Step 1: Planning the Lesson Instructional Materials. 1. PowerPoint presentation. 2. Instructor notes. 3. Other materials. Planning the Lesson Presenting the Lesson Evaluate Student Learning and Objectives References Instructional Objectives. 1. Complete the required topics for the OSHA 10-hour course. 2. Complete and discuss the following topics 3. Present Electrocution Hazards to [number] participants. 4. Incorporate active participation in each lesson. 5. Provide a quiz or short evaluation at the end of the course. 6. Ensure feedback from participants at various points in the training Step 2: Presenting the Lesson Lesson Introduction. Introductory remarks or transition from previous lesson. Learning Objectives/Outcomes. 1. After completing this module, students will be able to: a. Identify common electrocution hazards b. Describe types of electrocution hazards c. Protect yourself from electrocution hazards d. Recognize employer requirements to protect workers from electrocution hazards 2. What is the definition of an electrocution hazard? a. Electrocution results when a person is exposed to a lethal amount of electrical energy

2 b. An electrical hazard can be defined as a serious workplace hazard that exposes workers to the following: i. Burns ii. Electrocution iii. Shock iv. Arc Flash / Arc Blast v. Fire vi. Explosion 3. Discuss the major types of electrocution hazards. a. Contact with overhead power lines b. Contact with energized sources c. Improper use of extension and flexible cords 4. Discuss various types of accidents and how they could have been prevented Ex: A fan connected to a 120-volt electrical system via an extension cord provided ventilation for a worker performing a chipping operation from an aluminum stepladder. The insulation on the extension cord was cut through and exposed bare, energized conductors which made contact with the ladder. The ground wire was not attached on the male end of the cord's plug. When the energized conductor made contact with the ladder, the path to ground included the worker's body, resulting in death. 5. Discuss the primary methods to protect workers from electrocution hazards a. Maintain a safe distance from overhead power lines b. Use ground-fault circuit interrupters (GFCI) c. Inspect portable tools and extension cords d. Use power tools and equipment as designed e. Follow lockout/tagout procedures 6. Discuss various tool safety tips when it comes to using power tools and equipment a. Never carry a tool by the cord b. Never yank the cord to disconnect it c. Keep cords away from heat, oil, and sharp edges d. Disconnect when not in use and when changing accessories such as blades and bits e. Avoid accidental starting. Do not hold fingers on the switch button while carrying a plugged-in tool f. Use gloves and appropriate footwear g. Store in dry a place when not using h. Don t use in wet/damp environments i. Keep working areas well lit j. Ensure that cords do not cause a tripping hazard k. Remove damaged tools from use l. Use double-insulated tools Planned Activities, Discussion, or Participant Interaction
