area, determine the root cause of the ex- posure, and eliminate the hazard before a potentially tragic incident occurs.
The iAssign Beacons can be deployed and function anywhere—inside or out, hazardous location or safe zone. If access to line power is not available, it doesn’t mat- ter. The beacons are low cost, rated for any Class I area, are weather resistant, and op- erate up to four years on two AA batteries. They can provide location accuracy down to 1 meter, depending on the settings and number of beacons deployed, without the need for a GPS receiver or a complex trian- gulation algorithm and other costly wire- less infrastructure.
Using Beacons for Access Control
Location tagging isn’t the only function the beacons provide. Beacons can be used in conjunction with the gas detector to control access to a particular area. Based on settings and access level of the user as- signed to the instrument, when in prox- imity of a beacon marking a designated

area, the beacon can trigger the instru- ment to alarm and display a message to its user that they are in an area with “AC- CESS RESTRICTED.” They can also be used to activate or deactivate particular instrument functions, control settings, or send a message that other particular safety equipment is required to be used in a given area.
Data that tells you the “what” and the “when” without telling you the “where”
leaves you wandering in the dark and un- able to determine the why of any event. Beaconing shines light on your data and allows you to recognize the full value of the data that your gas monitoring program can provide.

Drive Your Future Safety Program from the Past
Education for Safety Professionals
Sharpen your safety skills with this Intermediate Level training course.
April 13, 2017
1 p.m. Eastern • 12 noon Central • 10 a.m. Pacific
This session is about using the past to drive your future. Back to the Future is impossible ... or is it? Do we rely on past performance to predict the future? Before you answer, ask yourself if you verified the safety performance of the last vehicle you rode in. For most of us, we trusted that it would be safe. The question is then, why did we place our trust in this certain uncertainty?
Join us as we decode the secret and demonstrate how you and the organization can leverage this phenomenon to build superior performing teams and safety programs... from the past. Registrants will receive a Certificate of Completion and can print the presentation slides in their entirety. Register now for this live, 90-minute presentation. Only $99 per attendee!
