High expansion foam systems offer excellent fire protection
for liquids that are flammable or combustible, aircraft hangars, and areas
where storage is piled high.
How Foam Fire
Protection Systems Work
When foam concentrate, water, and air are mixed at the right
ratio, they create high expansion foam systems that offer maximum fire
protection. This foam creates a blanket that smothers the flame while
suppressing potentially hazardous or flammable vapours. The foam also cools the
flame and any metal surfaces in the area.
The key difference for foam systems is how the foam expands. The
higher the expansion rate, the more foam you create from a litre of foam
solution. For example, a low expansion foam gives you an expansion rate between
two to one and 20 to one. A high expansion foam has an expansion rate that
exceeds 200 to one.
A high expansion foam system uses a high expansion foam
generator. This is a water-powered fan that forces the foam to expand by
pushing it through a screen.
Find Out if a High
Expansion Foam Fire Protection System is Right for You
High expansion foam systems work for a vast variety of
different business areas. They work well if you have a large enclosed space
that will need to be filled quickly. This is why you often find high expansion
foam systems in areas with highly flammable liquids and gases or in hangars,
where a simple sprinkler system may not be enough to prevent disaster.
Places that store flammable liquid in outside storage or a
warehouse can benefit from a foam system, as can both truck and rail flammable
liquid loading racks. Foam fire protection systems are also commonly found in
aircraft hangars, petrochemical-related businesses, and the oil and gas
Loading facilities and large warehouses also benefit from
the flexibility of a high expansion foam system for fire protection. This is
especially true if the storage area is piled high. A large open area allows a
fire to spread quickly and if there is a large amount of merchandise in the
area, it provides even more surfaces to help the fire spread quickly.
When you choose a high expansion foam system for fire
protection, it’s important to choose the right company to install your system.
Experience is important since your system needs to conform to industry
standards while providing maximum protection for your business. Consider an
industry leader, such as CrownFire, that will include a hazard analysis,
training, equipment, management, and scheduling in their customized fire
Along with consulting with the local fire jurisdiction and
the insurance underwriter, CrownFire goes a step further by analyzing the
location’s specific environmental and physical conditions and how those will
impact how a fire will behave in the area. Fire protection isn’t a
one-size-fits-all situation so it’s important to find the right consultant for
your business’s unique fire protection needs. It’s key to consult with an
experienced company that has a proven track record saving both property and
If you work with flammable or combustible materials or have
a large open area, consider high expansion foam systems for fast fire
