Fire bags and pillows

When a fire breaks out in a building it is important to prevent the spread of it as much as possible. By limiting the speed of it spreading and containing the fire to a single area, companies can minimise the damage caused. This may make it easier to deal with the fire with onsite fire extinguishers in the case of a relatively minor incident or else keep the fire under control until the fire services answer an emergency call and arrive on site. 

The use of passive fire protection products and devices can be remarkably effective in meeting these objectives. For example, fire bags and pillows can be placed within the walls and ceilings of a building to prevent the passage of a fire and protect valuable cables.

But how do they work?

Fire Bags
Fire bags are made of different sized coated glass cloth bags, integrated with a mixture of durable intumescent and inert fillers. They act as a seal fitted around complex penetrations in walls and help to protect highly sensitive cable trays and electric cables. The bags can provide up to 2 hours of fire resistant protection, allowing time to contain and suppress the fire. 

Fire Pillows
Fire pillows are designed to protect metal services and cables for up to 4 hours, preventing a fire from moving through compartment floors and walls. This gives companies and fire services an invaluable period of time in which to extinguish the fire before any cables get damaged. The intumescent material used within the pillows expands and hardens to form a protective layer, safeguarding cables effectively.

The use of fire bags and pillows to protect important cables within walls and ceilings is extremely important in the safe guarding of business assets and should be used in a fire safety plan to protect a building.
