On-Site Training

DYMAX's electrical safety training personnel can teach your people safe operating procedures and inform them about recommended maintenance practices. We can customize a training program to meet your employees' and facility's needs.

Be sure your people know how to perform their jobs safely. A thorough understanding of your electrical system and equipment is essential for maintaining its reliability and avoiding costly mistakes.

Compliance with OSHA involves adherence to employee training requirements . Arc flash hazard training is regulated under OSHA 29 Code (CFR) Part 1910 Subpart S. Included in the code is: (1) a facility must provide, and be able to demonstrate, a safety program with defined responsibilities, and (2) workers must be trained on the hazards of arc flash. DYMAX will teach your employees about arc flashes, arc flash prevention and the types of personal protective equipment (PPE) required.

DYMAX most often receives requests for training on electrical safety and on the familiarization with and safe operation of electrical equipment. A full understanding of the equipment under examination, including its interconnecting circuitry, is essential to safe operation. Possession of an up-to-date one-line diagram of the facility's electrical system is essential. We can explain the function of each circuit element so that troubleshooting, when needed, can be more logically and carefully pursued. We can point out potential hazards so that work can be conducted in the safest, least threatening manner.
