Anti-Arson Letterboxes and Mailboxes

What is an anti-arson letterbox and bags?

Anti-arson letterboxes and bags are protective devices which are designed to eliminate the threat of arson by containing and extinguishing any potential threat that is posted through the mail delivery slot. The purpose of these devices is to contain incendiary materials, such as fire-starting liquids or explosive substances, from being introduced into a building through the mail slot. Anti-arson letterboxes and bags are designed to be installed on the back of entrance doors or letter openings. There are two models of anti-arson mailboxes available; mailboxes with integrated automatic extinguishers and mailboxes with an intumescent bag design.

How does a fireproof letterbox work?

• Mailboxes with integrated automatic extinguishers - the extinguisher is activated once heat is detected.
• Mailboxes with an intumescent bag design - the bag material swells through the heat and suffocates the fire.

How to prevent fire through letterbox?

Avoid being the target of a fire through your letterbox by installing an anti-arson letterbox, also known as anti-arson mailboxes. The letterbox is designed to catch the burning liquid and extinguish the fire, before it has chance to spread to the rest of the premises. One of the larger fire risks in business districts and sometimes even in residential areas is arson, and sadly not only during riots. Usually, a flammable liquid such as petrol is poured through the letter box and then set alight with a lit rag which is pushed through the letterbox. Arson endangers lives and property, and in the case of an arson attack through the front door, the fire will actually block the main route of escape, increasing the risk to people even more.
