  • Ensure that all individuals are thoroughly trained and familiarized with the intended purpose, correct use and function, and serviceability of the equipment.
  • Ensure that the equipment is properly maintained, inspected, and ready for use at all times.

The TRITON harnesses are LSC’s second generation helicopter-hoistable rescue harness. The 497 Model is standard equipment for the USCG Helicopter Rescue Swimmers and Canadian SAR Techs.

The 490 TRITON II MOLLE version is likewise used around the world by helicopter rescue crews, and is the best swimming harness in helicopter rescue.

Building on the foundation and comfort of the TRI-SAR (#487), the TRITON offers numerous enhancements. When attached, its low-profile flotation vest provides variable buoyancy up to 35 lbs in a sleek, field-packable design. Several equipment pockets have been transferred to the waist belt for improved weight distribution and comfort. Quick release buckles on the leg straps allow for easier donning and doffing of the harness, and a chest strap ensures a better fit. The recovery/equipment hook (when installed)is LSC’s Titanium Talon IIS safety hook with swivel and locking gate.

Constructed of Mil-Spec webbing and low profile, quick adjusting, stainless steel and titanium hardware, all components and materials are corrosion resistant for the marine environment.. The positioning of the hoist strap allows total use of operator hands. Ideal for rapid deployment in a multitude of rescue scenarios. Wide leg and waist straps optimally distribute weight for superior comfort and support.

The Triton Harness/Vest Modular Construction allows components to be removed and replaced.  The following link provides installation procedures for the Triton Vest, and installation of MOLLE pouches. The MOLLE and non-MOLLE vest install identically on the Triton Harness.

There are no required or authorized modifications for the 490-497 Triton Vest-Harness.

  • Rescue harnesses and load bearing webbing products manufactured by LSC for use in Human External Cargo (HEC) operations have a recommended service life limit of fifteen (15) years from Date of Manufacture or twelve (12) years from the date placed in service—whichever shall occur first. The date of manufacturer can be found on the label.

The maximum weight limit for this harness is 450 pounds. The maximum operating weight is the total weight of the individual and all equipment or rescue personnel supported by the harness in an operation. The Talon hook shall be used to carry equipment or tools used to support the rescue function or mission. The weight of the equipment supported by the talon hook shall not exceed the maximum weight limit of 450 pounds.

Proper harness sizing is based on height as follows:

    • PART#-HM (Medium) fits those who are 64”–69” tall (162-175 cm)
    • PART#-HL (Large) fits those who are 68”–73” tall (173-185 cm)

    • PART#-HXXL (Double Extra-Large) fits those who are 74”–80” tall (188-203 cm)

NOTE: This Rescue Harness does not have any unique aspects of installation for the user.

Do not expose the harness to flame or high temperature. Carry the harness where it will be protected as the harness could melt or burn and fail if exposed to flame or high temperature.

Keep these instructions/manual – after it is separated from the harness – and retain it as a permanent record. A copy of these instructions should be kept with the harness.

Refer to these instructions/information before and after each use.

Required Tools, Expendables, and Consumables

Tools / Test Equipment Required

  • Phillips Screwdriver
  • Socket Wrench Set or Crescent Wrench

Expendables Required

  • Paper towels or lint-free towels
  • Emery cloth

Consumables Required

  • Corrosion Preventative Fluid Film

Step 1: Remove all survival equipment contained in any attached pockets. Remove any lanyards tied to the equipment and pocket attachment loops. For MOLLE harnesses, completely remove any attached pockets from the PALS system and Flotation Collar/Vest if installed.

Step 2: If vest is attached – remove vest by removing the three attachment screws and nylon lock-nuts. (LSC Part# H089.)Discard nylon lock-nuts.

Note:

Attaching screws may be re-used. Nylon lock-nuts should be replaced when re-attaching the Flotation Collar/Vest to the harness.

Step 3: Inspect the harness webbing for cuts, excessive wear, loose or broken stitches, and damaged hook and pile tape.

Step 4: Inspect all pockets for cuts, excessive wear, loose or broken stitches, and damaged hook and pile tape.

Step 5: Inspect the load-bearing stitches for any broken or cut stitches. If two or more consecutive loose or broken stitches are found in any single load-bearing stitch pattern, the harness should be sent to an LSC authorized repair center for maintenance.

Step 6: Inspect the security of the bladder attachment tabs.

Step:7 Inspect all stainless steel hardware for proper function and corrosion. Remove any surface corrosion with emery cloth. Check both spring-loaded buttons of each buckle to ensure that they operate and return to home position. Check that a buckle does not open with the depressing of only one button. Check both buttons of each buckle separately to ensure that the buckle tang does not pull out with moderate tension applied. This function check is designed to ensure that the buckles will function as these are a major load bearing part of the harness.

Step 8: Inspect the TALON Hook (if attached) for proper lash and locking function. Inspect the rivets for security of attachment. Inspect for the presence of the roll pin. (See Video Below)

WARNING:

Avoid eye and skin contact with corrosion preventive, fluid film. Avoid inhalation or ingestion. Use in a well-ventilated area. Wash thoroughly with soap and water after handling or exposure. Remove contaminated clothing immediately.

Step 9: Apply a light coat of corrosion preventative fluid film to:

    1. All stainless steel bayonet fittings and buckles
    2. The TALON (or other) equipment hook below the main lifting V-Ring

Step 10: Wipe off excess oil with lint free cloth or paper towel.

Step 11: Reinstall equipment in pockets and – if using a MOLLE Harness – re-attach associated MOLLE pockets to harness.

Step 12: Sign off annual inspection of harness in accordance with local procedures.

Step 13: See Flotation Collar/Vest Instructions for how to re-attach new or ready for issue unit.

WARNING:

Do not use harness if any discrepancies are found.

Inspection of the inflatable vest (490-VOT or 497-VOT) on all TSO Approved TRITON’s shall be done in accordance with the procedures linked below.
