The Hazmat Medical Life Support basic provider course book aims to equip medical responders to a hazmat incident -- chemical, radiological or biological -- with essential skills and knowledge to safely and effectively manage casualties. It includes basic information about hazmat agents and provides easy to remember algorithmic approaches for the on-scene management of a hazmat event. Essential information on setting up medical operations, triaging and approach to hazmat casualties, personal protective equipment, decontamination, wound management, life support as well as paediatric-specific issues are presented in this book. In this second edition, the content have been revised and updated but still keeping to the same basic approach targeted at medical personnel who are first responders or receivers to hazmat events. New resources especially regarding chemical weapons, antidotes as well as biological agents have been added to keep up to date with current practices. The systematic and practical approach as well as the focus on basic and key issues for specific hazmat agents would be useful foundational training for all levels of medical responders.
