Asbestos control measures are the layers of protection that keep fibres out of the air and out of your lungs. No single measure does the whole job - they work together, with the most effective controls applied first and personal protection used only as a backstop.
This guide explains the control hierarchy and the practical measures every worker should recognise, from avoiding disturbance altogether through to PPE, RPE and decontamination. Awareness training covers the principles; this is the worker-friendly summary you can apply on site.
Key takeaways
- The control hierarchy puts eliminating disturbance first and PPE last.
- Safe systems of work follow the risk assessment and method statement.
- PPE and RPE are the last line of defence, not the first.
- Decontamination prevents fibres being carried off site and home.
- Controls only work if the asbestos register is checked and the plan is followed.
The hierarchy of control
Asbestos controls follow a clear order of priority:
- Eliminate - the best control is to avoid disturbing ACMs at all.
- Reduce - where some disturbance is unavoidable, minimise it and limit the number of people exposed.
- Control - use enclosures, damping down, and low-disturbance methods to keep fibres from spreading.
- Protect - use the correct PPE and RPE as the final layer.
Safe systems of work
Controls only work when they are planned and followed. That means working to the risk assessment and method statement, checking the asbestos register before starting, and stopping immediately if something unexpected appears. A safe system of work turns the control hierarchy into specific, practical steps for the job in front of you - see asbestos risk assessment.

PPE and RPE - the last line
Where exposure is possible, suitable respiratory protection (RPE) and disposable coveralls reduce the risk to the individual - but they are the last line of defence, not the first. PPE protects one person if everything else fails; it does nothing to stop fibres being released or spread. It must be the right type, correctly fitted and properly worn. The detail is in asbestos PPE awareness and PPE and RPE equipment.
Decontamination
Proper decontamination - careful removal and disposal of single-use coveralls, and personal washing where required - stops fibres being carried out of the work area on clothing, tools or skin. This protects not only other workers but also your own family at home. Skipping decontamination is how asbestos exposure has historically spread far beyond the people doing the work.
Frequently asked questions
What is the best asbestos control measure?
Not disturbing ACMs in the first place. Elimination sits at the top of the control hierarchy.
Is PPE enough on its own?
No - PPE and RPE are the last line of defence and must sit on top of avoiding and controlling disturbance.
Why does decontamination matter?
It prevents fibres being carried off site on clothing and harming others, including your family.
Who sets the control measures?
The employer and duty holder, through the risk assessment and method statement for the work.
What if the controls in the plan are not enough?
Stop work and raise it - if conditions differ from the assessment, the work should not continue until it is reviewed.
