Where should automatic sprinklers be installed in relation to rubbish and linen chutes?

Automatic sprinklers should be installed at the top and terminal rooms of rubbish and linen chutes to effectively manage potential fire risks. The primary function of sprinklers in these areas is to suppress flames and prevent the spread of fire that may originate in the chute or nearby storage.

By placing sprinklers at the top of the chute, any fire that starts down in the chute receives immediate attention, as the heat from the flames will rise and trigger the sprinkler system. Installing these systems in terminal rooms also ensures that any fire that reaches the end of the chute can be effectively managed before it spreads further. This strategic placement is crucial, as rubbish and linen chutes can facilitate the rapid transfer of fire and smoke between floors if not properly protected.

Other options suggest various placements that do not provide the same level of protection or effectiveness as having sprinklers installed at both the top and terminal rooms. This ensures a comprehensive approach to fire safety in these potentially hazardous areas.
