Expert calls violations a ‘crimson flag’
The extra than one tools failures and safety violations are a “crimson flag” for this firm, talked about Stephen Kmiotek, a chemical engineering professor on the Worcester Polytechnic Institute who has carefully adopted the fatal accident and its aftermath.
“My affect, you place it all collectively, including the most smartly-liked tank give device, is it is miles a self-discipline that has no longer been maintained, and that creates possibility to workers and possibility to public,” he talked about.
Company says firm knew tank modified into once ‘no longer fit for persisted service’

Federal response center acquired calls of toxic chemical discharges
Eight times between 2017 and 2023, the U.S. Environmental Protection Company’s National Response Heart acquired reviews of methyl mercaptan releases from the plant.
Methyl mercaptan is a colorless flammable gas. Exposure can induce headache, nausea, and loss of life, in step with the Facilities for Disease Control and Prevention. Four workers were killed in a 2014 methyl mercaptan leak at a DuPont industrial plant in suburban Houston.
State ecology inspectors were notified in regards to the September 2017 methyl mercaptan open, announcing in emails that a non-public citizen modified into once hospitalized on account of publicity. They additionally investigated smell complaints.
Residents on a current basis reported rotten smells spherical the plant that in most cases made them sick and saved them interior. Ecology officials fined Nippon $4,500 in 2024 for releasing unsuitable portions of sulfur dioxide, a toxic gas with a stable smell.
A history of tools failures
