What is PD door ?

A PD Sliding door, also known as a panic device door or an exit device door, is a type of door that is designed to provide a quick and easy means of exit during an emergency situation, such as a fire or other building evacuation.

PD doors typically consist of a push bar that extends across the width of the door and is connected to a latch mechanism. When someone pushes on the bar, the latch is released and the door can be easily pushed open without the need for a key or other type of access control.

PD doors are commonly found in commercial and public buildings, such as schools, hospitals, and office buildings, where a large number of people may need to evacuate quickly in the event of an emergency. They are designed to meet specific safety standards and building codes and are often required by law in certain types of buildings.

It's important to note that PD doors are not meant to be used as regular entry or exit points, as they do not provide the same level of security as traditional doors with locks and keys. They are intended solely for emergency use and should be kept clear and free of obstructions at all times to ensure that they can be easily accessed when needed.

What are some common types of obstructions that can prevent PD doors from being easily accessed?

There are several common types of obstructions that can prevent PD doors from being easily accessed during an emergency situation. These include:

Furniture and equipment: Furniture such as desks, chairs, and filing cabinets, as well as other equipment such as printers and copiers, can obstruct the path to a PD door and make it difficult or impossible to access in an emergency.

Debris and clutter: Debris and clutter such as boxes, papers, and other materials can accumulate near a PD door and make it difficult to open or obstruct the path to the door.

Signage and decorations: Signs, decorations, and other items mounted on or near a PD door can obstruct the path to the door or make it difficult to identify the door in an emergency.

Snow and ice: In areas with cold climates, snow and ice can accumulate near the PD door and make it difficult to open or obstruct the path to the door.

People: In crowded areas, people can inadvertently block the path to a PD door during an emergency, making it difficult for others to access the door and exit the building.

It's important to keep the area around PD doors clear and free of obstructions at all times to ensure that they can be easily accessed in an emergency situation. Regular inspections and maintenance can help to identify and remove any potential obstructions and ensure that the PD door is functioning properly.
