"Hazardous chemical releases from industrial accidents that injured or killed people increased by nearly 50 percent in recent years."
"Physicist Ronald Koopman appeared at a Southern California Air District meeting in 2018 to talk about what seemed like an arcane scientific topic: hydrofluoric acid dispersion and water mitigation testing.
Hydrofluoric acid, also known as hydrogen fluoride or HF, is used to manufacture a range of materials, including refrigerants, gasoline, fluorine-based pesticides and fluoropolymers like those used to make Teflon. It’s also one of the most corrosive and dangerous chemicals known. Koopman conducted experiments with the chemical in the 1980s that warned about the potential of deadly accidents at facilities that use the hazardous materials.
With the Trump administration poised to roll back rules intended to protect workers and communities from catastrophic industrial chemical releases, and a new analysis showing rising rates of chemical accidents, Koopman’s presentation on highly hazardous materials has taken on a new urgency.
The number of accidents involving releases of dangerous chemicals rose by 57 percent between 2021 and 2025, from 83 to 131, according to an analysis released Monday by Public Employees for Environmental Responsibility, a nonprofit that works with former government officials."
