How many dry chemical fire extinguishers are configured for each bus

1. Determine the fire type and danger level of the configuration site, and the danger level of the office with electronic computers, photocopiers and other equipment should be determined as medium hazard level (if it is an office in a super high-rise building or a class of high-rise building, it should be determined as a serious danger), if you don't make it clear, then I will use it as a medium-risk fire place;

2. Office fires are mostly Class A solid matter fires, and the minimum configuration level of a single fire extinguisher in the protection place is 2A, the protection area of a single bottle is 75 square meters, and the maximum protection distance is 20 meters;

3. According to the Article.

provisions. For adjacent places where the danger level and fire type of the fire extinguisher are the same, a floor or a fire partition can be regarded as a calculation unit, and the floor can be regarded as a fire partition;

4. You did not specify whether the office was equipped with fire hydrants and sprinkler systems, and I assume that the correction factor is 1 when there is no calculation;

5. The minimum fire extinguishing level of the calculation unit is: the protection area divided by the maximum protection area of the unit fire extinguishing level multiplied by the correction coefficient 1000 75 1, and the larger integer is 14;

6. Determine the number of fire extinguisher setting points according to the room layout and the maximum protection distance of the fire extinguisher, because I don't know the floor layout, I can't determine how many setting points there should be, according to the 40*25 rectangular layout, a corridor in the middle to calculate, at least 2 setting points are needed.

7. Calculate the fire extinguishing level of each set point, 14 2=7;

8. The fire extinguishing level of each fire extinguisher is not the same, which can be found in the lower left of the fire extinguisher label, calculated according to the general 3 kg or 4 kg ABC dry powder fire extinguisher, and the fire extinguishing level of a single fire extinguisher is calculated as 2A, and the number of each setting point should be 7 2 The remaining rounding should be 4;

According to the above calculations, the office should be set up at least 2 fire extinguisher configuration points, each configuration point should be equipped with 4 3 kg (or 4 kg) dry powder fire extinguishers, but it is not easy to put this match, so you can set up 4 configuration points, each put 2 3 kg of 3 kg, can be packed, good looking and easy to manage.

Finally, please note the fire extinguisher configuration requirements:

1. Fire extinguishers should be set up in obvious and easily accessible locations, and should not affect safe evacuation.

2. The fire extinguisher should be set up firmly, and its nameplate must face outward.

3. The portable fire extinguisher should be set up on the hook, bracket or in the fire extinguisher box, and the height of its top from the ground should be less.

The height of the bottom from the ground should not be less.

Fire extinguishers should not be installed in wet or strongly corrosive locations, and when they must be installed, they should have corresponding protective measures. Fire extinguishers installed outdoors should have protective measures.

5. The fire extinguisher shall not be set up in a location beyond the temperature range of its use.
