Knowing what a fire sealing compound is will help you to have better passive fire protection. These compounds use a mixture of materials designed to fill and seal gaps in openings where cables and pipes go through floors and walls.
Like other types of firestops, fire sealing compounds are used to fireproof sections of a building. This is a process called fire compartmentation.
Fire sealing compounds do this by forming a rigid seal. This seal is designed to prevent the spread of fire and smoke. Unsealed penetrations by pipes or pipe services greatly hinder the ability of a firestop barrier to contain a fire.
Even if your workplace has firestops, there is a much larger chance that a fire will spread throughout the building if they remain unsealed.
What is a Firestop?
Firestops are a form of passive fire protection that aims to contain the spread of smoke and fires by compartmentalizing rooms. Fire stopping is an essential aspect of having adequate fire safety in a structure.
Because of how dangerous fires can be without any form of fire stopping, regulations require all buildings in the UK to have adequate fire-stopping and passive fire protection.
Types of Firestops
There are a variety of methods and products that function as firestops. This includes fire doors, fire barriers, batt and mastic, and fire sealing compounds.
All types of firestops have their own benefits and uses, and each type is more suitable for some types of buildings over others. Fire sealing compounds are often used in conjunction with these other fire-stopping methods. This better seals and compartmentalizes rooms.
This includes sealing unprotected openings in or around a firewall, fire barrier, or fire door.
Firestops are designed to contain fires and prevent them from spreading past their point of origin. This helps slow down the rate at which flames and smoke spread.
By slowing the spread of the fire, those inside have more time to escape the building, and damage to the structure of the building is reduced.
Fire stopping compounds include materials like intumescents, silicone, mineral fibres, and rubber. These compounds are effective firestops because they produce a layer containing a high amount of carbon when exposed to high temperatures.
