1. Depending on the results of the initial risk assessment, and in order to ensure compliance with the relevant limit value as laid down in Article 8, the measurement of asbestos fibres in the air at the place of work shall be carried out at regular intervals during specific operational phases.

2. Sampling shall reflect the personal exposure of the worker to dust arising from asbestos or materials containing asbestos.

3. Sampling shall be carried out after consultation of the workers and/or their representatives within the undertaking or establishment.

4. Sampling shall be carried out by suitably qualified personnel. The samples taken shall be subsequently analysed, in accordance with paragraph 6, in laboratories equipped for fibre counting.

5. The duration of sampling shall be such that representative exposure can be established for an 8-hour reference period (one shift) by means of measurements or time-weighted calculations.

6. Fibre counting shall be carried out by electron microscopy or by any alternative method that provides equivalent or more accurate results.

7. For the purpose of measuring asbestos fibres in the air, as referred to in paragraph 1, only fibres with a length of more than 5 micrometres, a breadth of less than 3 micrometres and a length/breadth ratio greater than 3:1 shall be taken into consideration. Notwithstanding the first subparagraph of this paragraph, fibres with a breadth of less than 0,2 micrometres shall also be taken into consideration for the purposes of Article 8(2), point (a), from 21 December 2029.
