What is the emergency treatment method for R22 refrigerant leakage

R22 refrigerant has low toxicity, but some of the cracked gas and residual liquid components produced by using it to prepare tetrafluoroethylene are highly toxic, which can cause acute poisoning. Mild cases of poisoning include cough, chest tightness, dizziness, fatigue, nausea, etc. Animal experiments show that R22 refrigerant has anesthesia and cardiotoxicity. So what is the emergency treatment method for R22 refrigerant leakage? What first-aid measures should be taken when the human body comes into contact with R22 refrigerant? Take a look at the answers from the refrigeration experts.

What is the emergency treatment method for R22 refrigerant leakage

　　 R22 refrigerant leakage emergency treatment method:

　　 The warning zone is delineated according to the gas affected area, and irrelevant personnel are evacuated from the crosswind and upwind to the safe zone. It is recommended that emergency personnel wear positive pressure self-contained breathing apparatus and general work clothes. Do not touch or cross the spill. Cut off the source of leakage as much as possible. The sprayed water suppresses the vapor or changes the direction of the vapor cloud to prevent the water from contacting the leakage. It is forbidden to directly impact the leakage or the source of leakage with water. Prevent the diffusion of gas through sewers, ventilation systems and confined spaces. Leaked gas is allowed to be discharged into the atmosphere. Keep the leaking place ventilated.

　　What first-aid measures should be taken when the human body comes into contact with R22 refrigerant:

　　 Skin contact: Take off contaminated clothing immediately, and rinse with plenty of running water for 20-30 minutes. If you feel uncomfortable, seek medical advice. Eye contact: Lift the eyelids immediately and rinse them thoroughly with plenty of running water or normal saline for 10-15 minutes. If you feel unwell, seek medical advice; inhalation: leave the scene quickly to a place with fresh air. Keep the airway open. If breathing is difficult, give oxygen. Breathing and heartbeat stop, immediately perform CPR. Seek medical attention; ingestion: will not be exposed through this route.
