Ammonia water, also known as ammonia water, has the chemical formula NH ∝· H ₂ 0 and a chemical quantity of 35.045. It is an aqueous solution of ammonia, colorless, transparent, and has a pungent odor. The melting point of ammonia is 77.773 ℃, the boiling point is 33.34 ℃, and the density is 0.91g/cm ³. Ammonia is easily soluble in water and ethanol. Easy to evaporate, with some alkaline properties, ammonia water is produced by passing ammonia gas into water. Ammonia is toxic, irritating and corrosive to the eyes, nose, and skin, and can cause suffocation. The maximum allowable concentration in the air is 30mg/m3. Mainly used as fertilizer.

Hazard Overview

Invasion route: inhalation, ingestion

Health hazards: Inhalation can cause irritation to the nose, throat, and lungs, leading to coughing, shortness of breath, and asthma; May suffocate and die due to laryngeal edema; Pulmonary edema can occur, leading to death. Ammonia water splashing into the eyes can cause serious damage, even leading to blindness, and skin contact can cause burns. Chronic effects: Repeated exposure to low concentrations can cause bronchitis. Repeated skin contact can cause dermatitis, characterized by dryness, itching, and redness of the skin. If there are wounds on the body's skin, be sure to avoid contact with the wound to prevent infection.

First aid measures

Skin contact: Immediately rinse with water for at least 15 minutes. If there are burns, seek medical treatment. For small amounts of skin contact, avoid spreading the substance over a larger area. Pay attention to keeping the patient warm and quiet.

Eye contact: Immediately lift the eyelids and rinse with flowing water or saline solution for at least 15 minutes. Or rinse with a 3% boric acid solution. Seek immediate medical attention.

Inhalation: Quickly leave the scene and move to a place with fresh air. Keep the respiratory tract unobstructed. Administer oxygen when experiencing difficulty breathing. When breathing stops, immediately perform artificial respiration. Seek medical attention. If the patient ingests or inhales the substance, do not perform mouth to mouth artificial respiration. A small one-way valve respirator or other appropriate medical respirator can be used. Remove and isolate contaminated clothing and shoes.

Ingestion: If ingested by mistake, rinse mouth immediately and take diluted vinegar or lemon juice orally. Seek medical attention. Inhalation, ingestion, or skin contact with this substance can cause delayed reactions. Ensure that medical personnel understand the personal protective knowledge related to the substance and pay attention to self-protection.

Storage precautions

Store in a cool, dry, and well ventilated place. Stay away from sources of fire and heat. Protect from direct sunlight. Keep the container sealed. It should be stored separately from acids, metal powders, etc. Outdoor storage tanks should have cooling measures in summer. Attention should be paid to personal protection during packaging and handling operations. Handle with care during transportation to prevent damage to packaging and containers.
