Electrical Safety Training Course 70E-2021

Reference Docs: NFPA 70E-2021; OSHA 1910 Subparts ‘S’, ‘J’ & ‘I’; OSHA 1926 Subpart ‘V’

Price: $275 / Seat

Course Overview:  This course introduces attendees to the methods used to identify the shock and arc-flash ‘hazards’ & ‘risks’ associated with electrical energy, and work practices to establish an electrically safe work condition (ESWC). “Incident Energy” and “Limits of Approach” as defined on equipment Incident Energy (IE) labels, or using the arc flash personal protective equipment (PPE) categories method, are discussed along with the guidance on selection and use of personal protective equipment. Application of a lockout/tag out (LOTO) program along with job safety planning and job briefing requirements are also addressed to reduce the risk(s) of injury or damage to health from electrical hazards.  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 of arc-flash label examples, tables identifying Shock Protection Approach Boundaries and Arc-Flash PPE Categories for AC & DC Systems, arc-rated protective clothing levels, rubber glove class & chart, and procedures to establish an ESWC. 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 outlined in NFPA 70E.
