Yellow Flammable Safety Cabinet for School Labs | 4-90 Gallon Chemical Storage with Leak-proof Sump

1. Product Overview: The Guardian of Laboratory Safety

Safety is the top priority in any educational or industrial environment. Luoyang Hengna Office Furniture Co., Ltd. presents the Yellow Flammable Safety Cabinet, a premium storage solution engineered specifically for the safe containment of Class 3 flammable liquids (such as alcohol, gasoline, and ether) and other hazardous chemicals.

Designed to meet strict international standards (OSHA 29 CFR 1910.106 and NFPA Code 30), this cabinet is an essential line of defense for school learning laboratories, university research centers, and industrial workshops. By isolating dangerous chemicals from potential ignition sources, our cabinets provide critical evacuation time in the event of a fire, protecting both students and property.

As a leading manufacturer based in Luoyang, Hengna offers factory-direct quality with customizable options for global wholesale buyers.

2.Flammable Safety Cabinet Key Features & Benefits

Maximum Fire Protection

The cabinet features a double-wall steel structure constructed from sturdy 1.2 mm (18-gauge) cold-rolled steel plates. Between the two steel layers is a 38mm insulating air space, which acts as a thermal barrier. In the event of an external fire, this air gap significantly slows down the heat transfer to the chemicals inside, preventing explosions and buying valuable time for emergency response.

50 mm Leak-Proof Sump

Accidental spills are common in student laboratories. To prevent dangerous chemical spread, the bottom of the cabinet is equipped with a 5 cm (50 mm) high leak-proof liquid tank (sump).

• Function: If a bottle breaks or leaks, the chemical is contained strictly within the cabinet.
• Benefit: Keeps the classroom floor clean and safe, complying with EPA spill containment regulations.

Dual-Lock Security System

School laboratories require strict access control to prevent unauthorized handling of dangerous chemicals by students. Our cabinet features a double-locking system:

1. Flush Paddle Handle: Easy to operate with a built-in key lock.
2. Additional Padlock Hasp: Allows for a secondary padlock (optional). This “Double-Person, Double-Lock” management capability ensures that hazardous materials are only accessible when a teacher or lab supervisor is present.

Durable & Chemical Resistant Design

• Galvanized Laminate Shelves: The adjustable shelves are made of galvanized steel, offering superior corrosion resistance against leaks. They are designed to direct spills to the back and bottom of the leak-proof sump.
• Uninterrupted Piano Hinge: Unlike standard butt hinges, the full-length piano hinge runs from the top to the bottom of the door. This ensures the door closes smoothly every time and creates a better seal against fire.
• Lead-Free Powder Coating: The high-visibility yellow finish is not just for warning; it is a durable, chemical-resistant epoxy powder coating that withstands harsh lab environments.

Ventilation & Grounding

• Dual Vents: Equipped with dual vents with flame arresters (on both sides of the cabinet) to effectively reduce the concentration of volatile gases inside.
• Static Grounding: A built-in grounding connector allows for anti-static grounding, preventing sparks caused by static electricity build-up.

6. Proper Usage & Maintenance Tips

To maximize safety and the lifespan of your cabinet, please follow these guidelines:

1. Placement: Place the cabinet on a level surface indoors, away from direct exits, to ensure evacuation routes remain clear.
2. Grounding: Always connect the static grounding wire (located on the side) to an earth ground to prevent static sparks.
3. Loading: Do not overload the shelves. Ensure the containers are sealed tightly. Place heavy containers on the bottom shelf.
4. Spill Management: If a spill occurs, the 5 cm leak-proof tank will catch it. Use absorbents to clean the sump immediately.
5. Ventilation: If storing highly volatile or odorous chemicals, connect the side vents to an external ventilation system.
