For the sake of the fire department, rooms where pressure bottles are being used have to be marked with a sign saying: Pressure bottles to be removed in case of fire
Pressure bottles should stand properly and be secured from tipping by a chain or similar.
Acetylene is used in laboratories in connection with AAS, and in workshops for welding. Working with acetylene bottles poses a particular risk, because when acetylene is heated, it can decompose by a self-catalytic reaction. The temperature in the bottle rises, and there is a risk of explosion.
The bottle can get heated due to flashback from the burner, and therefore, manometers for acetylene bottles should have a so-called check valve attached.
Should the accident occur, and the decomposing of acetylene begins, do as follows:
• Leave the room and evacuate the area
• Call the fire department
