Asbestos mining still occurs in a few countries around the world, notably Russia, which is the largest producer, along with China and Kazakhstan. These countries have continued to mine and export asbestos, despite the well-documented health risks associated with its use and handling.
The timeline for banning asbestos in various countries varies significantly. Sweden was one of the first countries to ban asbestos, doing so in 1982. The United Kingdom fully banned all forms of asbestos in 1999, following a series of partial bans and increasing regulations starting from the 1980s. Similarly, the European Union banned all forms of asbestos in 2005. However, in the United States, asbestos is still not completely banned and is regulated under various federal laws and regulations.
In the United Kingdom, the use and management of asbestos are governed by several key pieces of legislation. The most significant are:
Control of Asbestos Regulations 2012: This is the primary legislation covering asbestos management in the UK. It sets out the duty to manage asbestos in non-domestic premises, the requirements for licensed work with asbestos, and the training and competencies required to undertake such work.
The Asbestos (Licensing) Regulations 1983 (as amended): This regulation provides specific guidelines for the licensing of asbestos removal work. It ensures that any work involving high-risk asbestos-containing materials is performed by trained and licensed professionals.
The Asbestos (Prohibitions) Regulations 1992 (as amended): This set of regulations formally bans the importation, supply, and use of all forms of asbestos, reinforcing earlier partial bans and controls.
These laws not only ban the use of asbestos but also impose strict regulations on how existing asbestos is managed. They require that asbestos-containing materials in buildings be identified and managed properly to ensure the safety of the occupants. This includes regular surveys, risk assessments, and, if necessary, safe removal and disposal of asbestos by licensed professionals. The Health and Safety Executive (HSE) is the regulatory body responsible for enforcing these regulations in the UK.
Asbestos floor tiles, a common feature in buildings constructed before the late 20th century, are known for their durability and fire-resistant properties. Typically made by combining asbestos fibers with various binding materials, these tiles were favored for their strength and heat resistance. However, despite their functional benefits, the presence of asbestos poses significant health risks. When these tiles are intact, the asbestos fibers are generally well-contained and pose minimal risk. The danger arises when the tiles are damaged, disturbed, or worn down, as this can release asbestos fibers into the air. Inhalation of these fibers has been linked to serious health conditions, including lung cancer, mesothelioma, and asbestosis. Consequently, the handling, removal, or disturbance of asbestos floor tiles requires professional expertise and adherence to strict safety protocols to mitigate the associated health risks.
