The aim of BSTR is to review and build on previously gained knowledge and skills from BST through theoretical and practical training. The GWO Basic Safety Training Refresher is divided into the following 5 modules: (1) First Aid Refresher: The aim of this BSTR First Aid Module is to refresh the participants prior experiences, knowledge, skills, and abilities to enable participants to recognise signs and symptoms of life threating situations and administer safe and effective first aid in the wind turbine industry/WTG environment in order to save lives, preventing further illness or injury, until the casualty can be handed over to the next level of care in case of an incident in the wind turbine industry/WTG environment. (2) Manual Handling Refresher : Delivery of the Manual Handling Refresher Module covers same content, duration, learning objectives as described in BST Manual Handling. (3) Fire Awareness Refresher: Delivery of the Fire Awareness Refresher Module covers same content, duration, learning objectives as described in BST Fire Awareness. (4) Working at Heights Refresher: The aim of this BSTR Working at Heights Module is to review and build on previously gained knowledge and skills through theoretical and practical training so that participants can use basic personal protective equipment and perform safe work at heights and safe and comprehensive basic rescue from heights in the wind turbine industry/ WTG environment. (5) Sea Survival Refresher Upon completion of the Global Wind Organisation (GWO) Basic Safety Training Refresher (BSTR) participants will possess an awareness of the hazards encountered when working within the wind industry and how to control and mitigate these hazards. The BSTR will also equip participants with the knowledge, skills, and confidence to appropriately respond in the event of an emergency and to increase their safety through proper use of Personal Protective Equipment (PPE), emergency equipment and procedures.
