Self-Contained Breathing Apparatus (SCBA) Set

An SCBA set carries its own breathing air supply, letting a wearer enter a smoke-filled building, confined space or chemical-fume atmosphere that would be immediately dangerous without it. The full-face mask runs in positive-pressure mode — always pushing filtered air out through any gap rather than letting contaminated air leak in — with a pressure gauge and low-air alarm whistle so the wearer always knows how much time is left. Standard kit for trained fire response teams, confined-space entry crews and industrial rescue squads.
