How can an escalator be retrofitted for safety improvements?

Upgrading safety controls and adding more advanced braking systems is a crucial method for retrofitting escalators to enhance safety. Safety controls are integral in ensuring that various operational parameters are monitored effectively. This proactive approach minimizes the risk of malfunctions and potential accidents, significantly improving the overall safety of the escalator. Advanced braking systems provide additional reliability by allowing for quicker and more efficient stopping capabilities in emergencies, ensuring that escalators operate within safety regulations and can respond effectively in potentially hazardous situations.

In contrast, painting the escalator brighter colors may improve visibility but does not directly address safety mechanisms or operational functionality. Increasing the number of steps or reducing the escalator's length may alter physical dimensions but does not enhance the safety features that protect users. Thus, upgrading safety controls and implementing advanced braking systems stands out as the most effective measure for safety retrofits.
