Lock Out Tag Out (LOTO) is a primary function for safe diving operations when working on or nearby an energy source. The energy source can be hydraulic, Pneumatic, Electrical, Suction / Discharge, differential pressure (DELTA P), stored energy or environmental power such as tidal stream (on rotating propellers). If it is not isolated and LOTO correctly, it will injure or potentially kill the diver. When a robust LOTO system is used, diving operations can be carried out with the assurance that the hazard has been isolated and it is safe to dive. There are however, several steps to a robust LOTO system. This course will take you through these steps and will enable you to implement a safe system of work and LOTO System at your work site.
