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. More articles from Allison Engineering Limited: |
