A method and arrangement for remotely stopping powered equipment in emergency situations. Embodiments of the invention include wearable radio remote transmitters ( 400 ) capable of transmitting a signal ( 500, 505 ) to powered equipment in the immediate area. A transmitter ( 400 ) desirably is located such that it can be quickly activated by the person wearing the transmitter, and may be equipped with a shock detection device capable of automatically activating the radio transmitter Powered equipment operating in the vicinity of transmitter-equipped personnel are fitted with receivers, electronics, actuator, batteries and/or electrical connections, as needed, to shutdown the equipment upon receiving a radio signal from a transmitter Sometimes receivers and amplifiers are located such that a transmitter's signal sent from any location in the area will reach all relevant equipment receivers with sufficient energy to activate the shutdown procedure. A preferred embodiment may include a manually activated transmitter ( 400 ) attached to a person's clothing and receivers and actuators mounted on all powered equipment within line-of-sight of this person.
