Chemical accidents involving hazardous materials have surged by 57% between 2021 and 2025, with reports of incidents rising from 83 to 131, according to an analysis by Public Employees for Environmental Responsibility (PEER). This alarming trend coincides with the Trump administration's proposals to roll back essential safety regulations aimed at protecting workers and communities from catastrophic chemical releases.
Rising Rates of Chemical Accidents
Injuries and fatalities from chemical accidents have also escalated during this period, increasing from 60 to 89. The Chemical Safety Board (CSB), which investigates such incidents, reported over 650 accidents between April 2020 and May 2026, resulting in 103 fatalities and 355 injuries. Close to 150 million people live within three miles of facilities using highly hazardous substances, highlighting the potential risk to communities, especially those historically underserved.
Hydrofluoric Acid: A Dangerous Chemical
Hydrofluoric acid (HF), a key ingredient in various industrial processes, is among the most corrosive and dangerous chemicals. Experiments conducted by physicist Ronald Koopman in the 1980s demonstrated the severe risks associated with HF spills. During a test, a release of 1,000 gallons of HF formed a ground-hugging mist that traveled far beyond expectations, illustrating the potential for disaster.
Koopman emphasized the dangers of allowing refineries, many built before 1985, to operate near populated areas. His concerns were echoed following a significant explosion at the Philadelphia Energy Solutions refinery in 2019, which released over 5,000 pounds of HF. Fortunately, the nearby community was spared only due to favorable wind conditions.
Regulatory Changes Under the Trump Administration
Despite the rising accident rates, the Trump administration has sought to weaken the Risk Management Program (RMP) regulations established under the Clean Air Act. These rules require facilities to implement safety measures to prevent accidents, including analyses of safer alternatives and independent investigations of incidents. Recent proposals have drawn criticism from environmental advocates, who argue that the rollback could lead to more accidents and increased risks for nearby communities.
The Biden administration has indicated plans to strengthen RMP rules, emphasizing the need for enhanced safety measures. An EPA spokesperson noted that the agency is reviewing public comments and aims to finalize the new regulations by late 2026. However, the effectiveness of these measures remains under scrutiny, as PEER's Ruch stated, “the conclusion that any decline is due to industry prevention plans is a supposition which the current EPA does not have the data to support.”
