Barricade International President, John Bartlett is the Florida firefighter who invented the first fire blocking gel after observing that a used, wet disposable baby diaper did not burn during a routine trash fire. From this humble beginning, he has brought us an easy-to-use system that is changing the way homeowners protect their most precious possessions and lifestyles. And professional firefighters have a highly effective tool for protecting the towns and homes threatened by wildfires.
