The science of human factors is often overlooked, yet it is pivotal in the pursuit of safety. Understanding what makes us tick, our behaviours and how we interact with others, and the ability to visualise potential threats and errors has many advantages. Such as developing better interpersonal and communication skills, which can assist in growing your leadership or team working skills. The ability to see threats and errors can improve safety, reduce costs, and increase productivity. The Blue Mist is a personal guidebook on human factors; through the author's experiences and research, the reader can explore and learn the basic human factor concepts. Extensive research in well-known disasters such as the Ladbrook Grove rail disaster, The Costa Concordia Grounding, and the Irish Coast Guard helicopter accident, together with the author's accounts of incidents and accidents, combine to give an informative and fascinating insight. The field of human factors developed by the aviation industry is becoming recognised as a critical element in many other sectors. Adopted as a safety element in the shipping, rail, and medical sectors, it has increased safety and reduced accidents. This book assists both novice and experienced human factor advocates and is an excellent tool in exploring the human factor concepts and values.
