can light chemical protective clothing be used in liquid ammonia occasions

1 believe most people in the refrigeration industry or chemical industry know the harm of liquid ammonia. Today, let’s analyze a problem that many people are concerned about: can light chemical protective clothing be used in liquid ammonia occasions

liquid ammonia, also known as anhydrous ammonia, is a colorless liquid with strong pungent smell. 1t is very soluble in water. Generally, liquid ammonia can be used as a refrigerant. Contact with liquid ammonia can cause severe frostbite. Ammonia is an important chemical raw material. 1t is mainly used in the production of nitric acid, urea and other fertilizers. 1t can also be used as raw materials for medicine and pesticides. Liquid ammonia can also be used as booster for rocket and missile manufacturing

liquid ammonia is corrosive and easy to volatilize, so its chemical accident rate is quite high. Mild inhalation of ammonia poisoning can be manifested as rhinitis, pharyngitis, tracheitis, etc., patients with pharyngeal burning pain, cough, expectoration or hemoptysis, chest tightness and sternal pain. Acute ammonia poisoning can be manifested as irritation and burn of respiratory tract mucosa. Severe may appear laryngeal edema, respiratory tract mucosa off and other consequences

low concentration of ammonia can quickly stimulate the eyes and moist skin. Wet skin or eyes exposed to high concentrations of ammonia can cause severe chemical burns

skin contact can cause severe pain, burns and coffee like coloring. The corroded part is gelatinous and soft, which can cause deep tissue damage

the above is an introduction to the performance of liquid ammonia and its harm to human body. Compared with the respiratory system, the positive pressure air respirator and other respiratory protective equipment must be equipped when working in liquid ammonia. 1n view of the corrosion performance of skin, it is recommended to equip with chemical protective clothing, preferably heavy-duty fully enclosed chemical protective clothing, because light-duty semi enclosed chemical protective clothing can prevent the face from being exposed, and the protective effect is not so good. 1n order to avoid liquid ammonia or ammonia eroding the exposed skin, it is better to choose heavy-duty fully enclosed chemical protective clothing as much as possible
