3. It is probable that the best time to introduce a safety precaution is just preceding the work where the caution is to be observed. Pointing out and discussing hazards much in advance of the time when they will occur does not make lasting impressions upon most learners. Likewise, it is not advisable to defer the discussion of safety precautions until the end of the lesson or demonstration and expect to have the learners realize their importance after the need for observing them has passed.
4. The reasons for observing a safety precaution should be given at the time the precaution is introduced. The statement that this or that practice is unsafe will not usually convince the learner of the importance of the precaution.
5. If instruction sheets are used, safety precautions should be written in the appropriate places, again not at the beginning or the end, but exactly at the point where the caution is to be observed.
6. In the ensuing steps of the lesson and during the entire class period, no violation of a safe practice by a learner should be allowed to go unnoticed or unchallenged by the teacher.
7. The teacher should organize special lesson on safety, such as the personal safety of the student, the general rules of safety in the shop, the fire drill, and others.
8. The organization of a safety committee is highly desirable; there should be a rotating membership so that all students may participate. Give class instruction in the duties and organization so that the student may have knowledge of the procedures and give their cooperation. Such committees should have special responsibility for alerting teacher and student to any unsafe conditions which may develop.
9. Personally, devote at least a full period with each class the check the entire shop for safety conditions. This should include inspection of hand and machine tools and all other equipment or conditions which may be unsafe or which may be made safer. Have a definite lesson plan for this and, if practicable, organize a checking form which may be used as a guide for the students.
10. The safety factors are just as important for older students as for the younger. Therefore, the instructor, even with extension students, should review and emphasize them.
