【 Weak current College 】 from fire supervision and inspection of the construction of fire extinguishers configuration correctly

Fire extinguisher refers to in its internal pressure, the filling out of the fire to put out the fire, and can be changed from mobile access to convenient fire. Fire extinguisher is beginning fire extinguishing, and also to the structure is simple, light and flexible, easy to use and widely used in many occasions, is fire combat ideal front line of popularity of fire-fighting tools. Therefore, a reasonable configuration using fire extinguishers, fire suppression, control the beginning fire plays a decisive role.

First, from the fire supervision and inspection of fire extinguishers configuration of fire in day-to-day oversight, we in some units and places often encounter the following situations:

1. fire extinguishers configuration does not meet GBJ140-90 the construction of fire extinguishers configuration design code of request, is not configured according to the design requirements, or do not speak science experience is estimated to be configured, configure the total lack of or configuration of fire extinguishers and fire types do not match.

2. ammonium phosphate fire extinguishers (commonly known as ABC extinguisher) and sodium bicarbonate fire extinguishers (commonly known as BC dry chemical fire extinguisher) applicable fire objects do not know, or to save the economy costs, in A class of solid fuel sites freely configure BC dry chemical fire extinguisher or carbon dioxide fire extinguisher, widespread.

3. fire extinguisher set point is not reasonable, at your ease, or stay in the place is not obvious, no clear sign of the deposit point of the fire extinguishers, emergency access is not easy.

4. lack of daily management system or a system is not implemented, fire extinguisher, feel free to place or artificially purposes, resulting in fire damage. Lack of maintenance of knowledge, not regular checks on fire, and even use is beyond the end-of-life of fire extinguishers.

5, the new acquisition and maintenance of fire extinguishers are not incoming goods inspection. Some units will use a fire extinguisher or after apparent quality issues fire extinguisher is placed in the use of occasions stopgap, meet check.

6, practitioners without fire training, fire extinguisher, common sense knows very little, some even without the use of fire extinguishers. This shows that the use of fire extinguishers configuration and problems outstanding, if not timely corrected, not only failed to achieve effective control of fire in the early days, it actually increases the fire hazards and unsafe.

Second, the correct configuration of fire extinguishers according GBJ140-90 the construction of fire extinguishers configuration design code requirements, fire extinguishers configuration should consider configuring the kinds of fires, fire fighting effectiveness, on the protection of items defaced, set point temperature and the use of fire extinguishers staff quality and other factors.

(A) the classification of fire extinguishers, fire extinguisher under its manoeuvrability species can be divided into: water-foam fire extinguishers, fire extinguishers, fire extinguishers (common with ABC extinguisher and BC dry powder fire extinguishers), halon fire extinguisher (common l211 fire extinguishers and fire extinguisher 1301), carbon dioxide fire extinguishers, etc.

(Ii) in accordance with the applicable fire fire type select the type of fire extinguisher different place fire type is not the same, you should choose the corresponding types of fire extinguishers, fire up control and elimination of the beginning of the purpose of the fire.

(Iii) on the protection of items defaced because of the use of fire extinguishers, both of which are fire-media to varying degrees, to the fire scene of environmental pollution and the protection of items, if after that put out the fire losses greater than the fire itself caused by direct loss, lost fire extinguishing means. So, the choice of fire extinguishers, also consider its fire extinguishing process on the protection of the objects to be defaced fire losses reduced to a minimum.

(Iv) set point temperature different fire extinguishers have different working environments, the ambient temperature exceeds the fire place with a temperature range, the inevitable extinguisher will affect their safe use Jet performance and even forfeiting.

So a fire extinguisher shall be set at the ambient temperature exceeds its temperature range of locations, under specific environmental conditions of work of fire extinguishers, fire extinguisher with consistently good the working state, extend its service life.
(5) fire extinguishers configuration requirements

1. the amount of building fire extinguishers configuration/f shall be determined by the corresponding provisions of the surface buildings increased by 30%;

2, place with fire hydrant systems, fire extinguishers configuration number can be reduced by 30%; the place is equipped with a fire extinguishing system, the number of fire extinguishers configuration can be reduced by 50%; there are fire hydrants and fire suppression systems, fire extinguishers configuration can be reduced to 70%.

3. fuel open stack, a, b, c liquid storage tanks, combustible gas tank of fire extinguishers configuration places, the number of fire extinguishers configuration can be reduced to 70%.

4, a fire extinguisher configuration place fire extinguishers shall not be less than 2. Each set of fire extinguishers should not be more than 5.

5, in the same fire extinguishers configuration must use the compatibility of fire extinguishers, fire extinguishing agent and should try to choose how the same fire extinguishers.

(Vi) fire extinguishers fire extinguisher fire extinguishers configuration of settings is an important aspect of the design. The main settings, including fire extinguishers, fire extinguisher protection required and distance.

Fire extinguisher set requirements mainly has following several points:

1, should be set in the obvious places. The so-called obvious place, in General, refers to the normal channels, including the room's entrance, corridor, entrance hall and stairs, and other locations.

2, should be set for people to have access to (including an unobstructed and collision).

Set of 3, fire extinguishers shall not affect the evacuation.

4. in a large room or line-of-place by obstacles should set clear signs.

5. fire extinguishers should be set. Portable fire extinguishers (including settings when attachments extinguishers) to prevent falls and other phenomena; trolley-type fire extinguishers are not set in biasSlope and soil not sturdy place, so as to avoid the fire extinguisher cannot normally use or accident.

Nameplate of 6, fire extinguishers must be out, so that when used can directly see the fire extinguisher, main technical performance targets and use instructions, etc.

7. portable fire extinguisher should be set in the hooks, Bay or fire extinguisher boxes and its height is less than the top off the ground, bottom off the ground 1.50m height not less than 0.15m.

8, fire extinguishers should not be set in humid or corrosive.

9. set the outdoor fire protection measures should be taken.
