Electrical Safety Training Course 70E-2021: Contact Release
ELECTRICAL SHOCK and CONTACT RELEASE TRAINING, 4 Hour
Reference Docs: NFPA 70E-2021 edition “Electrical Safety in the Workplace”;
- OSHA 1910 Subpart ‘S Electrical’
- OSHA 1910.137 ‘Personal Protective Equipment’
- OSHA 1926 ‘Safety and Health Regulations for Construction Subpart K Electrical’
Course Overview: This course explains the concept of “contact release” as part of the emergency response training. Risk Management within the workplace is addressed along with the methods used to identify those shock ‘hazards’ & ‘risks’ associated with electrical energy. Risk Assessment processes are reviewed and procedures of ‘contact release’ are demonstrated. In addition, updates to the NFPA 70E- 2021 edition are reviewed within the presentation.
Attendees receive a hard copy workbook that follows the presentation and allows room to take notes. The workbook also includes attachments addressing Approach Boundaries, Shock/Arc-Flash Labels explained, Protective Rubber Equipment and Protective Clothing used, and Electrical Blankets and Matting. A student group proficiency exam is given at class end and certificates are provided to those students completing the training. The end customer also receives documentation, along with the student roster, for file to meet employer record keeping requirements for employee(s) training as required by OSHA.
