Inland’s Guard is an under-grate drain block valve designed to prevent liquids from reaching stormwater systems. It is used to contain spent aircraft deicing fluid and fuels. The Guard is robust and easy to operate. Because of its unique design, it is virtually impervious to freezing. Under normal conditions, the Guard is opened for uninterrupted stormwater flow. In the event of a spill – or as a preventative containment measure - the valve can be sealed within seconds. For more information visit www.inlandgroup.ca/glycolguard.php.
