Concentrate Control Supply (CCS) Systems

What’s different about your system compared to any fixed suppression system?

The difference is F-500 Encapsulator Agent.  Most fire suppression systems are designed to buy time until help arrives.  A CCS system with F-500 EA will extinguish your fire.  Foam systems will deluge foam everywhere, yet foam is not recommended for three-dimensional fires, and most fires are three-dimensional.  F-500 EA is an extra margin of safety.  It make every drop of water more effective.  Actually, the fire will go out faster than using plain water resulting in less damage.  In the case of Class B fuels, rubber, Class D metals or powder bulk granular, F-500 EA is definitely the preferred method for total extinguishment.

Does the F-500 EA go bad over time?

No.  F-500 EA has a shelf life of 15 years, however NFPA 25 (Chapter 11.1) states that any foam agents should be sample tested annually.

Will the F-500 EA corrode our system?

F-500 EA is noncorrosive to metal or rubber components.

Why would we spend the extra money for an agent added to our system?

We know water is not as efficient as F-500 EA in extinguishing a fire, so from our point of view every suppression system should use F-500 EA.  In some cases water simply can’t do the job.  Examples are Class B liquids, chemicals, combustible granulars, Class D metals, turbines and transformers.

Piercing Rod Systems

If we see any smoke, we’ll just call the fire department. Why would we need a piercing rod?

Hopefully you already have an Emergency Response Procedure prepared. If not, Hazard Control Technologies can help you prepare one designed for your plant. This procedure will involve training for your management, personnel and the local fire department. Without such training, the local fire department is not prepared to mitigate industrial fires. This can result in unnecessary loss of property and possible harm to personnel.

Part of being prepared is having the equipment necessary to extinguish potential hot spots or fires and training on how to use this equipment. A piercing rod is the only recommended way to extinguish deep-seated combustible bulk granular fires, like coal, rubber crumb, grain, sugar and more.

How deep can a piercing rod go?

Our piercing rod systems are sold with 5-foot Add-A-Section screw connection piping for 25, 50, 75 and 100 foot total lengths.

Why do we need F-500 EA? Can we just use water through the piercing rod?

With certain bulk solids, like coal, you cannot apply plain water without causing a dangerous flare-up. Such a flare-up can cause subsequent explosions. The addition of F-500 EA at 1% prevents flare-ups from occurring.

Additionally, F-500 EA reduces the surface tension of the water making the water droplets smaller and more able to penetrate through the coal. At the same time, the F-500 EA cools the hot spot, removing the heat that supports the fire.

How do you get it out after a piercing operation?

Sections of piercing rods are heavy.  After adding a few sections, the piercing rods become too heavy to remove manually, not to mention the tons of granular materials.  Generally, a Come-Along is attached to the lifting head during extraction.  After every five feet, a piece of the Add-A-Section is removed.

Is a piercing rod only used on coal hot spots?

Piercing rods can be used on any combustible granular or powder hot spots whether stored in a pile, silo or bunker.

F-500 EA Fire Extinguishers

What ratings does the F-500 EA extinguisher have?

The F-500 EA fire extinguisher is not UL Listed, however this does not mean it can’t be used in an industrial setting.  The F-500 EA fire extinguisher can mitigate small, incipient Class A and Class B polar and nonpolar fires and even render small fuel spills nonflammable and nonignitable.  The extinguisher could also be used on small Class D combustible metal fires.

Can it be recharged?

Yes.  A 10-ounce bottle of F-500 EA provides a 3% solution, when mixed with 2 ½ gallons of water.  The head assembly is re-attached and the unit is charged to 100 psi with a standard air chuck used for filling tires.  The refilling procedure is quick, inexpensive and simple.

How long do they last during a fire?

The discharge time is only a couple of minutes.  Knowing this, you must attack a fire quickly and efficiently.  F-500 EA has excellent burnback resistance, so once you have extinguished a portion of the fire, move on.  It is unlikely the fire would reignite.

Do they have to be inspected?

Yes.  All fire extinguishers must be inspected annually for pressure, volume (by weight) and visually checked for serviceability.  Every five years, the extinguisher must be hydrostatically tested.

Portable Carts

What are they used for?

F-500 EA Portable Carts carry F-500 EA concentrate and have an onboard eductor that you can set at 1% for Class A fires and 3% for Class B or D fires. Portable carts have wheels, but because they are heavy, their use would probably be limited to factory floors, parking lots or areas with sidewalk access.  They would be ideal for a manufacturing setting such as a tire recycling facility, wood mill, chemical plant or fueling yard where water is available in various locations.

How long can they extinguish a fire?

The 26-gallon Portable Cart will extinguish a Class A fire for about 43 minutes at 1% and a Class B fire or fuel spill for 14 minutes at 3%.  The 40-gallon Portable Cart has greater capacity and can extinguish a Class A fire for 66 minutes and a Class B fire or spill for 21 minutes.  Keep in mind, it is rare that any fire takes more than a few minutes to extinguish with F-500 EA and even so, the unit will continue to flow water.


Where would you use a HandyPack?

Handy Packs are excellent for first responders for almost any type of Class A or B fires.

How long can they deploy?

The 2 1/2-gallon Handy Pack will extinguish a Class A fire for about 12 minutes at 1% and a Class B fire or fuel spill for 4.1 minutes at 3%.  The 5-gallon Handy Pack has greater capacity and can extinguish a Class A fire for 25 minutes and a Class B fire or spill for 8 minutes.  Keep in mind, it is rare that any fire takes more than a few minutes to extinguish with F-500 EA and even so, the unit will continue to flow water.

FLIR Thermal Imaging Cameras

How do they see through walls?

The FLIR thermal imaging cameras do not see through walls.  In fact, they are reading the surface temperature of the vessel.  What they do see is an anomaly of heat, proving that higher temperatures are inside the vessel.

We know there’s a fire why do we care how hot it is?

For our purposes, it is not as important to know the exact temperature of a hot spot as it is to know where the hot spot is located.  Generally, with a steel silo, you can add 100°F to estimate the real temperature inside the silo.  We do however try to estimate the temperature to know at what stage the fire is.  In the example of coal, it can take days of smoldering to cause a collapse.  As the coal fills the void, combustible dust is created, leading to an explosion.  Knowing that the coal is approaching 450°F means the situation is very dangerous.

We have a pyrometer, why do we need a thermal imaging camera?

A pyrometer can identify the temperature and locate a hot spot, but a pyrometer can’t provide a picture of the actual hot spot.  Some FLIR models can provide a video of the hot spot and a picture of the infrared temperature, as well as an identical picture as the eye sees it.  This is a good record of where you were in the plant when you read the anomaly.  FLIR cameras also have other adjustments to make readings more accurate and useful.
