Fluorescent light fixtures may contain which chemical?

• A. PCBs
• B. Mercury
• C. Lead
• D. Asbestos

Answer: (A)

Fluorescent fixtures with older magnetic ballasts can contain PCB oil in the ballast capacitors. PCBs were used because they act as stable dielectric fluids, but they’re highly toxic and persistent, so handling and disposal require proper procedures and regulatory compliance. Modern fixtures no longer use PCB-containing ballast components, which is why this is a safety-focused point to remember. The mercury you hear about is inside the lamp itself, not the ballast, so it’s a separate concern if a bulb breaks. Lead or asbestos aren’t the typical chemical associated with the ballast in fluorescent fixtures, though older components can have various hazardous materials in other parts.
