Minimizing electrostatic charge formation is critical in various industrial settings to prevent potential hazards like explosions or equipment malfunction. Humidification of the atmosphere is effective because increasing moisture content reduces the likelihood of charge build-up. When humidity levels are higher, water molecules in the air can attach to dust and other particles, allowing for better charge dissipation. This makes it harder for static electricity to accumulate, as water is a good conductor of electricity, aiding in the equal distribution of electrical charges.

In contrast, options like using standard water features, regularly cleaning equipment with alcohol, or increasing flow velocity do not directly target the issue of static charge management in the same effective way. Water features may not provide consistent humidity levels, cleaning with alcohol might strip away residues but won’t help with static reduction, and increasing flow velocity can actually generate more charge rather than mitigate it. Thus, humidifying the atmosphere is a practical and scientifically sound method for minimizing electrostatic charge formation.
