Evaluate airflow and filtering systems, clean frequently to prevent buildup, and utilize all appropriate occupational health and safety procedures to prevent contamination of the facility and contamination of the worker.
Electrical facilities maintenance includes electrical systems, fire alarms, security systems, and a variety of electrical equipment. Utilize all current requirements for the disposal of hazardous wastes since hazardous waste may be generated from the use and disposal of electrical equipment components such as: thermostats, switches, level gauges, and relays that contain mercury; telephone panels, fire panels, motion detectors, and emergency lights which may use sealed lead-acid or lead- cadmium batteries; other batteries that may contain mercury, cadmium, silver, or lithium; fluorescent lights containing neon, mercury vapor, high-pressure sodium, and metal halide light bulbs which may contain mercury; and old electrical equipment manufactured before July 1979 which may contain PCBs or PCB-contaminated items.
