Poisoning symptoms

liquid ammonia

1 suction

Inhalation is the main way of contact. The stimulation of ammonia is a reliable and harmful concentration alarm signal. However, due to the smell of fatigue, long-term exposure to low concentrations of ammonia will be difficult to detect.

(1) mild inhalation of ammonia poisoning showed rhinitis, pharyngitis, bronchitis, bronchitis. Patients with pharyngeal pain, cough, sputum or hemoptysis, chest tightness and chest pain.

(2) the occurrence of acute inhalation of ammonia poisoning is caused by accidents such as pipeline rupture, valve burst and so on. The main manifestations of acute ammonia poisoning are respiratory irritation and burns. The symptoms were different according to the concentration of ammonia, the time of inhalation and the individual's perception.

(3) severe inhalation poisoning can appear laryngeal edema, subglottic stenosis and respiratory mucosa shedding can cause airway obstruction, caused by suffocation. Inhalation of high concentration can directly affect pulmonary capillary permeability and cause pulmonary edema.

2 skin and eye contact

On the low concentration of ammonia and wet skin can quickly stimulate. Wet skin or eye contact with high concentrations of ammonia can cause severe chemical burns.

Skin contact can cause severe pain and burn, and can produce coffee like color. By the corrosion rubbery and weak, the depth of tissue damage can occur.

High concentration of steam on the eyes have a strong irritant, can cause pain and burns, resulting in obvious inflammation and may be edema, epithelial tissue damage, corneal opacity and iris inflammation. Mild cases will ease, severe cases may be prolonged, and the occurrence of persistent edema, permanent scars, eyes bulging, opacity, cataract, eyelid and eyeball adhesions and complications such as blindness. Repeated or prolonged exposure to ammonia can lead to conjunctivitis.
