverage and exclusions, and record who must resolve any uncertainty before tools are used.
