What happens when a CFL bulb burns out?
A CFL bulb is different than an incandescent light bulb in the way it burns out. It will grow dimmer and dimmer as it reaches the end of its life. Some bulbs will simply stop working, while others will make a popping sound and then secrete a burning odor similar to an electrical smell.
Is it OK to leave a burnt out light bulb in the socket?
It is not safe to leave light bulb sockets empty. They pose an electrocution risk and a fire hazard because of high enough voltage to cause serious electrocution injury. Also, debris could get into the socket, get ignited, and start a fire, although this is an unlikely scenario.
Can a burned out light bulb cause a fire?
While the process of overheating is likely to cause a bulb to burn out, a bulb that has already burnt out will not cause a fire. The reason a burnt-out bulb cannot present a fire hazard is that it cannot consume electricity because the filament in the bulb is no longer intact.
Are CFL bulbs toxic when broken?
Is it harmful to be in the room where a CFL bulb has broken? The amount of mercury vapor that is released from one broken CFL bulb is not enough to make anyone sick. However, to avoid any exposure to mercury, we recommend that you leave the room for at least 15 minutes before cleaning up the broken bulb.
How long can you leave a CFL on?

What happens if you inhale mercury from a light bulb?
Mercury vapor is released when the bulb is broken. Inhaling mercury vapor is hazardous to your health. Breathing in mercury vapors may cause symptoms such as cough, fever, difculty breathing, nausea, vomiting, headaches, increased salivation and an acute metallic taste in the mouth.
How much mercury is in a CFL?
about four milligrams
Mercury, an essential part of CFLs, allows a bulb to be an efficient light source. On average, CFLs contain about four milligrams of mercury sealed within the glass tubing. By comparison, older thermometers contain about 500 milligrams of mercury – an amount equal to the mercury in over 100 CFLs.
Do CFL bulbs leak mercury?
Why is It Important to Clean Up a Broken CFL Properly? CFLs and the other light bulbs listed above contain a small amount of mercury sealed within the glass tubing. When a bulb breaks in your home, some of this mercury may be released as mercury vapor.
Why is mercury used in CFL bulbs?
Mercury is an essential element in the operation of fluorescent lighting; it allows the bulbs to be an efficient light source. Because CFLs contain trace amounts of mercury, it is important to educate yourself on proper use, recycling and disposal of these products.
