SAFTENG Comment:
A basement is NOT by definition a “confined space”. That does not mean that a basement cannot have a hazardous atmosphere. Argon is 1.38 times heavier than air and with NO ventilation designed to remove this gas from a basement, it will displace the Oxygen leading to this horrific event. So many failures in this event to learn from.
On January 30, 2023, at approximately 5:30 p.m., argon gas was released at a facility. Exposure to the argon gas fatally injured two employees, who asphyxiated.
