Carbon dioxide not suitable for extinguishment of smouldering fires 11 evident heat blister damage to a helmet and to a facial mask. The hood and jacket saw minor burn-through damage. One firefighter suffered burns to his hand because he had taken off one of his bulky gloves in order to operate the valve on the CO2 cylinder. After the explosion, the silo was considered a complete loss and an excavator was called in to tear a hole in the silo wall in order to empty the silo and extinguish the burning material outside. When the silo was torn open, a large surface fire was visible inside the silo. 4.5 Investigation Based on readings from the temperature sensors hung on wires inside the silo, the smouldering fire was believed to have started near the centre of the pellet pile. Pellets had not been drawn from the silo for two weeks and it was speculated that self-heating of pellets deep inside the undisturbed pile could have started an oxygen deficient smouldering fire. Pyrolysis gasses would then accumulate in the silo's headspace. The investigation identified the likely source of ignition to be a combustion zone break-through to the surface layer of the pellet pile. The wind was blowing steady at 8-10 m/s and the investigation report argued that sufficient turbulent entry of air through the 3 cm airgap between the shell and roof could have formed an ignitable pyrolysis gas mixture under the roof. In addition, that additional air entered the headspace through the open hatch when CO2 was injected due to backdraft and wind. The investigation did not identify electrostatic effects due to injection of carbon dioxide as a possible source of ignition. The national independent highly qualified senior fire investigator later stated that this mechanism was unknown to him. 4.6 Source of ignition Ignition may have been caused by a sudden combustion zone break-through to the surface layer or by static electricity. There is no empirical basis for this article to enter a discussion on the likelihood of either mechanism. From an industrial accident prevention perspective, what matters most is the lack of awareness of the hazard of electrostatic effects amongst emergency responders and accident investigators.
