It has the same LD50 dose as HCN. It literally _is_ just as bad. It routinely kills people on oil rigs because in lethal concentrations it immediately shuts off your nose.
How often do you hear about people getting poisoned by it from lead-acid batteries?
- zdragnar 7mo agoThe only people with any significant amount of lead acid batteries on their property are off grid types who typically store them away from their primary domicile as a fire safety precaution. Fast charging a car/chemical weapon in your garage isn't terribly appealing.
- Dylan16807 7mo agoIf that battery is a chemical weapon then so is a big half-plastic box with ten gallons of gasoline inside.
- gilleain 7mo agoNot precisely the same: https://en.wikipedia.org/wiki/Hydrogen_cyanide https://en.wikipedia.org/wiki/Hydrogen_cyanide - 107 ppm (human, 10 min) https://en.wikipedia.org/wiki/Hydrogen_sulfide https://en.wikipedia.org/wiki/Hydrogen_sulfide - 600 ppm (human, 30 min) https://en.wikipedia.org/wiki/Carbon_monoxide https://en.wikipedia.org/wiki/Carbon_monoxide - 4000 ppm (human, 30 min) These are "LCLo" values from the databoxes on those pages. More easily comparable numbers may be around somewhere.
- WarmWash 7mo agoHydrogen cyanide has the bonus of being mostly odorless too. Whereas hydrogen sulfide is distinctly bad smelling.
- ted_dunning 7mo agoApparently it only smells bad if you have non-lethal concentration.
