The gas company agent was used to dealing with fire departments and checked the wrong box, even though his company could have supplied aviators breathing oxygen. The bottles on the servicing dolly were painted a dark green, not the apple green used for oxygen bottles. After the accident several pressurized turboprop and turbojet were grounded until their bottles could be correctly serviced.
