It is unasafe for someone to work alone in an industrial environment. 
At times it is unavoidable.  I have been told of an electronic device
a person wears that if they are immobile for a few minutes it would
sound an alarm and call an emergency telephone number.  (This is NOT a
device that must have the operator push a button)

Where can I find such a device?

Smaye,

I found the following devices that activate an alarm and call an
emergency number when a person is immobile:
  
   
"Fall Detector" designed by the Tunstall Group (UK)
    
"What is a Fall Detector? 
  
The fall detector is a unique, miniature device designed by the Tunstall group. 
It can detect when the wearer has had a potentially serious fall and
triggers a call for help via a Tunstall home unit, to the Basildon
Careline Control Centre.
The device is very small and is light enough to be worn unobtrusively
and safely, on a belt or as a brooch.
  
How does it work? 
The Fall Detector utilises an intelligent two-stage detection process
in order to identify a genuine fall event.
First a mercury trip switch is triggered. The alarm then waits for
fifteen seconds in case it has been activated by mistake.
If after fifteen seconds it has not been returned to an upright
position it will send a call through to Careline's Control Centre."

Another alarm management system that activates an alarm and sends a
call when no motion is detected.
  
DSS DECT? Secury System with exact localisation
http://www.funktel.de/eng/product_dss.htm
  
  
"The new DSS DECT? Secury System is based on a modern multicellular
DECT? communication system. The system's use of multiple channels
guarantees all security functions, even with high traffic volumes. The
small and lightweight handsets offer a combination of forwardthinking
features: personal emergency signalling functions combined with
automatic localisation, complete telephone functions with all
modernISDN features, and comprehensive messaging functions for text
message transmission. The modern and ergonomic DECT? Secury FC1 S
handsets are small and robust, easy to handle and simple to operate.
...
The system localises and notifies cases of emergency. Monitoring and
voice links can be established and remote controlled between the
switchboard and the employee in danger.
Attack situations are signalled by means of a tear-off contact, and in
the event of accidents or attacks in a dangerous workplace environment
the call for assistance is made automatically via sensors, e.g. if the
person falls or loses consciousness.
The Secury FC1 S handset enables willdependent alarms to be triggered by
the user via the emergency signalling button, and will-independent
alarms such as position alarm, no-motion alarm, time alarm and loss
alarm."

The DSS DECT most closely fits what i was looking for although far
more than just a alarm for lack of motion.

Both of these are for Europe and from what I understand will not work
in USA.  Didn't you see anything from the States?

Thanks.

This actually looks closer to what I was looking for, except I see no
provision for it to call an emergency number in the event of an alarm.

This person will be working alone entirely.  no one will be there to
hear an alarm.  A call must be automatically made.  Some kind of auto
dialer system?

The "Fall Detector" is available in the United States through Health
Watch Inc. When no motion is detected for 15 seconds, the device
automatically sends an alarm signal to the HW900 console which
immediately contacts the Health Watch Response Center. A trained
operator answers the call, and if there is no response from the wearer
then emergency help is dispatched.
  
  
"Intelligent two-stage sensing technology 
  
Worn on a belt clip or in a pouch, our Fall Detector's intelligent
design provides accurate detection of a potentially serious fall by
using an intelligent two-stage detection process that minimizes false
alarms:

1.	The Fall Detector wakes from standby mode if its first sensor
detects a rapid change in a person's physical orientation. Its
activity indicator light turns green and it sounds an "early warning"
beep. Then, if its second sensor detects an impact from a fall, the
process continues. The green light flashes for 6 to 15 seconds while
the device monitors to verify if a fall has occurred.
  
2.	If the person's body position remains unchanged for up to 15
seconds, the light turns red and the device sounds four "beeps." This
means it has registered an emergency, and is sending an alarm signal
to the Response Center, providing reassurance for you that
professional help will be dispatched immediately."

I also came across these solutions:
  
  
iLife? Fall Detection Sensor
  
"The iLife? Fall Detection Sensor is a self contained, battery
operated, wireless fall sensor, worn on the body of the protected
person. It is designed to detect falls, abnormal body movements, or
extended periods of inactivity and automatically summon assistance
without end-user intervention.
The iLife? Fall Detection Sensor was developed to provide seamless
24-hour protection. The sensor and its wireless radio transmitter are
enclosed in an inconspicuous, attractive, wearable housing about the
size small ladies compact (only 2.25 inches high and 0.57 inches
thick). 
The iLife? Fall Detection Sensor's advanced design and operations have
been granted patents and are protected under United States and
international patent laws.
Unlike the current generation of emergency summoning devices, the
iLife? Fall Detection Sensor will AUTOMATICALLY call for help when
either a fall or an abnormal period of no motion/inactivity suggests
that an emergency condition exists."

Man-Down PowerCode? Transmitter
  
"The MDT-122 is a microprocessor-controlled "man-down" personal
emergency transmitter designed for use by guards and security officers
in prisons and institutions, or by people working alone in industrial
and other high-risk facilities."

Got the best answer from a fireman.

In the fire service, there are Personal Alert Safety System (PASS)
devices. These can be as complex as being hooked up to the air lines
of the SCOT Air Pack, or as basic as a hanging unit. The basic models
are about the size of a can of soda and have a very basic activation
switch. When the unit isn't moved for a period of time, say 60
seconds, it starts to chirp. If you were wearing one and it starting
doing this, you would just have to jiggle it a bit, or move your body.
If you wern't able to move it, the alarm would get very loud and, if
available, start flashing.

A link to the Super PASS II - this one is much like the ones on my fire department.
http://www.gracesales.com/products/superpass/


If you have any questions about them, go down to your local fire
department and ask them. They might have some older ones that don't
meet the new standards that they are willing to get rid of.


Best of luck

Casey

Just a note, the Tunstall fall detection device was tested in the U.K.
and found to have many false activations, the beep noise was faint and
hard to hear, and the reset time of 15 seconds was too short.
