Important information about refractory items

In order to turn a normal cash box and a wooden box into a fireproof box, you should familiarize yourself with the term fireproof:

• Non-flammable and fireproof have different meanings. A tin can won't burn, but it can't keep the contents from charring. A box made of oak, on the other hand, burns, but can certainly protect the contents from fire damage because the energy of the fire is contained when the wood is burned.
• No object is absolutely fire-proof. Depending on the temperature and duration of exposure, a fireproof box will also deform or no longer be able to protect the contents from heat. Many boxes that are offered in stores guarantee that the documents are only protected from damage for 30 minutes.

You can make many materials fireproof by using coatings. You can even coat paper so that it doesn't burn and go out by itself.

Coatings for fireproof boxes

• Get intumescent fire protection paint. Such colors exist for wood and metals. These colors emit so-called inert gases, mostly carbon dioxide or nitrogen, which are suitable for keeping atmospheric oxygen away from the source of the fire. At the same time, carbon foam is created that does not burn and protects the material underneath from the heat of the fire.

Construction of a refractory box

1. Build yourself a tightly fitting wooden box into which you can easily insert a cash box. The cassette should lie loosely in the box, i.e. not be pressed into it.
