Evacuation system - chemical plant

Problem statement.

The client was a chemical factory. Because this factory consists of several buildings, organising an evacuation was not straightforward. The system worked by having employees hang a tag indicating their presence in a designated spot when entering a building. In the event of an emergency, these tags would be taken to the evacuation point where it could be checked who might still be missing.

This could be improved. A system was therefore set up to make it possible to more quickly determine who was located where.

Intended goal.

The system must provide transparency so that it is always possible to see who is in which building. It must also be extremely simple for users to check in to a building. The system must also have the highest possible uptime.

Approach.

Transparency for the user was achieved by placing a screen at the entrance of each building showing a list of people currently inside. Additional safety-related information is also displayed, such as wind direction or the presence of first aid personnel.

To achieve the highest possible uptime, work was done on multiple levels.

Hardware:

A small SBC controller (Raspberry Pi) was chosen because these are easy to replace, are a standard solution, and are robust. The system has been running for over 10 years and the failure record has proven it was a good choice. The server was duplicated to prevent downtime there as well.

Software:

This was custom built, both the software on the endpoints and the server software. Tailored to the client’s needs.
Including:

  • Automatic server failover. The client can switch over if the primary server becomes unavailable.
  • Badge data is stored in the access control system. Should this fail, a backup is available to switch to, which holds the most recent attendance records.
