1. Brief introduction of explosion-proof cabinet

Explosion-proof cabinets, also known as safety cabinets, fire-proof cabinets, explosion-proof safety cabinets, dangerous goods storage rooms, fire-proof cabinets, and flammable and explosive liquid storage cabinets, are fire-fighting and security products that can store hazardous chemicals by classification.

The explosion-proof cabinet is a special industrial safety cabinet for storing flammable and explosive materials, flammable and explosive materials, and weakly corrosive materials. It is also a special fire-proof and explosion-proof storage tank designed according to industrial production safety.

At the same time, it can prevent the liquid overflow of dangerous chemicals, prevent fire, fire and explosion accidents, and play the role of fire prevention and explosion protection.

High-quality explosion-proof cabinets should obtain relevant certifications such as CE certification, OSHABIA standards and NFPA standards, explosion-proof test analysis reports, and fire resistance test analysis reports.

2. Characteristics of explosion-proof cabinets

The main results are as follows:

1) The explosion-proof cabinet adopts a double-layer steel structure, and the inside and outside are treated by pickling, phosphating, and epoxy resin electrostatic spraying. Products, to achieve a complete fire effect.

Explosion-proof cabinets are not easy to deform, not easy to absorb moisture, anti-rust, anti-corrosion, safe and stable, and become an indispensable safety product in modern industry.

2) In the event of a fire, the special material inside the cabinet can block the fire source and better prevent the development and spread of the fire.

(3) There is a special ground wire in the cabinet, which can output all the static electricity generated in the cabinet, so as to better prevent fire caused by static electricity.

3. Small size, better storage of dangerous goods, can be placed flexibly, conveniently and comfortably.

Explosion-proof cabinet safety management

1) Exhaust

Explosion-proof safety cabinets are equipped with double exhaust ports and built-in fire extinguishers (with plugs). They are usually located on both sides of the cabinet, with one side high and one side low. According to the relevant safety regulations, if there is no exhaust, the exhaust port should be sealed with a plug; if the safety cabinet needs to be exhausted for any reason, it should be exhausted according to the phase. Turning off the safety standard setting must not affect the performance of the explosion-proof safety cabinet.

2) grounding

Fire safety cabinets should adopt anti-static design. When purchasing chemical fire and explosion cabinets, they should be equipped with anti-static conductors. The function of this anti-static wire is to eliminate and guide static electricity and prevent fires caused by static sparks.

The grounding of the explosion-proof cabinet is divided into internal grounding and external grounding.

External grounding: Install grounding screws and grounding wires at specially arranged contact points in the explosion-proof cabinet, and the other end of the grounding wire is connected to the grounding bus bar or grounding rod.

Internal Grounding: When liquids are dispensed and collected in explosion proof cabinets, it is important to pump liquid from drums or funnel waste into drums while ensuring electrical conductivity between metals. For painted products, you can scrape off the paint to expose the metal for attachment. Some grounding clips are designed with a cone tip piercing the paint. Shake the ground clip until the tip of the ground clip pierces the coating in contact with the metal part.

4. Matters needing attention in the use of explosion-proof cabinets

The ground where the explosion-proof safety cabinet is placed should be flat.

If multiple explosion-proof safety cabinets are put together, the distance between each cabinet should not be less than 15 cm.

Explosion-proof safety cabinets should be kept away from fire sources or other heating and heat dissipation instruments and equipment, as well as splashed chemical liquids or slag.

There is an electrostatic conductive terminal in the lower left corner of the cabinet, which should be connected to the static grounding wire when properly placed to guide the accumulation of static electricity in the cabinet in time.

Items placed on cabinet laminates must not exceed the load-bearing limits of the laminate. If the laminate has multiple layers, larger or heavier items should be placed on the lower laminate, and smaller or lighter items should be placed on the upper laminate.

If the explosion-proof safety cabinet is placed in a closed narrow space, or where there are strict restrictions on the volatilization of flammable liquids, the ventilation system should be connected to the vents of the cabinet to eliminate the flammable liquids accumulated in the cabinet due to volatilization. flammable liquid.

If there is insufficient lighting at night or at night, if it is necessary to place items or other operations in the cabinet, turn on the surrounding lights or carry an explosion-proof flashlight for operation.

It is strictly forbidden to light candles, alcohol lamps or lighters near the cabinet to avoid burning and explosion.

Smoking, littering of fireworks, or disposal of other burning items are strictly prohibited where the cabinets are stored.

After opening the door, pay attention to the door lock. It is strictly forbidden to open the cabinet door for a long time to prevent the fire source from entering the cabinet.

Usually care is taken to protect any door locks installed on cabinets to avoid being hit or otherwise damaged.

Usually, care should be taken to protect the cabinet and prevent collision, scratching or corrosive chemical liquid from splashing on the cabinet, so as not to damage the cabinet or damage the coating on the cabinet.

It is strictly forbidden to place strong corrosive chemicals in explosion-proof safety cabinets. Do not put strong corrosive chemicals and flammable chemicals in the same cabinet. Purchase special strong corrosive chemical cabinets for classified storage.

Any locking device installed on the cabinet must be managed by special personnel, and it is strictly forbidden for non-management personnel to open it at will.

It is recommended that the administrator of this key pre-provides an extra set of keys for use in case of damage or accidental loss of keys.
