Which of the following is not a condition necessary for Static Arc Ignition?

In the context of Static Arc Ignition, the correct answer pertains to the conditions that are crucial for this phenomenon to occur. Static Arc Ignition requires specific elements to successfully ignite a flammable mixture.

The first condition, the means of static generation, is essential as it provides the source of the charge needed for ignition. Without this, there would be no static electricity to create an arc.

The coexistence of the arc and fuel source is also critical, as the arc must be present where there is a combustible substance for ignition to take place.

Static discharge with sufficient energy is another necessary requirement; an arc must discharge enough energy to initiate combustion in the fuel source.

On the other hand, the presence of water is not a necessary condition for Static Arc Ignition. Water is generally known to be a fire suppressor due to its cooling properties and its ability to displace oxygen. Therefore, while water can influence the behavior of fire, it is not a requisite for the occurrence of Static Arc Ignition. In fact, water can help prevent ignition rather than facilitate it, making it an incorrect answer in this context.
