Departments are mounting cameras as backup, side-scanning, and front-recording devices on fire apparatus as well as in specialty areas of fire vehicles such as the tip of an aerial or the top of an aircraft rescue and firefighting (ARFF) rig.

Dino R. Nama, vice president of technical services for Intec Video Systems Inc., says Intec manufactures a broad line of industrial camera systems and components and has been putting cameras on vehicles since 1980. "We've been selling to the fire industry for 20 years now," Nama points out, "but back then, the cameras were not used to the extent they are today. Cameras on fire trucks really took off about five years ago."

Camera systems installed on fire apparatus are used primarily for blind spot observation, Nama says, whether for rear vision, side vision, or forward vision for the vehicle's operator. "Fire departments are using it a lot for rear and side vision, with the side-vision cameras used for lane changes, monitoring placement of aerial jacks, and even for improved views for tiller operators," he points out. "In terms of front vision, an operator might use a camera for a better view if he has an overhanging platform. On tenders, operators use cameras to monitor water discharges."

Nama says Intec promotes its AH series of cameras for the fire industry, which the company considers a relatively light-duty application when compared to some of the industrial camera products it makes. "If fire departments want a camera for extreme applications, we make our XL product line, which is a high-end, fully waterproof, and fully submersible unit that is built to withstand extreme vibration," Nama notes.

Joe McCleary, senior account executive for Safety Vision, says his company makes backup and side-looking cameras, as well as thermal imaging units that can zoom in on a specific location on a fire scene and record what is happening. "All of our cameras connect via cabling to a DVR recorder, which does the recording, and also connect to monitors so incident commanders have a live look and can respond accordingly to situations."

Peter Plate, director of sales and marketing for Rosco Vision, notes his company makes back- and side-viewing camera systems, as well as windshield recording devices, mirrors, and sun visors, all of which are installed by original equipment manufacturers. "We are now seeing a convergence of technologies where mirrors and cameras are becoming one product where the camera is used for side

I also believe it is worth much more than the sum of its parts because without it, firefighters could not put out fires, save lives, and protect property. That is why I believe it should be held in venerable status and be kept in tip-top shape.

This article will cover basic fire pump types in use today, pump maintenance, common problems, key components, and testing required by National Fire Protection Association (NFPA) 1901, Standard for Automotive Fire Apparatus, which establishes that pumps must be able to flow rated capacities.

Pumps are rated by gallons per minute (gpm) or liters per minute. The pumps are to be tested at 150 pounds per square inch (psi) at 100 percent of rated capacity, 200 psi at 70 percent of rated capacity, and 250 psi at 50 percent of rated capacity. Additionally, there is another test required by NFPA 1901 that is called the Pumping Engine Overload Test for 750-gpm or larger pumps that consists of pumping at 165 psi for rated capacity at net pump pressure for at least five minutes. Basically, if your rig's engine, drive train, and fire pump pass this rigorous test, then the pump is in great condition. This test should be performed right after the 150-psi 100 percent of rated capacity test. These tests should also be performed annually, which is required by NFPA 1911, Standard for the Inspection, Maintenance, Testing, and Retirement of In-Service Automotive Fire Apparatus.

Pump Types

There are several different types of pumps in the fire service today with various drive configurations that depend on the output ratings of the pumps and the type of firefighting they are specified for. Regardless of the type of pumps you have on your rigs, they require proper care, maintenance, and testing to ensure long and trouble-free lives.

The most common type of fire pump used by the United States fire service today is the centrifugal pump, which is available in both single-stage and multistage versions. Both are nonpositive displacement pumps with main components consisting of an impeller mounted on a shaft housed inside a casing.

The centrifugal pump is a nonpositive displacement pump because unlike a piston-type pump, it does not pump a specific amount or volume of water with each revolution. It works on the basic principle that as water enters the center of the impeller (eye) as it rotates, the water is flung outward by velocity, and the faster it rotates the greater the pressure it creates. Which type is better when considering single-stage vs. multistage is still debated to this day. However, multistage pumps can develop higher pressures than the single-stage or single-impeller pumps, and they allow the pump operator to select either volume or pressure modes depending on firefighting needs. Selecting pump type and size basically boils down to preference and a department's needs based on the structures it protects.

The pump operator or driver is the most important person tasked to ensure the fire pump is properly maintained. I consider this person to be the first line of defense in keeping the pump in top condition. He should operate and test the pump on a daily basis and follow the pump manufacturer's published maintenance checklist. He should exercise all valves and pump controls and keep the valve oper

However, these incidents are termed backover crashes and can result in severe outcomes. Backover crashes predominantly occur in off-road areas such as driveways and parking lots. On average, there are 210 fatalities and 15,000 injuries per year caused by backover crashes.

New Federal Rules for Rear Vision

In March 2014, the National Highway Traffic Safety Administration (NHTSA) issued a final rule requiring an expanded field of view behind any vehicle with a gross vehicle weight rating of 10,000 pounds or less. In the final rule, the NHTSA expressed its belief that by promulgating the new requirement, backover crashes involving children, persons with disabilities, the elderly, and other pedestrians would be reduced significantly. Approximately 58 to 69 lives are expected to be saved each year once the entire on-road vehicle fleet features rear visibility systems meeting the requirements of the new rule. The Fire Apparatus Manufacturers' Association (FAMA) joins with the NHTSA in encouraging safety during backing maneuvers through the proper use of spotters as well as installing rear vision technologies.

Emergency Vehicles Need Special Attention

Passenger cars or light vehicles generally have more visibility to the rear of the vehicle than do large emergency vehicles. For this reason, it is important to consider auxiliary systems such as backup cameras when specifying apparatus. Emergency vehicles may be placed in positions where there are pedestrians; bystanders; and, of course, emergency service providers. There may be adverse conditions that further complicate being able to see rearward of the vehicle-heavy smoke, heavy downpours, heavy snow, and so on. Both National Fire Protection Association (NFPA) 1500, Standard on Fire Department Occupational Safety and Health Program, and NFPA 1451, Standard for a Fire and Emergency Service Vehicle Operations Training Program, require fire departments to train on and use a spotter to signal to the driver when backing the vehicle.

Mirrors Leave Blind Spots

Mirrors installed on emergency vehicles do not give complete visibility directly behind the vehicle. There is still an area that is considered a blind spot. When using a spotter, even in the best of conditions, the spotter could move into that area. Should the driver continue to move the vehicle, an accident could occur. In December 2012, a firefighter was killed when acting as a spotter for a fire apparatus. Rear vision technologies may be able to lessen the risk to spotters as well as to other bystanders.

The NHTSA has conducted research on heavier vehicles, similar to what it conducted to support the aforementioned final rule. It studied cross-view mirrors as well as rear-view cameras. Although it found using cross-view mirrors reduced the number of backover crashes, it found that using backup cameras potentially helps reduce instances of such crashes even more.

Rear Vision Technologies Worth the Price

Adding a backup camera system to an emergency vehicle certainly comes with a cost. Depending on the system and how it is tied into other vehicle systems, the cost will vary. However, as we all know, technology is ever-changing. With the new mandate for expanded fields of view in smaller vehicles, technology will certainly advance while the cost of such systems may come down over time. Considering the risks that can be mitigated or accidents that could be avoided by using a backup camera system, the cost of such a system seems well worth it.

Backing a vehicle, by its nature, can be more hazardous than driving forward. Every vehicle has blind spots, but the larger the vehicle

The modern fire station is a very specialized facility, not just a garage in which to keep big trucks. The most pronounced change in station design during the past 40 years is also the most obvious-construction costs.

In the 1970s, an average fire station construction cost was $50 to $60 per square foot. Today, the average cost is $190 to $250 per square foot, with much more volatility over the past decade.

Volunteer departments transitioning into combination or career departments have changed the spaces in their stations. Post-transition, these stations have needed sleeping quarters, toilet and shower rooms, and daily-use kitchens. Even something as simple as where firefighters park their personal vehicles and enter the building is affected by volunteer or career status.

Colocating Public Safety Agencies

As municipalities have sought ways of providing better, all-around public safety coverage, and as departments or agencies have looked for ways to share the ever-increasing construction costs, colocation of multiple public safety agencies into one facility has steadily increased. Securing different portions of the building for multiple occupants then becomes a serious design consideration.

When the second occupant is emergency medical service (EMS) personnel, there are often separated sleeping quarters to keep one set of responders from waking the other set with its calls. There are also dedicated EMS supply rooms. Sometimes there are even separate dayrooms and kitchen facilities for the two groups.

When the second occupant is law enforcement, the line of separation is usually more pronounced. More commonly you will have the fire department on one side, police department on the other side, and shared spaces in the center of the facility. Additionally, the law enforcement component is frequently a simple satellite presence comprising a single office and separate toilet. Often these satellite stations are not staffed continuously.

GOVERNMENTAL Regulations

The regulatory changes of the past 40 years more severely impact the design of the facility. It seems that these regulations increase yearly. The "essential facility" building code classification requires a more rigidly constructed structure than ever before encountered by public safety. For example, over the past two decades, fire sprinklers began to be required in sleeping quarters and are now quickly becoming mandatory in all spaces. The Americans with Disabilities Act (ADA) of 1991 applies to both public and private areas of a station. Elevators and handicapped facilities have become increasingly present in stations because of the ADA. Regulations regarding storm water retention and quality, landscaping, and oil separation for vehicle drainage areas have added to site sizes, requirements, and costs.
