In Japan an explosion accident at pellet RDF(Refuse Derived Fuel) silo happened causing serious damage to surroundings a few years ago. When a RDF pile was stored for a long-time, a spontaneous combustion and a subsequent explosion phenomena were reported. In this study the property change of pellet RDF that was made of municipal solid waste and stored for a long time in storage silo was investigated for one year in order to understand the reason of explosion and to find how to prevent the accident. We measured silo temperature and concentration of H_2, CH_4, CO_2 and CO gases from silo body and top. Concentrations of CO_2 and H_2, which indicate the fermentation reaction of organic compounds inside municipal solid waste, were increased by the increase of temperature inside silo that was affected by atmospheric temperature. Especially CO_2 concentration was found to be a good correlation with temperature change that was caused by fermentation of organics. It is recommended for RDF silo safety that temperature and CO_2 concentration should be kept under 40oC and 1% inside silo, respectively.
