Assess­ment of the effec­ti­ve­ness of extin­gu­is­hing addi­ti­ves for class A fires

Water is still the most com­mon­ly used extin­gu­is­hing agent for fire­fight­ing. Depen­ding on the requi­re­ments, extin­gu­is­hing agent addi­ti­ves are available to fire bri­ga­des in the form of addi­ti­ves to increase the extin­gu­is­hing effect. In addi­ti­on to bet­ter extin­gu­is­hing pro­per­ties, water con­sump­ti­on can also be signi­fi­cant­ly redu­ced.
The­re are curr­ent­ly no stan­dar­di­zed stan­dards or regu­la­ti­ons to pro­ve the effec­ti­ve­ness of the­se extin­gu­is­hing addi­ti­ves in fire appli­ca­ti­ons. In seve­ral sci­en­ti­fic stu­dies and the three-year FFG Bridge rese­arch pro­ject “FIRE­TEST”, seve­ral fire tests were car­ri­ed out in the labo­ra­to­ry and in open are­as. Based on this, an auto­ma­ted labo­ra­to­ry test appa­ra­tus was deve­lo­ped, which makes it pos­si­ble to quan­ti­ta­tively mea­su­re the extin­gu­is­hing agent effi­ci­en­cy when extin­gu­is­hing solid fires of fire class A.
