Asbestos Hazards
Asbestos is the generic term for a group of naturally occurring fibrous minerals with high tensile strength, flexibility, and resistance to thermal, chemical, and electrical conditions.
Understanding Asbestos
Asbestos that was once widely used in various industries for its heat resistance and insulating properties has significantly decreased. However, some products may still contain asbestos.
Asbestos-containing materials (ACM) may present a health risk if they are damaged, deteriorated, or disturbed, releasing asbestos fibers into the air.
- Asbestosis: This most common health risk associated with asbestosis and is caused by inhaling asbestos fibers leading to lung scarring, breathing difficulties, and persistent coughing. It often requires the victim to use oxygen.
- Lung Cancer: Long-term asbestos exposure significantly increases the risk of lung cancer, especially for smokers. Other areas may become cancerous including the throat, gastrointestinal tract, and kidneys.
- Mesothelioma: A rare and aggressive cancer that affects the lining of the lungs, abdomen, or heart. It is directly caused by inhaling asbestos fibers and can take decades to develop after exposure.
- Other Cancers: Asbestos exposure has also been linked to cancers of the larynx, ovary, and digestive system.
- Pleural Diseases: Conditions like pleural plaques and pleural effusions, which cause lung inflammation and breathing issues.
- Building Materials:
- Thermal insulation (pipe insulation, duct insulation, and loose-fill insulation)
- Vermiculite insulation
- Roofing materials (roof shingles, felts, and coatings)
- Siding and cementitious boards
- Ceiling tiles and acoustic panels
- Flooring materials (vinyl floor tiles, linoleum, and floor adhesives)
- Drywall joint compound
- Fireproofing materials
- Automotive Parts:
- Brake pads and linings
- Clutch facings
- Gaskets and seals
- Heat shields
- Hood liners
- Industrial Equipment:
- Boilers and steam pipes
- Thermal and electrical insulation
- Electrical wiring insulation
- Laboratory gloves and aprons
- Fireproof clothing and blankets
- Consumer Products:
- Hairdryers and other heat-resistant appliances
- Fireplace gloves and stove gaskets
- Potting soils and vermiculite products
It's important to note that the presence of asbestos in these products can vary depending on the manufacturer, production year, and region.
