Medium / High Voltage Safety Training – 4 Hrs

We Offer Medium / High Voltage Safety Training in all 50 States!

Our Medium / High Voltage Electrical Safety Training establishes minimum standards to ensure that worker’s health and safety are protected during medium voltage electrical work and is based upon, but not limited to, OSHA 1910.269, 1910.132(D), and 1910.137 standards. OSHA makes a distinction between low voltage qualified employees (600 volt and below) and those qualified for medium / high voltage job tasks. The reason for this distinction is equipment and conductors that carry medium / high voltage warrant particular safety requirements and procedures. Electricians may only be licensed for particular voltage classes in some jurisdictions. There are many issues to consider when measuring medium / high voltage. Taking medium / high voltage measurements can be hazardous to the equipment, to the unit under test, and to the employee. Also verifying zero energy, proper grounding techniques, and proper switching procedures is critical to the safety of the employee. Pre-requisite to this class is NFPA 70E Training.

OSHA Final Rule (April 1, 2014) harmonizes personal protective equipment (PPE) standards between the construction and general industries. OSHA reasoned that PPE standards for electrical power work should be as similar as possible between these two industries because the work performed by employees is practically identical.

Upon Completion Of Medium / High Voltage Safety Training Students Will Be Able To:

  • Use of insulating and shielding materials for employee protection. Identify medium / high voltage safety hazards.
  • Define the approach boundaries.
  • Demonstrate the skills and techniques to distinguish live parts from other parts and determine the nominal voltage of live parts.
  • Selection of appropriate personal protective equipment (PPE) for each hazard category.
  • Demonstration of safe electrical work practices working on or near energized equipment.
  • Proper selection and use of rated test instruments and equipment.
  • Use of insulating and shielding materials for employee protection.
