Nitrogen Leak at Paris Gym Claims Life, Leaves One Critically Injured

Authorities investigate equipment failure and plumbing repairs after fatal cryotherapy incident in the 11th arrondissement.

A nitrogen leak during a cryotherapy session at On Air Gym in Paris resulted in the death of a 28-year-old employee and critically injured a 33-year-old client.
The incident occurred on the evening of April 14, 2025, at the gym located on Boulevard Voltaire in the 11th arrondissement.
Preliminary findings suggest the nitrogen leak originated from cryotherapy equipment, potentially linked to plumbing repairs conducted earlier that day.
An investigation led by Paris police and labor inspectors is underway to determine the exact cause of the leak and assess safety protocols.
Emergency services responded promptly, evacuating the gym and assisting the victims, while autopsy and toxicology analyses have been ordered.
