If a bulb breaks, only 0.67 milligrams of mercury (one-third of 40 percent of 5 milligrams) might become airborne in the room during the first eight hours, and only a fraction of that would be breathed in. Then use index cards or other stiff paper to pick up the broken pieces of glass and any visible mercury.
Is it dangerous if a light bulb breaks?
Compact fluorescent light bulbs (CFLs) contain small amounts of mercury. A small percentage of this mercury can be released into the air if the bulbs are broken. Mercury also can be released into the environment if bulbs are not recycled properly. Mercury can cause poisoning in some circumstances.
What to do if you break a lightbulb?
One supply you won’t want is a vacuum—it can spread mercury powder and vapor. Sweep the broken bits of glass into the glass jar or sealable bag. Use sticky tape to collect any remaining fragments, then place the used tape in the glass jar or plastic bag. Place any items used to clean up the area in a trash bag.
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.
What does breaking a light bulb mean?

Can a light bulb explode?
If the lightbulb you are using has a greater wattage than your fixture’s limit, your light fixture may overheat, and the bulb may explode. Fortunately, you can usually find the recommended bulb wattage printed on the label of the light socket. When this happens, gas can leak out of the bulb, resulting in an explosion.
How much mercury is in a light bulb?
An average of 4 milligrams (mg) of mercury is in a CFL. A mercury thermometer may contain about 500 mg of mercury. About 500 mg to 700 mg or less of mercury is considered a small spill. Some CFLs may contain as little as 1.4 mg to 2.5 mg per light bulb.
What happens if you break halogen bulb?
Take immediate action if your halogen bulb shatters while in use: Prepare a fire extinguisher and have all people and pets leave the room. The glass fragments are extremely hot and may cause a fire if they come into contact with flammable materials (see References 3).
How long does mercury vapor stay in the air?
At room temperature, exposed elemental mercury can evaporate to become an invisible, odorless toxic vapor. This vapor has a very long life (up to one year) in the air.
How do you know if you have mercury in your body?
Symptoms of mercury poisoning. Symptoms of mercury poisoning depend on the form of the mercury that was the source of the exposure. Early symptoms of mercury poisoning can include a metallic taste in the mouth and numbness and tingling in the hands, feet and face.
What does mercury vapor smell like?
Mercury vapor is not irritating and has no odor, so people do not know when they are breathing it. Even the small amount of mercury from a broken thermometer can cause harm, especially to children, unless it is properly cleaned up and removed.

Why did my lightbulb explode?
The most common cause of light bulbs exploding is when the manufacturers of the light bulb do not put enough insulation at the base of the bulb. This will then cause the base to melt and the gas that is stored inside the light bulb leaks out. When this happens the pressure difference makes the light bulb explode.
Why do light bulbs explode when dropped?
Extreme temperatures that cause fragility in the bulb’s surface or a weak base that allows the delicate balance of gas inside the bulb to escape will cause incandescent bulbs to actually explode from time to time, just one of the reasons light bulbs are one of the 50 Deadliest Things in Your Home.

If you turn off a hot incandescent bulb (it has to be 300 watts or higher) and then spray cold water at it. It will thermal shock the glass and shatter. But no. They won’t just spontaneously explode for no reason.
What does mercury do to the human body?
Health effects of mercury exposure The inhalation of mercury vapour can produce harmful effects on the nervous, digestive and immune systems, lungs and kidneys, and may be fatal. The inorganic salts of mercury are corrosive to the skin, eyes and gastrointestinal tract, and may induce kidney toxicity if ingested.
How much mercury is toxic to humans?
For elemental mercury vapour, several studies show that long-term workplace exposures– at around 20 µg/m3 of air or higher – have subtle toxic effects on the central nervous system.
