Under what condition should work on electrical equipment in sewer systems be performed?

Work on electrical equipment in sewer systems should only be performed when a person knows what they are doing, is qualified, and has the necessary authorization. This requirement exists due to the inherent hazards associated with electrical work, especially in environments such as sewer systems where conditions can be unsafe due to moisture, confined spaces, and potential exposure to hazardous substances.

Qualified personnel have the training and knowledge to identify risks, use safety equipment properly, and implement the necessary precautions to protect themselves and others. Authorization typically ensures that the person has permission to work on the equipment and follows the established protocols for safety and operational integrity. By adhering to these criteria, organizations can minimize the risk of accidents, injuries, or equipment damage, thereby promoting a safer working environment for everyone involved.
