### sec.261 Using plant powered by internal combustion engines The underground mine manager for an underground mine must ensure plant powered by a non-explosion-protected internal combustion engine is used— only in a NERZ at the mine; and only if— the engine is— a compression ignition type; and clearly marked as a non-explosion-protected engine; and any hazard controls for the plant’s operation as decided by a risk assessment mentioned in section 260 (2) (f) are implemented; and for plant that is mobile equipment—access by the plant into an ERZ1 is prevented by a system that is either fail safe or includes multiple redundancy devices. The underground mine manager must ensure an internal combustion engine used to power plant in an ERZ1 is— a compression ignition type; and a type that has been tested by a nationally accredited testing station under AS/NZS 3584.2:2008 ‘Diesel engine systems for underground coal mines—Explosion protected’; and assessed by the engine’s manufacturer, having regard to the recognised standard for explosion-protected diesel engine systems, as safe to use in an ERZ1; and clearly marked with information identifying— the test report for the test mentioned in paragraph (b) ; and the assessment report for the assessment mentioned in paragraph (c) . The underground mine manager must ensure an internal combustion engine is not used to power plant in an ERZ0. (sec.261-ssec.1) The underground mine manager for an underground mine must ensure plant powered by a non-explosion-protected internal combustion engine is used— only in a NERZ at the mine; and only if— the engine is— a compression ignition type; and clearly marked as a non-explosion-protected engine; and any hazard controls for the plant’s operation as decided by a risk assessment mentioned in section 260 (2) (f) are implemented; and for plant that is mobile equipment—access by the plant into an ERZ1 is prevented by a system that is either fail safe or includes multiple redundancy devices. (sec.261-ssec.2) The underground mine manager must ensure an internal combustion engine used to power plant in an ERZ1 is— a compression ignition type; and a type that has been tested by a nationally accredited testing station under AS/NZS 3584.2:2008 ‘Diesel engine systems for underground coal mines—Explosion protected’; and assessed by the engine’s manufacturer, having regard to the recognised standard for explosion-protected diesel engine systems, as safe to use in an ERZ1; and clearly marked with information identifying— the test report for the test mentioned in paragraph (b) ; and the assessment report for the assessment mentioned in paragraph (c) .
