Leather Chainsaw Bar Guard Helps Crews Operate Safely

By Raul A. Angulo

Appearances are important. Our conduct sends a message. A sloppy uniform sends a message. A dirty fire apparatus with body damage sends a message. How we carry our tools sends a message. What message do we want to convey when we show up at a structure fire? Hopefully it is one that demonstrates our mission of saving lives and property.

Look at the condition of some of the scabbards that sheathe one of our primary tools-the chainsaw. Many fire departments cut up sections of old 2½-inch hose for chainsaw scabbards. That is a great way to recycle and get the most out of an old piece of fire hose, but we often forget to change it out. The hose absorbs the oil and dirt and, after awhile, the saw looks like it belongs in Jed Clampett's tool shed. If you're going to use fire hose, change it out so it at least looks clean.

scabbards. They get extremely dirty and look very
unprofessional. This saw was probably taken off the back of Jed
Clampett's truck-otherwise known as Ladder 10. (Photos by

But in our line of work, the real statement of class and professionalism lies in leather. The iconic symbol of our industry that is internationally recognized is the fire helmet. And, the most expensive helmets on the market are the Cairns natural leather "New Yorker" and "Sam Houston" models. They range between $500 and $600 apiece. Some say there isn't a nicer, classier helmet on the market. A firefighter who wears one of these helmets is definitely making a statement. If you look at the finer things in life-car interiors, furniture, brief cases, purses, wallets, shoes, or jackets-they're all made of fine leather.

Paul Davenport is the inventor of the SawGuard™ and owner of SawGuard, LLC, based in Yakima, Washington. The SawGuard is a custom leather bar cover for chainsaws. This scabbard is based on a design he created back in 1978 when he acquired his very first chainsaw, a Homelite Super XL with a 20-inch bar. He was always worried about the blades being uncovered. The exposed bar was something that could damage or become damaged. It could also cut, scratch, or become dull because of hard surface contact. What we typically refer to as the teeth of a chain are actually individual knife blades.

SawGuard covers

SawGuard covers are made from time-tested harness leather, a
thick oily leather that has great strength and durability and resists
tearing and cuts. The cover soaks up excess oil from the bar,
which hydrates the leather and keeps it pliable and water-
resistant.

 

The exposed bar was also a safety concern for him because he had young children. So, he asked his grandmother, who worked with leather, if she could make a scabbard to cover the bar. It had to be something that would not be cut or damaged by the blade itself, and the sewing, which would hold the case together, would have to be protected from the saw's sharp cutting blades. She told him she would play around with his design. Several months later, she presented him with the first prototype. It was two pieces of heavy duty harness leather laminated together with leather spacers and held together with stitching and rivets.

Redundancy in Water Delivery

Richard Marinucci

As I write this, many parts of the country are finishing one of the most severe winter weather seasons in many years. There has been extreme cold and a lot of snow.

This has created operational challenges for many fire departments. In some cases, fire hydrants have been covered with snow and the cold weather has made other hydrants inoperable because of freezing. Of course, some folks think there is a simple solution-just dig out all the hydrants and test the hydrants regularly. If it was only that simple!

The point of this article is not to discuss the specific challenges of weather extremes but the need for redundancy in water delivery should the first option fail. As an example, a few years ago an entire water system went down during the summer months because of a power failure. Obviously, many departments were scrambling to come up with an alternate water source.

Have a Backup

Departments should have choices if the first option doesn't work, regardless of why there is a failure. In areas served by fire hydrants, this could be as simple as knowing all the options available for hydrant selection. There should be a procedure that calls for responding units to take alternate routes to approach the scene from different directions. This would generally allow for multiple choices and a backup plan should the first hydrant fail for some reason. This seems so simple and logical that you might wonder why you would even need to tell anyone that this should be a standard operation. But there are some considerations, including organizational discipline, for responding appropriately on each call. Occasionally departments become complacent and don't always remember their basics, especially if a department, a specific station, or even a shift doesn't respond to many structure fires.

There is more to preparation than just driving a different route to the scene. Those who arrive first must leave space if they need subsequent responding units' water supplies. The first-arriving crews also need to be efficient and able to determine early whether or not their first water supply option will work. Departments that are prepared for the second or even third option can transition smoothly. And, very often the public will not even know there was a problem. On the flip side, if you put all your eggs in one basket, everyone will know there was a problem. Not only will this negatively impact your suppression efforts, it could create a political issue long after the fire has been extinguished.

The most important reason for a smooth transition is relative to firefighter safety. Many departments initiate operations with tank water and rely on establishing a water supply from the fire hydrant quickly so that it is seamless for the operation. Firefighters initiate interior attacks, and as long as the continuous water supply is established before the tank water is depleted, there is no issue. However if there is any significant delay, it could place interior units in peril and expose them to additional risk.

Staffing Impact

Redundancy is easier with adequate staffing by dispatching enough units on the first alarm. This can be challenging for many departments that have seen reductions in these areas in the past few years. In this time, the perceived success of many departments may have led to complacency or overconfidence. They have not had any fire hydrant issues or difficulties supplying water. They, and too often those that fund the department, look at this as an opportunity to reduce costs through less staffing and apparatus. Like so much of what occurs in the emergency business, it isn't a problem until something unusual occurs. Then someone is asked to explain.

There are other options to help with creating backup plans. Some areas have access to tanker trucks or water tenders-different terms for the same thing, depending

Forward-Looking Radar, 360-Degree Cameras Help Prevent Collisions

By Alan M. Petrillo

The safety of firefighters inside fire apparatus when traveling to and from an incident is of paramount importance to all fire apparatus manufacturers, no matter what type of vehicle they are constructing.

Strong structural members, air bags, electronic stability control, occupant detection systems, and other components address the safety aspects of a fire vehicle, but other technologies are also taking hold.

One apparatus maker, E-ONE, has developed a protection system that incorporates an additional two technologies new to fire service apparatus-a forward-looking radar that can detect developing rear-end collisions and a 360-degree bird's-eye view camera system that gives an operator situational awareness of his vehicle on the road.

ProTech

Joe Hedges, E-ONE's product manager for aerials and chassis, says that his company's ProTech system is a comprehensive safety package for all E-ONE chassis. "It starts with the roll cage cab we build that can withstand two times the National Fire Protection Association (NFPA) and Society of Automotive Engineers (SAE) impact requirements and five times the roof load requirements," Hedges says.

ProTech also includes front and side air bag systems with integrated seat belt pretensioners; electronic stability control that constantly monitors driving conditions; an occupant detection system that gives audible and visual warnings; backup sensors that warn a driver of potential obstacles at the rear of his vehicle; a 360-degree camera system; and OnGuard, the forward-looking radar system.

OnGuard

"We worked with our brake system supplier, Meritor Wabco, to integrate OnGuard into our chassis," Hedges says. "The system has dual zones-one that takes a wide and close look in front of the vehicle and the other up to 600 feet ahead to detect any kind of developing rear-end collision. OnGuard looks at thousands of items ahead of it but tracks in great detail six vehicles as to their speed relative to your speed."

Hedges says that OnGuard bases its calculations on the driver's steering position, the vehicle speed, whether or not brakes are being applied, and what the objects in front of the vehicle are doing. "If OnGuard detects a potential impact, it watches if its driver is doing something about it-for example, steering to avoid. If he is and that path is not clear, OnGuard will intervene. It's constantly watching all elements."
