A factory that supplies Apple and Nokia used the toxic solvent n-hexane

They said this manager was fired, and based on the number of employees spending sick days in the hospital, I'm sure the company ended up losing a lot of money on their medical bills.
This is hardly newsworthy. It happens all the time in China. Someone unethical wants to skim a little money by using cheaper chemicals, or wants to make a few more cents by producing faster using an unsafe process.
You can't blame Apple or Nokia. They likely dictated exactly what solvents were to be used, but the supplier decided they can hire fewer workers if they use the faster drying solvent, so they decided to cut corners.
These chemicals are having an effect on the Chinese economy, and thus the world economy (globalized economic impact), as well as in some cases the environment. That kind of changes whose responsibility it is, because it really does affect all of us (this is a localized case, but there are many American manufacturers who manufacture items in China with methods that severely harm the environment in and out of China). Apple really should maintain more control over manufacturing processes. As a major player in both the US and the entire world, and a representative of the US economically (this is important because we constantly ask 3rd world countries to cut emissions and regulate things like this), they have a responsibility to make sure they don't do things like this in all areas of product creation (just because its offshore and outsourced doesn't mean they have 0 responsibility) when the cost of ensuring it to them would be essentially unnoticeable.
If it would be extremely costly to do this kind of regulation (since the Chinese obviously wont) on Apple's part, it would be reasonable to discount their responsibility, but it really wouldn't be that expensive if they wanted to. It's a bit naive to assume that Apple isn't knowingly turning a blind eye to manufacturing conditions. Apple obviously knows things like this are prone to happen when you outsource manufacturing in 3rd world countries, so maybe we should be asking them to do a better job of regulating who they do business with considering the range of impact they actually have...
I think that there is a reason why other companies haven't done or published an audit like Apple... they don't want to know the results. If they knew the results, then they'd be obligated to do something about it.
Basically, the problem is more the volatility than anything else, so it may be bad for the poor Chinese people working "just there" but for the end user in Europe, this is safe as it will have evaporated long before reaching us.
Call me a cynical, but for one case like that, how many unknown cases? Especially because in China/India, you contract one company which will sub contract to an array of smaller companies with often very bad working conditions.
Take water (dihydrogen monoxide) for an example - you can drown in it. Or pure ogyxen - extremely flammable.
So it isn't about toxic substances - it is about handling them with care.
But your point about handling them with care is correct. You can use n-hexane, but only if you handle it properly.
