OSHA determined that the employer of a 25-year-old welder – who suffered fatal injuries in an explosion in July 2022 – could have prevented the tragedy by following federal workplace safety standards. OSHA learned the explosion occurred during welding operations while the work crew replaced old metal tanks with fiberglass ones at a saltwater disposal site for oil and gas fields. The explosion sent seven of the company’s employees to local hospitals, including the welder who died as a result of his injuries six days later.
