The distance between the box and the other must be 50 m.
Also, the tavernes are on a continuous basis with firefighting pressure.
Fire extinguishers in the water.
Water cartridges are used for easy treatment and rapid response, and no special expertise needs to be dealt with, but no one can use them with little training and explanation. There are two water supply systems to feed these batteries:
1. Dry tube system
The water supply system is dry and fed by civil defence personnel from their portable tanks via a fast-track link (civilian defence compass 4; ii5; ii5); ii) at the supply list wall.
Pharaohs are taken from the supply list and boarded on every branch of a fast-track emergency lockup 2.5 âa âa âa âa âa âa âa âa âa âa
The incarceration shall be installed for a maximum of two floors, and shall also board a locker at the entrance to the building or building with more than one entrance to be installed at each entrance, as well as on the rooftops of the buildings at each stairwell.
A trained individual takes a fast-track hose in one side and a boat with a water launcher at the other end and fires.
2. Wet tube system:
The water feeding network shall be full of water, either by connecting it to the city ' s public network, by high treasury or by a firefighting pump group drawn from a tank with a capacity of 30 minutes at a minimum.
If the building isn't less than 10 km away from the civil defence site, if the distance goes up 45 minutes or 60 minutes, and no one disagrees on the tank site, and I'd rather be.
Earth and out of the building, and it eases water supply from moving tanks and tanks on another subject.
fire hoses, linked to supply lists, are installed on the wall or are buried in the wall at the entrances of the building, on the stairwells, on the roof or at a place accessible to all, and are easily transported by the hose to the farest point unhindered.
Firefighting cartridge boxes are used as the fastest firefighting tool in case water machine guns don't respond.
Sprinklers and fireboxes are always sown in any fire project for a building.
Important requirements for water supply lists, fire boxes and emergency entries:
1. Pressure in the network extending emergency valves and fire hoses shall not exceed what is specified.
2. The rise of the emergency valve from the surface of the peace zone ranges from 900 mm to 1500 mm measured from the surface of the peace zone.
3. An emergency valve is installed for every two floors on many and favourite valve per staircase.
4. An emergency valve shall be installed on the roof of the building, the footprint and the entrance to the building.
5. A nutritional list is installed for each drawer.
6. In the case of the installation of two nutritional lists at the one-tier house, they shall be connected from the bottom of a civilian defence compass 4 02 05 / 2.5 / 2,5 / and also arrived from the water source if the building ' s water tank is found above the building.
7. The non-result valve is installed with the civil defence link mentioned.
8. Qatar is the nutritious emergency reserve at least 6 (150 mm) and can be overtaken by 4 (110 mm) if local authorities are satisfied with hydrolytic accounts.
9. Operational pressure at the end of the hose launcher at the end of Khartoum according to the Khartoum country:
Khartoum diameter 65 millimetre/operating pressure: 3.5 bar
40 mm / operational pressure 3 bars.
19 – 22 millimeters/, 3 bars if the launcher diameter is 4.5 mm, while operating pressure is 4.5 bars if the launcher ' s opening is 6.4 millimeters.
10. The upper limit of automatic pressure at the point of contact of the fire hose measuring 40 millimetres or 65 millimetres with the feed list is: 12.1 bars and 6.9 bars, respectively, while 5 bars for the 19th and 22 millimetres.
11. If the pressure of the network is increased from the corrosive pressure pressure of the network, the pressure valve is installed to reduce pressure to 11.4 bars or 5 bars depending on the diameter used, and it takes into account the lack of pressure from the control over the valve value.
12. Minimization of firewater flow rates through Khartoum:
Khartoum / diameter launcher/flux rate per minute:
65 mm/19 mm / 473 litres per minute
40 m/ 12 mm/ 189 LLF
25 mm/ 4,8 mm / 30 LLF at 3 bar operational pressure
19 m/ 6,4 m/ 30 LLF, at operating pressure of 1,25 bars
Area covered by one Khartoum (the trunk of fire hose according to country and degree of risk):
Hazard category/ Khartoum / square metre area
Low: 1925 mm/ 800 square metres
Regular ES: 19, 25 m/ 600 m2
High: 40 mm/400 square metres
