Chemical Spills Early Warning Element and System

This article describes a simple and inexpensive chemical spill detector in an associated automatic warning system. The detector can be used in any location where chemicals are used and a spill can occur.

The detector 10 is illustrated in the figure. Two wires 12 and 14, which may be made of nickel or other suitable metals, are located in close proximity to each other and fastened within a folded strip of litmus paper 16. Upon proper placement of the wires 12 and 14, the litmus paper is folded and its edges glued together. This is the sensing/indicating cell. The cell is then placed in a packet consisting of a bottom layer 18 of absorbing paper and a top transparent window
20. Once more, the packet is sealed around the edges with glue.

In practice, several detectors can be placed on the floor and be connected together to an automated warning system shown as block 22. With this system, it is possible to identify chemical spills at an early stage by the increased conductivity between the wires 12 and 14 and by the changing color of the litmus paper 16.
