Body Alarm Goes Off If You Stop Moving
"It's a great idea for farmers working in grain bins, silos, hog pits, or with chemicals or anhydrous ammonia," says Mike Nelson, U.S. distributor for the new Racal "body alarm" that senses body movement and sets off a 98 decible screech if your body stops moving for 20 sec. or more.
Nelson, who is also national distributor of Racal's well-known Airstream dust helmets, says the alarm lets other workers and family members take quick action if some-one wearing the alarm is overcome or gets stuck while in a confined working area. If the 9-oz. unit, which clips to a belt, detects no motion for 20 sec., it sets off a quiet 7 sec. pre-alarm. The wearer can then keep the alarm from sounding by simply moving or tapping the unit. If there's still no movement by the wearer after 7 sec., the alarm sets off its clear, strong siren.
The unit is dust and waterproof. A large switch on top, which can be moved with a gloved hand, turns the unit on or off as needed. It's powered by a single 9-volt battery. Sells for $149.
