Projectile fire fighting system using recoil free launcher - has glass projectiles filled with foam with plastics linings with weak points

摘要

A fire fighting system is for inaccessible or late-discovered fires e.g. airports, highrise buildings. Containers filled with extinguishing foam, are fired from missile launches through windows etc if need be to the seat of the fire as in 2542485. The containers are made of prestressed glass. Preferably the containers are lined outside and/or inside with plastics, e.g. film or foam, the lining having weakened break points. The containers have prestressed glass tips or points so that the containers crumple up on impact. It is also possible to fit the prestressed glass containers with frontal impact bolts which also cause the container to crumble and disintegrate on impact.
