Although many freezers are made with heat-resistant materials, it doesn’t make them fireproof. The temperature of a house fire is higher than that of a freezer, so it may not survive. Experts disagree, however, about the fireproofed of freezer. It all depends on the model.

Metal backings are better
Fireproofing freezers can help prevent house fires. Metal backings can offer greater protection against fire than plastic fridges. Regular maintenance can also increase the lifespan of your fridge. Plan your escape route in the event of a fire.
Flammable plastic backings
The use of flammable plastic backings in freezers is dangerous for the environment. Although they may not be flame-resistant, these backings can quickly spread flames. This can have disastrous consequences for a homeowner. Luckily, there are some steps that people can take to avoid purchasing a freezer with flammable plastic backing.
Faulty wires
Faulty wires in freezers can be hard to diagnose and fix. First, you need to determine the type of circuit interrupter that your freezer is using. Typically, it will trip when it detects a power overload or when electricity leaves the circuit. However, intermittent tripping can also be caused by faulty or overloaded circuit breakers. Sometimes the problem is as simple as a bad connection between two wires.
Gas pressure
A freezer that is leaking gas may be caused by a clogged defrost drain. A puncture can also cause a gas leak in the freezer’s line. Disconnect the freezer from the mains immediately and contact the manufacturer. Modern freezers use HCFC or HFC gases that are less harmful for the ozone layer.
Insulated wall panels
In addition to fire-proofing the freezer, insulated wall panels can also help to reduce the fire risk of an office building. These panels have a UL 94V-1 fire rating and are designed to reduce heat exchange between the interior of the building and the exterior. Fire-rated insulation panels are generally better than combustible insulation because they reduce the fire load and spread fire slower. Sprinklers are also recommended to protect stored items from fire.
Faulty parts
Faulty parts in freezers are fire hazards that can spread quickly. A fire that is caused by one of these parts can cause a fire that ignites a larger fire, which could lead to carbon dioxide suffocation. Heavy burns can also be fatal. Look for fire-resistant plastics to avoid heavy burns.
