What is the main objective of this code?

To provide a framework for controlling the release of and exposure to airborne asbestos fibres during the use of non-cement asbestos products.

What is the permissible exposure limit for asbestos fibres?

The time-weighted average (TWA) concentration over an 8-hour period should not exceed 0.1 fibres per millilitre (f/ml) of air.

What kind of personal protective equipment (PPE) is recommended?

Appropriate Respiratory Protective Equipment (RPE) with high-efficiency filters and disposable or non-woven fabric overalls are essential (Clause 5).

How should work areas be cleaned?

Cleaning should be done using a vacuum cleaner fitted with a High-Efficiency Particulate Air (HEPA) filter or by wet wiping. Dry sweeping is strictly prohibited (Clause 6).

This standard provides guidelines for the safe handling of asbestos cement products to minimize health risks from asbestos fiber inhalation. It covers best practices for storage, cutting, drilling, waste disposal, and the use of personal protective equipment (PPE). The primary focus is on dust suppression and control during all stages of work.

Permissible Exposure Limit (TWA for 8 hours)0.1 fibre/ml

Minimum air sampling volume400 litres

Maximum interval for static air monitoring6 months

Minimum frequency for medical examinationOnce every 12 months

Practical Notes

Always prioritize wet methods (e.g., using water or paste) when cutting or handling materials to suppress dust generation.

Ensure all waste is double-bagged in thick, labelled plastic bags and disposed of only at sites approved by the State Pollution Control Board.

Regular health check-ups for workers, including chest X-rays and lung function tests, are mandatory and crucial for early detection of asbestos-related diseases.
