Emergency treatment of sulfur hexafluoride leakage

Sulfur hexafluoride is a choking agent that, at high concentrations, causes dyspnea, wheezing, skin and mucous membranes to turn blue, and systemic spasms. After a few minutes of inhalation of a mixture of 80 percent sulfur hexafluoride and 20 percent oxygen, the body experiences numbness in the extremities and even death by suffocation. According to the regulations of China, the allowable concentration of sulfur hexafluoride gas in the air in the operation room should not be more than 6g/m3 or the oxygen content in the air should be more than 18%; For short-term exposure, the allowable concentration of sulfur hexafluoride gas in the air shall not be greater than 7.5g/m3. Sulfur hexafluoride is an inert gas in pharmacological action, low toxicity but has a suffocation effect on the human body. Low - fluorine compounds and fluorooxygens that break down trace amounts of toxic sulfur during life or use.

Security checks of prevent SF6 leakage

Emergency measures:

1)Get away from the scene to fresh air. Keep your respiratory tract open. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Go to a doctor.

2)The product won't burn. Cut off the air supply. Spray water to cool the container and, if possible, move the container from the fire to an open area

3)Quickly evacuate the contaminated area to the wind, and quarantine, strictly restrict access. It is recommended that emergency responders wear self-contained positive pressure respirators and general work clothes. Cut off the source as much as possible. Reasonable ventilation and accelerated diffusion. Use immediately if possible. Leaky air containers should be properly handled, repaired, inspected before use.
