The pressure drop in the fire-fighting gas cylinders and the insufficient pressure caused the fire extinguishing agent to be discharged normally, which hindered the fire-extinguishing efficiency.
Corrosion of the inner wall of the bottle becomes thinner, and the leakage of the medicament results in the inability to extinguish the fire normally. There is a serious risk of explosion.
The outside of the bottle body is corroded, and the wall thickness becomes thinner, which leads to the risk of leakage and explosion of the gas cylinder, which may cause serious casualties.
