A refuge unit (10) has an outer structure (12) and an inner structure (14). The inner structure (14) is rotatable relative to the outer structure (12) about an axis of rotation (16). The inner structure (14) is capable of accommodating one or more people. The inner structure is biased toward a substantially constant rotational position about the axis (16) such that if the axis (16) lies in horizontal plane, a floor (18) of the inner structure also lies in a horizontal plane. One or more doors (40, 40') are provided at respective opposite entrances to the unit (10). |
