The struggle within. A constant battle between conviction and complacency.

The struggle within. Seeking illumination on what is to come, abhorred by the stranger I used to be.

The struggle within. Conscious of how I am perceived, versus how I desire to be seen.

The victory within, for I shall never surrender, to the struggle within.

 

We are all swimming in the same water. Many allow the slow moving current to waft them across waters surface to a destination, easily, and worry free. But they, will never make a splash.

A few will go against the current. Staring in the face of the rapids and enthusiastically welcoming the challenge. We will try. We may fail. Yet we try again. Maintaining determination and perseverance, allowing all apathy to wash away.

Who dared to go against the current succeed, as their will brought them there, even if it places them just out of reach of the goal. The triumph is yours, as all who dared to pull you under are washed away. They lacked the strength to go against the current.

“Be the best you, that you can be!”

No one fire department has all the answers, but all the fire departments may give the best answer to your question.

We can all learn from each other. The smallest rural department to the largest urban. Each of us have strengths and weaknesses. Only our attitudes make us different, when we choose not to learn best practices from all.

Be the best you, so your department can be its best, so we all can give our best to them; the community we each serve.

A civilians guide to saving lives & property.

The newest training module we have put together is a targeted piece for members of the community. This focuses on closing the door! Please share this with friends and family members.

In this final installment we will look at the branch piping and sprinkler heads in the wet pipe system. This piping is designed and arranged in a specific pattern, based upon its intended function. For example, a storage facility may have long runs of piping with heads arranged in rows. This design will provide fire control for the area. Think of this as the default design. A large open space could change configurations over the structures lifetime, hopefully, the piping and head configuration will match the needs. Many times these systems are fire suppression systems.

“Fire control is the method of decreasing temperature of fire gases and pre-wetting combustibles, keeping the fire in check.”

“Fire suppression sharply reduces temperature and directs water application onto burning materials which prevents re-growth.”

At a glance these may appear to be the same thing, but when it comes to the design of fire protection systems they are dramatically different. For more details the two types please refer to – http://firetrainingtoolbox.com/convsup.pdf

The piping that used is typically the same grade as the riser piping just much smaller in diameter. These lines should also be secured with “bomb proof” hangers. Attached to these lines are the sprinkler heads.

Sprinkler heads come in a wide variety of types and temperature ratings. Their orientation can be concealed, flush, upright, pendant, recessed, and sidewall. Just a few of the designs include open, early supression-fast repsonse, control mode, spray, and standard. We then get into the method of activation. Common ways are frangile bulb and fusible links. These will break or fuse at their designed temperature to allow the flow of water to occur.

As an engine company your role may be to support the system. Keeping the system filled with water and at the proper pressure can be paramount during a fire. Do not stop supporting the system until directed by Incident Command.

With knowledge and training an operation, that includes an activation of the Fire Protection system, will be mitigated with confidence and rigor. Fire Protection systems will become a powerful allie for those who understand there operation!

OPERATIONAL CRITICAL THINKING

Download as a poster

Strategical Guidelines – Department SOGS provide a baseline for operations line personnel will encounter. They are not hard rules that must be followed step by  step for each event. Company Officers and Incident Commanders are well versed in the SOGS, and have the fortitude that allows for deviation when required.

Tactical Patience – Incident Commanders and line personnel exercise tactical reserve, and perform only the tasks needed for the current operation. We stay diligent, maintaining a focus on task completion. Rigid processes of “checkbox firefighting” can set crews up for failure. Our strategical and tactical playbook is well written and versed, with the ability to call an “audible” when the incident dictates. Provide protection for lives in harms way, maintain crew integrity and complete the task in order of priority.

Crew Resource Management – Personnel performing the work will be supplied with all the necessary tools, equipment and support to complete the task. The Command Staff is there to support the work, and the line workers. Additional resources will be available when required for relief. Assignment of crews should only occur when a task is required to be completed. We must understand, “not everyone will get to play.”

Training for Operational Excellence – All members receive appropriate and timely training for the tasks they are expected to perform. Training will also include situations for critical thinking. Our baseline SOGS provide the framework for functional effort, however alert, “heads up firefighting” using critical thinking is required for operational excellence. Training complacency is training for failure.

After the isolation valve and clapper is the Riser pipe. The riser has one purpose, deliver water to the branch lines. A few discussion points can be made about the riser.

The riser makes “the water rise up!’
  • Depending on the pipes diameter it should meet Schedule 5, 10,  30 or 40.
  • Above ground piping should be ANSI, UL and FM approved materials.
  • Piping is hung with approved hangers to what we like to call “bomb proof anchors.”  Meaning if a bomb went off would that still be standing?
  • A visual inspection shall be performed regularly to check for damage including holes, friction damage and other  types of physical damage.

An intergral component of the system.

 

The riser pipe is a simple yet intergal compenent of the Wet Pipe Fire Protection system. This pipe directs the flow of water up to the ceiling level where it connects with main lines which in turn connect to the branch lines. The next post will focus on these other lines as well as sprinkler heads.

For more on Sprinkler Systems make sure to read NFPA 13.

Fire Protection Systems come in variety of forms depending on the application of how and what they will protect. When focused on water systems, we still have a few options. The most common is the Wet Pipe system, which consists of a water source, valve & associated piping, riser, branch lines and closed sprinkler heads. These systems are very simple and reliable. Today will focus on the valve in the wet pipe system.

Two parts make up this section of a wet system, the isolation valve and the clapper. The isolation valve performs just what the name implies, isolates the associated riser from the water source or header. This may be a Outside, Stem & Yoke (OS&Y) or a butterfly valve. The OS&Y is easily identifiable with its long threaded stem that should be fully visible when the valve is opened. If you do not see the stem, then the valve is closed and during pre-planning ensure to ask why. The butterfly valve will have a smaller handwheel and a “flag” should identify the position of the valve. When the flag is vertical or up & down, the valve is open. When horizontal or “side to side” the valve is closed.

Many shapes and sizes of clapper valves can be found in todays systems. A clapper or check valve controls the flow of water. This ensures that the system main and branch piping maintains water pressure, so that the heads actuate properly when needed. If the pressure below the clapper increases and opens the valve, then excess pressure is realeased through the retard chamber. We will cover that on another day.

Below you will find examples of valves that you may encounter. Remember, there are two main elements to the Wet Pipe System valve, the isolation valve and the clapper.

Having access to systems valves is critical.

Over the next several weeks I will be posting about Fire Protection Systems. The hope is we all can gain a better understanding of what is out there, the benefits of and our role in water suppression/control systems.

This picture is of a large commercial building of Non-Combustible construction. As you can see here they have three (3) sprinkler systems, a water flow alarm, fire department connection and a hydrant. What does this picture tell you?

 

Exterior views can tell you information of the type of system this building has.

If you need to enlarge this image to see the elements please click the image.

The first element we see is the hydrant in the foreground. Based on its proximity to the building, is it part of the public or private system? If it is public, then this is a great hydrant to use when supporting the system. However, if its part of the private ring header, will you only be taking available water away from the risers?

The next element we see are the three Wall Post Indicator Valves (Wall PIV). Each one of these hand wheels controls the main valve for each one of the sprinkler risers. They all protect different areas of the structure, yet are still in close proximity to each other. If more systems are needed they will install them closer to the area they are designed to protect. Only close the valve required and only when directed by the IC. We also see that these are locked with a chain. Do not cut the lock! Cut a link in the chain. Once the key holder arrives we can reuse the chain and secure it with the same lock. Little things like this provide great customer service.

The Fire Department connection also stands out. You will want to investigate this further as not all FDC’s are equal. A FDC may be sprinklers only, standpipes only or both. The cap, a label or another sign should indicate what the connection is for. If no indication exsist, contact the grounds manager ASAP during the pre-planning phase to have this corrected.

The final element we see is the water flow alarm, in this case a bell or gong. If/when the system actuates the flowing water will cause this alarm to sound. Depending on how it is set up, several actions may occur. The alarm may only be local, indicating a system is flowing and will the give the general area. The water flow may initiate a global alarm telling everyone in that building to exit. This may also be tied into a system that initiates a fire department response.

Knowing and understanding fire protection systems enables you to set up, control and manage an operation at an incident with a system. The owner of the building felt that the contents were worthy of installing the system so we should honor that decision by using them. Fire Protection systems do not reduce the need for a fire department response, they only enable us to better serve the public.

It takes just one step to gain momentum. That first step when coupled with the right attitude and the end game in mind, can lead to uncompromising results. That first step is difficult and more times than not, a solitary one.

We all go through personal struggle and times when the momentum decreases. What gives us the spirit to regain composure and the strength to pull through? Determination, Pride, Courage, Honor and Always Keeping the Faith.
