Asbestos Fire Blankets: Safety, Uses, and Modern Alternatives
Asbestos fire blankets were once common for fire protection but pose health risks. This article explains their historical use, safety concerns, proper handling, and safer modern alternatives. You'll learn how to identify asbestos blankets and protect yourself.
What Are Asbestos Fire Blankets?
Asbestos fire blankets are heat-resistant safety devices made with asbestos fibers woven into fabric. They were widely used in the 20th century to smother small fires or wrap around people during evacuations. The asbestos content made them extremely durable and heat-resistant.
How Asbestos Fire Blankets Work
These blankets work by cutting off oxygen supply to flames. When placed over a fire, they create a barrier that prevents air from fueling the flames. The asbestos fibers can withstand temperatures up to 1000°F (538°C) without burning or melting.
Health Risks of Asbestos Fire Blankets
While effective for fire protection, asbestos poses serious health dangers:
- When disturbed, asbestos fibers become airborne
- Inhaled fibers can cause lung diseases including cancer
- No safe exposure level exists
- Symptoms may take 10-50 years to appear
Many countries have banned asbestos products, but older blankets may still be in use.
