Break a CFL? Don't panic.
Lisa Sharkey had a bit in the day before today's Huffington Post in which she defined her panic over a broken compact fluorescent light bulb in her home. She then listed a chain of clean up methods that would simplest have been written via a non-public damage attorney. Sheesh. Calm down already!
All fluorescent mild bulbs incorporate elemental mercury. That consists of the lengthy, thin ones in places of work and colleges. Elemental mercury is a evidently-going on heavy metallic it is also a neurotoxin in excessive enough doses. Elemental mercury is a liquid at room temperature and it evaporates right into a gas effortlessly. That gasoline glows when energy passes through it. Hence its use in light bulbs. Mercury has an extended list of realistic uses and is determined in the entirety from Mercurochrome to mascara. High concentrations of elemental mercury are more unfavorable as a fuel than as a stable, so there are some sensible precautions you may need to take need to you damage one of these bulbs.
But permit's get a touch perspective first and do a little math.
Let's say you wreck a CFL containing five milligrams of mercury in your toddler?S bedroom. Further, let's assume that bedroom has a extent of 25 cubic meters (it's a medium-sized bed room). For the sake of instance, allow's count on that the entire 5 milligrams of mercury inside the bulb vaporizes straight away. This would result in an airborn concentration of 0.2 milligrams in keeping with cubic meter. This attention will decrease with time, as air inside the room leaves and is replaced with the aid of air from out of doors or from a exclusive room. So even in case you do nothing, the concentrations of mercury inside the room will in all likelihood technique zero after about an hour or so.
Under those quite conservative assumptions, this degree and period of mercury publicity isn't risky, considering that it is lower than the US Occupational Safety and Health Administration (OSHA) fashionable of zero.05 milligrams in keeping with cubic meter of metal mercury vapor averaged over 8 hours.
To equate the extent of exposure in our damaged bulb scenario with OSHA's eight-hour widespread Imagine the on the spot level of mercury in the room straight away after the bulb broke to be zero.2 milligrams of mercury consistent with cubic meter. If we count on the air inside the room changes every hour, then the eight-hour average attention would be .Half milligrams in keeping with cubic meter.
See? No want to panic. While I wouldn't name it innocent precisely, it's no longer some thing you need to name a Hazmat crew over.
So, within the event which you spoil a CFL, open a window to hurry up the dispersal of the mercury vapor. If it makes you experience higher, leave the room for a 1/2 an hour. Then come again and clean up the broken glass.
