California Classes LED Component Gallium Arsenide a Carcinogen

Reader LM741N, pointing to a report released this month by California's Office of Environmental Health Hazard Assessment, writes "Gallium Arsenide has now been listed as a carcinogen. Given the increasing usage of gallium arsenide, the main constituent in LEDs, and their recent championing as more efficient light sources in recent news stories and Slashdot, there may be significant environmental concerns as related to their disposal. Morover, workers in industries using the substance may be at risk of cancer as well."

    I guess I will have to stop eating LEDs, at least while in California.

    This is what happens when you have nanny state liberals in office. Let California be a lesson to the remaining 49 on how *NOT* to run a state.

    Did you forget to back that up with some compelling statistics you're saving for later? Let's compare housing values in silicon valley vs. detroit to see if you're right.

    Sign blindness is more of a real problem than the tiny amount of Gallium in LEDs. If you want to protect people, you can't deluge them with constant warnings. They eventually become sign blind and begin ignoring, or worse mocking warning labels. According to the labels, every can of paint in the hardware store causes cancer in California. But what I don't know is if paint A is going to make me infertile the moment I look at it, or if paint B is just a problem if I drink 5 gallons of it. The labels don't have any kind of granularity.

    A color coded system might do consumers well. No color==mostly OK. Green==Don't eat a bunch of this, it's not good for you. Yellow==Take care when using this, ventilation is a good idea and long term exposure is probably going to hurt you. Red==For the love of all that is holly, wear a respirator or leave it for the pros. Black==if you are reading this, you're already dead.

    California needs to remember that poison is in the portion. EVERYTHING is poisons in the right quantity. A warning label can be useful, when not slapped on every surface that it can physically bond to.

    Warning! This cliff is known to the state of California to cause plummeting, falling and smassing of bones. Gravity in effect at edge of cliff face! Short term exposure to gravity can cause serious injury.

    California has always been on path to economic self-destruction

    Which is why it has consistently had the strongest economy in the nation?

    As a life-long resident of California, I can guarantee that the success of the economy is in spite of the state government, not because of it.

    Well, its a free country, so feel free to not read any warning you like. But I like knowing that the power cable on my blender contains lead and that I should wash my hands after plugging it in and before touching food. I like knowing which products at Home Depot are more likely to cause respiratory problems. And yes, if a building I worked in contained excessive levels of some toxin, I would like to know about it.

    You don't get that kind of information though. You get a generic Proposition 95 warning sign that basically says "something sold, kept, or used on these premises has been deemed a cancer risk by borderline hypochondriac bureaucrats at the state level." It's no fucking use at all.

    Truly, a downtrodden people, crying out for the better way of life enjoyed by their fellow men in Mississippi.

    The right-wing anarcho-capitalist nutjobs HATE it that "liberal" states tend to be far more economically prosperous than the "conservative" anti-environment, anti-union states. It kills them.

    Since when is it a bad thing to notify consumers that the products they're buying and using may pose a health risk?

    Since doing so excessively will trivialize the risk.

    Imagine if instead of severe thunderstorm and tornado warnings, the national weather service issued "wet weather" warnings any time it wasn't sunny. You couldn't tell the difference between a summer shower and a hurricane, and since summer showers are much more common you wouldn't realize today's warning meant 80mph winds until it was too late.

    If you are going to do warning labels for things that aren't a significant risk, you should at least put a "danger level" on them. We could have categories like for tornadoes:

    Instead of the Enhanced Fujita Scale, we'll have the Enhanced California Scale:

    EC0 - You might get cancer. But 40 million other Californians won't.
    EC1 - 1 in a million lifetime cancer risk from a single exposure
    EC2 - 1 in 10,000 lifetime cancer risk from a single exposure
    EC3 - 1 in 100 lifetime cancer risk from a single exposure
    EC4 - If you touch it and live another 50 years, you'll get cancer
    EC5 - You'll be lucky to be alive a year from now
    EC6 - You'll be lucky if you live long enough to finish reading this senten

    California is liberal only in that it is less conservative than other states. Our politics are all over the map. We want legalized marijuana, but three strikes. We want compassion for first offenders, but we demand the death penalty. We demand impartiality in the judiciary, and yet we require that judges be elected and stand for re-election every four years.

    As for the economics, we have a government whose spending has grown 40% in the last five years, and yet has had a combined population and price index growth rate of only 29%. We have no budget, spending expectations having outstripped revenue expectations by more than $15 billion out of $140 billion, nor do we have any signs of getting a budget soon, and the politics of the budget this year are even more brutal than past years. One Democrat who refused to cast a vote (she was protesting the refusal of the majority to bring up legislation she wanted heard) found that her office was moved across the street that afternoon on orders of the Democratic Majority Leader. (Not that her vote would have changed anything -- it still several votes short of passing.)

    Unemployment in California is at 7.3% as of August, up from 6.2% in May. It ranges from a low of 5.0% in Marin County to 23.3% in Imperial County (admittedly a smaller county). Los Angeles County is at 8.1%. The foreclosure rates for the state have tripled in the last year.

    There are states in worse shape than California (though I don't know if anyone has a budget mess as bad). Still, it's not exactly all peaches and cream in California.

    Besides, the price of homes there isn't just a measure of desirability, but also a measure of the ability of the economy to support those prices.

    No... it used to be. The price of homes in most non-rural areas is not an indicator of the economy's ability to support those prices. Hence the ever increasing foreclosure rate. Hence, house prices have gone up many times more than income (as a for instance, houses that were worth $30K here in a NY suburb 30 years ago are now worth $480K (nothing but upkeep). House prices have thus went up 16 times their previous value... while wages for such people have went up by a factor of 2.5 to 3.

    I doubt most of Cali or any other place that isn't rural or very close to rural isnt having the same problem. As the gap widens, it is going to become sickeningly obvious to more people that it's not what the economy can support that is driving house prices...

    AC: Ever worked a day in your life? I mean the hard kind of work that'll make you sweat during the day and blow black shit out of your nose and lungs at night? (or worse/similar) I doubt it.

    Some people in the US work for a living doing hazardous work. Yeah even more hazardous than jockeying that desk of yours all day.

    Of the things that can be hazardous for people to work with, some of them are hazardous to your lungs - like sand.

    "Play sand" like the kind you probably spend your days with has been thoroughly washed and graded for safety.

    People who work around industrial sand (anything from quarries to paint shops) and breath a lot of silicates (very fine sand) end up with cancer.

    I'm sure it's funny to you and some other people -- why else would so many signs be needed to point these things out?

    Sadly more people of your mind you do not expatriate to a place where they already do business "your way" such as...well, nearly any second or third world country. You can sprinkle lead paint on your corn flakes and have silica sand for desert if you like. Sure civilization has its warts, but if you don't like it, don't fake like there's no alternative and try to drag the rest of us back in time. Bye.
