Portable dry powder fire extinguisher pay attention to the problem
1. When using a fire extinguisher to extinguish the fire, avoid impacting the liquid surface and splashing with fire prevention species.
2. Once the fire extinguisher is opened and used, it cannot be stored and reused. It must be refilled by the professional fire-fighting equipment business department before it can be stored and used.
3, patrol inspection should be strengthened to check whether the pressure meets the requirements, whether the nozzle is damaged, whether there is obvious corrosion in the appearance, etc.
How to distinguish the authenticity of a portable dry powder fire extinguisher
1. Pay attention to the trademark: it is the trademark on the barrel of the portable dry powder fire extinguisher. The trademark should be correct, without lack of edges, no obvious wrinkles, bubbles and other defects. The name brand is not incomplete and clear. The type of fire extinguishing agent and driving gas, Filling pressure, total quality, fire extinguishing level, operation method, precautions, manufacturer’s name and production date are complete; the content is not all unqualified products; there must be a warning text "Once the fire extinguisher is turned on, do not reuse or refill" Description. If there is no warning text, it is unqualified.
The appearance signs of fake and inferior fire protection products are often vague and rough, incomplete and not durable. For example, the trademark casting on the tank of inferior fire extinguisher is vague and generally has no production date; fake and inferior fire doors do not have due signs and have rough surfaces.
2. Pay attention to the barrel: the outer surface of the fire extinguisher barrel should have uniform color, no cracks, bubbles, no obvious scratches, bumps, knocks, corrosion, leakage (especially the bottom of the barrel and the weld) and other defects, otherwise It is a substandard product. In addition, the bottom ring or neck ring of a qualified fire extinguisher should have the water pressure test pressure value of the fire extinguisher and the steel stamp of the year of manufacture. The positions of the steel seals of unqualified products are different, and the steel seal numbers are also very different. Whether the number on the fire extinguisher bottle is consistent with the number on the inspection certificate issued by the national inspection department provided by the fire extinguisher seller.
3. Pay attention to the pressure: the fire extinguisher whose pressure indicator does not reach the green area is a substandard product. The type of pressure indicator should be consistent with the type of the fire extinguisher. The fire extinguisher with a filling volume greater than 3kg should be equipped with a spray hose; the fire extinguisher should be equipped with a safety pin, and the lead seal (plastic tape, wire seal) of the safety pin should be intact, Otherwise, it is a substandard product.
4. Pay attention to the "ID card" information of the fire extinguisher: When buying a regular fire extinguisher, you will usually find two stickers with an area of about 4 square centimeters on the fire extinguisher, one of which is red and black coated, and the other is black and white paper Yes, the former is directly attached to the bottle body, while the latter is hung on the bottle mouth or other parts. These two are the "identity cards" of the fire extinguisher. The red and black ones are the originals of the "identity cards", which are carried by the fire extinguisher for life; the black and white paper copies are the copies of the "identity cards". And this "ID card" has special anti-counterfeiting properties. Only the plastic film on the surface can be torn off, but the "ID card" stuck on the fire extinguisher itself cannot be removed, so it cannot be transferred to another fire extinguisher.
On the one hand, you can log on to the China Fire Products Information Network or the website of the Fire Product Evaluation Center of the Ministry of Public Security and enter the 14-digit clear code on the'ID card' for inquiries. On the other hand, firefighters only need to use an electronic pen to touch the'ID card'. After you connect the pen to the computer, you can see the product number and other information and check the authenticity.
