Chainsaw Training Module C in accordance with DGUV Information 214-059

Module C of the DGUV is an advanced training course for experienced chainsaw operators who deal with the processing and felling of hazardous or particularly difficult trees. It teaches specialised techniques and knowledge for complex work.

Theory (4 teaching units)

• Legal and safety-related fundamentals

  • In-depth study of accident prevention regulations (e.g. DGUV Regulations 1 and 38)

  • Requirements for work in special environments (e.g. near roads, buildings or on steep slopes)

  • Preparation and implementation of detailed risk assessments

  • Cooperation with other parties (e.g. incident commanders, emergency services, traffic management)

• Tree assessment and risk management

  • Assessment of hazardous trees (e.g. rot, lean, deadwood, cracks)

  • Analysis of external influences (weather, wind load, ground conditions)

  • Assessment of the stability and fracture safety of trees

• Special techniques and tools

  • Fundamentals of cable pulling and winch work to support felling operations

  • Use of aerial work platforms, climbing equipment or machinery

  • Advanced directional notch and felling cut techniques

Practice (12 teaching units)

• Work preparation

  • Securing and organising complex work areas (e.g. in urban areas or on slopes)

  • Planning and preparing the direction of fall under complicated felling conditions

  • Setting up safety measures (e.g. barriers, escape routes)

• Processing of hazardous trees

  • Felling trees with rot or unstable structure

  • Dealing with trees in extreme lean or with damaged crowns

  • Safe removal of deadwood or broken tree parts

• Working with cable pulling and machine technology

  • Use of winches, deflection pulleys and felling aids to control the direction of fall

  • Handling mechanical aids (e.g. aerial lift platforms, tractors)

  • Simple rescue and recovery techniques for accident-damaged tree parts

• Working in special environments

  • Safe working on steep slopes or on unstable ground

  • Felling work near roads, buildings or other obstacles

• Emergency management

  • Rescue techniques for accidents in areas that are difficult to access

  • Cooperation with emergency services and first aid measures
