is the white powder in light bulbs dangerous

Print Friendly, PDF & Email

Like I said earlier, mercury is a silver liquid, not a white powder. When the mixture is ignited, it burns extremely quickly producing a bright flash that can be captured on film. Since you have mercury drop inside, it could mix with phosphor. These items are light bulbs in various shapes, configurations, and designs. When a CFL is turned on, electricity causes the mercury vapour to produce short-wave ultraviolet (invisible) light, which then causes the phosphor to fluoresce and produce visible light. The energy efficiency of CFLs may be significant, but unlike traditional light bulbs, there is a hidden danger sealed inside each little bulb that requires special handling and disposal. When electricity enters a CFL, mercury and argon fumes inside the bulb produce invisible ultraviolet (UV) light. UV In Our Atmosphere. The white powder is a phosphor coating that is applied to the interior of the glass. Mercury – a potent, developmental neurotoxin that can damage the brain , liver, kidneys and central nervous system. The first incandescent lights to depart will be the 100-watt bulb next January 2012, followed by the 75-watt bulb in 2013 and the 60- and 40-watt bulbs in 2014. 3 Page EPA Guidelines for the proper disposal of broken fluorescent bulbs. An emphasis will be placed on more efficient LED light bulbs, which are brighter, use less energy and last longer. The white powder coating inside the glass tubing of a CFL contains a fluorescent coating. Flash powder is a composition of metallic fuel and an oxidizer such as chlorate. While generally considered safe, there are a few potential dangers that you need to consider when using halogen light bulbs… As far as I know, the white stuff is pretty harmless. These phosphors glow only when irradiated with UV rays which, If at all you manage to lay hands on , could end up harming your skin & organs. Yet how would that help you? 4. The phosphors help provide continuous, white light, rather than the sheer flickering of the fluorescent gas. Remove and throw away any clothing or bedding that came in direct contact with the broken glass or the powder inside the bulb. All contain a small fluorescent tube (either twisted or bent to shape), a plastic housing (containing an electronic circuit to start the lamp), and a threaded base for use in standard incandescent lamp sockets (or a pin base for use in a GU24 socket). How do CFLs work? Many people use halogen light bulbs freely throughout their homes. The energy efficiency of CFLs may be significant, but unlike traditional light bulbs, there is a hidden danger sealed inside each little bulb that requires special handling and disposal. Halogen light bulbs are among the most common types of light bulbs in the world today, and they do have several benefits. The white powder inside the bulb is a metallic compound called phosphor. On the other end, the atmosphere blocks most UVC rays and reduces the amount of UVB rays which reach the surface, while allowing UVA rays to filter through. 3.2. Our atmosphere blocks out harmful high-energy radiation like x-rays, gamma rays and most of the ultraviolet rays.The atmosphere also absorbs most of the infrared radiation which reaches the Earth from space.
