Electrical

Historically, asbestos was used for electrical wire insulation. It was used nearly everywhere: on ships, in airplanes, homes, and commercial buildings. There were numerous manufacturing companies and brands, including General Electric's Deltabeston brand which was named after the asbestos used in its cables and wires. Asbestos was also used in transformers and other electrical equipment. Electricians as well as anyone doing restoration could be exposed while replacing or upgrading equipment.
