Safety Instructions

Emergency summary: No gas, the cylinder container is easy to overpressure when heated, there is a risk of explosion. Frostbite is easily caused by direct contact with liquid ammonia. GHS hazard categories: According to the chemical classification, warning label and Warning specification series standards; The product is a compressed gas under pressure.
Warning word: Warning
Danger information: Gas under pressure, if heated can explode.
Precautions:
Precautions: Keep away from heat sources, open flames, and hot surfaces. No smoking in the workplace.
Accident response: cut off the leakage source, reasonable ventilation, accelerate diffusion.
Safe storage: Avoid sunlight and store in a well-ventilated place.
Disposal: This product or its container shall be disposed of in accordance with local regulations.
Physical and chemical hazards: no gas, the cylinder container is easy to overpressure when heated, and there is a risk of explosion. High concentration inhalation can cause suffocation.
Exposure to liquid ammonia can lead to frostbite.
Health hazard: the nitrogen content in the air is too high, so that the oxygen partial pressure of the inhaled gas drops, causing lack of asphyxia. When the concentration of nitrogen is not too high, the patient initially felt chest tightness, shortness of breath, and weakness. Then there is restlessness, extreme excitement, running, Shouting, trance, gait instability, called “nitrogen moet tincture”, can enter a coma or coma. In high concentrations, patients can quickly become unconscious and die from respiratory and cardiac arrest.

Environmental harm: No harm to the environment.
