The force necessary to prevent the closing of the car door shall not exceed what weight?

The correct weight that represents the maximum force necessary to prevent the closing of the car door is 30 lbs. This standard is put in place to ensure safety and compliance with regulations that prevent injury or entrapment. The limit is established to ensure that passengers can easily and safely push against the door if necessary, such as in situations where a person may be approaching the door as it is closing, thereby reducing the risk of accidental injury. Setting this threshold at 30 lbs strikes a balance between allowing the door to close securely and ensuring that it is not too heavy for an average person to stop if needed. Compliance with this limit is crucial for the safe operation of elevators and helps promote safety standards in the elevator industry.
