This standard provides guidelines for the safe handling of friction materials containing asbestos, such as brake linings and clutch facings. It outlines control measures, work practices, PPE requirements, and waste disposal procedures to minimize worker exposure to airborne asbestos fibres during manufacturing, installation, and maintenance.
Guidelines for safe use of products containing asbestos, Part 2: Friction materials
Quick Reference Values
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.
