The application

A global leader in silicon-based technology and innovation had a recent incident at another site outside of the UK which forced it to look again at procedures for entering and monitoring analyser houses where oxygen depletion is a possibility.

Existing procedures were carried out using a portable O2 monitor on an individual basis.

The challenges:

  • * Portable monitors only alert the user to low oxygen when inside the analyser houses
  • * Not all operatives were carrying personal monitors
  • * Ideally, the site needed to be monitored in three zones individually and at two security offices.
  • * Due to the scattered nature of the analyser houses, a hard-wired solution was not feasible.
  • * The site was classified as Zone 1, therefore Atex approved equipment would have to be used.
Total Protection’s complete wireless solution including traffic lights from WERMA

Total Protection was able to provide a solution with the following key features:
* External display, remote sensor
* Wireless transmission of data
* Pre-wired/configured for self install
* Powered via 110v supply preferred
* Some sensors to monitor for H2 as well as O2
* Delivered within 12 week time frame
* Atex-approved traffic light system for access/entry signalisation

WERMA Products provide access/entry warning signals

The new compact range of EX-approved LED beacons in the 729/728 series provide extremely bright, long-lasting LED beacons as permanent or flashing lights to signal if it is safe to enter and work inside the analyser houses.

Mission accomplished

The Total Protection system was able to meet the criteria prescribed by the applications with the use of wireless technology being one of the most significant factors in enabling the complete system to be installed quickly, without costly infrastructure work.
