| Asbestos is a substance that has been used for centuries. Its heat-resistant properties make it almost indestructible; due to this property, asbestos have been widely used in the construction industry, especially for pipe and boiler insulation. Before 1973, asbestos was sprayed onto different surfaces for fire protection purposes, but this practice was banned due to the hazardous nature of asbestos. Furthermore, it is no longer used for insulating pipes and boilers. However, asbestos can still be found in many older buildings. Those who work in construction, repair, demolition and renovations are at a greater risk of contracting asbestos-related diseases such as asbestosis, lung cancer, and mesothelioma. There is no safe level for exposure to asbestos. This course introduces the students to the hazards of asbestos in the workplace and provides information about the measures that must be taken in order to minimize the effects of exposure to asbestos. |
