Suggest two ways to reduce the possibility of “electric shocks” experienced by shoppers when they touch the railings.

Grounding: One of the most effective ways to prevent electric shocks is by properly grounding the railings. This involves connecting the railings to the ground to ensure any stray electrical charge can be safely dissipated. This can be done by a professional electrician who can ensure that the grounding is done correctly and safely.

Insulation: Another way to prevent electric shocks is by insulating the railings. This involves covering the railings with a non-conductive material like rubber or plastic. This prevents the electrical charge from being transferred to anyone who touches the railings. It's important to ensure that the insulation is maintained and replaced if it becomes worn or damaged.
