FIELD OF APPLICATION

The Duck-R has been tested in the UK by SGS to the requirements of EN 12841:2006 Type A - Rope Adjustment Device, using Teufelberger 11mm and Edelrid 10.5mm EN1891 Type A Low Stretch Ropes. Other ropes have provided excellent results – check all different ropes prior to use. To be used in conjunction with EN 12841 Type C or B device, each device attached to independent ropes. Each attached to independent anchors with minimum strength of 15kN. Terms: 'Back-Up Rope' is used to describe the 'Safety Line' as termed in EN 12841 2006. 'User' refers to individuals or persons selecting this device for use.

Harness: Front attachment point of an EN361 2002 or EN813 2008 harness. Lanyard: It is recommend that this Duck-R is used with a EN lanyards up to

60cm long. Cows-tail connection may be made using a dynamic climbing rope with suitable terminations, attached to either ventral (waist) or sternal (chest) points. Recommended length: waist <80cm, chest <50cm including any

knots and connectors. Further information provided overleaf.

Connectors: EN 362 2004 Connector - Locking karabiner. Gloves: the use of suitable work gloves is recommended.

IMPORTANT - Keep Cam Spring Lubricated. See section. 16

The Duck is a non-aggressive device and during correct operational use it will not damage ropes. In emergency deployment (see 'Deployment' section) with the exception of very minor glazing a properly used Duck-R will lock on to the Back-Up rope without causing serious damage to itself, its lanyard, karabiners or to the Back-Up rope. The user is responsible for ensuring the combination of all components in the rope access system do not adversely affect the performance of any item with due regard to all user instructions.

DEPLOYMENT

The body of the Duck-R must NOT be squeezed or the Cord pulled to de-weight a loaded or partially loaded Duck-R.

Accidental Deployment

It is essential that all users are competent in the techniques required to overcome accidental loading. If accidental loading occurs during ascent, first check the ascent equipment, then continue ascending until the Duck-R is no longer under any loading. If loading occurs during descent, first check the descent equipment, then use techniques to complete a short ascent of the Working Rope until the Duck- R is no longer under any loading. Any other accidental loading should be assessed and appropriate methods used to overcome the loading. At all times two safety systems must be in place.

Emergency Deployment

If failure of the Working system e.g. Working Rope failure or user detachment from the Working Rope, occurs and the user becomes suspended on the Back-up Rope, the user and work colleagues must consider the planned procedural options available with regard to all factors of the actual event. These options may include amongst others:

I. The deployment and use of a new Working Rope; II. The rescue by a colleague using new ropes; III. The use of the Back-up Rope to attach escape

equipment (descender or ascenders) for the user to evacuate on the single Back-up Rope; IV. Other techniques undertaken by competent persons.

All emergency actions should only be carried out following a risk assessment of the situation. During emergency deployment of the Back-up system any downward movement of the user will be determined by several factors: back-up rope stretch, cows-tail stretch, knot tightening and device slippage. With the exception of very minor glazing a properly used Duck-R will lock on to the Back-Up Rope without causing any damage to itself, lanyard, karabiners or the Back-Up R ope. Followi ng any Eme rgency Deployment all equipment must be removed from service for inspection by a competent person.

WARNING

POSITIONING

At all times that the user is stationary the Duck-R should be positioned as high as possible. The Duck-R must always be above the descender or chest ascender and never below its lanyard/cows-tail attachment point (FF1)

Ascent

To move the Duck-R up the rope, hold the lanyard or karabinerdo not hold the device.

Descent:

The Duck-R backup device is fitted with a Positioning cord. Users must always perform full function checks of both their descent device and Duck-R before each descent. To move the Duck-R down, pull the Positioning cord down using the index finger and thumb. Users should only hold the positioning cord for as short a period as necessary and ensure that they are prepared to let go of the Positioning cord immediately at all times.

In many applications the Duck-R should be controlled independently of the descent device, in others it may be necessary to control both Duck-R and descent device simultaneously. It is the responsibility of the user to carry out a risk assessment and determine which method is best for their operational activity and environment.

NO!

DOW

WARNING

If users keep hold of Positioning Cord the device will not function. Users must release their hold of the Cord immediately if anything unexpected occurs. At all times check the lanyard is not caught on obstacles and that it will not come in to contact with sharp edges, heat, tools or any other source of damage.

GENERAL INFORMATION

Rope Condition: wear, wetness and contaminants will affect

the performance of the Duck-R. Some rope conditions will make positioning of the Duck-R more difficult. Others e.g. oil & grease will affect the device’s ability to perform - Back-Up may not be provided. The effective operation of the Duck-R should be monitored and checked in all conditions. Where any performance doubt exists, the Duck-R should not be used. Sea Water: it is essential that this Duck-R is cleaned as soon as practicable after each exposure to sea water or saline environment. Chemical reagent: avoid contact with any substance or material that may causes corrosion or other damage to the device.If contact occurs consult expert advice as to damage and cleaning requirements. Inspect prior to any re-use. Maintenance: the Duck-R is not user maintainable with the exception of disinfection, cleaning and lubrication as detailed below. Disinfection: following any contamination the source of the contamination should be determined and advice obtained as to suitable disinfecting procedure. After disinfection the device should be re-cleaned. Sterilisation may be required. Cleaning: If soiled rinse in clean warm water of domestic supply quality (maximum temperature 40°C) with mild detergent at appropriate dilution (pH range 5.5 - 8.5). Dry naturally away from direct heat sources. To remove grease use a detergent that has properties that do not affect the metal spring, body, cam or nylon cord.

Lubrication: It is essential to maintain lubrication of the Cam spring. Lubricate regularly and after cleaning with light machine oil or teflon or silicone lubricant to ensue free movement of the cam. Wipe off the excess to avoid contamination of ropes and textile equip.

Lifespan: it is very difficult to define the safe lifespan due to varying use and storage conditions and may be as little as one use, or even earlier if damaged (e.g. in transit or storage) prior to first use. For the product to remain in service it must pass a visual and tactile examination. Maximum lifespan: 10 years from 1st use. Maximum Cam wear 1.5mm. Obsolescence: this device may become obsolete before the end of its lifespan. Reasons for this may include changes in applicable standards, regulations, legislation, development of new techniques, incompatibility with other equipment etc. Transportation & Storage: after cleaning store unpacked in a cool, dry, dark place in a chemically neutral environment away from excessive heat or heat sources, high humidity, sharp edges, corrosives or other possible causes of damage.

Do not store wet.

WIND & OBSTACLES

Duck-R

EVO

Wind

The effect of Wind can create additional slack rope above the Duck-R, this must be managed at all times. It may be necessary to add friction to the Back-Up Rope below the Duck-R or pull rope through at work zones to partially load the device.

Rope Obstacles

Great care is required if there are any devices, knots or othe r obstacles attached to the Back-Up Rope within 3m be l ow th e D u ck -R . I n t he se circumstances the Duck-R must be kept as high as possible with less than 10cm of slack in the lanyard or cows-tail until the obstacle is dealt with.

ATTENTION TO WIND SPEED.

R R R

1. Push the cam through the device body to the opposite side and attach the lanyard karabiner; this helps to prevent dropping the device.

2. Attach the device on to the rope with the 'Arrow' pointing in the direction of the rope´s anchor.

3. Remove the lanyard karabiner and allow the cam to return through the device body.

4. Attach the lanyard karabiner to the connection point, check that the karabiner gate is fully closed and locked.

STAGES OF INSTALLATION

Move the device along the rope and check that it stays in position, then with one hand holding the lanyard or cows-tail, pull down vigorously to verify that the device locks on to the rope.

To maintain good spring action ensure that cam spring is lubricated regularly. See section 16.

CLEARANCE DISTANCE

Ad dit io nal ly un con tr oll ed do wn war d movement will occur due to the elongation of the Back-Up Rope during loading. This should be assessed for the particular rope being used but a minimum of 10% elongation should be expected.

The amount of elongation will depend on several factors including: I. Elongation Properties of the particular rope used; II. Length of rope between the Duck-R and the rope anchorage; III. Knot tightening; IV. Weight of user; V. Amount of slack in cows-tails/lanyards; VI. All other factors that must be determined by the user;

On long ropes the elongation will be many meters. Clearance – The clearance distance must be carefully assessed for all situations. At work positions when th e device i s positioned high and there is less than 10cm slack in the Lanyard or Cows-tail there will be very little slippage (e.g. a 100kg user less than 20cm). Additional slackness in the connecting lanyard increase slippage.

On-Rope Rescue:

Rescues should be planned and generally designed to limit the exposure of rescue team members. On-Rope Rescue should only be undertaken if the casualty is in urgent need of medical attention that requires evacuation. Additional training and competence is required for all persons performing rescues.

During all On-Rope Rescues the Duck-R must be kept above the shoulder height of both the rescuer and casualty. Where practicable Safe Tec recommend that one Duck-R be used for each person, each on its own rope and each controlled independently of the descent device.

Rescue ropes must be suitably anchored and free from sources of damage. Users must consider all factors affecting Duck-R performance including obstacles, additional rope elongation and increase clearance requirements as well as all other sections in the user manual.

FURTHER INFORMATION

Lanyard – Cows-tail Length

Safe Tec acknowledge that the Duck-R has successfully passed the EN12481A – FF2 test with a 1m dynamic rope cows-tail, but do not advise or recommend its use in FF2 situations.

Recommended length: waist <80cm, chest <50cm including any knots and connectors.

FF1 tests with a 1m cows-tails produce lower impact forces and less slippage-well below the m ax im um a cc ep t a b l e i n E N 1 2 8 4 1 A requirements. Safe Tec would recommend that with 1m cows-tail the FF should be kept below Ff1.

The use of Lanyards/Cows-tails of lengths or material different to those recommended in the User Manual, should assess for the manner of intended use and all users competent to control the position of the device allowing for any increase (or decrease) in length with due regard to the function of the Duck-R.

All users must be are aware of and paying

attention to all factors associated with risks associated with slack in the lanyard, rope elongation/stretch, clearance, entanglement or other factors affecting the safety of users and performance of the device.

As recommended in the user manual; users should ensure optimally positioning at all times.

The use of the Duck-R to Anchor one end of a tensioned rope will provide an absorbing system, this will allow the rope to slip in the event of any overloading. Competent and trained persons who choose the Duck-R as part of a planned tension system must ensure that the loadings are within the capabilities of all components of the tension system tensioned ropes greatly increase the load on anchorages, Safe Tec recommend a minimum of 30kN for the combined strength of all anchorages used for tensioned systems. Users must consider all other sections of this manual with special attention to the Positioning Warning and the information detailing Clearance Distance and Rope Stretch considerations and limitations. Safe Tec recommend that two simultaneously loaded tensioned ropes are the preferred choice in all Tension Systems.

Rescue - Hauling & Lowering:.........................................................................................

.........................................

Nothing should affect the proper function of the Duck-R in the event of any emergency loading. During use as a Back-up for a Hauling or Lowering System the Back-up rope must be attended to constantly and no more than 20cm of slack be allowed in the back-up rope, before repositioning the Duck-R. Safe Tec recommend that the Duck-R is controlled by its own attendant so that optimum positioning can be maintained at all times.

Safe Tec recommend that two tensioned (equally loaded) ropes are the prefered choice in all Hauling and Lowering Systems - both ropes being hauled or lowered simultaneously and sharing the load. More than one person maybe required to operate Hauling or Lowering Systems

The Duck-R can be used as part of a planned restraint system of sufficient strength for any potencial loading.

The length of available rope including Duck Lanyard must be shrorter than the distance from its anchorage to any exposed edge or potential fall danger zone.

Where users are required to partially or fully load the system in any danger zone (e.g. to provide support or partial support) a second system must be in place prior to any loading.

Use on a loaded or pre-tensioned rope:

The Duck-R is designed to be used on an unloaded untensioned ropes as required in EN12841. The performance on a rope that has been deliberately tensioned must be verified prior to use. If during a rescue (or rescue training) a casualties ropes are to be used for access to the casualty; the performance of both the rescuers and the casualties back-up and main working systems must be assessed and performance verified prior to sta rting rescue access. Addi tional safety measures will normally be required, including additional training and equipment. For rescue training additional ropes and/or safety attachments is best practice.

Other Users: The Duck-R has been used for applications that are outside the scope of EN 12841A and the CE mark attached to each device. The design of systems, planning and verification of system suitability for the specific intended applications is the responsibility of the user, all anchorages must be suitable for any load. Competence is required for all applications, additional safety measures must be implemented during training exercises, this must include the close supervision by competent instructor. Users must consider all sections of the user manual with special attention to the and the information detailing and Positioning Warning Clearance Distance Rope Stretch considerations and limitations. All installed devices should be independently function checked with suitable back-up in place prior to any rope operations.
