True, but I'm basing my statement on risk assessment from a personal level in a well run facility with proper hazardous material handling equipment. Not standing next to an uncontained and uncontrolled tank - which I definitely wouldn't want anyone to ever do. I'm pretty sure it's also nearly unheard of. Even the backwoods places I've seen re-chroming hydraulics in the mountains for logging and mining equipment have some serious collection and disposal systems.
Point being, there's no way to mitigate all risks to zero, only minimizing them where feasible. Outright bans are an 'easy button' approach to a supposed problem and I find that approach silly. At least in this case, there are likely to be ways to deal with it and so the losses as a result of a ban are not likely to be as bad as many assume they will be.
