Fluorescent light bulbs contain a very small amount (4 to 6 mg) of mercury inside a glass tubing. In contrast, a thermometer contains about 500 mg of mercury.  No mercury is released into the environment when the bulb is in use, it is only released when the glass tubing is cracked or broken. If this happens, do not panic.  The first action is to have people and pets leave the room.  Air out the room for 5-10 minutes by opening a window or door to the outside, and shut off the central forced air heating or cooling system if it is in use.

Tips to prevent broken CFL’s:

• Allow a CFL bulb to cool before handling
• Screw or unscrew the CFL by holding the plastic or ceramic base, not the glass tubing.
• Screw in the CFL until snug, do not over-tighten.
• Never forcefully twist the glass tubing.
