Halligan bar

1

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. 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 18-54 inch – 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.
