The document outlines lock out tag out (LOTO) procedures for electrical work on the Opera Grand Tower Project in Downtown Dubai. It assigns responsibilities for the LOTO system and describes permit requirements and processes. Key elements include appointing authorized engineers and competent persons, implementing safe isolation procedures before work, maintaining a permit log book, and having emergency response plans and contact details. The goal is to ensure electrical hazards are controlled whenever employees or others could be exposed to risks like electric shock or burns during work.

• Fire
• Explosion
that the work situation is assessed and that suitable control measures' and
systems are implemented to ensure that electrical risks / hazards are
removed or reduced as far as reasonably practicable.
The ‘Lock Out / Tag Out’ procedure is implemented in situations where a
part of the Electrical System has been made LIVE before the work on the
system has been completed and RCC has assumed the role of ‘Duty
Holder’ for the installation.
The electrical system energized rooms keys will be under the control of RCC,
permit system to be followed to work in the rooms by all parties.
