TIC Differences

If you wanted to look at planets in the night sky, would you use the binoculars you take on a hike for looking at wildlife? Probably not. You would use a telescope so you could see as much detail as possible. You would pick the right tool for the right job. 

This is a picture I took during training to show the difference between two thermal imaging cameras. Which one do you want in your hand when operating on the fire ground? I'd actually want both in with the crew but how and when each one is used will depend on the task. The camera on the left is a situational awareness TIC that can be used to locate fire or egress points. It has a lower resolution and a slower processor. I tend to think of them as a "personal" TIC because they are smaller and can be used in a pinch. The camera on the right is a decision making TIC that can be used to search and for tactical, strategic decision making. It has a higher resolution and a faster processor. I tend to think of these as an "officer" TIC because they provide more information in order to direct a crew's efforts. I’m not saying there’s anything wrong with the TIC on the left, but you have to utilize the correct camera for the task at hand. They are different tools for different jobs. 

Train with your TICs in different environments and, if possible, realistic temperature conditions. They will operate in different resolution modes and temperature scales depending on the temperature of the environment and it's important to understand how the TIC will react. Know what the icons on the screen are telling you. Understand the color palettes (ignore the spot temp) so you think of temperatures in terms of colors and react accordingly. Also work on your scanning speed and pattern to help prevent lag and optimize how you collect. Make sure you understand the limitations AND advantages of the TICs you use so you can do your job the best way possible. 

Be Smart - Stay Safe!

We Remember: Black Sunday FDNY

January 23rd, 2005.  One of the darkest days in FDNY history. A day the department lost multiple firefighters in two different incidents. Known to first responders worldwide as "Black Sunday."

Bronx: While performing a search during a three-alarm fire, Lieutenant John Bellew of Ladder 27, firefighter Joseph DiBernardo of Rescue 3, and  Lieutenant Curtis Meyran of Battalion 26 became trapped on the fourth floor of a four-story apartment. Due to the increased heat and fire, all three firefighters were forced to jump from the window to the ground. The apartment building was an older building from the late 1920s. The apartments involved were made into single-room occupancies (SRO). Each shares a common bathroom and kitchen. According to the NIOSH report, each SRO had a padlock on the bedroom doors. There was also limited access at the rear fire escape due to a partition with wood framing and sheetrock. In addition, there were no permits issued for construction in the building, and there were also no automatic sprinklers making the construction project a violation of local building codes. In addition to the three firefighters mentioned earlier, Brendan Cawley, Jeff Cool, and Gene Stolowski were severely injured in the jump. Later that day, Lieutenants John Bellew and Curtis Meyran succumbed to their injuries. Firefighter DiBernardo was promoted to Lieutenant in the spring of 2005. Unfortunately, Lt. DiBernardo passed away in 2011 due to complications with injuries sustained on January 23rd, 2005.

Brooklyn: Sometime just before 2 pm that same day, FDNY units were dispatched to a basement fire in a private dwelling. One of the first arriving units was Ladder Company 103. Part of the crew was firefighter Richard Sclafani who was assigned to search the basement. Due to fire conditions changing, firefighter Sclafani became separated from his company during the search. Minutes after being separated, Sclafani was located unconscious and in respiratory arrest. The NIOSH report stated firefighters worked on removing him from the building for 20 minutes. Firefighter Sclafani succumbed to his injuries, and the official cause of death was smoke inhalation and burns. January 23rd, 2005 marked the first time since 1918 that the FDNY lost firefighters in separate incidents.

Following the incident, the FDNY completed its internal investigation, and personal escape systems were purchased for all firefighters. Had the systems been available to the firefighters on Black Sunday, it would have saved the lives of Lieutenants Bellew, DiBernardo, and Meyran and prevented injuries to firefighters Cawley, Cool, and Stolowski. Black Sunday is a day that will be remembered forever in fire history. There is plenty of material on multiple sites providing information. I encourage new and veteran firefighters to remain educated on this day and learn from it.

In 2013, the Lt. Joseph P. DiBernardo Memorial Foundation, also known as the Joey D Foundation, was started to help train and equip firefighters in need. I have personally attended the yearly seminar they hold on Long Island. The training weekend is filled with two days of hands-on training followed by a day of great lectures. World-class instructors and firefighters teach all classes and lessons. The foundation raises money to provide fire departments with funding for personal escape systems, helping ensure an incident such as "Black Sunday" doesn't happen again.

Aerial Operations - The Aerial Truck Check, Part 1

Here is a look into how my Aerial truck check goes.

I usually start my Aerial truck check by walking around the Truck and checking for any obvious signs of an issue. Any issue, such as scratches dents, paint chips, doors missing, broken glass, you know the obvious things.

The next thing I do is go to the saw compartment. I take each of the gas- powered saws out of their compartment and start them. I allow them to idle outside is a position that they won’t wander off. If you don’t know what I mean here, just start a saw and place it on the ground in front of you. The saw will slowly wander off as it idles. So, place it in a crack in the ground or up against the wall of the firehouse. (NOTE: Make sure it doesn’t vibrate on anything that may become damaged, like paint on the firehouse wall.) I allow the saws to run the entire time I am checking the Truck. When Im done checking the truck, I fuel the saws, check bar and chain oil, and place them in service. The reason I do this with the saws is to allow them to run and get up to temp. It helps keep a healthy saw. Now there is a lot more to the saws here, but this is where I will stop for now.

Next thing I do is pull the truck out of the bay. I am going to check the engine fluids of the truck. Some trucks you have access points to allow you to do this. I prefer to raise the ladder and then raise the cab of the truck. This allows me to get eyes on the undercarriage. I check the fluids, oil, transmission, window washer, and the DEF. I will check Hydraulic oil and the generator fluids at this time as well.

Continuing under the cab, I check the belts, pulleys and anything bolted on the motor. Especially that alternator. I don’t know why but, these have a habit of losing bolts. In our Aerial class one of the things that we do is a truck check before operating the truck. We have found more than once, a loose or missing bolt and have had to send someone to get a bolt to continue the class.

Once the motor and it’s various parts are in working order I move on the exhaust, brakes, and springs. Making sure all are in tact with no “shiny” metal. This usually means there is something broken. Lets hope whatever is broken, let’s say a spring, that it is shiny and not all rusted, if it is rusty this means it has likely been broken for some time and maybe we missed it on our last truck check.


THE AERIAL TRUCK CHECK

While the cab is still up check the back side of the tires for any deformities low tread, bubbles, chunks missing. Remember these are Emergency Vehicles, not a fleet truck. If there are any issues at all document it and bring it to the attention of the proper person. For me it is an e mail to the maintenance supervisor and the OIC for the day.

As we continue under the cab we grab a creeper, if you have one, and begin to roll under the truck. Now with the Aerial up and the cab in the air it should be obvious to others there is a truck check going on, but to be safe place an Out of Service tag on the vehicle to your department SOG’s. This way you ensure that no one will run the truck while you are under it.

Continue to check for obvious issues, again broken springs and other hardware. Check the hydraulic lines, any coolant lines that may run here. Air brakes and the cans in the rear. It’s a good idea to drain the air tanks while you are here, this will remove the moisture from the air tanks and help prolong your airbrake system.

Look for anything leaking fluid. Investigate it. I know some trucks have their quirks but again these are Emergency Vehicles.

Check the inside tires for any issues, check air pressure on all tires, top off to your truck’s specifications.

Next month we will dive into the compartments of the truck and the aerial. Please remember this is just a way to do something and hopefully give you a few tips along the way. My approach is systematic and works for me. It may not all work for you. As always if you have something that may help, drop me an e mail and Ill put in here! Oh and BTW, the saws are still running, make them ready and put em back on the truck!

Peaked Roof Ventilation

The Cuts

There are many types of cuts, and we will discuss a few. But the main objective is to release the heat, smoke, and toxic gasses. To do this your hole size needs to be big enough to make a difference. Unfortunately, the day of the 4x4 hole is over. This size just doesn’t release the amount of heat needed to be effective. With all the synthetics and plastics in today’s homes, and the rate of heat release these products produce, it just makes sense to make the hole larger. You may not find this in many books, but from my experience and the experience of other like-minded Firefighters I network with; we agree that at least a 4’x6’ hole is the new minimum.

There are many ways to accomplish this size and larger hole. I am a big fan of two cuts. The Louver cut and The Milwaukee cut. Each has their place. Now there are many more to consider but these are the two I am going to talk about.

THE LOUVER CUT

A two panel louvered cut on a residential roof will provide an opening that is about 4x8 foot. Starting at a high point, near the ridge and working your way across the top. Start your cut by plunging your saw into the roof, slide the saw to the left until the resistance is greater. This means you have hit the roof rafter. Now slide the saw in the same kerf cut to the right until that heavy resistance is meet again, now roll the rafter. To roll the rafter, you lift the saw out of the roof material and cut just the sheeting not the rafter. Then as you have gone over the rafter plunge the saw again until the next rafter. Continue this for process. Cut, roll the rafter, cut, roll the rafter, and cut to the rafter. This will give you about six feet in length. Now cut downward toward the soffit, about four feet. If you’re unsure how far four feet is, count rows of shingles. Each row is about six inches. That’s a foot for every two rows. Cut down eight rows. Now work your way back. Same cut and roll method. This time after you roll the rafter, stop. Reach up to the top cut, make a cut from your top cut to the bottom cut. This should be half way between the rafters. Continue working your way back to your roof ladder. Make the last vertical cut and now wait for the word to open up. Punch through with your six-foot hook, the roof material will “louver” on the rafter.

After the cut is made do not forget to punch through the ceiling material to allow for proper ventilation. As soon as the cut has been made, firefighters should evacuate the roof as quickly and as safely as possible.

THE MILWAUKEE CUT

The Milwaukee cut is a great cut that catches all aspects of your roof. It runs from the peak to the soffits. It is usually around four feet wide. To start the cut is just like the start of your louver cut. The only thing I would add is an inspection cut at the top left and right. This becomes important when you are ready to pull the material from the cut. As this allows you to get the hook into the material and pull. I should add that it can be done with a rotary saw as well as a chain saw.

This cut is labor intensive. It can be done with two Firefighters but 3 is optimal. You will need two roof ladders, one on each side of your cut. How you accomplish this cut is up to you. Meaning that you can run two saws or one. But I like the old adage that two is better than one.

Either way, after making your cut across the top and then making your inspection hole, continue the vertical cut all the way to the soffit on both sides.

Climb back to the peak and begin pulling the material from the cut. Again punch through the ceiling material.

The advantage to this cut is in a lot of New England homes there are many voids in the roof area. Especially in Cape Cod style homes. With the attic space above and the knee walls all open this allows you to properly vent the whole structure

SAFETY CONSIDERATIONS

Pitched roof ventilation can be one of the most hazards operations on the fireground, yet it is one of the most important assignments.

There are numerous things to consider when working on a roof. Number 1 the fire is under you! Sounding the roof is a must, know and understand the sound of a solid and a spongy roof. Know that in older homes the ridge and valleys are usually the strongest, but still sounding is a must.

Use a roof ladder whenever you can. Yes you can walk a pitch of 6/12 or less but err on the side of caution. If you cannot see, meaning heavy smoke conditions, then get on your knees. When you have an SCBA on you have balance issues, add a pitched roof and low to no visibility, this could be a bad combination. Always try to work your way back to your roof ladder. This may not be able to be done 100% of the time but do it as much as you can. Know the signs of a bad roof. Bubbling shingles, smoke slithering from under shingles or through metal roofing. Any sags in the roof or in between the rafters. Understand building construction, especially roof construction. Understand what types of roofing material is on the roof, how many layers of shingles and sheeting material. If you are unaware of the construction type, then cut inspection holes. This may save you some time and may even save your life.

Mother nature is always messing with us. From snow to sleet to freezing rain. Be aware of these conditions and take appropriate actions. Use of a roof ladder even on a low pitch is a good start. Some type of striking tool, should already be in your tool selection, to break away the ice, maybe add a shovel as well.

Get out in your community and see what’s out there! Because you don’t know what you don’t know!

Remembering Firefighter John Nance

10:10 pm, the Columbus Division of Fire was dispatched to North High Street for a report of

smoke coming from the 1st floor of the Mithoff Building. At 10:12 pm, Engine 1 arrived on the scene

immediately, followed by Engine 9 and Engine 3. Firefighter John Nance was acting Lieutenant on Engine

3.

The Division of Fire used a “battle plan” consisting of two task forces to fight downtown fires.

Acting Lieutenant Nance was with Taskforce two and was staged at the rear of the building. His crew

noticed smoke hanging low to the sidewalk, indicating a basement fire. Nance and his crew from Engine

3 entered the building, joined by teams from Ladder 2 and Engine 2 shortly after. The smoke was so

dense the crews were forced to crawl while advancing the charged hose line.

Approximately 30 minutes into the incident, a second alarm was transmitted. While there was

still no visible fire, the smoke was increasing. Met with a significant amount of smoke and heat, Nance

and his crew continued to search for access to the basement. Unable to access the basement and

quickly exhausted, Nance and his crew vacated the building to cool down and switch out air bottles.

Now, after numerous research attempts, it seems no one knows what happened to Firefighter

John Nance other than he fell through the floor into the basement. A hole was found where he fell

through, leaving firefighters and officials to believe he was cutting a hole to the basement. Firefighters

were attempting to rescue FF Nance utilizing ropes and hose lines. As the fire began to show, Nance had

run out of air. The Assistant Chief started to remove people from the fire. Using a “search rope” type

technique, firefighters once again entered the building in a final attempt to save FF Nance. Firefighters

were again pulled from the building; last attempts were made to gain access to firefighter Nance, but all

turned empty.

Eventually reaching the 4th alarm, the fire was placed under control around 5 am.

Unfortunately, FF Nance did not make it out of the fire, and his body was recovered on the afternoon of

July 26th. According to reports, the building was intentionally set on fire, making this line of duty death a

murder.

As always, a line of duty death results in training tactics for firefighters. This LODD brought us

the “John Nance Drill” or “Hole in the floor.” The drill removes firefighters from a basement should stairs

or easier access not be available. I have attached a link to watch it here

https://www.youtube.com/watch?v=umzJmtMHrdA this incident also shows the importance of using a

search rope or tag line. Although firefighters had a hose line to follow in this incident, a search rope still

provides an additional tool to help guide a firefighter out and to assist firefighters in to assist a downed

firefighter should anything happen.

I must admit, when looking for my LODD topic this month, I was unaware of John Nance. As I

researched it and found multiple articles and stories, I became a bit obsessed with always looking for

more information. To my knowledge and what I have seen, the murder has yet to be solved, officials and

investigators have found why the building was set on fire but have yet to find out who started it. I found

a story written by Michael Norman on FFprovinggrounds.com. Mr. Norman, a writer for Columbus

Monthly, provides detail on the incident in his write-up. I encourage anyone unfamiliar with this to do

an internet search and read up on it.

Food Trucks and Firefighting Concerns

For decades food trucks and food carts have been service food to people on street corners, carnivals and events all around the world. In today's world, food trucks and food carts are popping up everywhere. From birthday parties to school and work functions you name it and a food truck is probably there serving food. These carts or trucks are known as Mobile Food Preparation Vehicles or MFPV for short. Some are trucks designed to house a kitchen setup and others are trailers pulled by a truck or SUV. Either way both serve the same purpose, preparing food for customers.

 

These trucks provide a unique set of challenges for firefighters and provide a few hazards that commonly scene when fighting vehicle fires.

 

We are very well aware that cooking is the leading cause of accidental fires in the United States with respect to residential fires. With respect to commercial occupancies, these structures are more well equipped to handle the potential of an accidental mishap in the kitchen. Commercial kitchens mitigate the risk through hood suppression systems over their cooking appliances such as ovens, burners and grills. The same goes for MFPVs…but not exactly.

 

The newly designed, custom-built food trucks will be equipped with hood suppressions systems however the older retro-converted trucks may not be as equipped. Making the workers not as fortunate should an accidental kitchen fire breakout. In all cases, all MFPVs will be equipped with portable fire extinguishers to suppress kitchen fires from grease, fat and cooking oils.

 Propane Tanks

The most significant risk of fires to MFPVs are propane tanks. According to the NFPA, 68% of food truck fires are related to leaks or failures in the propane tanks themselves. Propane is used in various ways with respect to food trucks. For one, they're used as fuel for cooking and possibly refrigeration.

 

While propane is generally safe to cook with, a small 20-pound cylinder on a backyard grill has the explosive equivalent to 170 sticks of dynamite. MFPVs can carry around 100-pounds of propane cylinders at a time in order to be efficient and produce food services to customers. One hundred pounds of propane is capable of producing more than 2.6 million BTUs (British Thermal Units). One food truck carrying that amount of propane can generate 6 times more energy from an exploding propane tank than a backyard grill using a 20-pound propane tank.

 

Since these trucks are constantly moving from place to place, the risk of a propane failure can increase. This is due to the trucks driving on bumpy terrain or hitting potholes. Both of which can loosen the connections and fittings or cause structural damage to the tank. With respect to air, propane is heavier. In fact, propane is 1.55 times heavier than air which causes it to sink. Thus, causing a pooling effect near the floor should a tank leak. Because of this, a single spark from the cooking appliances has the potential to ignite the gas.

 

Many trucks carry spare tanks or have their current tank fitted to the outside of their MFPV which decreases the risk of leaks inside the unit. The risk this does carry is tank explosions from minor collisions on the roadway or single vehicle accidents.

 Generators

Older MFPVs are more likely to pose a risk with the use of portable generators. These are used to run electricity to the truck. Older MFPV's or converted ones could possibly lack the proper ventilation of the off gases from the generators which raise the risk of carbon monoxide emergencies in the mobile unit. 

 Past Incident

On July 1, 2014, in the Feltonville neighborhood of Philadelphia, a leaking propane tank ignited and exploded. The truck operator and her daughter were severely burned and died three weeks later. An additional 10 others were injured as a result of the blast.

 

Since then, the NFPA has made changes to NFPA 1 and NFPA 96. The leaders at the NFPA concluded that an easily adopted national standard would go a long way in increasing the number of communities with comprehensive food truck safety regulations.

 

These standards and changes can be found at the links below:

Remembering the Hackensack Ford Fire

On July 1, 1988, when firefighters of the Hackensack Fire Department arrived on scene of the Ford dealership on River Street in Hackensack, NJ around 3pm, they did not know how deceptive the fire would prove to be. They did not know that five of their fellow firefighters would not be coming home. On the initial alarm, Hackensack firefighters on two engines, one ladder and chief car responded to a reported fire at the Hackensack Ford auto dealership. During fire operations, fire was discovered to be burning above in the truss over the service area and was vented by the truck company on scene. Fire suppression was attempted by both engine companies through two ceiling hatches above the service area. Shortly thereafter, an evacuation order was transmitted over the radio of which were not acknowledged by any of the units working on scene.

Otherwise known as the Hackensack Ford Fire, this fire claimed the lives of five firefighters battling a fire in a bowstring-truss building when the roof suddenly collapsed. Three of the five firefighters lost their lives in the middle of the service area of the dealership. The other two firefighters became trapped in the rear storage room and were unable to be rescued. After approximately 1 hour into the operation, these five firefighter lost their lives and were the first line of duty deaths in the department's 117 year history to that point.

Remember & Honor

Capt. Richard L. Williams (Engine Co. No. 304)

Lt. Richard R. Reinhagen (Engine Co. No. 302)

Firefighter William Krejsa (Engine Co. No. 301)

Firefighter Leonard Radumski (Engine Co. No. 302)

Firefighter Stephen Ennis (Engine Co. No. 308).

34 years later this fire has had significant impact on today's fire service. This fire is one of the most analyzed LODD events in the history of the fire service. Numerous issues were noted from the incident including a breakdown in communications. The findings and observations of this fire are still valid today.

The lessons of this fire has resonated deeply within the fire service across the country. The Hackensack Ford Fire caused the fire service to begin looking at building construction on a more serious level especially when operation in and around truss construction and having the ability to identify construction types and truss. It also highlighted a weak command structure, insufficient and ineffective radio communications along with a lack of portable radios for firefighters and a lack of manpower. These lesson stay true to this day.

In an article published the day after the tragedy, Fire Chief Anthony Aiellos said, “There are only 100 of us in this department, and this is just a small place. In a town like this, these are your friends. These were good men.”
