Which of the following is NOT a factor that influences electrostatic charge generation?

1. Equipment malfunction

2. Overfilling

3. Lack of earthing/bonding

4. Agitation

The correct answer is: Equipment malfunction

Equipment malfunction is not a direct factor that influences the generation of electrostatic charge. Electrostatic charge generation typically arises from processes that involve the movement and interaction of materials. This includes aspects such as the physical handling of materials, which can lead to charge separation through actions like friction, contact, and separation processes. Overfilling can lead to spillages or liquid turbulence, both of which may create conditions conducive to charge generation. Similarly, lack of earthing or bonding fails to prevent the accumulation of static charge, making it a critical factor in managing electrostatic hazards. Agitation of materials can also cause charge generation due to increased friction and movement between particles or surfaces. Understanding the specific characteristics that contribute to electrostatic charge generation is crucial in industries where static electricity poses a risk, particularly in environments dealing with flammable materials or sensitive electronic components. The key is recognizing that equipment malfunction, while it can lead to other safety concerns, does not intrinsically cause electrostatic charge to be generated.
