High Voltage Safety-Operational Level (HVS-O) MENG 1390

Marine Engineering Part-time Studies Course

Course details

This course meets the training, understanding, and proficiency as set out in the Transport Canada High Voltage Safety Training TP 15326 (05/2016), Part 4: High Voltage Endorsement, and requirements of STCW 2010, Manila amendments (Tables A-111/2 and A-111/6), for electrical, electronic, and control systems at the operational level. HVS-O explains the safety requirements necessary for working on ships with High Voltage (HV) electrical systems; including the hazards associated with HV, the requirements outlined in CSA Z462-18: Workplace Electrical Safety. This course provides knowledge of the electrical systems and typical voltages found on board vessels, the protocols around lockout, permit to work, and authorized and competent person. The course also includes a brief introduction to risk assessment, safety documentation and records, HV isolation process, and the importance of a circuit main earth. HV-approved test instruments and personal protective equipment (PPE) are also used in this course. ​
