The unexpected startup of mechanical or electrical equipment poses a significant danger as it can lead to accidents. When equipment starts up without warning, operators and personnel may not be prepared for its operation, which increases the risk of injury. For instance, if someone is working near machinery that suddenly begins to function, they could be caught in moving parts or become involved in hazardous conditions, resulting in serious accidents. Moreover, this kind of unexpected behavior can disrupt workflows and create panic among staff, compounding safety risks.

While overheating, reduced efficiency, and increased energy costs may also be consequences of mechanical or electrical issues, the immediate concern is the safety of personnel. Accidents can lead to injuries or fatalities, making this the most critical potential danger associated with an unexpected startup scenario.
