|| Automatic and fixed systems and equipments for firefighting: |
Is a network of fixed extensions with aperture distributed in the required places that are needed to be protected and it is fed with a continuous source for the necessary fire material. It works automatically due to the sensing of heat that results from fire, or due to the sensing of fire.
|| Automatic water sprinklers system for firefighting: |
Overhead network of pipes spread in higher places to be protected. It is fed from the water source in terms of quantity and pressure, so water can rush through the closed sprayers (wet sprinklers), that opens automatically due to the effect of heat. Or water rushes through the open heads and cover the entire place which opens automatically by a warning help.
|| The automatic network water sprinkler must be designed, implemented and maintained in accordance with the specifications and conditions (Part II) or the guidance of the Civil Defense.|
|| Taken into account in the design of the type of water sprinklers the seriousness of fire as a high, medium, or small risk, in accordance with the specifications and conditions (Part II) or evidence of Civil Defense|
|| Types of automatic water sprinklers for fire extinguishing: |
1 – Humid net.
2 - Dry network.
3 – Wet network with a previous operation.
4 – Network for total immersion.
5 – installed network
|| A wet network of water sprinklers for fire: |
Is a network of pressurized water to rush through the closed heads of the sprinkler that are opened when affected by temperature.
|| The dry network of water sprinklers for fire extinguishing: |
Is a network that have similar extensions of the humid network but with compressed air, and water is suspended at the main valve by air pressure. The valve opens automatically when the air leaks from the sprinkler’s heads that opens when it is affected by heat allowing water to rush through it.
|| Wet network of prior operation: |
Is a network with similar extensions to the wet network, where water is suspended at the valve, with a warning network assistant and is dependent upon the water valve, added the warning to help either by air or by electricity. It also works automatically when affected by fire and opens the valves allowing the water to rush in the net then through the thermal sprayers that in their turns open when affected by heat.
|| The total immersion network: |
Is a network of similar extensions to the wet network of prior operating, but the heads of the sprayers are all open, immersing the entire site during the operation of the system.
|| Installed network:|
Is a common system between the wet network of prior operation and that of the dry network.
|| The helium system or its alternatives: |
it is about a network of pipes distributed in the places that are needed to be protected, and it is fed by a cylinder that contains helium gas or any alternative to it (extinguisher) and it is stored under the pressure of nitrogen to rush through the nozzles to the place that needs protection when the system is on, knowing that the helium system is going to be internationally banned due to its affect on the environment, and there is going to be alternative materials to it.
|| Carbon dioxide system: |
it is a network of distributed pipes in the places that are in need of protection, and it is fed by cylinders containing carbon dioxide gas (as an extinguisher) that is stored under pressure in order to rush through the nozzles that are distributed in the necessary places when the system is on “according to the terms of the civil defense’.
|| Dry chemical powder system: |
it is a network that is distributed to the places that need protection, and it is fed from the dry chemical powder vessels (as an extinguisher). It is pressured due to nitrogen or carbon dioxide to rush through the nozzles to the meant location. The materials that are used in extinguishing consist of sodium bicarbonate, potassium, or mono ammonium phosphate.
|| Types of dry chemical powder: dry powder systems are divided into the following types according to the way of coverage: |
1 - total immersion system: a system that covers the size of the place or the entire room.
2 - Local immersion system: a system which covers a specific space in the building or location.
|| Operation of the dry chemical powder is as follows: |
1 - Auto start: fire detectors open the valves of the powder containers.
2 – Manual electrical operating by an electrical manual switch that act like the fire detectors.
3 - Mechanical manual operation: by manual mechanical means.
|| Design: the dry chemical powder system must be designed, implemented and maintained in accordance with the requirements and specifications of the civil defense.|
|| Foam and water system: |
A network of pipes spread to the places that need protection, and it is fed from the water and foam source, either mixed together, or are mixed before they flow on the burning surface.
This mixture flows in the appearance of bubbles that form an isolating cover to the outside air away from the burning surface. Then water does the cooling process.
|| Types of foam in terms of expansion: |
1 – Low expanding.
2 –Medium expanding.
3 – High expanding.
|| Types of foam fire-fighting: |
Foam systems are divided according to the way of performance to the following types:
1 - fixed network system.
2 - Generating system (special for the foam system).
|| The fire fighting foam system operates as follows: |
1 - Auto start: by the fire detectors, or through a panel warning for the operation of pumps or other means that pushes the solution.
2 - Manual mechanical operating and it happens by opening the valve of the foam or the mixing systems
3 – Manual electrical operating: The operation of pumps or other means such as the electrical files to open the traps.
4 - Remote control: by prior programming with a TV camera.
|| Design: the fire-fighting systems must be designed, implemented and installed in accordance to the terms and specifications (Part II) or the regulation of Civil Defense.|
|| Fixed automatic units (Modeler Extinguisher): |
They are individual firefighting units installed in the premises that need to be protected. And it works automatically to push its stockpile of material fire at the time of the fire.
|| the distribution, type and size must be appropriate for the purpose of protecting places in accordance with the terms of Civil Defense.|
|| Units must be in accordance with international standards adopted by the Civil Defense.|
|| The units must be provided with regular maintenance by the certified maintenance contractor in accordance with the terms of Civil Defense.|
