Are Filing Cabinets Fireproof?

Traditional filing cabinets are not fireproof. Since most are made from steel, they are terrible insulators. Luckily, there are fire-resistant file cabinet alternatives. These options have a layer of inflammable material between the walls, which help insulate and slow down internal rising temperatures.

Ultimately, the cabinet will get too hot and lead to combustion. Fireproof cabinets stall as you find ways to put out the fire.

If the filing cabinet is for storing important documents, you will have to go the extra mile to ensure you protect them from fires. Before purchasing a file cabinet, it is vital to check the heat levels it can resist. On top of that, the amount of time it takes before the contents burn completely matters. Another feature is individual drawer protection. Even if one is left open, the others will remain safe.

If you need a safe place to store valuable paperwork such as wills, passports, marriage certificates, a small amount of cash, and valuables from fire damage, then a fireproof file cabinet will work great.

Are filing cabinets waterproof?

Not all file cabinets have water-resistant seals. In a fire, the heat and smoke will trigger the sprinklers (if any) to switch on automatically. It is one thing to protect your files from fire, only for them to get destroyed by water. Waterproofing is necessary on top of fireproofing to keep your important documents safe and dry.

It is expected that some moisture might seep in. However, the best filing cabinets keep most of the water out and prevent adverse damage. Even if the cabinet is submerged in water, the cabinet should remain water resistant. Some brands can withstand being submerged in up to eight inches of water for 24 hours. Others can only be resistant to sprinkler and hose damage.  

The waterproof feature does not work as efficiently with non-metal file cabinets. However, if you prefer file cabinets made from other materials, go for those made from white oak. White oak is a durable hardwood that is impervious to water. It does not absorb water, is resistant to moisture, and does not warp. These features would make it perfect for a waterproof file cabinet.

Can metal and steel cabinets burn?

Metal and steel cabinets cannot burn. However, they are perfect conductors of heat and will act like incinerators in case of a fire. The files inside will ultimately ignite and burn completely.

Unless you get a fireproof file cabinet, traditional steel and metal filing cabinets are a shell. They have no additional material to help resist the effects of a fire. Although the cabinet itself cannot burn, your documents will.

Most galvanized steel file cabinets are made of 18-gauge steel. This material makes them durable but does nothing for protection against fires. In reality, no file cabinets are fireproof. They are fire-rated. This means that they can withstand fire damage for a certain period. After that, your files will catch fire and burn to ashes if nothing is done to salvage the situation.

Temperatures on the outside of a steel cabinet determine those inside the file cabinet. If it is hot outside, it will be just as hot inside.

What are fireproof file cabinets made of?

Fireproof cabinets are made with inflammable material between the walls. Some brands fill these special encapsulated spaces with vermiculite, which is a lightweight clay mineral. This material is also highly water absorbent. In case of a fire, the vermiculite melts into water. It then turns into steam, absorbing the heat and keeping the files in the cabinet cool.

Companies reinforce the insulating materials with strong metals and strict welding techniques. Most fireproof cabinets are UL (Underwriters Laboratories) classified. That means they are certified to withstand heat up to a specific degree for a certain period. UL certification happens in classes.

The UL Class 350 1-hour and UL Class 350 2-hour can withstand external temperatures 1700˚F and up to 350˚F internally for at least one and two hours respectively. These file cabinet classes are perfect for storing paper documents and are mostly made of stainless steel, cast iron or aluminum. Cabinets made from oak have a burning point of about 572˚F.     

The best fireproof cabinets in the market can withstand up to two hours of scorching temperatures. That period is adequate time to try to put out the fire. The downside is that these file cabinets are heavier than the standard steel cabinet. They are more challenging to move around or transport because of the material responsible for insulation.
