Behavior in case of a chemical accident

Chlorine

Yellowish green corrosive gas is heavier than air with a sharp, irritating scent.
Dangers
Toxic chemical concentration in air.
Health effects
Extremely irritating to eyes and respiratory system. Causes tearing, irritation of eyes and throat, coughing, nausea, vomiting, headache, dizziness, and difficulty in breathing. In moist air, it also irritates the skin. Possible lung edema and death at higher concentrations.
Action
Move 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. Avoid staying in basements, as the gas is heavier than air, the gas cloud moves on the ground and can accumulate in low places. If possible, go to the upper floors.
First aid
Move the injured to the uncontaminated area to fresh air, remove contaminated clothing, flush the skin and eyes with running water at least for 15 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!
