What device must all power-operated doors and gates be equipped with?

All power-operated doors and gates must be equipped with a reopening device to ensure safety. This device plays a crucial role in preventing injuries by automatically reversing the door or gate's movement if it encounters an obstruction while closing. This function helps protect individuals from being trapped or injured by the closing mechanism. Additionally, the reopening device must be able to detect when something is in the path of the closing door or gate, so it can safely halt and reverse its motion.

The inclusion of such devices is critical in the context of elevator operation, where ensuring the safety of passengers is a top priority. Each elevator installation adheres to specific safety codes and regulations that mandate this feature to protect against potential mishaps with power-operated doors. This requirement reflects the industry’s commitment to safe operation practices, reducing the risk of accidents that could arise from door-related issues.
