When evaluating safety on a job site, which compound might you encounter in some fluorescent fixtures?

• A. PCBs
• B. Sugar
• C. Alcohol
• D. Caffeine

Answer: (A)

Older fluorescent fixtures may contain PCBs in the ballast oil. PCBs (polychlorinated biphenyls) were used as dielectric and heat-transfer fluids in electrical equipment, including some fluorescent light ballasts, especially in older installations. They were prized for their stability and insulating properties, but they’re highly persistent in the environment and can pose serious health risks if released or inhaled as dust or fumes. On a job site, you’ll encounter PCBs when you’re working with older fixtures or ballast components. If a ballast is damaged, leaking, or being replaced, PCB-containing oil can contaminate surfaces and expose workers to hazardous materials. The safety approach is to treat older ballasts as potentially PCB-containing, de-energize the circuit, avoid opening or draining ballasts, and follow proper containment and disposal procedures. Use appropriate PPE, contain any spills, and arrange for hazardous-waste handling in line with local regulations and your site’s Environmental Health and Safety plan. Sugar, alcohol, and caffeine aren’t part of fluorescent fixture ballast systems, so they wouldn’t be encountered as components or hazards in this context.
