In fact, "Ctesibius of Alexandria is credited with inventing the first fire pump around the second century B. But the idea was lost, ironically, in the burning of Alexandria" History of Firefighting". It would then be the Industrial Revolution that would see these pumps advance technologically. Steam pumps were the first motorized pumps, used in the 19th century. By the early 20th century, the internal combustion engine was utilized in fire pumps.
Fire engines, during this time, would have a second motor for the fire pump. In , America saw the first fire engine that utilized a single motor to run both the truck and the water pump. These early pumps quickly replaced the steam-powered pumps that were the predecessor. At first, pistons were used to power the motor.
Soon after, however, rotary power was used, and this was quickly followed by the technological improvement using centrifugal force, where compressed air expels water through centrifugal force. The maximum pump pressure is determined by the speed and size of the engine. This is the model for the modern motorized fire pump, that allowed a higher volume of water and a larger range when fighting fires.
Today, fire pumps have come a long way from the days of hand-pumps used by the Greeks and Romans. Today's motorized fire pumps are high-powered, how volume pieces of machinery that are critical in fighting fires. These fire pumps give a minimum of gallons of water per minute, at pounds per square inch of force "The History".
There is continuing controversy regarding which is better -- single-stage or multiple-stage pumps. Both pumps play important roles in fire fighting; however the choice of which type of pump must depend on the specific pumping requirements. These differences are found in the design of the pumps. The single-stage pumps of today have "one dual suction impeller designed to take water in both sides of the impeller, providing discharge flows to all discharge gates.
The operator has full range pump performance with the operation of the engine throttle. A single-stage pump can reach approximately Psi maximum pressure" "Single-Stage". In contrast, a two-stage pump uses two impellers. These operate side-by-side, on a common shaft. This design allows the operator the choice to select either pressure or volume. This allows them to adjust the pump depending on the unique fire event.
A transfer valve is incorporated into the design of a two-stage pump to facilitate this choice. The design of the two-stage pump allows it to attain higher pressures than their single-stage counterpart. In fact, many two-stage pumps can reach pressures as high as Psi, this is in contrast to the Psi that the single-stage pump maxes out at "Single-Stage".
Choosing the best pump for each situation often is based on their advantages. The single-stage pump offers a significant benefit of simplicity. This makes it a highly reliable pump.

They must also use extreme caution when operating in a truss roof or floor construction, and move with deliberate care and also open immediately all the open ceilings and other concealed spaces if a fire is suspected of being present in a truss roof construction.
The firefighters must also have a charged hose available to them when they require it, under the circumstances. Preventing Injuries and Deaths of Fire Fighters due to Truss System Failures What makes it even worse is the fact that when there is a fire in the truss system, since the truss system is kept well hidden, the fire therein goes unnoticed for long periods of time, and this would result in a loss of integrity.
The fire degrades the structural members, and all firefighters in general rely on the typical warning signs of an imminent structural collapse, like for example, a sagging floor, or a spongy floor, and when the truss system is about to collapse, thee warning signs are not exhibited, and the firefighter remains within the structure, completely unaware that the roof or the floor is about to collapse on him and his team, and this is what happened in the Hackensack firefighting tragedy, where five brave men lost their lives just because they were not aware that the truss roof was about to collapse on them and kill them.
The purpose of the Report is 'lessons learned' after the fire has happened. Sometimes, these reports bring to light certain new knowledge about a fire, and sometimes, the lessons may not be new, but can be brought to one's attention once again due to the extent of the fire and the tragedy surrounding it.
The report helps in researching what went wrong, and at times, this helps in learning more about human behavior during a fire, or even about the types and methods of construction being used at that time, and how they contributed to the fire and its aftermath. These various Reports are usually sent to fire magazines and are also distributed at national and regional fire meetings. The Aftermath of Firefighter Fatality Incidents: Preparing for the Worst They are extremely useful for policymakers who need detailed information on the nature of the fire incident so that they may be able to improve codes and change them wherever necessary, and the Fire Administration sends its team of officers to investigate the incident only after the dust has settled down on the incident.
It must be noted that in spite of the recent emphasis on safety and on health within the fire service across the United States of America, about a hundred firefighters continue to die each year during the course of their duty, while some others become seriously injured. It must be remembered that even though only small percentage of these fatalities occur in actual firefighter incidents, the impact that these casualties will have on the affected fire departments, and on the firefighters and on the department in general is tremendous.
The grieving members of the department, and also the entire concerned community must be made to feel that any operational problems that may have led to the fatality are indeed being addressed in a proper manner, and probably, certain changes must be brought in to the fire department so that such an incident will not occur again. Although the reaction to a tragedy would differ from one individual to another, in most cases, the firefighter will not let a fatality stop him from placing himself in the danger zone again, when it is required of him to do so.
After-action reports are therefore extremely important in dealing effectively with the aftermath of a firefighting fatality incident, and there will be an increased potential of attempting to prevent a similar tragedy from occurring any time in the future. One fact to remember is that every firefighting fatality would inevitably attract a lot of media attention, and this means that the Department must maintain a positive relationship with the media if there is to be fair coverage of the incident.
Preparing for the Worst However, what actually happened in Hackensack resulting in the death of five firefighters may be due to bad supervision, or due to plain human error, or due to mechanical malfunction, or due to any other reason, and this is what happened on that day: No one responded, and this was because, as was found later on, their radio communications had in fact been going out, but were being received on the general channel, which firemen would not listen to.
Fire Service Law Consensus standards are developed by specific industries in order to set forth broadly accepted standards of care and operations for certain practices.
The fire service should be one of the best careers a person should have. Yes it is often a mystery why we running into burning buildings where other people are running out. It is a sense of bravery, determination and will. Firefighters always look forward to “slaying the dragon,” as fire is.
