The Occupational Safety and Health Administration (OSHA) estimates that 2.3 million construction workers (65 percent of the total construction work force) frequently work on scaffolds. Electrical contractors are no exception. A large portion of their work is performed on scaffolds and aerial lifts.
On the job, many electricians, linemen, wiremen and other construction-related workers will encounter or use a pneumatic-powered tool at some point. Pneumatic tools are powered by compressed air or compressed carbon dioxide (CO2) supplied by a small cylinder.
