Ammonia what harm a human body. Ammonia has a strong irritant hazard after inhalation of the nose, throat and lung irritation causing coughing, shortness of breath and asthma; laryngeal edema may be due to suffocation; pulmonary edema can occur, causing death. Ammonia splash in the eyes, if not to take emergency measures to pure ammonia, can cause corneal ulcers, perforations, and further cause intraocular inflammation crash ammonia, resulting in ocular atrophy and blindness. II. 1. protective measures respiratory protection: its possible exposure to ammonia vapor, should wear protective masks. Emergency rescue or escape, it is recommended to wear self-contained breathing apparatus. 2. Eye protection: Wear protective chemical safety glasses. 3. protective clothing: wearing overalls. 4. Hand protection: Wear gloves against chemicals. 5. Other: work site prohibit smoking, eating and drinking. Ammonia plant after work, take a shower. To maintain good health habits.
