composite HAZMAT exercise (edited)




Rutgers School of Public Health saw a need to improve their training on hazardous materials (Explosive, Radiation, Oxygen depletion, etc) to include outside life simulations of hazardous incidents. They approached S&A Technologies to team up and develop a smartphone based sensor simulation. Together they received a grant from NIEHS to develop a prototype for this application.


Beacons should simulate hazardous spills and be able to communicate with any smartphones. A web application should configure the beacons for various types of simulated spills and connect them with their beacons. The smartphone app will show any spill in the neighborhood and show readings of a simulated sensor.


S&A was confronted with a set of challenges that needed to be overcome. The whole system had to be based on existing and available technologies. A wide variety of expertise was needed (Networking, Android development, Web Server development, subject matter expertise)


S&A Technologies studied available beacon products and settled on an inexpensive bluetooth beacon. S&A developed a rapid prototype on the web with a graphical interface of a simulated spill site. S&A developed a android app that communications with the beacons and with the database at the same time. Initial field tests were successful from the beginning.

Results: S&A Technologies has developed a fully functional prototype that has already been used in classes at Rutger’s School of Public Health.
