Expert Solution & Answer
To determine
The appropriate gears required to be worm while working with any cleaning solvent or chemicals.
Explanation of Solution
Prior to using any cleaning solvent we should always use protective gloves and goggles to prevent any health hazard occurring due to the chemicals contained in the cleaning agents that can be dangerous for our eyes and skin too.
