A hydrogenation experiment was being performed under 60 atm hydrogen, inside a high-pressure reactor cell. The experiment was conducted inside a fume hood and left overnight. The hood caught fire during the night, resulting in fire damage to the fixture, hood, and exhaust duct, as well as water damage to much of the building. Based on the local fire department investigation, the fire started from faulty electrical wiring that was used to provide power for reactor cell heating. The electrical fire ignited solvent that was in a dispensing bottle inside the hood, which subsequently overheated the reactor cell, rupturing the seals. The rupture released hydrogen from the cell and attached supply tank, further fueling the fire. Nobody was injured in the incident, and damages were limited. It view more
A refinery hydrocracker effluent pipe section ruptured and released a mixture of gases, including hydrogen, which instantly ignited on contact with the air, causing an explosion and a fire. Excessive high temperature, likely in excess of 1400°F (760°C), initiated in one of the reactor beds spread to adjacent beds and raised the temperature and pressure of the effluent piping to the point where it failed. An operator who was checking a field temperature panel at the base of the reactor and trying to diagnose the high-temperature problem was killed. A total of 46 other plant personnel were injured and 13 of these were taken to local hospitals, treated, and released. There were no reported injuries to the public.
Property damage included an 18-inch (46-centimeter) long tear in the view more
