Tunneling machines - Shield machines, thrust boring machines, auger boring machines, lining erection equipment - Safety requirements

The DIN EN 12336:2005 standard, published by the German Institute for Standardization (DIN), outlines the safety requirements for tunnel boring machines (TBMs), including shield machines, thrust boring machines, auger boring machines, and lining erection equipment. This standard, effective from August 1, 2005, is crucial for ensuring the safety and reliability of machinery used in tunnel construction and underground engineering projects.

It provides comprehensive guidelines for the design, construction, and operation of these machines, emphasizing the importance of risk assessment and mitigation. The standard covers various aspects such as machine stability, emergency stop systems, and protection against hazardous conditions like rock falls and water ingress. Additionally, it includes requirements for operator training, maintenance procedures, and the use of personal protective equipment (PPE) to minimize risks to workers.

By adhering to DIN EN 12336:2005, manufacturers and operators can ensure that tunnel boring machines are safe to use, thereby reducing the likelihood of accidents and enhancing the overall efficiency of tunneling operations. This standard is widely recognized and implemented across Europe, contributing to the harmonization of safety practices in the construction industry.
