What kind of water is fire water? What is the difference between fire water and tap water?

Fire water is tap water, but it is not the same as water pipes, the two are separated, even if there is a large area of water outage, the fire hydrant.

When I opened it, there was still water running inside.

Because the dry fire hydrant has not been opened for a long time, the water contains more impurities and bacteria, so the water in it is inedible.

Fire water, not edible.

Fire water, do not touch.

It is everyone's responsibility to take care of public property.

Keep away from firefighting equipment.

Strive to be a civilized person!

China's firefighting water is mainly domestic drinking water, and the Code for Fire Protection Design of Buildings stipulates that "firefighting water can be supplied by water supply pipe networks, natural water sources or firefighting pools." But it's best not to catch water from a fire hydrant to drink!

The main consideration is the health problem, fire pipes, pipe fittings generally do not need to meet the water sanitation standards related to Qin, there are many factors will affect the water quality.

Extended Materials. 1. Safety protection.

The biggest technical problem of the above water as a fire water source is the safety protection problem. In the general design, domestic water is used as the water source for fire fighting, and domestic water and fire water can be connected through pools, tanks or pipelines. However, when reclaimed water is used as a water source, in order to ensure the safety of domestic water, the fire protection system and the domestic water supply system shall not be directly connected.

2. Water quantity guarantee.

The volume of the pool built with reclaimed water or circulating cooling water and fire water must meet the water storage requirements of the building design fire protection code and the water requirements of the reclaimed water and circulating cooling water systems. In addition to meeting the needs of reclaimed water and circulating cooling water systems, the pool water supply pipe must also ensure the water supply requirements for the fire protection system specified in the fire protection code.

3. Pump room design.

When the fire resistance level of the reclaimed water and circulating pool pump room meets the requirements of the fire code and there is a direct outdoor safety exit, the fire water pump room and the reclaimed water and circulating pool pump room can be built together, but they should be separately furnished for operation. When the conditions do not meet the fire protection requirements, the fire pump room should be built independently.

Fire water is mainly used for emergency fire accident treatment, there is a special water supply system, fire water and our domestic water water pipeline line is not the same line, there is a special valve switch management!

Each floor of each mature complex is equipped with a fire protection system, a dedicated water supply system, and a fire station!

According to the specification, the fire water shall meet the following requirements:

1.Municipal water supply, fire pools, natural water sources, etc. can be used as fire water sources, and municipal water supply should be used.

2.Rainwater clear water pools, reclaimed water clear water pools, water features and swimming pools should be used as backup fire water sources.

1. The definitions are different.

In the practical sense of fire fighting, all water bodies that can be used to fight fires can be used as fire fighting water; Tap water refers to the water produced after purification and disinfection by tap water treatment plants, and meets the corresponding standards for people's life and production.

2. The role is different.

Fire water is the water used to extinguish fires; Tap water is water used by people in their lives and production.

3. **Different.

Tap water mainly draws rivers, lakes, groundwater and surface water through the water intake pumping station of the water plant; Fire water can not be regarded as a separate water, fire water has always come from the most convenient water source, there are pools, rivers, lakes and seas nearby, sometimes it is tap water, as long as it can meet the water supply requirements of fire fighting.

China's fire-fighting water is mainly domestic drinking water, which is contrary to the current situation of lack of water resources in China, and how to find a new safe and sufficient fire-fighting water source to replace domestic drinking water is a top priority. From the perspective of saving water and ensuring the safety and reliability of fire-fighting water, reclaimed water, circulating cooling water and rainwater can all be applied in fire-fighting facilities.

China is a country with very scarce freshwater resources, and its per capita water volume ranks 88th in the world, which is only 1 4 of the world's per capita water volume. Eighty per cent of China's cities are short of water, and 110 of them are severely deficient. Beijing, for example, has less than 300 m3 of water per capita per year, similar to Israel in the desert.

China's fire-fighting water is mainly domestic drinking water, and the water quality requirements for fire-fighting water are not as high as that of domestic water, which causes a great waste of domestic water.

Fire water is clean water. China's fire-fighting water is mainly domestic drinking water, and according to the regulations, fire-fighting water can be supplied to the Fuchang water pipe network, natural water sources or fire-fighting pools.

supply, but not from the hydrant.

Drink with water. Mainly considering the issue of hygiene, fire pipes and pipe fittings do not need to meet the water hygiene standards judged by the Drinking and Upgrading Department, and there are many factors that will affect the water quality.

Technical measures: Rainwater as a natural water cycle.

Through reasonable planning and design, take corresponding measures, urban rainwater can be used as fire water. This can not only alleviate the contradiction of water supply in urban water noise to a certain extent, but also effectively reduce urban surface water runoff, reduce flood control investment and disaster prevention losses. Cities can build facilities such as interception dams and regulating ponds to store urban rainwater runoff in a centralized manner, so that it can be used for fire protection or urban miscellaneous water after treatment.

The fact that water can extinguish a fire is determined by a combination of the physical and chemical properties of the water and the conditions under which the fire burns.

1. Water is not a combustible substance;

2. The chemical properties of water are stable;

3. After water and fire come into contact, it can absorb a large amount of heat in the fire, so that the temperature of the burning substance can be lowered below the ignition point and extinguished;

4. The combustion of fire needs an ignition source and an accelerant, and under natural conditions, the oxygen in the air is the accelerant, and the water can isolate the air well.

There are three necessary conditions for combustion: combustibles, combustibles, and the temperature reaches above the ignition point. Water extinguishing has the effect of lowering the temperature and isolating combustibles at the same time.

Water is non-flammable and cools down.

Because when the flame is immersed in it, the water blocks the contact between the combustible material and the oxygen, and the flame is naturally extinguished.

It depends on what kind of fire it is, and not all fires can be extinguished.

Why do you say water can extinguish fires? Although the law is the law, the law of nature.

Summary. The main water used for firefighting is domestic drinking water.

The main water used for firefighting is domestic drinking water.

Chinese name fire water foreign name fire demand nature The water required to extinguish the fire is used for the calculation of outdoor fire fighting water**Reclaimed water, rainwater, circulating cooling water.

In the practical sense of fire fighting, any water body that can be used to fight fires can be used as a fire water source. The Code for Fire Protection Design of Buildings stipulates that "water for fire protection may be supplied by a water supply network, a natural water source or a fire pool.

Does it contain chloride ions?

Hello. It contains chloride ions.

The fire-fighting water is used directly after simple treatment and purification of sewage. Domestic water needs to go through multiple processes to precipitate the impurities in the reed chain calendar, and also accompany the search to purify the bacteria inside. Therefore, the treatment process is more complicated than that of firefighting water, and it is also more stringent.
