2.7 Instructor Message

In the previous lesson, we saw the tragic rooftop incident—how a single unchecked assumption during permit approval led to a fatal fall. We learned how signing a permit without visiting the site can turn a routine task into a life-threatening one.

Now, let’s look at another case. This time, it’s not about risk is very difficult to identify with naked eyes—it’s about underestimating electrical risk. Two young engineers, confident in their routine, decided to proceed with cable termination inside a live MCCB panel—without proper authorization, PPE, or supervision. One small mistake. One wrong decision. And both of them lost their lives.

Let us now understand exactly what happened, and what it teaches us about the critical role of risk perception in electrical safety.
