Asbestos

Asbestos is a group of fibrous minerals once used widely in roofing sheets, insulation, brake linings, gaskets, and construction. India has not banned asbestos and it continues to be used in some industries and in old buildings. Long-term inhalation of asbestos fibres causes serious lung diseases — often decades after exposure.

Asbestos-related diseases

• Asbestosis — scarring (fibrosis) of the lungs from years of heavy exposure.
• Pleural plaques and thickening — changes in the lung lining; often symptom-free but a marker of exposure.
• Lung cancer — risk multiplies sharply if you also smoke.
• Mesothelioma — a cancer of the lining of the chest or abdomen, specifically linked to asbestos; appears 20–50 years after exposure, often in someone who forgot about a long-ago job.

Indian exposure scenarios

• Ship-breaking yards (notably Alang, Gujarat).
• Asbestos-cement roofing and pipe factories, construction workers removing old roofing.
• Vehicle brake- and clutch-lining repair (older formulations).
• Power plants, textile mills, thermal insulation work.
• Family members exposed by dusty clothes brought home — "take-home exposure".
• Old-building renovation — drilling, cutting, or breaking asbestos sheets releases fibres.

If you may have been exposed

• Tell every doctor — a careful occupational history is often missed.
• Annual health check with chest X-ray and lung function for exposed workers.
• Quit smoking — tobacco and asbestos together multiply lung-cancer risk dramatically.
• Flu and pneumococcal vaccines.
• Persistent cough, breathlessness, chest pain, weight loss — see a pulmonologist promptly.

Safety — if you work with it

• Wet methods of cutting/drilling to suppress dust.
• Properly fitted N95/N99 or higher-grade respirator — cloth masks don't protect.
• Change out of work clothes before coming home; wash them separately.
• Don't break or hose down old asbestos roofing — get professional removal.
• Know your legal rights — the Employee State Insurance scheme and labour laws cover occupational disease compensation; support from India's National Institute of Occupational Health is available.
