Safety management systems (SMS) and human factors (HF) disciplines are often regarded as subjective and nebulous. This perhaps stems from a variety and sometimes disjointed activities in the realms of education, industry and the research practices. Aviation is one of the safety-critical industries that have led the development of safety systems and human factors. However, in recent years, SMS and HF is seen to be progressing well in the road, rail and even the medical arena. This book is a wide-ranging compendium of contemporary SMS and HF approaches from the aviation, road, rail and medical domains.
