Ground-based water-enhancer application for debris-pile burning – A case study in the Calgary Forest Area
Debris piles were scattered among a fuel-treated stand at the Jumpingpound Demonstration Forest. The existing trees were deemed as assets worth protecting while the piles required to be burned. To facilitate the protection of the trees surrounding these debris piles, the Calgary Forest Area requested the use of water-enhancer capable fire engines to protect the trees during debris pile burning. A total of 15 debris piles of varying fuel loads were burned over two days. The use of water enhancer capable fire engines allowed FPInnovations to document the use of suppressants (water and water-enhancer) to better understand their advantages and limitations.
Qualitative observations suggested that water-enhancers were more effective at withstanding radiant heat than water when applied immediately prior to the incident heat. Its efficacy, however, was found to decline with time.
