How is the fire extinguisher configuration design calculated?

Answer:

1. Determine the type of fire and hazard level in the configuration site. You have already set up a Class A, a dangerous place;2, a class of solid material fire, the protection of its place of fire extinguishers minimum configuration level is 2A, a single bottle protection area of 75 square meters, the maximum protection distance of 20 meters;The adjacent places 3, according to the provisions of article 10.6.0.1 of the fire extinguisher and fire risk grade of the location of the species are the same, can be a floor or fire as a computing unit, you here are set to a fire zone;

Finally, please note the fire extinguisher configuration requirements:1 fire extinguishers should be placed in clear and easy to access locations, and shall not affect the safe evacuation2 fire extinguisher should be set firmly, its nameplate must be outward3, portable fire extinguishers should be installed in the hook, bracket or fire extinguisher box, the top should be less than 1.50M from the ground height, the bottom height from the ground should not be less than 0.15m4. Fire extinguishers should not be located in damp or strong corrosive sites. When set up, fire extinguishers should be provided with corresponding protective measures. Fire extinguishers set up outside should be protected5 fire extinguishers shall not be placed beyond their range of use6, this is the lowest allocation, can only be more than not less, in this premise, ensure that each set point is not less than 2 bottles, no more than 5 bottles

Every kind of fire extinguisher fire rating is not the same, can be found in the fire extinguisher label left, calculated according to 3 or 4 kg ABC dry powder fire extinguishers, fire 2A single fire extinguisher can be calculated level, each set point should be configured number 7.75 / 2 = more than 3.875 rounding should be 4;According to the above calculations, which should be set at least 4 fire extinguishers configuration, each configuration should be equipped with 4 to 3 kg (or 4 kg) fire extinguisher, if you like this with no good, you can also set the 8 configuration, each placed 2 out of 3 kilograms, can packing, good-looking and easy to manage.

According to the room layout and fire extinguisher fire extinguisher set maximum protection distance to determine the number, because they do not know the floor layout so I can't determine that there should be a few settings, press 60*40 rectangular layout, the middle of a corridor to calculate, at least 4 set point.7, calculate each set point fire extinguishing level, 31 / 4=7.75;
