A safety device provides audible instructions for operation of a fire extinguisher. The device has a support for a fire extinguisher, a detector, e.g. a switch, for detecting when the fire extinguisher has been removed from the support, and an audio system for providing instructions on the use of the fire extinguisher. Preferably, the device has a visual sign with instructions for use of the fire extinguisher as well as the audio system for giving similar information. The audio system may have prerecorded messages and/or have recording means and play-back means to provide user-defined messages.
