What is used to secure a ladder when not in use?

A chock is a device that is specifically designed to secure a ladder when it is not in use. When a ladder is chocked, it is prevented from sliding or falling over, which enhances safety for firefighters and the public alike when the ladder is temporarily stored or left unattended. Chocks can be made of various materials and come in different designs to fit the needs of different types of ladders, providing stability and ensuring that the ladder stays in a vertical position.

While guard, tie-down, and lock may be related to securing various equipment or ensuring safety, they do not specifically serve the same purpose as a chock when it comes to ladders. A guard may refer to a safety feature that helps to protect individuals from hazards, a tie-down is typically used to secure equipment to prevent movement, and a lock is more about immobilizing a tool or device to prevent unauthorized use. Chocks, however, play an essential and dedicated role in the safe storage of ladders.
