Standard and Deluxe Storage Cabinets
Standard and deluxe cabinets share most features and differ mainly in the steel and hardware. Both grades lock at three points with one turn of the handle, and both sit on a raised base that keeps stored items clear of floor-cleaning liquids. Shelves adjust in 2-inch increments without tools or clips. Deluxe cabinets use heavier steel and knuckle hinges, which matter most on tall cabinets in heavy use.
| Standard | Deluxe | |
|---|---|---|
| Steel | 24-gauge body on a 22-gauge frame | Heavy-gauge body with 16-gauge door frames |
| Hinges | Leaf hinges, 3 per door on the larger sizes | Knuckle hinges, up to 4 per door, to keep tall doors aligned |
| Handles | One chrome handle with a lock | Two brushed chrome handles. One handle locks both doors. |
| Shelves | Up to 200 lb each | Heavy-gauge steel, the same as the rest of the cabinet |
| Base and ventilation | Raised base | Raised base, leveling feet for uneven floors, and a louvered back panel for air flow |
| Shipment | 5 to 7 days after the order | 5 to 7 days after the order |
Both grades are 36 inches wide, 18 or 24 inches deep, and 30, 42, or 72 inches tall, in storage, wardrobe, or combination configurations. Both are available assembled or ready to assemble, in 5 standard finishes. Tennsco cabinet catalog (PDF)
Fire Code Limits on Flammable Liquids and Gas
Flammable liquids and gas cylinders fall under fire code limits that do not apply to general storage. Chapter 50 of the fire code covers flammable and combustible liquids, compressed gases, aerosols, and corrosives, and it limits how much of each material a building can hold. That limit is the maximum allowable quantity (MAQ). Above the MAQ, the building requires additional protection.
Approved flammable cabinets allow more flammable and combustible liquid to be stored in certain areas. Quantities near the limit should be identified when the space is permitted.
Aerosols, compressed gases, corrosive materials, and flammable liquids are high-hazard materials under Chapter 50 of the fire code. A warehouse can hold only a limited quantity of each. Above that limit, the building requires features such as secondary containment, roll-up doors, or foam systems, and compliance becomes much more expensive.
Flammable Storage Cabinets
In a fire, a flammable cabinet protects its contents for a period of time, which gives occupants more time to evacuate and the fire department more time to control the fire before it reaches the contents. The cabinets we supply are FM Approved to standard 6050 for ignitable liquids. They meet NFPA 30, the National Fire Protection Association code for flammable and combustible liquids, and the requirements of the Occupational Safety and Health Administration (OSHA). The fire code classifies liquids by how easily they ignite, from Class I (most easily) to Class III (least easily), and limits the quantity of each class in one cabinet.
Class I and II Liquids
60gal
Maximum quantity per cabinet
A 90-gallon cabinet is still limited to 60 gallons of Class I or II liquid.
Class III Liquids
120gal
Maximum quantity per cabinet
The largest flammable cabinets we supply are sized for this limit.
Double Wall
1½in
Insulating air space between two 18-gauge walls
The doors are also double-walled, with 14-gauge steel outside and 18-gauge steel inside. A 2-inch sill at the bottom retains leaks inside the cabinet.
Gas Cylinder Cabinets
Gas cylinder cabinets secure compressed gas and propane cylinders against theft and unauthorized access. The sides are heavy wire mesh. Leaking gas vents through the mesh instead of accumulating, and the cylinders can be inspected without opening the door. The cabinets are available in powder-coated steel or weather-resistant aluminum, meet OSHA 1910.110, and ship fully assembled in 1 to 2 days. Cabinet size depends on the type and number of cylinders.
| Cylinders | Orientation | Capacity per cabinet |
|---|---|---|
| Propane for floor scrubbers | Upright | 2 or 4 cylinders |
| Forklift propane, 20 to 48 lb | Horizontal, on tube rails | 4, 8, 12, or 16 cylinders |
| Welding gas, up to 200 lb | Upright, secured with chains | 5 to 10, or 10 to 20 cylinders |
| Forklift and welding cylinders combined | Both orientations in one cabinet | 8 forklift cylinders plus 5 to 10 welding cylinders |
Sizes and model numbers are listed in the safety and gas cylinder cabinet catalog (PDF).
