Law and state regulations, in contrast to the above- mentioned, may also state that further fire-extinguishers, pieces of device, equipment and materials have to be employed.

Fire-extinguisher is a device which, when it is in working order, discharges the extinguishing agent controllably due to the pressure of released or generated propellant (gas).
Extinguishing agent is the fire-extinguisher’s load or the part of its load which is suitable for fire extinguishing.
Propellant is the part of the fire-extinguisher’s load which discharges the extinguishing agent of the device.
