What are the fireproof stickers on the distribution box

Fireproof stickers, also known as fire suppression stickers, are designed to extinguish electrical fires in distribution boxes and prevent them from spreading.

Purpose and Function

Fireproof stickers are strategically placed inside electrical distribution boxes or on appliances that may pose a fire risk, such as fridges, freezers, washing machines, and tumble dryers . Their main purpose is to detect and suppress fires quickly, reducing the risk of fire spreading through electrical circuits or enclosed spaces .

How They Work

These stickers contain a special chemical compound that reacts when exposed to high temperatures, typically around 380°C. When a fire starts, the heat triggers a chemical reaction that releases harmless inert gases, which envelop the fire and extinguish it within seconds . This rapid response helps prevent damage to the distribution box and connected circuits. Some fireproof solutions, like intumescent strips, expand when heated to form a protective barrier, sealing off cable entries and preventing fire propagation within the unit . Both types of products are tested to meet European and British safety standards and are designed to last for several years, often around five years .

Installation and Safety

For maximum effectiveness, fireproof stickers must be installed in precise locations inside the distribution box or appliance. Professional installation by someone experienced in electrical fire safety is recommended to ensure the fire is detected and suppressed immediately . Proper placement ensures that even small sparks or overheating components trigger the sticker before a fire can spread.

Benefits

• Immediate fire suppression in electrical distribution boxes
• Prevention of fire spread to other circuits or appliances
• Peace of mind for homeowners and businesses
• Compliance with safety standards and regulations In summary, fireproof stickers are a proactive fire safety measure for electrical systems, providing rapid suppression of fires in distribution boxes and reducing the risk of extensive damage or injury .
