Electrical Equipment & Asbestos Exposure
Electricians may remember the panel, switchgear room, motor control center, cable work or maintenance task even when the insulating material or component name is forgotten. That is enough to begin a focused exposure investigation.
For electricians, the maintenance task is often the key memory
Historically, asbestos appeared in some electrical and heat-resistant components and in materials used around electrical systems. Investigation should focus on what equipment was opened, cleaned, repaired or replaced—not simply whether electrical equipment was present in a building.
Equipment memories
Start with the system or component you serviced.
- Switchgear and breaker equipment
- Motor controls, starters and contactors
- Panels, terminal equipment and disconnects
- Motors, generators and industrial electrical systems
Hands-on tasks
Specific maintenance activity can identify likely material disturbance.
- Opening and cleaning equipment
- Replacing worn insulating or arc-control parts
- Cutting, stripping, splicing or terminating cable
- Drilling, filing or fitting electrical components
Work environment
The location can reveal overlapping exposures.
- Powerhouses and substations
- Factories and industrial plants
- Commercial and institutional buildings
- Rail, transit and utility facilities
Nearby-trade exposure
Electrical work often occurred beside other dusty maintenance.
- Pipe and boiler insulation work
- Drywall and construction activity
- Mechanical equipment overhaul
- Cleanup after shutdowns or renovations
Details worth writing down now
- What switchgear, breakers, controls or panels did you service?
- Did you open, clean, file, drill or replace internal components?
- What wire or cable work did you perform?
- Were you in substations, powerhouses or industrial electrical rooms?
- What other trades worked beside you?
- What employer, jobsite and approximate years do you remember?
Do not worry if some answers are incomplete. Work histories can be developed from partial memories, coworkers, employment records, jobsite information and other evidence.
