Abstract: Apparatus is provided which comprises a container arranged to contain a material dispensable as a spray, aerosol or particulate through an outlet aperture, and a spacer member, wherein the spacer member is movable between a first position which is convenient for carrying and/or storage and a second position which determines a minimum distance between the outlet aperture and the target surface area or object for the spray, aerosol or particulate. Preferably, the spacer member when in the first position can inhibit the spray, aerosol or particulate from directly impacting the target surface, area or object.

Abstract: A hazard detector assembly for attachment to a surface within a protected zone comprises a detector unit and a test stimulus generator unit.
