Electricians have been exposed to asbestos on the job up until the early 1980s, when stricter safety regulations came into effect. There are multiple ways in which asbestos exposure could have occurred. By removing, cutting or drilling through asbestos-containing building materials - such as wallboards and tiles - to install or re-route wiring in a house, toxic fibers would be released into the air. Insulation film and paper, as well as wiring insulation, were also products commonly used by electricians, all of which were manufactured with asbestos. Moreover, asbestos was present in products such as electric boards, too, which electricians would often have to repair.
