Last month, I discussed the advantages of using a thermal imaging camera (TIC) to fight aircraft fires and took you through the events of a controlled burn aboard an aircraft fire simulator. In this column, I’ll focus on the benefits of using a TIC to fight shipboard fires. The majority of firefighters are trained to battle structural fires, but a number of fire departments fight fires aboard ships. Using a TIC can be an effective tool for firefighters who face the challenges of a shipboard fire.

Shipboard Fires

Think of the obstacles facing a firefighter onboard a ship when a fire breaks out. The narrow passages, bulkhead doors, numerous deck levels, steep stairwells, heavy fuel loads, and maze-like features of a vessel can be disorienting and dangerous for firefighters. Although the threats of a ship fire may be different from those of an aircraft fire, many of the TIC challenges are similar.

First, large vessels are constructed primarily of steel. Steel, like aluminum, will not show a firefighter using a TIC its true temperature. For instance, a bulkhead door hiding a fire may not display as white on the TIC during the initial growth of the fire. However, once the steel heats up enough, the TIC will help firefighters identify the location and extent of a fire as well as the potential for spread.

Second, the risk of firefighter disorientation on a vessel is high. The structure is maze-like, and firefighters must be extremely cautious about remaining oriented with and without the TIC. Firefighters cannot rely solely on the TIC to lead them into and out of the environment. While this is true in a structure as well, the very nature of the vessel’s decks and passages makes orientation a life-critical issue on a ship.

Although there are many obstacles that firefighters face on a vessel, the use of a TIC can improve the effectiveness of bringing a fire under control while keeping firefighters safe. Since obstacles and passageways are easily identified on a vessel, a properly trained team will advance more quickly to the area of the fire when using a TIC. This means that the firefighting team can locate the fire, as well as any potential victims, faster. Despite dense smoke, hose streams can be visualized with the TIC, allowing firefighters to extinguish the fire more rapidly and reducing the threat to the ship and its personnel. Firefighters will also be able to navigate dangerous spaces more safely. Cargo ties, steam lines, electrical conduits, engine room equipment, and a host of other obstacles will be visible with the TIC. This can help in low-light environments, not just smoke-filled ones.

The logistical challenges of fighting a large ship fire can be overwhelming. Plan to have multiple TICs available to support accountability and ensure as many firefighters as possible can see and navigate. If you are engaged in an interior attack on a fire below the main deck, the danger and challenges are multiplied. Station one firefighter, equipped with a TIC, along the hoseline paths to help guide the crews as they make their way toward the seat of the fire. This is extremely important at any point along the path where a change in direction occurs.

Let’s face it: Pump testing is a long, arduous, and thankless job that has to be done on a regular basis.

While many fire departments perform this task on a yearly basis on their own, often using a training facility with a pump test pit or heading to a surface water source, other departments opt to have a mobile pump testing company come to their locations and pump test apparatus in their home stations.

Pump Testing Units

Gary Weis, chief operating officer of Weis Fire & Safety Equipment and inventor of the Draft Commander 3000 A/T Mobile Fire Pump Testing and Training Unit, says many pump test pits installed at training facilities years ago are now obsolete. “Some fire pumps today perform at 2,000 gallons per minute (gpm), and a lot of those older pits won’t function at that rate,” Weis says. “Also, the water in those pits often is dirty from runoff and sediment, which can allow grit and other solids to get into the pump, damaging it by sandblasting the interior. Our Draft Commander pump tests only with clean water that we recycle.”

The Draft Commander has a 3,000-gallon T-shaped reservoir made of one-inch polypropylene that is attached to a heavy-duty DOT-rated transporter so it can’t twist or flex. The drafting pit section of the reservoir has four antiswirl plates and a water temperature gauge to monitor the water temperature. The Draft Commander is fitted with drafting tubes and swivels, hard suction hose, aluminum inlet manifolds for flowing water and pitot gpm readings, a pump testing monitor station, a handheld monitor, and storage areas for hose and equipment.

Weis says many of the problems he sees during pump tests can be traced back to maintenance issues. “When we perform pump tests, we have numerous tank-to-pump valves leak,” Weis says. “Also, a lot of discharge valves leak. People don’t realize the wear and tear that valves take, and we also see pump seal rings wearing out from getting sand and grit in them. We have a 64-point checklist to review during a pump test, and it covers everything from A to Z.”

Dan Kreikemeier, president of Danko Emergency Equipment, says his company makes the Draftmaster Pump Tester and Trainer. The Draftmaster has a 2,400-gallon UPF water tank and can handle pumps with capacities up to 2,500 gpm. The unit has a forced-air water cooling fan system, stainless steel manifold, stainless steel diffuser with a flowmeter, hard suction hoses, adapters, and an operator’s panel-all on a tandem-axle trailer with a 7,000-pound weight rating and DOT trailer brakes.
