Behavior in case of a chemical accident

Ammonia

Colorless, corrosive gas lighter than air, with a sharp, irritating (sal ammoniac) smell. In the atmosphere, it forms a cold white fog cloud that stays on the ground. When warming, the gas cloud rises.
 

Dangers
Toxic chemical concentration in air.
 

Health effects
Extremely irritating to eyes and respiratory system. Causes tearing, nose irritation, sore throat, cough, difficulty in breathing, and chest pains. In case of higher concentrations, severe respiratory and lung damage, including pulmonary edema, may be sudden death. Corrosive ammonium hydroxide which damages the eyes and skin is produced by reacting with moisture.
 

Action
More perpendicular to the wind direction outside of the danger zone when you are outside. Hide in confined spaces. Close all doors, windows and ventilation openings in the rooms. Cover the airway, if possible with a damp cloth.
 

First aid
Move the injured to the uncontaminated area to fresh air, remove contaminated clothing, flush the skin and eyes with running water for 20-30 minutes. In case of breathing difficulties, administer oxygen. Ensure peace and warmth. As the symptoms may appear later, the injured will definitely need to be hospitalized!
