Electrical Safety Training

Explain how electrical current affects the human body, comparing dry and wet skin resistance, and how magnitude, voltage, duration, and body routes determine risks like ventricular fibrillation.

This lecture explains electrical hazards, including electrical shock and electrocution, the effects of current, path, and duration, and lockout-tagout procedures and PPE to prevent injuries, fires, and falls.

Identify the main causes of electrical fires, including short circuits, overloading, equipment contact failures, and leakage current, and learn safe practices and proper extension cord usage to prevent incidents.

Ensure safety via earthing and grounding, creating a low-resistance fault path with protective devices. Measure grounding resistance with the fall-of-potential method and maintain records per standards.

Explore protective devices such as RCCB, RCBO, and MCB, plus surge protection devices, and learn about lockout/tagout systems to safeguard people and equipment during abnormal electrical conditions.

Master the use and inspection of personal protective equipment and insulated electrical tools for safe work on systems from low to high voltage, including gloves, mats, testers, and rescue hooks.

Explore safety precautions for domestic installations, including using approved equipment, earthing with two connected earth plates under one ohm, cable management, limited outlets, RCDs and MCBs, and avoiding wet hands.

Discover how to handle electrical emergencies: use CO2 or dry sand for fires and unplug if possible, treat burns, and safely assist shock victims with prompt medical help.

Perform a one-minute safety audit before electrical work by notifying personnel, inspecting equipment, locating exits and alarms, and confirming protective gear, fire extinguishers, and lockout-tagout status.
