Engineering L 4 – Safety Review Safety Video Safety test n OBJECTIVE n DRILL: : Safety Identify three important safety rules to follow while working in the Technology Lab

Before we begin to study drafting it is important to spend a little more time on General Lab Safety n Last class we discussed the following important safety items: - Upon entering class immediately have a seat and complete daily drill. - Never touch class tools equipment without teacher permission. - Only use equipment that teacher has demonstrated. - Use tools / equipment as directed and for purpose tool is intended. - If you have a question on how to use equipment, tools or how to do a procedure ask for teacher instruction.

How many of the following rules did we get? n n When working around machines with moving and/or spinning parts be sure to secure dangling jewelry, long hair, loose clothing, and remove accessories that might get caught. When working with equipment focus on what you are doing. Do not speak to people operating machines. Stay out of machines ‘Safety Zone’(3 foot perimeter) if you are not directly involved in operation. Immediately report all accidents/ injuries to

A few more important safety items n n n n Tools for cutting should be sharp…Dull tools cause injuries Wear safety glasses Return tools and equipment to proper location as soon as you are finished using it! Do not carry long stock by balancing it in center. Wear an apron to protect / secure clothing Do not put sharp tools or hot items near neighbors, face, or handle carelessly. Do not use electrical tools or items in such a
