OSHA issues $1 million fine to four companies in connection with incident that led to worker deaths
On Jan. 28, 2021, six workers went to work at a poultry processing facility unaware that they would not return home. Just after their shift began, a freezer at the plant malfunctioned, releasing colorless, odorless liquid nitrogen into the plant’s air, displacing the oxygen in the room.
Three of the plant’s maintenance workers entered the freezer room without precautions — never trained on the deadly effects of nitrogen exposure — and were overcome immediately, according to OSHA. Other workers entered the room and were also overcome. The three maintenance workers and two other workers died immediately, a sixth died on the way to the hospital. At least a dozen other injured workers needed hospital care.
Upon investigation, OSHA cited four companies — all of whom the agency says are responsible for operations at the facility — for a total of 59 violations and proposed $998,637 in penalties.
OSHA cited the processing facility for 26 violations, including six willful violations for exposing workers to thermal injuries and suffocation hazards resulting from the uncontrolled release of liquid nitrogen; failing to develop, document and use lockout procedures; not informing employees that liquid nitrogen, an asphyxiate, was used in the onsite freezer; not training employees on the methods and observations used to detect the presence or release of nitrogen; failing to train workers on the hazards of liquid nitrogen, and not training employees on the emergency procedures they can take to protect themselves. In addition, the employer failed to:
- Provide workers with access to the safety data sheet on liquid nitrogen, or label the freezers properly with hazard warnings.
- Perform a hazard assessment for exposure to liquid nitrogen.
- Implement a permit-required confined space program for workers who entered the liquid nitrogen freezer, and notify contractors required to work inside the liquid nitrogen freezer that it was a permit-required confined space.
- Make sure multiple egress paths in the facility were free from obstruction.
- Illuminate exit signs, provide adequate lighting for exit routes, and ensure exit access was at least 28 inches wide.
OSHA also cited the company that delivered the industrial gas to the facility for six serious violations. The agency found this company exposed workers to injuries and suffocation from the uncontrolled release of liquid nitrogen; failed to ensure an egress path was unobstructed; and did not develop, document and use lockout procedures, nor ensure lockout procedures were shared between the host employer and contractors.
The agency cited the company that provided cleaning and sanitation services at the facility for 17 serious and two repeat violations for failing to train workers on the hazards of liquid nitrogen and anhydrous ammonia, and not ensuring emergency eye washes were available and unobstructed.
OSHA also cited the company that manufactures equipment and provides mechanical servicing to the facility, for eight serious violations for failing to train workers on the physical and health hazards of liquid nitrogen and emergency procedures related to liquid nitrogen. The company also failed to ensure the development and use of specific written lockout procedures and ensure that the host employer and contractors shared information on lockout procedures.
OSHA's multi-employer citation policy could be put to the test
Because OSHA cited four companies, even ones that supplied the gas and provided cleaning services, it could be a tricky case to stick, should the citations be contested. While OSHA can certainly cite multiple employers under the Agency’s Multiple Employer Citation Policy, the facts of the case dictate whether those will hold up if challenged in the courts. Either way, it shows that employers who do business or provide services at another employer’s location, need to pay close attention to safety hazards in the facility.
