Quick Overview

The R&B Fabrications Iron Sling (IRS-125) is a hands-free tool carry system designed for trained fire-rescue operators to transport a married flathead axe and Halligan bar during structural firefighting, technical rescue, and RIT/FAST operations.

The IRS-125 solves a specific tactical problem: moving forcible entry tools through smoke-filled stairwells, up ladders, and across debris fields without occupying the operator's hands. The system secures a flathead axe and a 30 to 36 inch Halligan bar into a single balanced package worn diagonally across the torso over the SCBA cylinder. This configuration maintains three points of contact on ladders and preserves full situational awareness during approach to an objective. Deployment at the door is a single carabiner release, presenting tools married and ready for immediate use.

The system's three components are engineered for fireground conditions. The adjustable heavy-duty nylon shoulder sling distributes tool weight of 20 or more pounds across the operator's torso and cinches snugly over full turnout gear to minimize shifting during dynamic movement. The all-metal carabiner resists failure in high-heat environments where plastic hardware may become brittle or melt. The removable nylon axe blade sheath protects both the cutting edge and the operator from laceration injury during transport and must be confirmed in place before the tools are slung.

Readiness protocol for the IRS-125 requires inspection at the start of each shift and after every fireground operation. Operators must check the nylon webbing for cuts, frays, chemical contamination, and thermal glazing, with close attention to stitching at stress points. The carabiner gate must be actuated multiple times to confirm smooth function and secure closure. Any component that fails inspection is removed from service immediately and tagged for repair or disposal.

Field Application Steps

1. SHEATH THE AXE: Confirm the nylon blade sheath is fully seated over the axe head, covering the entire cutting edge. The sheath must be in place before any further steps are taken.

2. MARRY THE TOOLS: Place the Halligan bar flat against the axe handle with the adz end nested near the axe head and the fork end positioned near the base of the axe handle. The two tools should sit flush against each other, forming a stable, singular unit.

3. CAPTURE THE TOOL ENDS: Wrap the fixed loop of the sling around the married axe head and Halligan adz. Wrap the carabiner-end loop around the axe handle base and Halligan fork.

4. VERIFY SECUREMENT: Pull on the sling firmly to confirm both loops are seated and secure. The tools must not shift or rotate independently within the sling.

5. CONFIRM CARABINER CLOSURE: Visually and physically verify the carabiner gate is fully closed and locked. Incomplete closure risks accidental release and dropped tools, creating a severe impact hazard to personnel below.

6. DON THE SYSTEM: Place the sling over your head and non-dominant shoulder, running it diagonally across the torso. The tools should lie flat against your back, positioned over the SCBA cylinder.

7. ADJUST FOR FIT: Cinch the adjustment buckle until the tools are held snugly with minimal movement during dynamic actions. An overly loose sling creates a snag hazard in confined or debris-filled environments.

8. EXECUTE RELEASE AT OBJECTIVE: Upon arrival at the objective door, grasp the sling webbing on your chest with your non-dominant hand. Simultaneously pull the sling forward and away from your body while using your dominant hand to unclip the metal carabiner, releasing the entire sling in a single action.

9. PRESENT TOOLS: Let the sling fall away. The tools will be free in your hands, properly married and immediately ready for forcible entry operations.

10. INSPECT AFTER USE: Following every fireground operation, inspect the full length of the nylon webbing for cuts, frays, discoloration, and thermal glazing. Actuate the carabiner gate multiple times and inspect the sheath for punctures, tears, or heat damage. Remove from service immediately if any component fails.
