A working enclosure adapted to provide a clean air zone within a potentially hazard environment such as an oil storage tank, the enclosure comprising a canopy (10) supported by a frame (11) and having a skirt (12) to be held in close proximity with the tank wall by magnetic pads (13). An operator may enter and leave the canopy via an air lock (33), and a supply of clean air from a fan (23) is supplied to the interior of the canopy by an inlet duct (20) and maintained at a slight over pressure therein by a controlled air outlet duct (30). In the clean air zone created by the enclosure an operator on suspension lines (18) may carry out "hot work" on the tank wall while the supply of clean air is monitored, and the operation shut down automatically in the event of air contamination.
