737 Destroyed During Oxygen Refill Operation

A 737 aircraft landed at an airport near the Caspian Sea. 142 passengers had departed along with the 5 crew members. The crew reported that the cabin oxygen pressure was at 900 psi. The ground crew was attempting to trans fill the oxygen from an 1800 PSI oxygen source. It is reported that the ground crew tested the equipment to assure the supply gas was at 1800 psi.

2 Gas Cylinder Ruptures Delay Vessel Operation Over 8 Months

Ships and buildings are outfitted with inert gas fire suppression systems. In the event of a fire, the cylinder valves activate, filling a room or compartment with inert gas, displacing the oxygen. Since fire requires oxygen to continue combustion, removing the oxygen from the room or compartment stops the fire.

Facilities and companies follow strict regulations and safety protocols to prevent accidents. The aviation industry is just one example where safety is paramount. If an issue develops on a plane it could be catastrophic. Aviation systems are engineered to the highest standards, and the slightest issue can ground a plane. Systems are checked, re-checked and pre-flight inspections are conducted before each flight.

Cleaning Cylinders

Cylinders are expected to be clean and store their contents without any additional contaminates. If the interior of the cylinder has not been exposed to a contaminate, the gases it supplies should be as pure on the date of discharge as its purity on the date it was added to the cylinder. However, during its normal use, contaminates can enter the cylinder in some unintentional circumstances. Examples include: contaminated water may not be fully removed after hydrostatic requalification’, an improperly functioning compressor may add oil, contaminates may be added if the cylinder loses pressure and creates an interior vacuum or an unsuspecting person may add a component unknowingly. In any of these circumstances, procedures need to be developed to remove the contaminates and maintain the cleanliness of the cylinder.
