Other foam systems are tested by the original foam system manufacturer on a test bench, not on the fire truck itself. This means there is a chance of inaccuracies as the foam system is used, costing departments money every year on a foam system that is too lean or rich. Choosing to purchase a foam fire suppression system from a single-source supplier offers fire departments many additional benefits.
All the parts and pieces contained within the system come from one supplier, which means that it is easier to obtain replacement parts and provide system service if needed. In addition, there is no middle-man markup, resulting in a cost-effective foam system option for fire departments.
Lastly, Pierce does not sell its proprietary foam system to any other fire apparatus manufacturers, which means Pierce can control quality testing and standards. Below are some key differences between the two that your fire department should consider in the selection process.

Fighting fires is challenging, demanding work, but with an addition of a foam system to emergency operations, fire departments can save time, money and resources with a more effective means to combat fire.

Topics: Products. Products include custom and commercial pumpers, aerials, rescue trucks, wildland trucks, mini pumpers, elliptical tankers, and homeland security apparatus.
In addition, Pierce designs its own foam systems and was the first company to introduce frontal airbags and the Side Roll Protection system to fire apparatus.

The chemical composition of foam helps break down water surface tension, allowing water to penetrate burning materials, and thus, making water work more efficiently.
Reduce the amount of water required to fight fires. The use of foam extends the usable amount of water on the apparatus. For fire departments without mutual aid or easy access to fire hydrants, the use of foam is beneficial because it means fire fighters can use less water to put out a fire. A foam system is especially beneficial to rural and wildland fire departments, where access to a replenishing water source is not always possible.
Cling to burning materials. The total amount of Class B foam reported was 40, gallons. The survey results were used to develop a statewide solution for collecting and disposing of most of the Class B foam so it no longer poses a threat to the environment. Not all Class B foam will be collected and disposed because:.
The collection and disposal efforts officially started on December 12, , with a kick-off press conference and an initial pick-up at the Lansing Fire Department. Read the January 3, collection and disposal letter. This is a recording of a webinar held to discuss the AFFF pickup and disposal program and how communities could participate in the program. The webinar was intended for municipal and regional government officials, wastewater managers and directors, landfill owners and operators; operations and maintenance personnel, scientists, product and service providers; project managers and engineers, environmental consultants, water advocacy organizations, environmental and community groups, and anyone interested in PFAS impacts in the Great Lakes region.
Callers to the toll-free PEAS line are asked if Class B foam was used at the fire or explosion or spill to determine if response actions are needed. Browsers that can not handle javascript will not be able to access some features of this site.
There are specially designed training foams available from most foam manufacturers that simulate AFFF during live training, but do not contain flourosurfactants like PFC. These training foams are normally biodegradable and have minimal environmental impact; they can also be safely sent to the local wastewater treatment plant for processing.
The absence of flourosurfactants in training foam means that those foams have a reduced burn-back resistance.
For example, the training foam will provide an initial vapor barrier in a flammable liquids fire resulting in extinguishment, but that foam blanket will quickly break down. That's a good thing from an instructor's point of view as it means you can conduct more training scenarios because you and your students are not waiting for the training simulator to become burn ready again.
Training exercises, particularly those using real finished foam, should include provisions for the collection of spent foam. At a minimum, fire training facilities should have the ability to collect the foam solution used in training scenarios for discharge to a wastewater treatment facility. Prior to that discharge, the wastewater treatment facility should be notified and permission granted to the fire department for the agent to be released at a prescribed rate.
Surely the developments in induction systems for Class A foam and perhaps the agent chemistry will continue to advance as it has over the past decade.
But as for Class B foam concentrates, agent chemistry development efforts seem to have been frozen in time with reliance on existing base technologies. Only since the introduction of environmental regulations during the past decade or so on fluorine-based AFFFs have the firefighting foam manufacturers taken the development challenge seriously. Some of these fluorine-free products are first-generation and others second or third generation.
They will continue to evolve in both agent chemistry and firefighting performance with the goal of achieving high performance on flammable and combustible liquids, improved burn-back resistance for firefighter safety and provide for many additional years of shelf life over foams derived from protein.
