Machinery for road construction. Mixers for road construction materials. Safety requirements

This document specifies the fundamental safety requirements applicable to stationary and mobile equipment designed for the production of asphalt concrete and other road construction materials. The standard establishes criteria to ensure the safety of personnel operating, maintaining, and inspecting such machinery within industrial settings. It addresses hazards related to mechanical components, electrical systems, and control mechanisms inherent to mixing units used in pavement engineering. Specific provisions cover guarding of moving parts, emergency stop functions, and safe access for routine servicing. The text delineates the necessary protective measures to prevent accidents during normal operation and foreseeable abnormal conditions. It applies to manufacturers, regulators, and users involved in the supply and deployment of mixing plants for road building. Compliance with these technical specifications aims to minimize risks associated with the handling of aggregates, binders, and hot materials. The document serves as a reference for aligning national regulations with established international safety principles in the field of heavy road construction machinery.
