What should I do if high-purity nitrogen leaks?
When understanding the solution in the case of liquid nitrogen leakage, let's first understand some of the symptoms of inhaled nitrogen: when the concentration of inhaled nitrogen is not too high, the patient initially feels chest tightness, shortness of breath, weakness; This is followed by irritability, extreme excitement, running around, shouting, trance, and unsteady gait, which is called "nitrogen tincture", and can enter a state of lethargy or coma. When inhaled at high concentrations, patients can quickly fall unconscious, die due to respiratory and cardiac arrest. Let's take a look at how to deal with it.
1. Quickly evacuate personnel from the leakage and pollution area to the upwind, and set up an isolation area to strictly restrict access and access.
2. Notify the fire department and related units.
3. Emergency response personnel wear self-contained positive pressure respirators, cold-proof clothing, and cold-proof gloves.
4. Avoid leaking liquid into the basement or other enclosed manned workspace, and notify the relevant departments immediately if it cannot be avoided.
5. Do not come into direct contact with leakage.
6. Cut off the source of leakage as much as possible.
7. You can use mist water spray to accelerate the evaporation of liquid, but do not make the water gun shoot into the liquid.
8. Prevent the accumulation of gas in the low recess, and use the exhaust fan to send the leaked air to the open place.
