High expansion foam fire-fighting equipment is provided to obtain a desired foaming magnitude and a high expansion foam as designed even if smoke is included in the air inside a discharge section. High expansion foam fire-fighting equipment includes a spray nozzle(9), a channel drum(2) and a foaming net(7). Foam aqueous solution(Wg) is transferred by the spray nozzle. A foam extinguishing chemical(16) including water(W) and a surfactant(18) is mixed in the foam aqueous solution. The spray nozzle is built in the channel drum, which sucks the air(K) inside a discharge section(1) by discharging the foam aqueous solution from the spray nozzle. The foaming net(7) is installed on the channel drum, and the foam aqueous solution discharged from the spray nozzle collides with the foaming net.
