Maintenance, Cleaning, and Storage

Repairs to SRLs can only be made by an entity authorized by KwiKSafety. If an SRL fails inspection in any way, immediately remove it from service, and contact KwikSafety to inquire about its return or repair.

Cleaning after use is important for maintaining the safety and longevity of SRLs. Remove all dirt, corrosives, and contaminants from SRLs before and after each use. If an SRL cannot be cleaned with plain water, use mild soap and water, then rinse and wipe dry. never clean SRLs with corrosive substances.

When not in use, store equipment where it will not be affected by heat, light, excessive moisture, chemicals, or other degrading elements. Product must be inspection BEFORE EACH USE.

Inspection

KEEP INSTRUCTIONS AVAILABLE FOR REFERENCE. Record Date of First Use.

Prior to EACH use, inspect all SRL components for deficiencies, including, but not limited to, corrosion, deformation, pits, burrs, rough surfaces, sharp edges, cracking, rust, paint buildup, excessive heating, alteration, and missing or illegible labels. IMMEDIATELY remove SRL from service if defects or damage are found.

Prior to EACH use, inspect all screws, nuts and bolts, and connections to ensure that they are securely fastened and in proper working order.

Prior to EACH use, check lifeline retraction by pulling out a minimum 4’ and allowing it to retract under light tension; lifeline must retract completely. Pull lifeline sharply to test braking function; brakes must engage.
Depending on model or configuration, check shock pack for signs of deployment, and/or fall arrest indicator for signs of activation. IMMEDIATELY remove from service if SRL does not function properly, of if any evidence of exposure to forces of fall arrest exists.

Ensure that applicable work area is free of all damage, including, but not limited to, debris, rot, rust, decay, cracking, and hazardous materials. Ensure that selected work area will support the application-specific minimum loads set forth in this instruction manual. Work area MUST be stable.

Every month, a Competent Person other than the user must inspect SRLs. Competent Person inspections MUST be recorded in inspection log in instruction manual and on equipment inspection grid label. The Competent Person must sign their initials in the box corresponding to the month and year the inspection took place.

During inspection, consider all applications and hazards SRLs have been subjected to.

Product Specific Applications

Use of equipment in unintended applications may result in serious injury or death. Maximum 1 attachment per connection point.

Personal Fall Arrest: SRLs may be used in Personal Fall Arrest applications to support a MAXIMUM 1 Personal Fall Arrest System. Structure must withstand loads applied in the directions permitted by the system of at least 5,000 lbs. No vertical free fall is allowed. SRL must always be positioned at or above harness attachment point. Applicable D-ring: Dorsal.

Restraint: SRLs may be used in Restraint applications. Restraint systems prevent workers from reaching the leading edge of a fall hazard. Always account for fully deployed length of SRL. Structure must withstand loads applied in the directions permitted by the system of at least 1,000 lbs. No vertical free fall is permitted. Restraint systems may only be used on surfaces with slopes up to 4/12 (vertical/horizontal). Applicable D-rings: Dorsal, Chest, Side, Shoulder.

*For all applications: worker weight capacity range (including all clothing, tools and equipment) is 130-330 lbs., or up to 420 lbs. if used in combination with equipment explicity certified for such use.**

Limitations

Fall Clearance: There must be sufficient clearance below the anchorage connector to arrest a fall before the user strikes the ground or an obstruction. When calculating fall clearance, account for a MINIMUM 3’ safety factor, deceleration distance, user height, length of lanyard/SRL, and all other applicable factors. Diagram shown is an example fall clearance calculation ONLY.

Anchorage: The anchorage to which the SRL is attached must sustain static loads applied in the directions permitted by the fall arrest system of at least 5,000 lbs. Refer to OSHA and ANSI for specific definition. This device is to only be used by one person. Select a location for anchorage of the SRL that will avoid a free fall and swing fall hazards. To prevent an increased free fall distance, do not work above the anchorage location.

Swing Falls: Prior to installation or use, make considerations for eliminating or minimizing all swing fall hazards. Swing falls occur when the anchor is not directly above the location where a fall occurs. Always work as close to the anchor point as possible. Swing falls significantly increase the likelihood of serious injury or death in the event of a fall.

FALL CLEARANCE CALCULATION

Compatibility: When making connections with Cobra SRLs, eliminate all possibility of roll-out. Roll-out occurs when interference between a hook and the attachment point causes the hook gate to unintentionally open and release. All connections must be selected and deemed compatible with Cobra SRLs by a Competent Person. All connector gates must be self-closing and self-locking, and withstand minimum loads of 3,600 lbs, and all connectors must be capable of supporting at least 5,000 lbs.

See the following for examples of compatible/incompatible connections:

Correct Anchorage Positioning
