The tanker truck was carrying nearly 13,000 gallons of liquid hydrogen. it hit the base of a light pole in the parking lot of a local grocery store as the driver was attempting to turn around. Hydrogen gas then began leaking out of it. This resulted in a valve on the truck to become damaged and could have caused the liquid hydrogen to be released from the truck, a very serious situation for nearby residents and businesses. Nobody was physically harmed by the incident.

The incident occurred at a fuel cells manufacturing plant. The tanker was preparing to transfer liquid hydrogen to the company hydrogen bulk storage tank. During backing, it impacted an industrial building, causing a hole in the tank, with consequent leak and ignition. When the City fire brigade arrived on scene, the hydrogen gas was still escaping from the leak feeding the fire. They let the fire burn out and kept dousing the tanker till Saturday to reduce the temperature and to minimise possible the risk of explosion.

a hydrogen recycle compressor shut down unexpectedly, resulting in flaring activity with visible smoke.

A hydrogen plant exploded, throwing debris for tens of metres and badly damaging the plant. The two workers in the plant at the time were not seriously injured. The plant reportedly had a capacity of 3,600 tonnes/year of liquid hydrogen. On November 13 it was reported that the Commission de la sant et de la scurit au travail (CSST - Commission for Health and Safety at Work) would not be conducting an inquiry because no one was killed. On November 19 it was reported that the liquid hydrogen section appeared to have been destroyed.

On a cold morning, the gasoil hydro-treatement unit was being brought back on line after being out of service to repair a governor problem on the recycle gas compressor. Several upset trips had occurred in the previous month but these were not seen to have any direct bearing on the operation of he hydrogen heaters or the unit as a whole, Temperature at the coil outlet of both heaters was at least 100 degrees C lower than normal since the unit was in a start up mode. The reactor circuit was at full operating pressure while hydrogen was recycled via a compressor.

Hydrogen leak from a valve, with delayed ignition and consequent engulfing fire.The bonnet of a 2 inch valve on hydrogen quench line of a lube oil hydrotreater began to leak.The operative conditions were at 3000 psi and 730 degrees F (ca. 200 bar and ca. 390 C). 12 minutes later ignition occurred with fire engulfing the upper portion of the unit. The gas could not be blocked in and the fire burned for over 2 days.

A severe fire in a hydrogen compressor building in a unifier unit of an oil sands refinery reportedly started in a 1,500 psi lube oil system. Fire fighting was difficult because of 40 degrees F temperatures. The building reportedly housed three centrifugal hydrogen recycle compressors, a centrifugal natural gas compressor and two 4,000 horsepower reciprocating compressors.

The event occurred in the hydrogen pumping station, placed between the hydrogen production unit (steam methane reformer) and the hydro-treatment unit. The second stage of the compressor cylinder released hydrogen into the confined compressor building, and which ignited. The failure was caused over-pressure in the piston, probably induced by ice blockage on the interstage cooler and the failure of the compressor housing heating system.

Explosion at styrene plant during start-up. A manhead flange failed in a light oil hydrogenation unit releasing 30 kg of hydrogen in a compressor shed. Ignition occurred in 10 to 15 secs. Significant damage to building and structures. Window damage to 365 m. According to the H2TOOLS entry, the investigation team concluded that hydrogen gas was released through a failed 19-inch diameter gasket and ignited under the roof of the compressor shed where it was partially confined.

A jet fire occurred on the ammonia production unit, caused by a leak on a hydrogen pipe. No victims.
