What is explosion-proof cabinet and the role of explosion-proof cabinet

Currently in many factories in the production process, will be used in chemical liquids, such as water, wipe machine water, washboard water, ethanol and so on. Such chemical liquids are flammable or combustible properties, that is to say, these chemicals have a very low ignition point, up to a certain temperature is likely to spontaneous combustion. Then the storage of these chemicals is particularly critical, storage is not reasonable or management is not standardized, it is easy to leak, once the leak may lead to fire.

First of all, what is an explosion-proof cabinet?

Explosion-proof cabinet is called Fire Safety Cabinet, also known as it chemical safety cabinets, fire cabinets, chemical explosion-proof cabinets, we call it different, explosion-proof cabinets have four colors, respectively: yellow, red, blue, white, each color of the stored chemicals are not the same.

Second, what exactly is the role of explosion-proof cabinet?

1. The use of explosion-proof cabinets to store hazardous chemicals can effectively prevent the spillage of chemicals to prevent fire accidents;

2. the effective management of a variety of hazardous materials, different colors of safety cabinets have different functions, can be stored in different chemicals, stored in separate categories, at a glance, easy to manage;

3. Safe use of explosion-proof cabinets can not only protect the working environment safety and health, but also to protect the lives of employees of enterprises, property safety.

4. Exhaust: explosion-proof safety cabinets are equipped with a built-in flame arrester (with plug) containing a double exhaust port, usually located on both sides of the cabinet, one side high and one side low. According to the relevant safety regulations, if not exhaust, the exhaust port should be sealed with a plug; if the cabinet needs to exhaust for any reason, it should be set up in accordance with the relevant safety standards, and must not affect the performance of explosion-proof safety cabinets.

5. Grounding: Steel safety cabinets come with a built-in grounding plate, generally located on the right side of the bottom. For the safe storage of flammable materials, it is necessary to ground the cabinet as far as possible for safety reasons. If the distribution and collection processes are carried out in the safety cabinet, such as pumping from the drum or filling the drum with waste liquid through a funnel, it is essential that the safety cabinet should be grounded and the correct joining technique should be used directly from the container.

Third, in the use of explosion-proof cabinets also need to pay attention to the following safety matters

1. The ground on which the explosion-proof safety cabinets should be placed level.

2. If there are a number of explosion-proof safety cabinets placed together, the spacing between each cabinet should not be less than 15 cm. 3. Explosion-proof safety cabinets placed in the place should be away from fire or other heat dissipation of instruments and equipment, should also be away from the splash of chemical liquids or slag.

4. Cabinet on the left side of the outer wall of the lower corner of a static conductive ground terminal, to be placed in the cabinet properly, should be connected to the static grounding wire, in order to lead away from the cabinet in time to the accumulation of static electricity.

5. The items placed on the cabinet laminates should not exceed the load-bearing limit of the laminates. Laminates if there are more than one layer, when placing items, should be larger or heavier items placed on the bottom of the laminate, will be smaller or lighter items placed on the top of the laminate.

6. If the explosion-proof safety cabinet is placed in a confined space, or the place where the cabinet is placed on the volatilization of flammable liquids have strict restrictions, then the cabinet should be connected to the vent on the exhaust system to eliminate the volatilization of flammable liquids accumulated in the cabinet.

7. At night or in the dark under the conditions of insufficient light, if you need to place items in the cabinet or other operations, you should turn on the surrounding lamps, or carry explosion-proof flashlights for operation.

8. It is strictly prohibited to light candles, alcohol lamps or the use of lighters near the cabinet and any other operating behavior that may cause combustion and explosion.

9. It is strictly prohibited to smoke in the place where the cabinet is stored, throw fireworks or throw other objects that are burning.

10. After the door is opened, pay attention to close the lock, it is strictly prohibited to cabinet door open for a long time, in order to avoid the source of ignition into the cabinet.

11. Usually pay attention to protect any locks installed on the cabinet, to avoid the locks being hit or other damage.

12. usually pay attention to protect the cabinet, prevent collision, scraping or corrosive chemical liquids on the cabinet splash, so as to avoid bruising and damage to the cabinet or damage to the coating on the cabinet.

13. It is strictly prohibited to put strong corrosive chemicals in the explosion-proof safety cabinet. Strongly corrosive chemicals shall not be placed in the same cabinet with flammable and combustible chemicals, you should purchase a special cabinet of highly corrosive chemicals classified storage.

14. Cabinet body installed on any locking placement, are required to arrange for a person responsible for the management, non-management personnel are strictly prohibited to open indiscriminately.

15. It is recommended that the key management personnel in advance with a set of keys, in case of key damage or accidental loss of use. Explosion-proof cabinet is not safe, with the right “safety cabinet”, with the wrong is “life-saving cabinet”, the enterprises must attach great importance to strengthening the investigation of potential safety hazards, good management of explosion-proof cabinet!
