Dressed for Success: A Firefighter's Turnout Gear - Information for Writers with Patti Phillips




What does a firefighter wear? Today, we have guest blogger Patti Philips. Patti and I met at Writers' Police Academy, and she is a kindred spirit when it comes to research. She also happens to be a professional photographer, so ThrillWriting loves the visuals that Patti brings to the blog posts that she's done for us. It's true, a picture can help us write a thousand words.

Patti - 

Firefighters have one of the most dangerous jobs in the world.



Walking into a house fire that could reach 1000 degrees in under a minute (that’s not a typo) or a chemical fire that may reach double or triple that temperature in seconds, while battling smoke inhalation as well, means a firefighter’s life depends on being supplied with the best equipment that money can buy. Without the proper gear, firefighters can’t stay inside a burning structure long enough to rescue victims or fight the fire successfully.

So, what is the right gear that keeps them safe and still allows them to do their jobs?

Tim Fitts, a veteran firefighter in North Carolina, and Coordinator of certification classes for firefighters and rescue squads at Guilford Technical Community College, demonstrated his gear on a 95 degree day in September. Fire isn’t selective about the weather, so it’s a good thing for us that firefighters train and work under all kinds of conditions.




The firefighter uniform is generally called ‘turnout gear’ by firefighters because they turn it inside out when not in use, so that they can step into it quickly and pull it on/up when the fire bell/siren sounds. Firefighters need to get completely dressed in about a minute, so any safe system that will speed up the process is used. Some guys pull on the boots and pants, grab the rest of the gear and finish getting dressed in the truck as it pulls out of the fire station.



The official name for the gear is Personal Protective Equipment (PPE).

Parts of the firefighter uniform:

While on the job at a fire or rescue operation that might result in a fire, most firefighters will wear these pieces of clothing:

  • Boots, insulated with steel toes and steel shank
  • Cotton t-shirt
  • Gloves, insulated leather
  • Helmet, with neck flap and eye protection
  • Hood, Nomex
  • Jacket, insulated, with Velcro and spring hooks
  • Pants, insulated, with Velcro and spring hooks, with extra padding and pockets
  • Suspenders



These three hoods are each made of different fabrics:

  • Kevlar blend
  • PBI/Kevlar
  • Nomex 
Firefighters put a hood on before the jacket, so that it sits properly on the shoulders. They tend to wear two hoods to protect against a flashover, giving their heads the extra defense needed in the intense heat. If a flashover occurs, the firefighter will have about two seconds to get out of the building. If the hoods are not providing enough coverage, it will feel like 1000 bees stinging the ears at one time – it’s too hot to stand. It’s time to get out.




The helmets are made of thick, heat resistant plastic and often include Kevlar or Nomex flaps for the ears.

Firefighters are taught to fight fires on their knees (not while crawling) so the extra padding helps cushion the wear and tear on the knees.



In addition, the firefighters put on:
  • Airline and pressure gauge
  • Flashlight
  • Positive pressure mask
  • PASS device
  • Radio
  • SCBA shoulder straps, airtank bottle and backpack frame

The PASS device (Personal Alert Safety System) is a personal safety device used by firefighters entering a hazardous environment - a burning building. When the firefighter does not move for 30 seconds, it makes a loud, shrill, really annoying sound, letting others in the area know that something is wrong.



The mask on the left is a newer model, the one on the right? Older. There has been an upgrade in technology for the plastic in the mask, developed because at high temperatures, the old plastic would fail (melt). It was the weakest part of the uniform. The new version will not fail as quickly.









Note that even the air tank is protected with a fire retardant fabric.


The idea is to be protected from the fire and to be able to breathe safely while he/she works. The positive pressure mask on the SCBA (Self Contained Breathing Apparatus) gear keeps the toxic air out as much as possible by allowing the tank air to flow continuously, even if the firefighter is not inhaling. By the way, the tanks are full of compressed air, not oxygen.







Most of the clothes have reflective tape so that the firefighter can be seen more easily through the smoke and low light/darkness. Some departments are large enough that they use color-coded reflective tape in order to tell the full-time firefighters and the volunteers apart.




The uniforms are sized to the individual firefighters, so that when they bend over, there is at least a two-inch overlap with the fabric pieces, and no skin is exposed to the crippling, blistering heat.
Indicating the length of the jacket.


Hip boots of years ago, are now old school because of the area of the body they left unprotected from heat. Now the boots have steel toes and shanks and are calf high or knee high in length.

When fully dressed, the firefighter is wearing about 70 pounds of equipment. Add more weight for the tools they have to carry – picks, axes, etc – needed to fight the fire.

After ten years, all turnout gear must be thrown away. It wears out because of repeated exposure to the intense heat and toxic elements. Many large, active fire departments dispose of the clothing after only five years, because of their more frequent use and improvements in technology.

Firefighting gear is not fireproof. It is fire retardant.

Some of the clothing has 3 layers, each layer performing a different function. People can only tolerate temperatures to 135 degrees, so the specialized fabrics extend the time available to do the job. Firefighters get very uncomfortable at 250 degrees, and the time limit for the firefighter at that point is about 30 seconds to reach someone and get out. One of the firefighters at Command keeps track of the men/women - where they are in the structure and how long they’ve been working the fire.

Nomex degrades at 400 degrees, so needs to be used in addition to other fabrics if fighting a structural fire. It tends to split when the wearer is running. When combined with Kevlar, it becomes more flexible and the fabric breathes a bit better.

PBI degrades at 1100 degrees, allowing a much better chance for the firefighter to stay safe while fighting a house blaze. It stays intact in the extreme temperatures and allows the firefighter extra time to get to a victim and then get out.

Gortex helps shed water


Heat goes through each layer a bit at a time. Each layer is a necessary barrier, in its place to protect the firefighter and keep his body from getting hotter than is safe.

After fires, all of the clothing needs to be taken apart and washed, because everything in a fire is carcinogenic. Hmm…that means that the entire time a firefighter is working the fire, his equipment has to protect him from the flames and the smoke, as well as anything else thrown into the air, both in the active fire and in the area outside the building.

Some fire Captains insist that the clothing be stored away from the sleeping area at the station, because it may still contain toxins even after being washed. If you get a chance to visit a Fire Station, you might be able to tell where the gear is kept, before you ever reach the room. The smoky odor is sharp and unforgettable.

                                         Cost of Basic Turnout Gear (approximate)
      • Pants, jacket, gloves - $1,150.
  • Boots - $175
  • Helmet - $150
  • Nomex hood - $60.
  • PASS device - $300.
  • Airpack with mask - $4,500.



















Tim Fitts told us about the testing going on at NC State’s College of Textiles, in the search for better, more effective, fire retardant fabrics.

Every second counts when rescuing you or your pets in a fire. We know that a simple house fire can fully engulf an 8’x10’ room in 90 seconds. That’s not a typo. If the firefighters are on the scene before that happens to the entire house, they need as much lead time as possible in order to keep a rescue operation from becoming a recovery operation. That’s when the best turnout gear on the market is worth every dime.

The SIRCHIE Education Training Facility Tour - by Patti Phillips




SIRCHIE makes hundreds of products for the law enforcement community and offers classes in how to use those products at their Youngsville, North Carolina Education and Training site. Several crime writers were allowed an unprecedented opportunity to attend a five-day, hands-on training session, so that we could learn more about the latest and best gadgets being used to catch the crooks.

During the first two days of Evidence Collection Training, we used a number of chemicals, fingerprint powders, and brushes, and employed several different fingerprint lifting techniques on a variety of tricky surfaces. We discussed the benefits of both cheap and costly Alternate Light Sources.

Our notebooks were filling up and theories of the perfect crime were flying around the class. We kept quizzing Robert Skiff, our instructor, (SIRCHIE Training Manager/Technical Training Specialist) about ways to ‘get away with the murder of the decade.’ But as we learned, there is no perfect crime. That pesky trace evidence will always be waiting at every scene for the investigator to discover it, photograph it, tag it, bag it, and transport it without losing the integrity of the sample.

It was time to visit the plant – see how the powders, brushes, and other crime scene paraphernalia were made.

SIRCHIE manufactures most of its products in-house. The specialized vehicles for SWAT, bomb rescue, arson investigation, and surveillance work, etc., are built in New Jersey, but the smaller products are produced right in North Carolina.

Security was carefully controlled throughout our tour. Most of our group writes crime fiction, so we are always looking for a way our fictional criminals can break in (or out of) a wild assortment of locations. As we walked through the stacks and aisles of products, we commented to each other on the smooth organization and many checks SIRCHIE had in place. Cameras everywhere. Limited access to the assembly floor. Labyrinths a person could easily get turned around in. If we got separated from the group while taking an extra photo or two, we were found and escorted back by an always friendly employee.

Of course, we couldn’t turn into rogue students anyway. Our fingerprints littered the classroom and they knew where we lived.

Security plays a part in the assembly model as well. Each product they create is put together from start to finish by hand. There are no assembly lines because of trade secrets and a dedication to preserving product integrity. Personnel are carefully screened before being hired and qualification for employment includes graduate degrees. No criminal history whatsoever is allowed. Every employee comes through the Evidence Collection Training Class so that they understand what SIRCHIE does as a whole.


Tool and Die Machinery

Templates for the various products are created in-house. The operators of these machines are highly trained experts. Quality control is paramount, so training is constant.


Printed Supplies
Scale Strips
All the printing is done in-house. The printing area was stacked with cases of items being printed for shipment. We saw ink strips large enough to process tire treads.

Field Kit
Field Kits are created for general use by investigators, but can be specifically designed for a special need. The small vials contain enough chemicals to test unknown stains and substances at the scene. Note the dense foam holding the vials and bottles firmly in place. The kits are usually kept in the trunk and probably get tossed around quite a bit. The foam insures against breakage during car chases and while bumping across uneven road surfaces.

Finger Print Brushes
There are fiberglass brushes, feather dusters for the very light powder, regular stiffer brushes, and magnetic powder brush applicators.



Brushes Completed
We were lucky enough to see fiberglass brushes being made.



Gun Box
If a handgun is seized for evidence, there needs to be a simple, yet effective way to track chain of possession.
*Bag the gun to preserve the fingerprints and
*drop the gun in the box.
*Then fill in the blanks on the box.
*Easy to stack and store until needed.
Think of all the cases that may be ongoing in a large jurisdiction – the evidence is not sitting at the police station. It’s in a warehouse someplace, and needs to be easily identified when required for court. In addition to several sized boxes for guns and knives, etc. SIRCHIE also provides an incredible assortment of resealable plastic bags for preserving evidence like clothing, unidentified fibers, etc.


Wendy with Magnetic Powder
Magnetic powder was being processed that day and then put into rows and rows of jars and jugs. Before it is sent out to the customers, each lot is tested for moisture content, appropriate ratio of ingredients and other trade secret tests. We joked about taking some back to class for the next round of fingerprint study and were surprised by how heavy the jugs were.


Cyanowand Cartidges for Glue Gun
No, she’s not making bullets. She is assembling the cyanowand cartridges used for fuming with superglue.

SIRCHIE Makes Riot Gear
Riot Helmet Drills
This is not a photo of something from a SyFy movie. At the center of the shot is a helmet template. The drills encircling the template are aimed at spots where holes are needed for each helmet, depending on the type of helmet in production. All the holes are drilled at the same time.

The Optical Comparator, as well as the other machines, are built to order by hand.


While in the warehouse, we learned that if a product is discontinued, it is still supported by SIRCHIE. That means that if a law enforcement officer calls up with a problem a few years after purchasing a machine, he can still get help. Reassuring for jurisdictions with a tight budget that can’t afford to replace expensive equipment every year or two.

SIRCHIE sends supplies to TV shows, so next time you’re watching a fave detective or examiner lift prints with a hinge lifter, it may have come from SIRCHIE.


Great tour, great people who work so hard to keep the law enforcement community supplied with the gear needed to catch the bad guys.
