4. The type of fire extinguishing agent for different types of fire extinguishers configured in the same configuration unit is not an incompatible fire extinguishing agent.

5. The type of fire extinguisher matches the type of fire in its place.

In general places, 4 kg dry chemical fire extinguishers (ABC) are equipped with 1 set every 75 square meters or so, and no less than 2 sets are configured at each point.

Fire extinguishers shall be installed in the public areas of residential buildings. When the floor area of the public parts of each floor of the residential building exceeds 100m2, it is necessary to configure one portable fire extinguisher with 1a; This is the minimum requirement: it is currently possible to implement the benchmark of one 1A portable fire extinguisher per 100 m2.

Precautions. The content of the system is regulated, and the content is checked.

1. Fire extinguishers should be avoided in transportation and storage, such as upside down, rain, exposure, strong radiation and contact with corrosive substances.

2. The storage environment temperature of the fire extinguisher should be in the range of -10 45.

3. The place where the fire extinguisher is placed should be kept dry and ventilated to prevent the cylinder from being corroded by moisture. Sunlight exposure and strong radiant heat should be avoided so as not to affect the normal use of the fire extinguisher.

4. The fire extinguisher shall be inspected regularly according to the requirements and inspection cycle specified by the manufacturer. Fire extinguisher inspection contents:

The outer surface of the fire extinguisher pressure gauge shall not have defects such as deformation and damage, otherwise the pressure gauge shall be replaced;

Whether the pointer of the pressure gauge is pointing in the green zone, otherwise it should be filled with drive gas.

Fire extinguisher. The following requirements are required for the placement of fire extinguishers: 1. Fire extinguishers should be set in obvious and easily accessible locations, and should not affect safe evacuation. Second, the extinguishing mold firearm should be set up firmly, and its nameplate.

Must be facing outward. 3. The portable fire extinguisher should be set up on the hook, bracket or in the fire extinguisher box, and the height of the top from the ground should be less than that, and the height of the bottom from the ground should not be less. 4. Fire extinguishers should not be set up in wet or strongly corrosive locations, and if they must be installed, they should have corresponding protective measures.

Fire extinguishers installed outdoors should have protective measures. 5. Fire extinguishers shall not be set up in locations that exceed the temperature range of their source sullen hail stalls.

The fire extinguisher equipment standard at the construction site is as follows:

1. Temporary construction site, placed according to the square, within an area of 200 square meters, 2-4 need to be equipped. If the area is more than 200 square meters, it needs to be equipped with 5-6 fire extinguishers. With an area of more than 1,200 square meters, every 100 square meters needs to be equipped with two 10-liter fire extinguishers, as well as special Taiping buckets and water buckets.

2. Within 50 square meters of the material warehouse, one fire extinguisher is required. For every 50 square meters of area increase, it is necessary to add 1 firearm to extinguish the front branch, and if there are many combustibles in the warehouse, it will be increased accordingly.

3. Within 100 square meters of kitchen area, 3-4 fire extinguishers need to be configured.

4. The carpentry room and paint room need to be equipped with a fire extinguisher every 25 square meters.

What to pay attention to when equipped with a fire extinguisher:

1. The scope of application of fire extinguishers. When the fire extinguisher is configured, the type of fire extinguisher is selected according to the field, and the fire situation is different for different types.

For example, Class A fires, that is, fires caused by materials such as hay and wood, can be equipped with water-type fire extinguishers and foam fire extinguishers. For example, to extinguish Class B fires, that is, fires caused by gasoline, kerosene, etc., foam, dry powder and carbon dioxide fire extinguishers can be used.

If you want to fight Class C fires, such as gas, natural gas, etc., dry powder and halide fire extinguishers can be selected. If you want to extinguish Class D fires, that is, metal fires, you can choose a dry powder fire extinguisher. For live fires, dry powder fire extinguishers can be used.

2. The effectiveness of fire extinguishers in extinguishing fires. When configuring the fire extinguisher, it is necessary to pay attention to the degree of fire extinguishing of different fire extinguishers. For example, the amount of carbon dioxide and foam fire extinguishing agent is large, and the fire extinguishing time is long; The amount of dry powder fire extinguishing agent is small, and the fire extinguishing time is short; The dosage of alkyl halide extinguishing agent is moderate, and the extinguishing time is longer than that of dry powder.

3. The ambient temperature of the place. When configuring the fire extinguisher, pay attention to the temperature of the site. If the ambient temperature is too low, the spray performance of the fire extinguisher will be reduced, which will affect the fire extinguishing efficiency.

If the ambient temperature is too high, increase the internal pressure of the fire extinguisher, and even have the risk of injuring the stupid person. Select the temperature range that meets the fire extinguisher.

Fire extinguishers are very common in life, especially in public places, there will be at least two or more on each floor, so that they can be extinguished as quickly as possible in the event of a fire, but the equipment of extinguishing the fire is required, and all areas must be designed in strict accordance with the equipment requirements. So, what are the requirements for fire extinguishers? What factors need to be considered when choosing a fire extinguisher?

Let's take a brief look at it together. 1. What are the requirements for fire extinguishers, and at least 2 or more fire extinguishers are equipped in a unit. The number of fire extinguishers in a unit shall not exceed 5.

For every 100 square meters of the total floor area of a single-storey residential building, one Zhaoye fire extinguisher with a capacity of 1a must be equipped. Different types of fire extinguishers used in a unit should be compatible with the extinguishing agents. The fire extinguisher should be matched according to the type of fire house in the place of use.

2. What factors need to be considered when choosing a fire extinguisher 1. Determine the fire in the place where the fire extinguisher is equipped, and then decide which type of fire extinguisher to use. 2. Determine the danger level of the place equipped with fire extinguishers, and then design the spacing and number of fire extinguishers according to the actual situation, which is the basic factor in the design of fire extinguishers, and must be determined in strict accordance with the "Design Code for Building Fire Extinguisher Configuration". 3. Configure fire extinguishers in the places where important materials are kept, and take into account the degree of fouling after fire extinguishing.

4. The fire extinguisher has high requirements for the ambient temperature of the configuration position, if the ambient temperature is too low, it will affect its fire extinguishing performance, on the contrary, if the ambient temperature is high, it may lead to an increase in the internal pressure of the fire extinguisher, and there is a hidden danger. Summary: The above requirements for fire extinguishers and the factors that need to be considered when choosing a fire extinguisher are introduced here, I hope it will be helpful to you.
