Liquid nitrogen quick freezing and emergency treatment
Emergency treatment
Emergency treatment: Quickly evacuate personnel from the leaked contaminated area to the upper wind, and isolate them, strictly restrict access. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and wear cold-proof clothing. Do not directly touch the leakage. Cut off the source of leakage as much as possible. Use the exhaust fan to send the leaked gas to the open place (liquid nitrogen quick freezing). Leaking containers should be properly handled and used after repair and inspection.
Liquid nitrogen leakage treatment method
When inhaled (liquid nitrogen quick-freezing) nitrogen concentration is not too high, the patient* initially feels chest tightness, shortness of breath, weakness, and then irritability, extreme excitement, running around, yelling, trance, and unsteady gait, which is called "nitrogen "酩酊", can enter a state of lethargy or coma. Inhalation of high concentrations, the patient can quickly become unconscious and die due to the arrest of breathing and heartbeat.
1. Quickly evacuate personnel from the leaked contaminated area to the upwind, and set up isolation areas to strictly restrict access.
2. Notify the fire and related units.
3. Emergency personnel should wear self-contained positive pressure breathing apparatus, cold-proof clothing and cold-proof gloves.
4. Avoid leaking liquids from flowing into basements or other confined manned working spaces. If it is unavoidable, notify relevant departments immediately.
5. Do not directly touch the leakage.
6. Cut off the source of leakage as much as possible.
7. Water spray can be used to accelerate the evaporation of liquid, but the water gun can not be shot into the liquid.
8. To prevent gas from accumulating in low recesses, use an exhaust fan to send the leaked gas to the open area.
9. People are prohibited from staying in low-lying or downwind areas.
