So, what is the concentration of mercury vapor in ten cubic feet of air near where a single CFL device has been broken ? and where in the lamps does this 3 micrograms reside in the lamp, and why would it be in a vapor form at normal room temperatures? My observation of the broken lamps that I have seen is that there are quite large chunks and a few small slivers. I know that the slivers can be nasty and sharp, but clearly most of the white stuff is still in the glass. So where does all of this huge cloud of mercury vapor come from?
OF course it is best to avoid breaking the lamps, but this writeup seems to be intent on arousing hysteria and fomenting panic. If we went back to using candels for light the big hazard would be setting fires, which are probably a lot more dangerous.
I am not advocating stupidity, and I would never allow children to play with broken lights, but the whole tone of the article seems inappropriate for an intellectual publication such as Design News.
Interesting story, Todd. I would guess the packing that absorbs mercury costs quite a bit more than traditional packaging. I wonder whether this will affect its use. Unless there is a government mandate, it could be this packaging will not be widely utilized.
Earlier this year paralyzed IndyCar drive Sam Schmidt did the seemingly impossible -- opening the qualifying rounds at Indy by driving a modified Corvette C7 Stingray around the Indianapolis Motor Speedway.
Wearables are changing the way we see ourselves. With onboard sensors that have access to our bodies, we are starting to know our physical selves like never before, quantifying our activity, our heart rate, breathing, and even our muscle effort.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
