Using a dozer to mop up a structure fire

Dozers are commonly used on vegetation fires, but it is unusual to see them at a structure fire. In the video above, Los Angeles County Fire Department used a dozer to assist firefighters during the overhaul or mop up stage of a structure fire in Lancaster, California Thursday night. Apparently there was a large quantity of material inside the commercial building that would have been difficult to completely extinguish without spreading out the burning debris. It looks like they were using foam or a wetting agent in the water to achieve greater penetration.

Radio headsets for dozer operators

Should all heavy equipment operators have access to radio headsets?Tim Banaszak pointed out to us that while working on a fire, communication between an operator and the Heavy Equipment Boss (HEQB) can be difficult or impossible. The equipment makes so much noise that it can be a challenge to hear the radio. Even relying on hand signals is not reliable due to dust and vegetation, Mr. Banaszak said.

We are still throwing rocks or sticks to get the operator’s attention, YIKES! The high RPM noise makes a portable [radio] useless. All other fireline operations have a clear and reliable communication link. Just hearing the word STOP can prevent equipment damage, an injury, or even worse.

He suggests that a cache of headsets for radios be available that could be checked out at a fire with the operator’s portable radio.

What do you think? Is this a problem that needs solving?

The Air Force has one firefighting dozer team

The only firefighting dozer team in the U.S. Air Force is at Vandenberg Air Force Base in southern California. The 30th Civil Engineer Squadron heavy equipment operators’ fire dozer team consists of approximately ten Airmen and civilian workers. Their job is to support the firefighters by helping to limit damage and contain the spread of wildfires.

“Because of the sheer size of our equipment we can accomplish a lot within seconds,” said Staff Sgt. Mark Robertson,  a heavy equipment operator. “When we go out to a fire, those who have already responded breathe a sigh of relief because we can accomplish a huge amount of work in a short amount of time.”

When a fire breaks out, the base firefighters are the first to respond. When the fire is too difficult to control, the fire dozer team is called to assist.

“We are supporting the fire department, and will get their call if they need us,” said Raymond Boothe, 30th CES equipment supervisor. “We are not sitting around waiting for a call though — we are constantly working all over base, performing our job as heavy equipment operators.”

“Vandenberg is the only base in the Air Force that has a fire dozer team,” said Robertson. “So this is the only place in our career that we are going to get this kind of experience and training.”

Airmen also receive a Red Card certification, which states the holder has the experience and training necessary to fight wildfires. This certification is utilized by both state and federal fire agencies and is useful for civilian jobs across the nation.

Another significant component of the job is supporting the space mission. The fire dozer team is on stand-by during every launch, prepared to contain fires that start and prevent damage to base assets.

Adventure Fire burns 100 acres northwest of Placerville, California

The Adventure Fire burned about 100 acres 8 miles northwest of Placerville, California Thursday afternoon. The only reason we’re writing about this 100-acre fire is that we ran across this excellent photo of a dozer that we wanted to share.

But, since we’re here — we might as well mention also that we have an unconfirmed report saying the first engine that arrived at the fire observed a slow rate of spread and canceled the aircraft. Sometime after that, the slow rate of spread changed to a rapid rate of spread.

CAL FIRE said it was reported at 12:05 p.m. In mid-afternoon quite a few additional resources were ordered, including several crews and an “immediate need” strike team of engines. Later, many resources, both on the ground and in the air, were able to corral it. By about 5 p.m. most of the spread had been stopped.

Below are the weather observations taken from the Pilot Hill RAWS weather station 3 miles west of the fire:

Weather at Pilot Hill RAWS station, July 16, 2015.

By 1 p.m. it was 90 degrees with 26 percent relative humidity and a 7 mph wind gusting to 13. Over the next three hours it got hotter and drier.

One of the cardinal rules of initial attack on a wildland fire is, do not turn around any responding firefighting resources until you are absolutely, totally, unreservedly, unconditionally, altogether, certain that they are not needed.

Have I ever mentioned Dr. Gabbert’s Prescription for how to keep new fires from becoming megafires?

Rapid initial attack with overwhelming force using both ground and air resources, arriving within the first 10 to 30 minutes when possible.

Followup on dozer rollover in California

The California Department of Forestry and Fire Protection has released a preliminary report on the July 6 dozer rollover on the Monticello Fire southeast of Lake Berryessa in Yolo County.

The summary:


“On July 6, 2014, at approximately 1320 hours, a CAL FIRE dozer was operating on Division M of the Monticello Incident. The dozer was working sidehill, constructing fire line in steep terrain. The dozer became unstable and rolled at least two times coming to rest on its tracks in a small drainage below. The operator sustained a head injury and a possible loss of consciousness.

Fire line personnel immediately responded to assist and treat the operator. A CAL FIRE helicopter performed a hoist rescue. The operator was transferred to a waiting medevac helicopter and was transported to a trauma center for evaluation. The operator was released from the hospital later that evening.”
