Incandescent light bulbs have been around since the beginning of light bulbs. The makeup of an incandescent bulb is simple, there is a frosted bulb that illuminates because a carbon filament coil heats up and causes the frosted bulb to glow. Incandescent light bulbs have been used since they were invented 130 years ago.
1. Heat Dangers
The heat that is generated from even the lowest watt of incandescent light bulb is extreme. If a light bulb burns out you should wait a few minutes to change it out because you can burn your fingers. The current that runs through the coils inside the bulb generates heat that is transferred to the glass bulb because glass is a good conductor of heat.
The glass that is used to make incandescent light bulbs is very thin, This helps the light to shine clearly through the bulb, whether it is a frosted bulb or a clear or colored bulb. Because of this it is extremely fragile and a very slight bump can cause the light bulb to break. The small shards of glass that fall from the shattered bulb can get into an eye, or be stepped on and difficult to remove. Additionally, if the light bulb breaks inside the socket it is dangerous to try to remove the light bulb from the fixture. A good method to remove such a bulb is to use a potato, push it hard onto the broken end of the bulb that is in the fixture and turn the bulb out of the socket.
3. Exploding or Bursting Light Bulb
There is air inside of a light bulb. When the air is very cold inside a light bulb the heat that comes from the copper filament can cause an adverse reaction on the air inside the bulb causing it to expand too rapidly and thus burst the glass of the bulb. If someone is near the bursting bulb they can be hit by the glass shrapnel.
4. Eyesight Dangers
Lights are very bad for the eyesight. Staring into an incandescent light bulb can cause severe eye damage including cataracts. It is necessary to ensure that your bulbs are covered with a shade or a covering to help mute and filter the bright light of the bulb. The light of even a 40 or 25 watt light bulb can be enough to harm your eyesight. Do not stare directly at an incandescent light bulb.
5. Environmental Dangers
An incandescent light bulb is not chemically dangerous and is authorized to be put right into the trash and then hauled away with your local garbage truck. Once the bulb gets to the landfill it becomes part of the huge waste problem occurring in the country.
