A quick connect and disconnect coupler (QCDC) having a coupler plug and a coupler socket. The coupler plug has an input that is connected to a fluid source and an output. The coupler socket has an input that is connected to the coupler plug's output, and an output that is connected to a hose from where the fluid is applied to a fire. The coupler socket features a front and rear gripping flange that together allow a person to safely, quickly, and easily attach the coupler socket to the coupler plug. The QCDC also features a safety lock that is normally in a locked position, which prevents the socket from being attached or detached to and from the plug. The safety lock is released from its locked position only after a determination has been made that it is safe to attach or detach the coupler socket from the coupler plug.
