COURSE PROVIDER: Gilbert Gedeon, P.E.
Control of Hazardous Energy - Lockout/Tagout
Course Highlights

This online engineering PDH course presents OSHA guidance on the control of hazardous energy for protecting workers from the release of hazardous energy.


Employees can be seriously or fatally injured if machinery they service or maintain unexpectedly energizes, starts up, or releases stored energy. If the potential exists for the release of hazardous stored energy or for the re-accumulation of stored energy to a hazardous level, the employer must ensure that the employees take steps to prevent injury that may result from such release.


OSHA recognizes the risk of employees being exposed to the release of hazardous stored energy. Therefore, OSHA developed the Control of Hazardous Energy Standard to protect employees from the unexpected energization or startup of machinery or equipment, or the release of hazardous energy during service or maintenance activities.


This 2 PDH  online  course is applicable to employers, building owners, engineers, managers, electricians, construction workers and any other personnel who are involved in servicing and maintaining electrical machinery or equipment.
