This solution is applicable to the liquid ammonia refrigerating system and the cold burst liquid ammonia (ammonia) in the company. Accidents and Rescue of Leakage, Fire and Explosion Ammonia Detector Ammonia Transmitter Ammonia Detector Ammonia Alarm Ammonia Probe Ammonia Probe Manufacturer Ammonia Probe Price Portable Ammonia Probe Ammonia Detection Unit Ammonia Alarm Device II. Types of Leakage and Harmfulness Analysis 1. Analysis of Hazard Characteristics of Ammonia 1) Physical and Chemical Properties of Liquid Ammonia: Ammonia is a colorless, transparent and irritant Odor of gas. Easily soluble in water, the aqueous solution is alkaline. Relative density 0.60 (air = 1). When ammonia gas is pressurized to 0.7-0.8 MPa, it becomes liquid ammonia, and a large amount of heat is released. On the contrary, liquid ammonia absorbs a large amount of heat when it evaporates, so ammonia can be used as a refrigerant, and contact with liquid ammonia can cause severe frostbite. Its inexpensive features are widely used in the ice-making and refrigeration industries.
2) Hazard categories: Class 2, 3 toxic gases, 8 corrosives. The fire and explosion danger category is Category B. When ammonia and air are mixed to a certain percentage, the explosion can be caused by an open flame. The explosion limit is 15.5-25%.
3) Ammonia has a high volumetric expansion coefficient. When the volume of liquid ammonia is in the range of 0-60°C and the temperature of liquid ammonia is increased by 1°C, the pressure of the liquid increases by 1.32-1.80MPa, thus the liquid ammonia. Overfilling the container can easily cause an explosion.

2. Hazard Analysis of Liquid Ammonia Leakage (1) Low concentration ammonia has irritating effect on mucous membranes. High concentrations of ammonia can cause tissue necrosis, chemical inflammation of the skin and upper respiratory mucosa, burns, pulmonary congestion, pulmonary edema and hemorrhage.
(2) Eye contact: Immediately lift the lid and rinse thoroughly with plenty of running water or saline solution for at least 15 minutes. Get medical attention.
(3) Inhalation: quickly leave the site to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Get medical attention.
(4) Mild poisoning: Eyes, mouth pungency, runny nose, cough, hoarseness, difficulty swallowing, dizziness, headache, conjunctival hyperemia, edema, lips and mouth, eye congestion, chest tightness and sternal area pain, etc. .
(5) Severe poisoning: Inhalation of high concentrations of ammonia can cause laryngeal edema, throat phlegm, and suffocation. Exposed skin may have a degree II chemical burn, eyelid, lips, nose, pharynx and laryngeal edema, mucosal erosion, may have ulcers.
(6) Environmental hazards. It is harmful to the environment, can cause pollution to the atmosphere and cause frostbite to animals and plants. Discharge of water to be dissolved, sent to the professional department to deal with.
3. Equipment parts that are prone to accidents (1) Vapor phase inlet/outlet of liquid ammonia storage tank, liquid phase inlet/outlet, sewage outlet, discharge buckle, liquid gauge excuse, pressure gauge excuse, etc. Take over, valve, flange connection, etc. Failure or leakage. (2) Ammonia piping flanges, valves, and flanges fail or leak seals;
(3) leakage or burst of hose for ammonia tanker loading and unloading;
(4) Ammonia cylinder leaks or explodes.
