1. What is a safety cabinet?

The safety cabinet is a storage cabinet with an anti-static design and fire protection function that provides safe storage, sub-packaging, and classified management for hazardous chemicals.

 

2. Equipment function of fire safety cabinet

Various sizes and types of fire safety cabinets can provide safe storage, sub-packaging and classified management of hazardous chemicals.

Various fire-proof and explosion-proof cabinets of different sizes can provide safe storage of flammable and flammable liquids and chemicals. The small-sized chemical storage cabinet can be placed in the workplace to store combustible, combustible products and organic solvents, saving the trouble of going to and from the dangerous goods storage room. Even in places with small working spaces, small fire safety cabinets can provide safe storage for flammable and flammable liquids and chemicals.

 

3. Color classification of fire safety cabinets

The colors of fire safety cabinets are red, yellow, and blue. The three colors of fire safety cabinets store different types of chemicals. Yellow safety storage cabinet: used to store all kinds of flammable items; red safety storage cabinet: used to store all kinds of combustible items with a flash point above 45°C; blue safety storage cabinet: used to store all kinds of weakly corrosive items or weak acid and weak base.

 

4. Why use chemical fire safety cabinets?

-To prevent fires, the leaking tank prevents accidental outflow of liquid from spilling;

-Protect people's lives, protect property, and the environment;

-Reduce costs and improve work efficiency. Because of its small size, it can be placed in the workplace to store flammable and explosive products, without frequent trips to the dangerous goods storage room, which saves time and effort;

-Effective management of various dangerous goods. The functions of different color safety cabinets are different, and the chemical supplies that can be stored are also different. They are stored in different categories, which is easy to manage at a glance;

-In the process of storing chemicals, use colored labels to identify, sort, and separate various flammable or dangerous liquids. This can also facilitate firefighters to identify hazards in the event of a fire.

 

5. Precautions

-The chemical fire safety cabinet must be installed horizontally. In order to keep the safety cabinet horizontally placed in some uneven positions, the requirements can be achieved by adjusting the leveling feet at the bottom.

-Fire-proof holes and vents with fire-proof and flame-extinguishing devices are located on both sides of the cabinet body to better maintain ventilation and exhaust. This hole is usually ventilated, but in the event of a fire, after the high-temperature fuse is blown, the parts in the hole cover will automatically open, and then the cabinet will be sealed. When special requirements are required, a ventilation system should be added to the safety cabinet.

-The safety cabinet must be grounded.

-Fire safety cabinets should be designed with an anti-static design. When purchasing chemical fire safety cabinets, there will be an anti-static wire inside. The function of this anti-static wire is to eliminate and conduct static electricity and prevent fires caused by static sparks. The grounding of the safety cabinet includes internal grounding and external grounding.

-For external grounding, install the grounding screw and grounding wire at the grounding point specially set in the safety cabinet, and connect the other end of the grounding wire to the grounding bus or grounding rod.

-Internal grounding. When dispensing liquids in a safety cabinet, it is important to ensure the current continuity between metals. For painted products, you need to scrape off the paint to expose the metal part for connection. Some ground clamps are designed with a tapered tip for piercing the paint. Shake the ground clamp until the tip of the ground clamp pierces the paint and contacts the metal part.

-Ensure that the three-point linkage-type self-locking device door lock of the fire cabinet is intact.

-The flammable liquid in the cabinet is always kept sealed.

-Obvious labels should be posted outside the cabinet, preferably reflective or luminous.

-Adopt double lock management.
