The intrinsically safe TPASS 3 motion-sensing man-down device from Grace Industries helps protect workers during confined-space entry. It has an audible out-of-range indicator, and workers have the option of deploying a range-extending micro-repeater. The portable work site alarm is placed at the confined-space entry point. The confined-space attendant carries the monitor. The confined-space worker’s unit automatically transmits a direct wireless alarm upon lack of motion or by manual activation to the portable work site alarm and to the attendant. A +100 dBA siren and intense strobe light are activated, while the attendant receives the alarm indicating which worker is in alarm. The device can also transmit an evacuation signal to the confined-space worker. 724/962-9231; www.graceindustries.com.
