Though there ocurred many ammonia accidents all the time ,and is too dangerous for people .But the ammonia refrigeration industry believes there is considerable security risk, but in our country, a complete ban on the use of this low-cost ammonia cooling mode is not realistic.
So what measures do we should take ? The cube ice machine factory general manager suggest follows:
" Multifaceted strengthen supervision, improve the relevant government department staff , business leaders and industry security awareness practitioners are the most important,"Guo tiancheng said, "If the regulatory merely going through the motions , safety awareness is still weak , similar incidents will happen . "
At present, China only a few places for ammonia production using to develop the relevant technical specifications . The industry believes that , due to the corrosive properties of liquid ammonia and easy to react with the metal , ammonia equipment requires strict quality standards, the vessel thickness, material purity must strictly regulate . In addition, the safety standards should involve lightning , anti-static, transport, handling , emergency rescue and other content.
In the production of ammonia refrigeration safety , refrigerant charge of the refrigeration system is very important, but in practice has not been effective attention. " Rigorous induction training is ' standard ' ."Guo tiancheng said, " These operators should be allowed to the principle of ammonia systems , characteristics, emergency measures Familiarize heart and refrigeration skills regularly audited by non-compliance induction is strictly prohibited . "
Guo Tiancheng believes that the actual production safety supervision process, often encounter through formal Design Institute plant was unable to meet fire, safety supervision department standard situation. He said: "The standard theory and practical standards difference is too big , not strong operational safety regulations is widespread ." Experts recommend regulatory authorities and enterprises to better communication standards to be realistic , so that local conditions as possible.
