Introduction
Asbestos, a name that has become synonymous with hazard and danger, is a group of naturally occurring minerals known for their exceptional insulating and fire-resistant properties. These attributes led to its wide usage in various industries, particularly construction, for several centuries. However, today asbestos is recognized globally as a health hazard, and its use has been banned in over 60 countries. Long-term exposure to asbestos fibers can lead to severe health complications, including asbestosis, lung cancer, and mesothelioma.
History
The history of asbestos dates back to around 4000 years ago, with the Ancient Egyptians being among the first to harness its properties. They utilized asbestos for a range of purposes, from construction to the creation of durable cloths. Over time, the industrial revolution amplified its usage due to its excellent insulating and fire-resistant properties. However, it was not until the 20th century that the health implications of asbestos began to surface, leading to its eventual ban in many countries.
Ban on Asbestos
The mounting evidence of the health risks associated with asbestos led to significant action against its use in the 1970s and 1980s. In November 1973, the U.S Department of Labor banned its use in new construction projects, particularly as an ingredient in insulation materials. This decision was due to the growing recognition of the health risks associated with asbestos exposure. As more countries became aware of these risks, similar bans were implemented worldwide.
Health Risks
The health implications of asbestos are grave and far-reaching. Exposure to asbestos fibers, particularly when they are inhaled, can lead to a variety of health conditions. These include asbestosis, a chronic lung disease caused by the inhalation of asbestos fibers; lung cancer; and mesothelioma, a rare form of cancer that affects the lining of the lungs and abdomen. The U.S. Environmental Protection Agency (EPA) released a report in 1989 that estimated asbestos to be responsible for an alarming 10,000 deaths per year in the U.S. alone, or 15% of all cancer deaths. Recognizing these devastating health effects, India in 1991 also implemented a comprehensive ban on the use of asbestos in any products requiring fireproofing or insulation.
Common Sources
Asbestos was used in a multitude of products, particularly in construction materials. Consequently, many older buildings and homes can still contain asbestos. Common sources of asbestos include:
- Insulation batting
- Ceiling tiles
- Plasterboards and wallboards
- Floor tiles
- Drywall joint compound
- Pipe covering compounds
Many items produced before 1980 are likely to contain asbestos. Hence, it is crucial to test these items if you suspect they might contain this hazardous substance. This is particularly important when buying an older home or planning renovations on a property that may contain asbestos materials.
