Halligan Bar

A Halligan bar (also known as a Halligan tool or Hooligan tool) is a forcible entry tool used by firefighters.

History

The Halligan bar was designed by New York City Fire Department (FDNY) First Deputy Chief Hugh Halligan in 1948 and was named after him. That same year, blacksmith Peter Clarke made the first prototype of the tool. Despite its popularity among FDNY ladder companies, the department initially refrained from purchasing the tool to avoid the appearance of a conflict of interest.''Fire Department City of New York: The Bravest; An Illustrated History 1865-2002'', page 72. However, the Boston Fire Department was the first major customer of the Halligan bar, purchasing one for every fire company in the city. This led to widespread adoption of the tool, first in North America and eventually worldwide. The Halligan bar has become the most versatile hand tool for fireground tasks over the past seven decades.

Design

Based on the earlier Kelly tool, the Halligan is a multipurpose tool for prying, twisting, punching, or striking. It consists of a claw (or fork), a blade (wedge or adze), and a tapered pick, which is especially useful in quickly breaching many types of locked doors.

One variant of the Halligan has a heavy sliding collar on the shaft. Once the prying end of the tool is wedged into position, the sliding "hammer" is used to force the wedge, allowing for proper seating before prying. The adze end is also assisted by using the sliding hammer to generate forced traction on a hooked cylinder. Another variant has an end that resembles a lever-type can opener, used for making large holes for access or ventilation in sheet metal.

The Halligan is available in a number of lengths — typically  — and of various materials, including titanium, beryllium copper or stainless steel. Carrying straps or rings can be found. The 18-inch Halligan is often referred to as an officer's tool.

A Halligan bar and a flathead axe can be joined (and partially interlocked, head-to-toe) to form what is known as a ''married set'', ''set of irons'' or simply ''the irons''. This combination of tools is most common within the fire service. However, the Halligan may also be combined with a Halligan hook or sledgehammer as an alternative.

Uses

* Doors and locks
** Either the adze end or fork end of the tool can be used to break through the latch of a swinging door by forcing the tool between the door and door jamb and prying the two apart, striking it with a sledgehammer or a flat-head axe.
** The firefighter holding the Halligan can use a "baseball bat swing" to sink the pick into the door frame near the door handle and then force the door by applying pressure to the adze.White, Billy & Johnson, Fergus. ''The Backup Firefighter's Role in the Initial Fire Attack''. Fire Engineering. 2011.
** Another option is to use the Halligan to pry the door off the top hinges. The pick and adze (only when properly used) provide protection to the arms, hands, and body of the holder during forcible entry operation.
** The pick can be placed into the shackle (or eye) of a padlock or hasp and twisted or pried to break it free.
** Using a K-tool and the adze end, a lock cylinder can easily be pulled.
* Vehicles
** The Halligan can be used to make a purchase point on a car hood to cut the battery.
** The Halligan can also be used for vehicle extrication, among other things.
** The tool can be used to pry open the hood of a car when it is jammed from an accident.
* The Halligan can be used to knock down a wall in a house to get to another area.
* The point can be used to break glass on a car or building for access or ventilation.
* It can also be driven into a roof to provide a foothold for firefighters engaged in vertical ventilation.
* The fork end is routinely used to shut off gas meter valves.
* The Halligan can be used as a step to get up on a window that is at head level.
* The Halligan can be tied to a rope and act as an anchor in the window frame, for improvised bailout.Thomas Delmar Learning. The Firefighter's Handbook. Thomas and Delmar Learning. Clifton Park, New York. 2000.
