This halligan bar is a common sight among firefighters when performing their duty. This is because they are multi-purpose tools that allow for different types of rescues, ventilation, and fire suppression. Halligan bars come in different types, as discussed below.
The original Halligan tool was designed by the late Fire Chief Hugh Halligan. This tool is meant to improve door entry for firefighters. The tool consists of a pry bar featuring a forked end, a pick or spear at the other end, and a(c) shaped claw with a serrated edge (the fork) that’s intended to pry doors.
The pry bar is a more simplified version of the Halligan tool. It lacks the spearing end but is ideal for prying open doors, windows, and other structures. It's mainly used when the picking function is of no necessity.
This bar tool is a flat version of the Halligan tool. They are mainly used to open locks or other mechanisms in a horizontal manner. They are used where old, flat springs or flat screws need to be removed. While not exactly like the Halligan, they serve a similar locking function.
This tool closely resembles the forked end of the Halligan. It is best applied when prying apart items and structures. Its forked end is quite beneficial in providing leverage to open doors, windows, and other structures.
As previously discussed, a Halligan bar is a firefighting tool with multiple functionalities. Consisting of a dozen or so features, the Halligan bar needs to be as functional as it is durable. When it comes to firefighting tools, durability is key.The Halligan bars are made using tough and durable material. The most common material for manufacturing the Halligan bar is stainless steel alloy. The alloy contains carbon steel, which makes it highly resistant to corrosion and oxidation. Other materials include Aluminum and bronze alloys.
Carbon steel alloy used for making the Halligan bars is a very hard material. When heated to a specific temperature, the Halligan tool's carbon steel molecular structure is manipulated to make it tougher and more durable. This process is known as tempering. The Halligan bars are then coated with an anti-corrosion coating for further protection.
The hardness of the steel alloy contributes to its ability to hold and maintain sharp edges for longer duration. The sharp edge allows for better prying action. It also adds to its wear resistance, which comes in handy when used in a firefighting environment.
Stainless steel is highly resistant to rust and corrosion. This property allows the Halligan bars to withstand the adverse effects of moisture, chemicals, and pollutants. Stainless steel requires less maintenance than its carbon counterpart. While less hard than carbon steel, it is highly flexible and more shock resistant. Add to it the non-corrosive nature of stainless steel, and it makes for an ideal material for the Halligan tool in marine or humid environments.
Aluminium is lightweight, corrosion-resistant, and an alloy of mixed metals ensures strength and rigidity. It provides an easily maneuverable Halligan bar with minimal fatigue over long use to its user. While not as hard or wear-resistant as the above, an aluminium Halligan is suitable for lighter firefighting tasks and rescue operations.
Choosing the right Halligan bar is crucial when working in the firefighting industry. A Halligan tool should be durable enough to survive the abuse of a Volatile firefighting environment. It should be functional enough to serve its purpose, and its size should be manageable and easy, if not, less straining to handle.Here are a few selection tips to consider when choosing a Halligan bar:
Material Composition
The composition of the materials should be durable and tough enough to withstand irate fires. Ideally, a Halligan bar should be made from carbon or stainless steel. Carbon steel is tougher and provides abrasion resistance, while stainless steel is highly resistant to corrosion, making it suitable for use in marine or humid environments.
Temperature Treatment
A properly manufactured Halligan tool must undergo tempering. This process allocates the steel with better resilience and a sharp edge retention capability. When coupled with the anti-corrosion coating, the tool will be doubly protected from corrosion and wear.
Maintenance Consistency
A Halligan tool made from stainless requires less care compared to that of carbon steel due to the latter's propensity to rust. If the Halligan is made from carbon steel, it should be coated with anti-corrosive substances. While the coating cannot substitute for the maintenance required of the tool, it will minimize the need for care.
Functionality
Consider the various features incorporated into the Halligan tool. The fork has a functional prying bar, while the pick end is fully accessible for piercing or extracting. A functional tool will have a well-sharpened pry, pick, and claws for their applications.
Size
Size is another factor to consider when purchasing the halligan firefighting tool. Halligan tools are typically 30-36 inches long. While the length provides sufficient leverage, it might add to the weight, making it more difficult to handle. Choosing a compact-sized Halligan bar can be easy to handle, especially in tight spots, while a full-sized Halligan can prove useful in open spaces.
Grip
The halligan tools come with rubberized grip for a better hold on the tool even in a slippery situation. This goes a long way in improving the tool's handling and control.
The Halligan tool has firefighting applications. It is used to pry open doors, windows, other structures, and improve fire and rescue operations. Its multi-functional features make it effective in various operations. Here are spaces where the Halligan tool is applied:
Ventilation
Firefighters make openings in roofs, floors, and walls using the Halligan tool during ventilation. This helps smoke and heat escape while allowing fresh air into the structure. Proper ventilation is necessary to improve the affected building's survival chances and reduce fire spread. Halligan tools are used to pry off roof covering materials, ventilate through the roof, and remove window sashes.
Rescue Operations
Rescuers use the Halligan tool to open locked vehicles and other confined spaces to rescue victims trapped inside or who have suffered an accident.Along with the rescues, the Halligan tool can also be used to stabilize or displace any object posing an immediate threat to the life of the victim or the rescuer himself.
Salvage Operations
The Halligan tool comes in handy in salvaging operations where firefighters try to save inventory, equipment, etc., from burning buildings. By leveraging its prying mechanism, the tool helps create openings through which valuable items can be pulled out safely. With its pick, they can pierce through piles of debris, making it easy to salvage necessary business property before it is astray to fire.The Halligan tool can help dismantle and remove items that might fall and further compromise the fire structures stability.
Pre-emptive Firefighting
Halligan tools apply when firefighters map and mitigate potential fire hazards before they occur. By reducing fire risk in high-risk areas, they can help improve public safety and reduce loss of life or property. The Halligan tool can ventilate through windows and roofs and improve airflow and fire spread. The tool can also help eliminate fire hazards by removing combustible materials or structures contributing to fire growth.
Creating Egress
Once the tool pierces through two inches of calibrated foam insulation and misses the fire, it makes a crucial egress by helping firefighters create an opening to exit the building. This maintains their own safety during firefighting operations.
A1: The Halligan tool is an indispensable piece of equipment for firefighters. It was invented by Hugh Halligan to help them force entry into locked doors or other structures while performing their life-saving work.
A2: A Halligan bar crafted from stainless steel will not corrode. If it is made of carbon steel, it will corrode if no maintenance is undertaken. Carbon steel bars are coated with anti-corrosive coating to minimize the potential of rusting.
A3: The Halligan tool is specifically designed and primarily used for firefighting and rescue operations. Its versatility and prying and piercing features make it suitable for other applications outside the firefighting industry. For instance, it can be applied in construction, military applications, and mechanical workshops.
A4: The Halligan bar is built to last. However, it is not indestructible. It can bend, break, or nick if abused or subjected to extreme conditions. Proper care and avoiding misuse will extend the lifespan of the tool.
A5: The Halligan tool's length is typically between 30 to 36 inches. The forked end uniformly measures 1 inch width and 5/8 inches thickness, while the pick or claw end is around 2 inches long and 5/16 inches thick. This makes the tool proportionate to handle effectively during forcible entry.
