<p>A fire extinguisher comprises a tubular body (2) having a cylindrical wall (3) and containing extinguishant. A detonator tube (12) is mounted coaxially within the tubular body (2). Longitudinal and transverse score lines (20a,20b) define a zone of weakness in the wall (3). Upon detonation of the detonation tube (12) the wall (3) of the body (2) ruptures preferentially in the weakened zone so that extinguishant is discharged in a predetermined direction over a predetermined area.</p> |
