    1. 火災隱患多
空調制冷設備、貨物傳輸設備、照明設備等電氣或機械故障，聚苯乙烯泡沫保溫材料，塑料包裝材料，木制棧板充斥在冷庫內部。冷庫內溫度非常低，長期造成電纜線塑料外皮變脆而容易破損，進一步造成線路短路而燃燒，且冷庫內空氣異常干燥，起火后燃燒非常迅速。
Air conditioning refrigeration equipment, goods transport equipment, lighting equipment, such as electrical or mechanical failure, polystyrene foam insulation materials, plastic packaging materials, wooden pallet are full of inside the refrigerator. Cold storage temperature is very low, long-term cause cable plastic skin become fragile and easily damaged, causing a further short circuit and burning, and cold storage anomaly of the air inside dry, after a fire burning very quickly.
2. 傳統探測器無法使用
Traditional fire detectors are not suitable for installation inside the cold storage, cold storage due to the internal temperature is too low, will cause the detector frost or malfunction.
3. 火災撲滅困難
冷庫內部空間封閉煙霧久聚不散，大火沿著保溫材料蔓延燃燒，內部空間大，貨架多，水槍難以對起火點冷卻滅火。
Refrigerator internal space closed smoke for a long time do not come loose, the fire spread along the heat preservation material combustion, internal space is large, shelves, nozzle of the fire extinguishing cooling hard.
