An August 28, 2016, nitrous oxide explosion at an Airgas facility (acquired by Air Liquide in 2016) in Cantonment, Florida, killed employee Jesse Folmar and caused extensive structural damage, attributed to operational issues in a high-pressure system; the U.S. Chemical Safety Board noted similar incidents occur roughly every four years at U.S. nitrous oxide plants since 2001, and OSHA fined Airgas $12,000 for related safety lapses.[141][143][144]

In May 2023, an explosion at Air Liquide Advanced Materials' plant in High Springs, Florida, injured four workers, including one with life-altering injuries from burns and trauma, due to the use of unrated equipment in a hazardous atmosphere and failure to follow lockout/tagout procedures; the U.S. Department of Labor's OSHA investigation cited 12 serious violations, including willful exposure to fire and explosion hazards, proposing $201,573 in penalties.[145][146]

Other notable violations include a July 2016 OSHA fine of $77,000 against Air Liquide for two safety shortcomings at a steam methane reformer in Corpus Christi, Texas, involving inadequate hazard assessments.[5] In July 2018, a U.K. court imposed a £243,000 ($308,000 equivalent) penalty on Air Liquide for exposing workers to toxic vapors in a 2015 incident due to poor emergency planning and supervision, as determined by the Health and Safety Executive.[5] Pre-acquisition Airgas incidents, such as the 2008 argon asphyxiation deaths of three stevedores in Port Everglades, Florida, resulted in a 2016 federal fine of $4.3 million and $2.7 million in restitution, with two years' probation.[5]

Legal Challenges and Regulatory Settlements

In merger transactions, Air Liquide has faced antitrust scrutiny from U.S. regulators, leading to consent orders requiring asset divestitures to maintain competition in industrial gases markets. For instance, in its 2004 acquisition of Messer Griesheim GmbH for $3.5 billion, the Federal Trade Commission (FTC) mandated the divestiture of six air separation units (ASUs) and related assets in California, Texas, Louisiana, and Mississippi to a single buyer within six months, addressing concerns over reduced competition and potential price increases for liquid oxygen, nitrogen, and argon.[147] Similar conditions applied to earlier deals, such as the FTC's review of Air Liquide's involvement in the proposed Air Products and BOC merger in 2000, which involved coordinated international antitrust cooperation but ultimately required divestitures to resolve overlapping market concentrations.

In France, subsidiaries of Air Liquide were fined by the Conseil de la concurrence (now Autorité de la concurrence) for anticompetitive practices in the hospital medical gases sector. In January 2003, the authority imposed penalties totaling €4.3 million on Air Liquide Santé, Liquid Air, and Sepi for practices including market sharing, bid-rigging, and exchange of sensitive information between 1992 and 2001, which restricted competition in supplying medical gases to hospitals.[148][149]

Air Liquide has settled multiple environmental violations under the U.S. Clean Air Act, primarily involving ozone-depleting substances. In June 2001, the U.S. Department of Justice and Environmental Protection Agency (EPA) resolved claims against Air Liquide America Corporation for exceeding leak rates in industrial refrigeration systems at 22 facilities across 18 states, failing to repair leaks before recharging with chlorofluorocarbons (CFCs), inadequate record-keeping, and using uncertified technicians; the settlement included a $4.5 million civil penalty, retrofitting or replacing 46 systems with non-CFC alternatives, retiring seven systems, and donating land parcels valued at $500,000 for environmental and community uses.[150] Aggregate environmental penalties since 2000 exceed $14.7 million across 52 incidents, including a $7 million hazardous waste fine in 2016 related to a subsidiary's operations and a $538,780 air pollution settlement in 2016.[151]

Regulatory settlements have also addressed workplace safety violations under the Occupational Safety and Health Administration (OSHA). Following a 2023 explosion at Air Liquide Advanced Materials' facility in High Springs, Florida, OSHA cited the company for seven serious and one willful violation, proposing $201,573 in penalties for failures including inadequate process safety management and hazard assessments that prioritized production over worker safety.[146] Additional OSHA fines include $77,000 in 2011 for violations at a Corpus Christi, Texas plant involving deficient hazard communication and electrical safety.[152] These cases reflect ongoing regulatory oversight of Air Liquide's handling of hazardous gases and processes.[153]
