Risks for the additional functions (e.g. scaling, concrete spraying, bolting, charging, drilling, attachments) are not covered in this document.
This document specifies the appropriate technical measures for eliminating or sufficiently reducing risks arising from hazards, hazardous situations or hazardous events during commissioning, operation and maintenance.
This document does not address:
— the additional risks for machines operating in potentially explosive atmospheres;
— air quality and engine emissions.
This document is not applicable to:
— machines constrained to operate by rails;
— continuous miners, roadheaders, drill rigs, conveyors, long wall production equipment, tunnel boring machines (TBM), and mobile crushers.
