This booklet represents a simple tool for a worker who finds himself rescuing a colleague. When needed, it’s fundamental to know what to do, how to act and, above all, what to avoid. Therefore, the booklet contains a series of "behavioral sheets" providing information about the appropriate first aid procedures to be applied in case of accidents or illnesses, waiting for paramedics to come. In order to better clarify the operating techniques, 50 photos have been added.
