Engine Room Vacuum
Whilst running at night in unmanned machinery space mode, service air failed and, amongst other effects, caused the fire flaps to shut. As a consequence, the main engine starved of air and the engine room depressurised. Attending Engineers had difficulty in opening gastight door against partial vacuum. When they eventually got a door partially opened with crowbars, it slammed shut on an Engineer’s hand, severing it at the wrist.
