Behaviour in case of a chemical accident
Colourless extremely flammable gas, heavier than air, to which strong-smelling substances have been added.
Thermal radiation and smoke from fires, overpressure and shrapnel from the bursting of tanks.
In the case of a non-combustible leakage, oxygen can be pushed out from confined spaces and cause headaches, drowsiness, loss of consciousness, burns due to thermal radiation, and smoke-induced breathing difficulties, contusions caused by excessive pressure, and wounds caused by scattering shrapnel.
If you are outside, move perpendicular to the direction of the wind outside of the danger zone. Cover the airways. If you are inside, close all doors, windows, and ventilation openings. 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. Avoid sparks!
The injured person must be taken to a safe place and laid down on the abdomen. In case of flame burns, extinguish the clothing with the help of a blanket or a carpet and start cooling quickly.
Use cool water for cooling. After cooling, cover the damaged area with a clean sheet. Take the injured person to the doctor.
