A chemical dispensing anti-burglary booby trap device is disclosed from which a chemical such as tear gas is discharged into the area to be protected when an intruder opens a window or opens a door or enters an unauthorized area with which the device is associated. The anti-burglary booby trap device employs a spring biased pressurized container for discharging a chemical from a pressurized container. A mechanical trigger for releasably retaining the pressurized container in a cocked position, an improved mechanical and electromechanical trigger to release the chemical, and a built-in safety to deactivate the device, which makes it virtually immpossible to accidentally discharge the device, are described.
