What characterizes an Individual Dogged Door?

An Individual Dogged Door is characterized by its ability to be held open for access. This design feature is particularly useful in scenarios where continuous access is needed without the need to constantly hold the door open manually. The door can be secured in an open position using a dogging mechanism, which typically involves a device that locks the door in place. This makes it easier for firefighters or emergency personnel to move in and out freely, especially in situations where speed and accessibility are crucial.

The other options do not accurately describe the main characteristic of an Individual Dogged Door. For example, while some doors might automatically seal or require special tools to open, these features do not apply to the dogged door’s primary function of allowing easy access. Similarly, a door that only opens with a key would not fit the definition of an Individual Dogged Door, as its purpose is to facilitate quick entry rather than restrict access.
