  • Why You should take this seminar

    This course meets the safety training requirements for employees bound by OSHA rule 1910:331-335. Learn how current NFPA 70E standards apply to a facility, why safe electrical work practices are important, and what can be done to ensure your organization meets all government standards for electrical safety.

    Electrical safety training provides you with the education needed to complete your job safely. Training is required for employees working with electricity and who face comparable risk of injury due to electric shock or other electrical hazards. The lack of proper training can be costly, and can result in damage to equipment and property. More importantly, proper training can reduce the risk of serious injury or loss of life.

    OSHA’s mandated training requirements apply to employees who face a risk of electric shock that is not reduced to a safe level by the electrical installation requirements of 1910.302 through 1910.308. The rules also apply to utilization of electricity and are for any installation at any voltage in your facility, including high voltage.
