Modern School Lab Safety Storage Fire Proof Explosion-Proof Metal Cabinet for Gas Cylinder

Gas cylinder storage cabinets are used for storage of gas cylinders in laboratory, workshop and etc. Its function is to protect the gas cylinder stored within from exterior fire, and contain the fire within the cabinet from the surroundings if any. Special purpose alarm device and automatic exhaust system can be installed according to the storage requirement, further enhancing safety to the environment.

Primary Purposes & Benefits

1. Containment of Leaks: The most critical function. If a cylinder valve or regulator leaks, the cabinet contains the gas, preventing it from spreading into the workspace.

2. Hazard Segregation: Isolates incompatible gases (e.g., flammables from oxidizers) from each other and from ignition sources.

3. Physical Protection: Protects cylinders from being knocked over, damaged, or tampered with.

4. Fire Protection: Provides a defined fire-resistant barrier (typically 30-minute to 2-hour fire rating) to protect cylinders from external fire and delay their involvement.

5. Ventilation: Directs hazardous gases safely to the atmosphere via an exhaust system, preventing the buildup of toxic, flammable, or asphyxiating gases.

6. Security: Lockable doors prevent unauthorized access to hazardous materials.

Common Types & Classifications

Cabinets are categorized by the type of gas they are designed to store:

1. Flammable Gas Cabinets:

· Color: Typically Yellow (common standard, though not universal).

· Features: Double-walled construction, 18-gauge steel, 1.5" air gap for insulation. Includes flame arrestors in vent ports and baffled vents. Must be grounded for static electricity.

· Examples: For acetylene, hydrogen, methane, propane.

2. Corrosive Gas Cabinets:

· Color: Typically Blue or Grey.

· Features: Constructed from corrosion-resistant materials (e.g., polypropylene, PVC-coated steel, stainless steel). Often include built-in secondary containment trays or sumps to capture leaks. Exhaust is mandatory and critical.

· Examples: For chlorine, ammonia, hydrogen chloride, sulfur dioxide.

3. Toxic Gas Cabinets:

· Color: Varies (often grey or custom).

· Features: Highest level of containment and monitoring. Usually include continuous gas monitoring sensors (interlocked with alarms and ventilation), redundant ventilation systems, and automatic cylinder valve shut-offs. May have pass-through boxes for regulator maintenance.

· Examples: For arsine, phosphine, chlorine, carbon monoxide.

4. Oxidizer Gas Cabinets:

· Color: Typically Green.

· Features: Designed to separate oxidizers from flammable materials. Constructed similarly to flammable cabinets but clearly labeled for oxidizers.

· Examples: For oxygen, nitrous oxide, chlorine.

5. General Purpose / Cylinder Storage Cabinets:

· For non-hazardous or inert gases (e.g., nitrogen, argon, helium). Focus is on stability and organization rather than containment or fire rating. May not require forced ventilation.

Gas cylinder cabinet from Jinhua Rio Tinto Steel Cabinet Co., Ltd. Key Design Features & Components as below:

· Construction Material: Heavy duty steel

· Doors: Self-closing, close-fitting doors with locks. Some have viewing windows.

· Leak Containment: Sill or spill containment sump to hold a volume of liquid from a leaking cylinder.

· Cylinder Restraints: Internal chains, straps, or bars to securely anchor cylinders upright.

· Shelving: Adjustable, perforated shelves for smaller cylinders or related equipment.

· Labeling: Prominent hazard warning signs (e.g., "Flammable Gas," "Corrosive," "Oxidizer").

Best Practices for Use

1. Segregation: Never store incompatible gases in the same cabinet (e.g., flammables and oxidizers must be separated).

2. Ventilation: Always connect and use the exhaust system for hazardous gases unless specifically designed as non-ventilated for inert gases. Verify airflow regularly.

3. Grounding: Ground flammable and corrosive gas cabinets to prevent static discharge.

4. Capacity: Do not exceed the maximum number of cylinders recommended by the manufacturer or NFPA limits.

5. Accessibility: Keep aisles and access to cabinets clear. Doors must be able to open fully.

6. Inspection: Regularly inspect cylinders, regulators, cabinets, and restraints for damage.

7. Training: Ensure all personnel are trained on the hazards of the gases and the proper use of the cabinet system.
