The hazards of working with electricity, natural gas, treatment chemicals, and wastes can be substantial, but generally are avoided by following rigorous safety procedures. Protective gear such as rubber gloves with long sleeves, nonsparking maintenance equipment, and body suits with breathing devices designed to filter out any harmful fumes are mandatory for work in dangerous environs. Employees also undergo extensive training on working with hazardous materials and utility company safety measures.

In 2002, the utilities industry reported 5.0 cases of work-related injury or illness per 100 full-time workers, compared with an average of 5.3 cases for all private industries, and 7.2 cases for manufacturing industries.
