Weekly inspection and testing consists of visual inspection of oil and fuel levels and fire pump components, including the controller. A function test of the fire pump, driver and starting systems should be conducted. The fire pump should run for a minimum of 10 minutes for electric motor drivers and 30 minutes for other drivers. 

The commander of the plant fire brigade sent a team member to the fire pump house. The electric fire pump was inoperable due to the power outage. One diesel fire pump was known to be impaired due to mechanical problems and other diesel fire pump had failed to start because its batteries were dead. Several maintenance personnel were sent immediately to repair this diesel fire pump. 

Last maintenance check of No. 2 diesel fire pump and the electric fire pumps. Test run of 5 minutes, (maintenance records)... 

AM. Fire brigade member reaches pump house and finds electric fire pump inoperable due to power failure, one diesel fire pump inoperable due to known mechanical problems, second diesel would not start due to dead batteries calls for maintenance help. Several maintenance employees dispatched to repair diesel fire pump No. 2. 

Water pressure is a key consideration in terms of the adequacy of application and system operation and maintenance. While some domestic supplies have high pressure systems, most are in need of pressurization, as is water from bodies of water and tanks. Fire pumps are routinely used, most often in multiple installations with different means of power drive (e.g., electric, diesel, or steam). When fire pumps operate at high pressures, there is the potential for leaks and line fracture. Periodic maintenance, including hydrostatic testing, will help minimize the potential for such failures. 

Water supplies for sprinkler systems can be provided by public or private systems, or a combination of both. In both instances, it is customary to also provide for a fire hose flow allowance. This allowance is particularly important with fire control sprinkler systems. Public systems can be augmented with fire pumps typically powered by a diesel or electric driver. Private systems are usually supplied by automatic fire pump(s) taking suction from a tank, reservoir, or natural body of water such as a river. The water supply should be capable of meeting the hydraulic requirements of the sprinkler system, have an adequate duration, and be considered reliable. In some cases, it may also be necessary to have two sources of water to improve the reliability of the system. This is particularly relevant in areas having an unreliable public water supply. Fire pumps should be automatic starting. If a reliable electrical supply is not available, a diesel driven fire pump should be used.

Loss of electric power can directly threaten personnel safety. Industrial processes that present a hazard when without power are one example. Emergency power is also needed to operate elevators, fire pumps, fire alarms, communication networks, and other safety-related equipment.

The three drivers recognized by the NFPA code on fire pumps are diesel, electric and steam. The diesel fire pump is the preference of most insurance companies. They have a long history of satisfactory service. These units tend to be more expensive especially when they are used with vertical turbine pumps. With vertical turbine pumps, they require a right-angled drive which significantly increases the cost. They are self-contained and do not depend on outside utilities. 

Fire pump supervision should include pump running and room temperature checks on all pump installations. For electric pumps, the supervision should include power failure and phase reversal. For diesel pumps, supervision should include engine trouble and switch-not-in-automatic-position detection. There are many other common and uncommon supervisions available. 

Main fire pumps should be automatically controlled to start whenever there is a demand that reduces system pressure below a set point of say 7 barg. They should be large enough to keep the pressure above that set point at the most distant hydrant and at the system design flow rate. Spare pumps should be diesel engine driven with independent fuel tanks. Where steam is available, steam-driven pumps may be used to supplement the electric- and diesel-driven units. 

Storage areas for maintenance, janitorial, and other service organizations must be provided. Safety items such as fire extinguishers, firehose cabinets, safety hoops on permanent ladders, guard rads, shielding for acid pumps, clearance for electric panel boards, etc, are needed. Manholes and cleanouts for sewer pipes within the facility as well as in the landscape and parking areas should be provided. 

In extremely cold environments, engines can quickly become difficult, sometimes nearly impossible, to start. If ordinary gasoline- or diesel-oil-fired heaters are used, the coolant circulation pump, air fan, etc, must be powered from the vehicle s batteries, thus curtailing the time the system can be used, especially at very low temperatures when it is needed the most. By adding PbTe thermoelectrics to such heater systems, about 2% of their thermal output can be turned into electricity to mn the heater s electronics, fuel pump, combustion fan, and coolant circulation pump, with stiH sufficient power left over to keep the vehicle s battery fliUy charged. The market for such units is in the hundreds of thousands if manufacturing costs can be reduced.
