What action must be taken with the assist handle when opening doors in emergency mode?

When opening doors in emergency mode, it is crucial to grab the assist handle securely. This action provides the individual with better control and leverage when operating the door during an emergency situation, where conditions might be chaotic or require speed. The assist handle is specifically designed to help ensure safe and effective operation of the door, allowing for a more stable grip as the door is opened, which can be especially important if the door is heavy or if there are other factors affecting the opening mechanism.

Grabbing the assist handle securely is essential for maintaining safety and minimizing the risk of injury, as well as ensuring that the door is opened correctly to facilitate an efficient evacuation if necessary.
