Protected Space

Protected area is an area (an installation or part of an installation) within a protected space which is required to be protected by the system. Note: For internal combustion machinery, typical protected areas are hot surfaces such as exhaust pipes without insulation, or with insulation fitted in accordance with SOLAS regulation II-2/4.2.2.6.1 that is likely to be removed frequently for maintenance, and high-pressure fuel oil systems installed near hot surfaces. For typical diesel engines, such areas would include the area on top of the engine, the fuel injection pumps and turbo chargers, unless the fuel injection pumps are installed in a sheltered location beneath the steel platform. For boiler fronts and oil-fired inert gas generators, typical protected areas are hot surfaces around the burners without insulation, or with insulation fitted in accordance with SOLAS regulation II-2/4.2.2.6.1 that is likely to be removed frequently for maintenance. Boiler fronts should be interpreted as the boiler burner location irrespective of the boiler design. For incinerators, typical protected areas are hot surfaces around the burners without insulation, or with insulation fitted in accordance with SOLAS regulation II-2/4.2.2.6.1 that is likely to be removed frequently for maintenance.
