Which of the following is the main concern of fire departments regarding water treatment facilities?
the fire department's main concern regarding treatment facilities is that: maintenance failure or other events could disable pumping station(s) or severely hamper the purification process.
What are the three main means of moving water used by firefighters?
Most firefighters understand that there are three types of water mains: primary feeders, secondary feeders and distributors. Primary feeders are large pipes that transport large quantities of water from the pumping station to the distribution system.
What is the minimum recommended pressure for water coming from a fire hydrant?
20 psiThe minimum fire flow from any individual fire hydrant shall be 500 gpm. The minimum flowing pressure at maximum flow shall be 20 psi.
What are external parts of most fire hydrants made from?
The hydrant bonnet is usually made from the same material as the barrel. The valve stem in a dry-barrel hydrant design is steel. The valve stems in a wet-barrel hydrant are usually made from silicon bronze. The hydrant outlets are molded in bronze.
What is in the water firefighters use?
Class A foams are used to lessen the surface tension of water, which improves the wetting and saturation of water used to fight Class A fires, which are fueled by ordinary combustibles.
What do firemen do with water?
Using water is one common method to extinguish a fire. Water extinguishes a fire by cooling, which removes heat because of water's ability to absorb massive amounts of heat as it converts to water vapor. Without heat, the fuel cannot keep the oxidizer from reducing the fuel in order to sustain the fire.
What is the recommended minimum pressure for water coming from?
Residential water pressure tends to range between 45 and 80 psi (pounds per square inch). Anything below 40 psi is considered low and anything below 30 psi is considered too low; the minimum pressure required by most codes is 20 psi. Pressures above 80 psi are too high.
What is the recommended minimum pressure?
Most passenger cars will recommend 32 psi to 35 psi in the tires when they're cold. The reason you check tire pressure when they're cold is that as tires roll along the road, friction between them and the road generates heat, increasing both the temperature and the air pressure.
What is the minimum pressure in a water distribution system?
Water pressure is an important factor to consider when planning a distribution system. As a rule of thumb, the water pressure throughout the distribution system should be no less than 17 PSI.
Why are fire hydrants used?
Used by firefighters during a fire to put out the flames, fire hydrants operate by allowing your local firefighters to quickly tap into your water utility's pressurized water system. The firefighters remove a nozzle or two, fasten hoses to the nozzles and turn the valve to get the water flowing.
What is fire hydrant system?
Fire hydrant installation consists of a system of pip work connected directly to the water supply main to provide water to each and every hydrant outlet and is intended to provide water for the firemen to fight a fire. The water is discharged into the fire engine form which it is then pumped and sprayed over fire.
What is fire hydrant and its use?
Hydrants are devices for extracting water from pipelines and water distribution systems. In the event of a fire outbreak, a fire hydrant can assure fast water supply. The connections to the pipes are tapped with so-called hydrant wrenches and hydrant standpipes and are further connected to the fire trucks.

Why did the Sandoz spill happen?
The Sandoz chemical spill of 1986, for example, turned the Rhine river red with pollutants and affected much of the wildlife in the river due to faulty containment of firewater used in treating a agrochemical warehouse fire. The 30 tons of toxic chemicals released into the river was due to a lack of firewater retention.
Why is fire water considered a pollutant?
Firewater is often associated with pollution because of its rapid ability to spread hazardous water when used for firefighting and incorrectly contained , and firewater runoff is often the culprit or a main contributor to many chemical spill pollution events (Related: Water pollution ). The Sandoz chemical spill of 1986, for example, turned the Rhine river red with pollutants and affected much of the wildlife in the river due to faulty containment of firewater used in treating a agrochemical warehouse fire. The 30 tons of toxic chemicals released into the river was due to a lack of firewater retention.
What is firewater containment?
Firewater containment is the process of containing (firewater) the run-off from fighting fires. Firewater contains many hazardous substances, which are the by-products of combustion, which normally turns safe materials into toxic, polluting and environmentally damaging substances. The preferred method of firewater containment is to use pneumatic bladders/drain stoppers that block the outflow from the drain or pneumatic non-return valves, both of which can convert the drains into containment vessels (called sumps) from which the firewater can be pumped away into tankers for safe disposal.
Why does fire damage the environment?
Often, damage to the environment following a fire at an industrial site occurs because of polluted firewater runoff. This happens when the water used in treating a fire picks up contaminants from the burning object and leaks into the surrounding environment when poorly contained.
What is the best way to contain firewater?
The preferred method of firewater containment is to use pneumatic bladders/drain stoppers that block the outflow from the drain or pneumatic non-return valves , both of which can convert the drains into containment vessels (called sumps) from which the firewater can be pumped away into tankers for safe disposal.

What is the bad news about firefighting?
The really bad news is that under fire-fighting conditions, pressures push engineers to solve problems not just inefficiently but badly. They don’t work on a problem long enough to uncover its root cause—they just make a gut-feel diagnosis. Then, instead of testing their hypothetical diagnosis offline, they introduce a hasty change in the process. And if the quick fix doesn’t solve the problem completely (it is usually unclear whether it helped or not), they leave it in place and try another solution. They don’t solve the problem because they don’t take the time to approach it systematically.
What is incomplete solution?
Solutions are incomplete. Many problems are patched, not solved. That is, the superficial effects are dealt with, but the underlying causes are not fixed. Problems recur and cascade. Incomplete solutions cause old problems to reemerge or actually create new problems, sometimes elsewhere in the organization.
Can a set of principles prevent fires?
But a set of principles can actually prevent most fires . In business organization, there are invariably more problems than people have the time to deal with. At best, this leads to situations where minor problems are ignored. At worst, chronic fire fighting consumes an operation’s resources.
Can tactical methods be put into effect quickly?
Tactical methods can be put into effect quickly without making high-level policy changes. Although some of the methods are culturally difficult in U.S. companies, many are simple to apply once a company recognizes the dangers of fire fighting.
