Which of the following represents the accepted method of cleaning dust and foreign particles from electrical equipment while limiting damage to electric components?

AUsing a vacuum cleaner to remove debris from the components.
BCarefully using a soft copper bristle brush.
CBlowing a high velocity stream of compressed air rapidly across the components.
DUsing carbon tetrachloride as a cleaning solvent to clean the components.
AI Explanation

The correct answer is A) Using a vacuum cleaner to remove debris from the components. The use of a vacuum cleaner is the accepted method for cleaning dust and foreign particles from electrical equipment, as it effectively removes debris without risking damage to sensitive electric components. Vacuum cleaning is a gentle and controlled approach that avoids the potential hazards of the other methods, such as the risk of static discharge from compressed air or the corrosive effects of chemical solvents. The other options are not recommended for cleaning electrical equipment. B) Using a soft brush can potentially dislodge and scatter particles, C) high-velocity compressed air can force debris deeper into the equipment, and D) carbon tetrachloride is a hazardous solvent that can damage and corrode electrical components.
