Exposure to two compounds approved can result in ‘sudden death’ and range of other serious health risks, lawsuit warns

The Trump administration has approved two new datacenter chemicals to which exposure can result in “sudden death” and a range of other serious health risks, like cancer, eye corrosion, neurological damage and reproductive harm, a new lawsuit warns.

The two compounds approved by the Environmental Protection Agency (EPA) for import and immediate use in facilities across the US are photoacid generators that also appear to be Pfas “forever chemicals”, though it is unclear because much of the EPA documents are redacted. Some Pfas are commonly used in the production of semiconductors.

This article was amended on 26 August 2026. A previous version said the EPA concedes that the chemicals present an “unreasonable risk” to workers. It has been updated to say the chemicals may present an unreasonable risk.

Jack Klein takes heat readings, gives fans to overheated passengers and lugs big jugs of water into the stations

On a recent August day in the subterranean furnace of New York City’s subway, one bearded, curly haired man was studying his phone for different reasons than the other wilting passengers – to track the soaring temperatures and ponder how underground train stations can cool down in an era of climate crisis.

Jack Klein, a 31-year-old construction site manager, has in the past two years taken it upon himself to become a sort of guerrilla subway heat operative, sticking teardrop-shaped thermometers to steel beams in seven of the hottest Manhattan stations and posting social media videos of the hades-like summer temperatures that commuters have to endure.
