The thermal bag was folded over and loosely taped closed. Outer box had shipping and hazmat label, inside that box was thermal wrap/bag (see pics) which was basically bubble wrap with a Mylar coat, inside the thermal bag was the food product box and loosely placed dry ice pellets. The boxes were found to be damp but in good condition. Shortly after “he was able to demonstrate to the firefighter that he was coherent by answering a series of relatable questions”. The pilot was brought round by a ‘ sternal rub‘ but initially his speech was unintelligible. The fire service chocked the aircraft and shutdown the engine. A firefighter on reaching the aircraft observed “an occupant with his head rolled back and his mouth open”. Remarkably only after the pilot had failed to respond to repeated calls from air traffic for c20 minutes, did aid reach the aircraft. He stopped the aircraft at the runway run-up area and momentarily closed his eyes. While taxing to runway 30R the pilot felt “strong sleepiness” accompanied by difficulty breathing. The evening was cool and so the pilot closed the ventilation. On the of the incident, the packages were placed behind the cockpit in zones 1, 2, and 3 for even weight and balance distribution.Īfter the loading was completed, the pilot finished his paperwork and started the aircraft at 17:29. The pilot stated that he infrequently flies with dry ice and when he does, he usually only has about 10 boxes with him (also at 0.9 kg per box) and usually places them in cargo zones 5 or 6 (near the back), not zones 1, 2, and 3, which are located right behind him. Put the affected body part in a bath of warm water-not above 40° C, or 104° F.Markings on One of 41 Boxes – West Air Cessna C208B N781FE (Credit: FAA via NTSB)Ī FedEx dangerous goods representative had approved the shipment as the dry ice mass furnished by the shipper was below the company’s limit of 76 kg for the C208B.Remove clothing that is not frozen to the skin.Get medical assistance as soon as possible.OSHA recommends treating dry ice contact injuries as possible: Skin contact with dry ice can cause frostbite. The cold can weaken adhesives and cause cracking. ♺void putting dry ice directly on tile or laminated countertops. Never dispose of dry ice in a trash can.Never dispose of dry ice in a toilet, sink or garbage disposal.♽o not leave dry ice unattended in public places. Make sure to allow dry ice to sublimate only in well-ventilated areas to avoid a harmful buildup of CO2. Other symptoms of carbon dioxide poisoning are similar to those of oxygen deprivation (suffocation) and include headache, dizziness, drowsiness, and if left untreated UNCONSCIOUSNESS, AND DEATH.Īllowing dry ice to sublimate at room temperature is an effective way to dispose of it, but it's important to take precautions to help prevent hazards. Rapid breathing is an early symptom of carbon dioxide exposure. It quickly replaces oxygen in the air and thus poisoning and suffocation can be caused by dry ice sublimating in enclosed, poorly ventilated spaces. Carbon dioxide is in the air we breathe and at high concentrations it has toxic effects. It is used in many industrial applications, frequently for preserving frozen foods in the shipping process.Įven small amounts of Dry Ice can produce large quantities of carbon dioxide as it turns from a solid to a gas. This means that dry ice will evaporate without leaving moisture or wetness. Sublimation is when a substance turns directly into a gas without first becoming liquid. Above this temperature, dry ice sublimes, or sublimates. The surface temperature of dry ice is –109.3° F (–57° C). THE OCCUPANT WAS THEN FOUND DEAD OF SUFFOCATION IN THE WRECKED CAR.ĭRY ICE is frozen carbon dioxide (CO2). The occupant (unaware of a problem) then entered the car (closed the door) and drove off in a car with no oxygen. The dry ice sublimated to CO2 and oxygen was then replaced with CO2. Carbon Dioxide (Sublimation of DRY ICE) PoisoningĬASE REPORT: DEATH FROM IMPROPER HANDLING OF DRY ICEĪfter removing the frozen food from the boxes, the opened boxes (with dry ice still in them) were left open in the back seat of the car.
