The manual is the sixth of six student manuals for use in a course on occupational health and safety for supervisory personnel. The manual contains lessons 12 and 13 of the 15 consecutively-numbered lessons, each of which contains study questions (and answers) interwoven with the text and review questions at the end of each section. Lesson 12 provides information about techniques of communicating the contents of the Occupational Safety and Health Act to employees so that they will both understand the law and comply with its provisions. Lesson 13 covers the how and when of providing safety and health training, especially in the case of employees performing new jobs, and discusses ways of making and keeping employees aware of hazards.
