Gas-purifying Fireproof Chemical Safety Storage Cabinet

This product features functions such as explosion - proof, anti - theft, fire - retardant, corrosion - resistant, and ventilation.

* The entire cabinet body is crafted from 1.2 - mm cold - rolled steel sheets, while the cabinet base is made of 2.0 - mm cold - rolled steel sheets. Both the inner and outer surfaces undergo pickling, phosphating, epoxy resin powder spraying, and heat - curing treatments.

* The cabinet liner (including the upper, lower, left, and right inner lining boards) is entirely made of porcelain - white pp (polypropylene resin) boards. There is an adjustable air inlet on the right side of the cabinet, equipped with a stainless - steel adjustable air damper. At the bottom inside the cabinet, there is a cavity (leakage trough) that can hold yellow sand with a thickness of no less than 120 mm, designed for burying flammable items such as sodium metal and yellow phosphorus (white phosphorus). The baffle should be integrated with the cabinet body. Four φ50 - mm movable casters are installed at the bottom of the cabinet, facilitating its movement and the positioning of the cabinet for storing flammable items.

* Inside the cabinet, there are three one - piece pp polypropylene resin movable shelves in a three - layer stepped design, and the shelves are equipped with 10 - mm ventilation holes.

* There is a φ150 - mm air outlet in the middle of the cabinet top, with an AC220V, 50Hz, 0.18A axial - flow fan built into it. The maximum air volume exceeds 300 m³/h, the rotation speed is 2550 r/min, and the operating temperature ranges from - 10°C to + 70°C. The control switch is located at the upper - right corner of the cabinet top. Before turning on the fan, the air inlet in the middle below the cabinet door should be pushed to the open state.

* Fire - proof material: The cabinet is filled with ceramic fiber, a fire - proof material with heat - insulation properties.

* Hinge: A piano - type hinge is used to ensure that the door can open up to 180 degrees. A fire - expansion seal is installed between the cabinet door and the cabinet body.

1. An air inlet and an adjustable air damper are provided at the bottom of the cabinet. The adjustable air damper is flexible and can control the air volume.

2. The cabinet should be equipped with ventilation openings, and the maximum wind speed at the ventilation openings should be no less than 0.5 m/s.

3. It comes with a micro - computer time - control switch, which can automatically turn the fan on and off according to the time set by the user. The power - switch indicator shows whether the fan is working properly and can be controlled either automatically or manually.

4. The diameter of the ventilation duct is preferably φ160 mm. The ventilation duct should be heat - resistant, fire - retardant, and corrosion - resistant.

* Ventilation control device:

* Special safety requirements: The key of the mechanical lock and the password of the electronic combination lock should be kept separately by two people, and both of them must be present when opening the cabinet.

Time - controlled and Temperature - Humidity - controlled Integrated Alarm Device

A temperature - humidity controller should be installed on the top of the cabinet to monitor the relative temperature and humidity inside the cabinet in real - time. The set values and measured values are displayed numerically. If the temperature and humidity inside the cabinet exceed the set measured values, an alarm will be given immediately. Also, the device can automatically turn on and off the fan according to the time set by the user. The power switch indicator shows whether the fan is working properly. It can be controlled automatically or manually. The power supply is AC220V±10％, 50HZ. The temperature starting control range is 0 - 99.9℃ (set by the user), and the humidity starting control range is 0 - 99.9％RH (set by the user).

Instructions for Accessing Hazardous Chemicals

Chemicals in the storage cabinet should not be stored for an extended period.

The storage cabinet should be used exclusively for its intended purpose and should not store non - hazardous chemicals.

Storage containers should be in good condition. If there is any damage, immediate measures should be taken, such as transferring the chemicals to another container or using them up promptly.

For chemicals that emit corrosive gases, the bottles should be tightly sealed and placed on the upper shelves of the cabinet for proper ventilation.

Chemicals should be stored in layers, compartments, or separate cabinets according to their chemical properties, such as oxidizers, reducers, strong acids, and strong alkalis.

Flammable items such as sodium metal and yellow phosphorus (white phosphorus) should be stored in the cavity filled with at least 120 mm of yellow sand at the bottom inside the cabinet.

Hazardous chemicals with incompatible chemical properties or fire - prevention and fire - fighting methods must be stored separately.

Inorganic oxidizers and strong acids (such as sulfuric acid and nitric acid) in the drug storage cabinet are strictly prohibited from being stored together.

The storage cabinet must implement a dual - custody system, including dual - handling for receiving and issuing, dual - use, and dual - locking. Actual access situations should be recorded and registered with real names.

Hazardous chemicals that have expired, deteriorated, and need to be discarded due to long - term storage, as well as the waste liquid in the drip tray at the bottom of the cabinet, must be properly handled by a dedicated person in accordance with the regulations for hazardous waste disposal. They should not be directly poured into the sewer or ordinary trash cans.

Parameter (Specification)

Feature And Application

Equipped with an adjustable air inlet and a built - in axial - flow fan, it can achieve efficient ventilation. The maximum air volume exceeds 300 cubic meters per hour, which is extremely suitable for places with strict requirements for air circulation, such as laboratories and chemical handling areas. In addition, the device has a built - in microcomputer timing control function, which can automatically or manually manage the working state of the fan. It is very suitable for places that require regular monitoring and automated management, such as production workshops and laboratories.
