Description

The present invention relates to protective clothing for asbestos removal work with a blower attachment part.

Asbestos was widely used in building materials and friction materials in the latter half of the 20th century. However, most developed countries now ban the use of asbestos because it causes serious health problems such as lung cancer and mesothelioma after a long incubation period for workers and the general public who inhale it.

However, as existing buildings will continue to be demolished until the mid-21st century, there will be no asbestos exposure prevention measures for workers engaged in work such as demolition of asbestos-containing buildings, and measures to prevent asbestos scattering and leakage into the general environment. This has become an extremely important and urgent issue.

For this reason, the Ministry of Health, Labor and Welfare and the Ministry of the Environment have created the ``Comprehensive Manual for Preventing Asbestos Exposure and Asbestos Scattering and Leakage in Demolition of Buildings, etc.'', which provides guidelines for asbestos removal work.
