Quick Overview

The R&B Fabrications Water Can Carrier Model 200 is a shoulder-slung webbing harness that converts a standard 2.5-gallon pressurized water extinguisher into a hands-free tool, enabling structural firefighters to maintain immediate fire suppression capability during primary search, high-rise operations, and overhaul.

The Model 200 carrier is built around 2-inch high-strength webbing that supports the full weight of a charged extinguisher at approximately 30 pounds, distributing that load across the operator's torso rather than a single hand. The cylinder harness and locking web straps form a retention cradle that prevents slippage during crawling, dynamic movement, or inversion. When properly rigged and worn cross-body, the extinguisher rides at the hip or rear, keeping the operator's hands free for victim search, tool operation, and navigation in limited-visibility environments.

Pre-deployment readiness is non-negotiable. The carrier requires a visual and tactile inspection at the start of every shift, covering webbing integrity, stitching at high-stress junctions, hardware function, and contamination from flammable or corrosive materials. Post-incident decontamination protocol requires hand removal of debris, mild soap-and-water cleaning with thorough rinsing, and complete air drying before the carrier returns to service. High heat and machine drying degrade nylon webbing and must be avoided.

The Model 200 is authorized exclusively for standard 2.5-gallon pressurized water extinguishers from manufacturers such as Amerex, Badger, and Ansul. Use with CO2, dry chemical, or off-spec cylinders is prohibited and risks equipment failure. Any webbing cut or burn exceeding 10 percent of strap width, cracked hardware, separated stitching, or heat-stiffened material requires immediate removal from service.

Field Application Steps

1. PRE-SHIFT INSPECTION: Examine the entire webbing body and shoulder strap for cuts, burns, melted spots, abrasion, and UV discoloration. Inspect all stitched seams for pulled threads or separation, focusing on high-stress junctions, and check all buckles, slides, and adjusters for cracks, deformation, or impaired function.

2. CONFIRM CONTAMINATION-FREE STATUS: Verify the carrier is free of flammable or corrosive contaminants including oil, fuel, and hydraulic fluid before rigging. A contaminated carrier is not cleared for operational use.

3. SEAT THE EXTINGUISHER IN THE HARNESS: Slide the base of the 2.5-gallon pressurized water extinguisher into the bottom of the webbing cylinder harness. Confirm the cylinder is fully seated before proceeding to strap retention.

4. SECURE THE RETENTION STRAPS: Route the locking web strap or straps around the cylinder body, pull tight, and engage each buckle fully. Confirm positive buckle lock by attempting to release with a firm tug.

5. SHAKE TEST FOR ZERO SLIPPAGE: Vigorously shake the rigged extinguisher in multiple directions. The cylinder must exhibit no significant vertical or horizontal play. Re-tighten all straps if any movement is detected.

6. DON TURNOUT GEAR AND SCBA FIRST: Full personal protective equipment, including SCBA, must be donned before slinging the carrier. The strap length must be adjusted to achieve a proper fit over turnout gear, not street clothes.

7. SLING THE CARRIER CROSS-BODY: Place the shoulder strap over one shoulder, for example the right shoulder, so the extinguisher rides on the opposite hip or slightly behind it. The cross-body configuration provides maximum stability and keeps the cylinder clear of the legs.

8. ADJUST STRAP FOR OPERATIONAL POSITION: Set the strap length so the extinguisher sits at or slightly behind the hip with a stable center of gravity. The nozzle and operating handle must be readily accessible, and the hose must be tucked to prevent snagging.

9. ANNOUNCE DEPLOYMENT INTENT: Before drawing the extinguisher for use, identify the target and communicate your intention to deploy to your team. Situational awareness on the fireground requires that crew members know when a suppression action is initiating.

10. STABILIZE AND DEPLOY: Use your non-dominant hand to stabilize the cylinder against your body. With your dominant hand, pull the safety pin, grasp the operating lever, direct the nozzle at the base of the fire, and squeeze the lever to discharge. The slung position allows effective operation from kneeling or crawling posture.

11. POST-INCIDENT DECONTAMINATION: Remove heavy debris by hand, then scrub the carrier with a brush using mild soap and water and rinse thoroughly. Air dry the carrier completely before returning it to service. Do not machine dry or expose to high heat, as this degrades nylon webbing.

12. POST-CLEANING INSPECTION: After decontamination, perform a full inspection of webbing, stitching, hardware, and contamination status as outlined in the pre-shift protocol. Soot and debris can mask damage that becomes visible only after cleaning.
