Strength Rating Ultimate Strength Capacity: Min. 5,000lb(22.5kN) in any direction the load is applied to the top fixture. Proof Loading: Only part numbers with (W) suffix are rated for proof loading and must not exceed 2,500lb(11.3kN). 4-1 Design Load: 1,250lb(567kg). Anchor Locations: Are determined by the fall protection design and use as single anchor point (PPE), Horizontal Line (HLL) or window washing. Typically specified by the project architect or engineer with spacing of 20-30ft o.c. SAS plan service is available. See pg. 4. Fall Protection Specifications of Use1 person max. user wt. 340lb including tools and equipment.

Horizontal Lifelines (HLL) End anchors or intermediate anchors as shown at pg.4 Fig.4.0. User PPE: Users are required to wear a full body harness (FBH), a personal energy absorber with other fall protection components that comply with current OSHA/ANSI/CSA standards. Window Washing: (W) suffix part numbers are rated for window washing and required to be bolt attached, as shown at Figs. 1.6-1.7, field welded Fig.1.5 or concrete embedment Fig.1.4. Fastener Options: See Table 3.3Screws: Use only for CRA 8", 12" and 18" riser heights. No HLL or window washing use. Fastener specifications shown at Table 3.3 pg.3.Wood Substrates: 40ea No. 2022 SAS supplied Hex screws as shown at Figs. 1.1-1.2-1.3 or HeadLok screws with gimlet point for wood. Metal Decking: Install CRA with a maximum riser height of 18” over 22ga or thicker Type-B metal decking. Attach over the top flute as shown at Fig.1.3 with 36ea SAS supplied No. 2022 hex screws. Fastener penetration shown at Figs 3.3-3.4. For Insulation panels shown at Fig.3.3 use SAS supplied Head-Lok SD tip screws for metal. Note: Riser heights over 18” require to be bolt attached. Project specific engineering is required and use of backer plates as shown at Fig.1.7.Bolt Attachment: Risers over 18" are required to be bolt attached with a min. of 4 each 1/2"d. grade 8 stainless steel or type A307 all thread w/lock nuts see Figs.1.6-1.7. Steel backer plates are required unless the CRA is bolted directly to a structural steel member. See pg. 3 for bolt hole specifications.Concrete Embedment Bolts: Wedge type 1/2"d. to be specified by project architect/engineer and installed per bolt mfg. specifications. Flat washers are required. See Table 3.1 pg. 3.Poured in Place: 1/2"d. J bolts or equivalent specified by architect or engineer.Concrete PSI: 2500lb min. concrete must be sufficiently cured to support the fall protection load. Field Welded: Weld base plates to structural steel members per SAS/field weld specifications shown in Table 3.2. pg.3 and Figs. 3.0 and 3.2. Base plates may be supplied without bolt holes when requested.Welding required to be performed by a certified welder. Wood Framing: Install over structurally engineered wood framing as shown at Figs. 1.1-1.2 and pg. 4 details for substrate and backer specifications. Wood screws must be installed through at least one layer of 3/4" plywood. Structural Steel or Wood Beams: As shown at Figs. 1.6-4.4, use a CRA standard or custom sized anchor and backer plate that allows bolts or A307 rod to be positioned as close as possible to the beam. Structural Support The anchor attachment point must be structurally capable of supporting 5,000lb or 2x the intended fall protection load per OSHA 1910.140(13). 3rd party structural engineering is available from SAS upon request. For example: 1 person w/energy absorber maximum arrest force of 1,800lb x 2= 3,600lb attachment point.

A record of annual inspections by a qualified or competent person should be maintained. SAS inspection points may be used as part of the building owner’s maintenance plan. Warning! Anchors subjected to a free fall or other damage must be tagged to prevent further use until inspected by a qualified or competent person. Inspection points . =Remove From Service. =Repair. Model SpecificationsCRA anchors in Table 1.0 are standard design riser and base plates. Custom fabricated anchors are available. US mfg. CRA’s are supplied in 304 or 316sst. Imported CRA’s are supplied with 304 risers and 430 base plates. The vent hole required for galvanizing is plugged with a 3/8”sst hex screw and thread sealant. The plug is removable for foam filling if necessary. Reapply sealant if the plug is removed. Inspect welds. If cracks present. Rust present. Clean and apply cold zinc coating. PID Label Missing.

Cordaje/Plan de Distancia de CaídaEl plan de distancia de caída se muestra (LOFP, por sus siglas en inglés) debe utilizarse únicamente como guía.

The greater the slack, the wider the range of horizontal movement.Line slack is calculated by subtracting the D-ringheight “B” from the free fall length “A”. C= 20”(0.5m)WARNING! Too much line slack will increase the free fall length. Make adjustments to limit the slack.

Lifeline Working Length is the distance between the anchor point and the leading edge + the line slack. A rope grab is used to fix the workers position on the lifeline and a “termination knot” is used to gauge or limit the free fall length. The excess lifeline below the rope grab or termination knot is surplus line.Rigging Example: Attach lifeline to anchor point “A”. With tension on the line move the rope grab down slope vertically to the leading edge shown at Fig.8.4. From this position, add the line slack “C” calculated in your own LOF plan and tie a “limiter knot” at that point.(overhand or half hitch knot) The rope grab may be positioned at the limiter knot. As you travel along the leading edge away from the vertical position, you will be forced upslope as the line slack is reduced. Fig.8.5 is the max. leading edge travel allowed by anchor “A”. Further travel along the leading edge without lengthening the free fall will require to use anchor “B”. If your JSP and slope angle allows limited duration exposure, disconnect from anchor “A” and move to anchor “B”. 100% tie-off will require to use a second lifeline attached to anchor point “B”. A free fall with line slack will generate a swing fall. Be sure to inspect for obstacle hazards below the leading edge. Lengthening the free fall to more than 6ft(1.8m) is not permitted by OSHA/ANSI or CSA. Job Specific Plan by employer or end user.

A failure to calculate the LOF can result in strikingthe ground or a lower level WARNING: PROMPT RESCUE!A plan for immediate rescue is necessary to avoid serious injury or death resulting from suspension trauma. Request SAS Trauma Strap No. 6060 Distancia al Suelo Insuficiente¡ADVERTENCIA! Un error en el cálculo de LOFpuede ocasionar un golpe contra el suelo o nivel inferior ADVERTENCIA: ¡RESCATE RÁPIDO!Se requiere de un plan de rescate inmediato para evitar lesiones o muerte a raíz de un trauma de suspensión. Solicitar cinturón para traumatismo de SAS No. 6060 Plan de Muestra de Cordaje de Cuerda Salvavidas.Zonas de Servicio de Anclaje: se basan en una caída libre máxima de 6 pies(1.8m) y se determinan como radio o diámetro que se extiende desde un punto de anclaje al borde frontal u otro peligro de caída. La Distancia de Trabajo de la Cuerda Salvavidas corresponde al tramo desde el punto de anclaje y el borde frontal + de la cuerda floja. Se utiliza una polea de tracción para arreglar la posición del trabajador en la cuerda salvavidas. También se utiliza un “nudo de cierre” para medir o limitar la distancia de caída libre. El exceso de cuerda salvavidas por debajo de la polea de tracción o nudo de cierre se considera Cuerda excedente.Ejemplo de Cordaje: Coloque la cuerda salvavidas en el punto de anclaje “A”. Aplicando tensión sobre la Cuerda, mueva la polea de tracción cuesta abajo verticalmente hacia el borde frontal tal como se muestra en la Fig.8.4. Desde esta posición, agregue la cuerda floja “C” calculada en su propio plan LOF y amarre un “nudo limitador” en dicho punto (nudo simple o medio nudo). La polea de tracción debe ubicarse en el nudo limitador. A medida que se desplaza por el borde frontal lejos de la posición vertical, deberá moverse cuesta arriba mientras se reduce la cuerda floja. Fig.8.5 Corresponde al desplazamiento máximo del borde frontal permitido por el ancla “A”. Un desplazamiento superior a lo largo del borde frontal sin la prolongación de la caída libre exigirá el uso de un ancla “B”. Si su JSP y ángulo de cuesta le permiten una exposición de duración limitada, desconecte del ancla “A” y desplace hasta el ancla “B”. Un amarre del 100% requerirá del uso de una segunda cuerda salvavidas conectada al punto de anclaje “B”. Una caída con la cuerda floja provocará una caída con oscilación Asegúrese de revisar obstáculos que representen un peligro para el borde frontal. La expansión de la caída libre por más de 6 pies(1.8m) no está permitida por la OSHA/ANSI o CSA. Plan específico del trabajo por el empleador o usuario final.
