WHY DO WE NEED FLAME RETARDANTS?

On average, there are more than 4,500 fatalities annually in the EU-27 as a result of fires; this accounts for 2% of all fatal injuries. Fires develop from inception through build-up, until a stage where the total thermal

radiation from the fire-plume, hot gases and hot compartment boundaries cause the radiative ignition of all exposed combustible surfaces within the compartment. This sudden and sustained transition of a growing fire to

a fully developed fire is called flashover. At this point, the radiation of energy to the contents of the room raises all the contents to their ignition temperature, whereby the contents of the room suddenly and simultaneously ignite. It is estimated that in a domestic dwelling fitted with working fire alarms on all levels where the occupants are asleep upstairs and a fire starts on the main level of the residence, the occupants have about three minutes

to escape if they are to have any chance of survival. The presence of flame retardants in otherwise combustible materials has two possible effects;

 

The flame retardant may prevent the fire from developing altogether or;

The flame retardant may slow down the build-up phase of the fire by delaying the onset of flash over, thereby extending the escape time window.

 

In either case, the flame retardant serves its primary purpose of reducing the risk of fire-related fatalities. 

 

The efficacy of the use of appropriate flame retardants can be seen by way of example from the introduction of The Furniture and Furnishings Fire Safety Regulationsin the UK in 1988. These imposed a fire resistance requirement on all upholstered furniture supplied in the UK. Between 1988 and 2002 a government commissioned report estimated that the Furniture and Furnishings Fire Safety Regulationsplayed a direct role in saving 1,150 lives and preventing 13,442 injuries.
