Visual detection of spray-outs
January 1st 2008

Immediate, visual detection of dangerous spray-outs in critical areas in process systems such as pipe flanges, valves, weld sites and sample ports is the main benefit behind the development of On- Guard, an acid alert paint.

Introduced in the UK by Allison Engineering, On-Guard is a modified alkyd acid indicating paint which has been formulated and patented for industrial applications.

The early warning of the potential dangers resulting from leaks ensures important protection for employees, expensive process equipment and the environment.

On-Guard is applied like any other exterior paint product to 4mm dry thickness, which equates to two to three brush strokes, using a brush or roller.

Should acids or acid vapours pH3 or below escape, On-Guard will instantly change colour from its golden yellow to a vibrant red, alerting operatives to the potential dangers.
