Can I use a regular industrial vacuum for asbestos dust?

No. Only a Class H (HEPA) industrial vacuum cleaner suitable for hazardous dust must be used, as specified in Clause 6.2.2.

What is the most critical safety measure when cleaning asbestos?

Using appropriate Respiratory Protective Equipment (RPE) and employing wet methods to prevent fibre inhalation are the most critical safety measures (Clause 5 & 6).

How should I dispose of cloths used for cleaning asbestos dust?

They should be treated as asbestos waste. Place them in a sealed, impermeable bag clearly labelled as 'Asbestos Hazard' and dispose of them at an authorized hazardous waste site (Clause 8).

Is air monitoring required during cleaning?

Yes, air monitoring is recommended to ensure that the control measures are effective and exposure limits are not exceeded (Clause 4.1.3).

Practical Notes

Dry sweeping or using compressed air for cleaning is strictly prohibited as it disperses asbestos fibres into the air.

Always use wet methods (e.g., damp cloths, water sprays) to suppress dust when handling or cleaning asbestos-containing materials.

Ensure all waste is double-bagged in clearly labelled, heavy-duty polythene bags for disposal as specified hazardous waste.
