Hazardous Vapors!
If large numbers of UV bulbs are broken, an appropriate respirator should be considered to
prevent inhalation of mercury vapors. Failure to use a respirator could result in death or serious
injury.

Bulbs are fragile and can be easily broken. Always use gloves and eye protection when handling
these bulbs. Failure to handle bulbs properly may result in minor to moderate injury. Refer to the
MSDS sheet from the bulb manufacturer for additional safety information.
6. Always use cloth gloves and suitable eye protection when cleaning or replacing these bulbs.
Bulbs may break if dropped or handled improperly.
Disposal of Bulbs
UV bulbs, like fluorescent bulbs, contain mercury, which is a regulated hazardous waste. The
disposal requirements for hazardous wastes are determined by local, state and federal guidelines.
Check all regulations before disposing of bulbs to assure you have met all requirements.
Refer to the MSDS sheet from the bulb manufacturer for additional disposal, handling and safety
information.
After replacing bulbs, close and latch all unit panels and reenergize power to the lights.
