Behavior in case of a chemical accident

Propane, butane

Colorless extremely flammable gas, heavier than air, to which strong-smelling substances have been added.
Radiating heat and smoke from the fire, overpressure and spill fragments arising from the bursting of tanks.
Health effects
In the case of non-combustible leakage, oxygen can be pushed out from confined spaces and cause headaches, drowsiness, loss of consciousness, burns due to heat radiation, and smoke-induced breathing difficulties, contusions caused by excessive pressure, and wounds caused by scattering shards.
More perpendicular to the wind direction outside of the danger zone when you are outside. Cover the airways. Close all doors, windows and ventilation openings in the rooms. 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!
First aid
The injured 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 to the doctor.
