O2 Fire - Soviet
Navy Chamber | 11/17/1962 | Crew: 4 | Crew Injury (4)
Fire started in a 100% oxygen environment at 5 psi. Four officers injured.
On November 17, 1962 four Navy officers were injured, two seriously, when a fire started in the altitude chamber they were occupying in a 20 day experiment at the U.S. Navy Air Crew Equipment Laboratory as part of a NASA atmosphere validation program.
The chamber contained 100% oxygen at 5 psi. The fire started when one officer changed a light bulb in an energized 24 volt DC light fixture. One wire in the fixture became disconnected resulting in arcing. A cotton towel was used in an attempt to smoother the fire. The towel caught fire, and the flames spread to the officers' clothes.
Altitude Chamber O2 Fire | 3/23/1961 | Crew: 1 | Loss of Crew
Alcohol wipe hit hot plate and started fire in oxygen-rich test chamber.
On March 23, 1961 a cosmonaut in an altitude chamber was removing the sensors that had been attached to him during an experiment. He cleaned the places where the sensors had been attached with cotton wool soaked in alcohol, and without looking threw away the cotton wool. The cotton wool landed on the ring of an electric hot plate in the oxygen-charged atmosphere of the chamber. In conditions of high oxygen concentration, normally non-flammable substances can burn vigorously. The cosmonaut's training suit caught fire. Unaccustomed to the vigor of high-oxygen fires, the cosmonaut would only have spread the flames further by attempting to smother them. The doctor on duty noticed the conflagration through a porthole and rushed to the hatch, which he could not open because the internal pressure kept the inward swinging hatch sealed. Releasing the pressure through bleed valves took several minutes and the cosmonaut later died in the hospital from the burns.
