P15PS00924 – JEFF Repair/Replace Louvers Appendix A – Additional Information

The Structure: The Gateway Arch (Arch) is located on the banks of the Mississippi River in downtown St.

Louis, Missouri as part of the Jefferson National Expansion Memorial. Designed by Eero Saarinen as a catenary curve, its structure is provided by a steel and concrete double wall construction of stainless steel plate at its exterior and mild steel plate at the interior. Concrete fills the void space between the exterior and interior walls of the legs to about the 300 foot level. The Arch is 630 feet tall and 630 feet wide at its base. Its construction was completed in 1968.

Work will encompass safety setup, evaluation of both north and south louver guards, exterior welding on the stainless steel components, and demobilization of the exterior area and safety materials.

It is anticipated to take multiple days for safety setup, inspection and repairs. Please review Safe Practices for Rope Access Work as authored by the Society of Professional Rope Access Technicians.

person at height should be such that it cannot be accidentally removed, dislodged or become unfastened from the rope while a person is suspended from it.

10.3 *Harnesses Harness performance and construction should comply with relevant, nationally recognized standards such as NFPA, UIAA, ANSI, ASTM.

10.4 *Carabiners Carabiners and similar connectors with screw-gates or self-locking methods of closure are the only types that can provide the required level of security for this type of work. If used to clip onto steel cable, shackles or eye bolts, they should be constructed of steel or other suitably hard metals. Those that are to clip to any anchorage (e.g., hanger, eye bolts, or shackles) should be of such a design and size that they can rotate freely in them without hindrance and without loosening the anchorage.

Minimum strength: 22 kN (5,000 lbs).

10.5 *Descenders Descenders should give the user suitable control over the speed of descent and should not cause undue shock loads to the rope when braking.

In addition they should not cause abrasion, plucking or stripping of the sheath under normal or expected use.

They should be of a type that cannot become accidentally detached from the rope.

10.6 *Rope Grabs Rope grabs should be of a type that will not slip at a static load below 2.25 kN (506 lbf). Rope grabs should be of a type that cannot be accidentally detached from the rope. Ascenders should be chosen so as to minimize the risk of damage to the rope when in use.

10.7 Ropes

10.7.1 *Ropes made from nylon or polyester will normally be the most suitable for rope access work. Ropes of other man-made materials might, however, be useful in specific situations. In such cases, great caution should be exercised in verifying their suitability for the work.

10.7.2 *Static or Low Stretch Ropes shall normally be used for ascending and descending on rope. Static or Low Stretch Ropes shall be of a kernmantle construction compliant with Cordage Institute 1801 Low Stretch and Static Kernmantle Life Safety Rope, and have a minimum breaking strength sufficient to supply the users’ desired calculated system safety factor. In no case shall the safety factor for a rope access system be less than 5:1.

10.7.3 Where a fall in excess of a factor .25 fall

might occur, dynamic rope should normally be used in place of static or low stretch rope. Dynamic safety rope should be of a kernmantle construction compliant with UIAA/CE (or comparable) standards for single climbing ropes.

10.8 Webbing.

Webbing used shall have a minimum breaking strength of at least 17.5 kN (4,000 lbs) when new. High modulus fibers such as Spectra, Kevlar, Vectran and similar fibers with minimum elongation may break when subjected to shock loading and shall not be used where a shock load may be applied.

10.9 *Certification.

It is recommended that only equipment that has a current certificate of the safe working load or minimum breaking strength, or other certification as to reliability, should be used. A check should be made that all certificates are backed by either sample testing to failure, or proof testing on individual items, and a proven quality assurance program, in accordance with an appropriate standard. Equipment should be only used in the manner indicated by the manufacturer.

10.10 *Care and Inspection of Equipment

10.10.1 Employer shall demonstrate that all

equipment is used, inspected and maintained in accordance with manufacturer’s instructions. Provisions shall be made for the retirement of equipment as necessary.

should be utilized if the work is such that the Rope Access technician may become overtired or suffer restriction to their blood flow.

13.2 When such platforms are used in

conjunction with rope access methods, the anchorages for the platform should be totally independent from anchors used by Rope Access technicians as main lines or safety lines.

13.3 Alternatively, support could be provided

for the Rope Access technician by a comfort seat or strap incorporated into the harness system. This should be fitted in a manner that it does not detract from the harness being the primary means of safety.

14 TOOLS AND WORK EQUIPMENT

14.1 *All tools and equipment must be suitable for the work intended and compatible with rope access work. In particular, they shall not present a danger to the safe operation or integrity of the rope access system.

14.2 *Where the workers carry tools and equipment, appropriate steps shall be taken to prevent them being dropped or falling.

14.3 *All electrical equipment, plugs, sockets, couplers, leads, etc. should be suitable for the environment in which they will be used.

14.4 Power tools weighing more than 10 kg

should be fitted with a separate suspension system secured to an independent anchorage. Anchorages and suspension ropes used for equipment should be clearly identified to avoid confusion with those used to support persons.

14.5 Moving parts of tools should be kept

clear of the operator, power leads and the suspension equipment.

14.6 Appropriate grounding shall be provided

for as necessary.

14.7 Any power tools that could cause injury

to the users or access equipment shall be fitted with an automatic shut off switch that will interrupt the power and stop movement in the event of a mistake, accident, or emergency.

15 RESCUE AND EMERGENCY

SERVICES

15.1 *The employer shall have a rescue plan for every rope access work site or project. The plan shall provide for the prompt rescue and safe extrication of a sick, injured or entangled worker. The plan shall include the following provisions:

15.1.1 The plan shall ensure that all persons

conducting rope access work have been trained and are competent to perform self rescue.

15.1.2 The plan shall ensure that sufficient

rope access personnel trained and competent in partner rescue are present and available to perform a rescue in a manner appropriate for the mechanism of injury or the patient’s medical condition.

15.1.3 The plan shall ensure that the

supervisor is capable of managing a rescue incident and where appropriate, performing a rescue.

15.1.4 The plan shall include the information

required to respond to the appropriate emergency services.

15.2 Retrieval systems or methods shall be

available on-site whenever a rope access worker is on-rope, unless use of the retrieval equipment would increase the overall risk of the rope access work, or would not contribute to the rescue of the rope access worker.

15.3 Retrieval procedures using retrieval

systems should be practiced at regular intervals and before the start of any work at situations that are unfamiliar to the work team.

APPENDIX

A2.1 The documentation prepared by the employer describing how a particular job or jobs should be undertaken may have different titles such as access work plan, access permit, work plan and tailboard form.

A2.4.2 In general use a deviation anchor should not pull the rope system more than 15 degrees off of the vertical.

A2.6 Ascender-type rope grabs come in a variety of designs. Many of those designs are not appropriate to use as a connection to the safety line or for belaying a worker.

A2.9 A locking carabiner may include the standard screw-gate or other style carabiner in which a positive action is required to lock the gate.

A.2.9.3 May also be called auto-lock, quik-lok or some variation of those terms.

A2.10 Descender usually refers to a device attached to the operator and enables the operator to control the rate of descent down the rope. Many descenders may be attached to an anchor and used to control the rate of descent of a worker or equipment being lowered.

A2.16 The hazard zone is concerned with the risk that the public or other workers may be struck by a falling object. This includes the workers on-rope as well as anyone at ground level.

A2.17 The component of the Access Work

Plan which identifies hazards, the hazard mitigation methods and outlines requirements to promptly rescue the rope access worker may have different titles for different employers, but will contain the basic information. Names often used include job safety analysis, site specific safety plan, hazard analysis, tailboard form and risk assessment.

A2.27 Rope Access Technicians use a variety of rope based skills and equipment to access buildings, other structures (on or offshore), geological features (such as cliff faces), or manmade features (such as dams). A rope is used as the primary means of support and a safety rope is used to attach the fall arrest system.

Rope access may also include the use of aid climbing techniques.

A2.28 Climbing and aid climbing techniques used by rope access technicians may use techniques other than a safety line for fall protection such as positioning lanyards, backup lanyards and bypass lanyards.

A3.3 Before starting a particular job the employer shall carefully assess the work to be undertaken and ensure that all the potential hazards are identified. A site survey is required to determine the means of access, risks to people other than the employees and the nature of the working environment. From this assessment, employers can then prepare a suitable work plan, with necessary separate work plans being prepared for each particular aspect of the job. This statement should set out the general principles and working procedures for each particular situation which are to be followed by their employees and by independent contractors used. In many cases where types of jobs are similar, sections of the rope access work plan could be identical and might therefore be in the form of a general document.

A3.3.2 The Rope Access Administrator shall assess the individual team member's suitability for the work to be performed.

A3.4 Personnel permitting, planning, supervising and carrying out the work should ensure that the safety objectives given in the following paragraphs are met.

The primary objective is to organize, plan and manage rope access work so that there will be an adequate safety margin to minimize any risks.

Where the work site contains additional hazards, then the training, ability, experience, competence and size of the work team should be of a level that is suitable to deal with any emergency arising out of the work.

In circumstances where wet synthetic ropes may become a tracking path for electrical discharges, suitable precautions should be taken.

Except where work is laid out to allow horizontal traversing, work shall be planned such that workers can descend vertically, with the minimum amount of pendulum to minimize the risk of chafing the rope or overloading the rope or anchors.

Work should start from properly protected safe areas or areas made safe by the installation of temporary barriers or scaffolding. Such areas should also have a safe means of access.

Anchors should have safety factors that meet or exceed those required for the ropes. The attachment to the anchorage should at least equal the strength of the system attached to it. Re-direction of a rope from an anchor should not exceed 120 degrees unless the side loads produced at the redirection point are considered. Similarly, where the included angle at the attachment is high and produces a ‘multiplier’ effect, the extra forces produced should be considered.

All rope access workers should be properly supervised and self-supporting.

Work teams should consist of at least the minimum number of members required to ensure that should anyone require help they can quickly perform a rescue. To meet the above requirement, a work team should consist of at least two members. One member of the work team should be qualified as a Rope Access Supervisor or Lead Technician.

The Rope Access Supervisor should ensure that the provisions for rescue are adequate. Sufficient personnel should be readily available to provide assistance in the event of an emergency.

A3.5 Properly planned anchorages should be used. In some cases, anchorages must be installed prior to use. In such cases, a qualified person with experience in Rope Access Anchoring Systems should design an anchor point to be installed. In other cases, there will be a need to devise an anchor point from existing structures. Possible appropriate anchor points include but are not limited to steel members, I-beams, suitable trees of good size and mass, large boulders, heavy equipment and specially designed anchor points.

A3.6.1 In planning to meet these objectives, it should be noted that experience has shown significant safety benefits may be obtained if the system of work always includes the provision of at least one alternative means of support to prevent a person from falling. This means that should any one item fail within the suspension system, there will be an adequate back-up to prevent a catastrophic accident. However, in some situations such additional measures may cause greater hazard than they mitigate.

These situations should be thoroughly documented in the Rope Access Work Plan.

A4.8 People chosen for the work should have a suitable attitude for working at height.

To work safely at height requires those engaged in the work to have special characteristics. Prospective employees should have both aptitude and attitude that would not result in panic, cause them to make mistakes in a crisis, or work in a reckless or undisciplined manner. Aptitude and attitude may vary according to height and environment of work to be performed.

Frequently those who work at height will be remote or out of sight from their Rope Access Supervisor. It is, therefore, especially important that the workers can be always relied upon to behave in a sensible and responsible manner.

To assess whether a person is capable of performing this type of work requires detailed consideration of their previous experience. The employer should verify prior rope access training experience.

Other suitable experience could include mountaineering, caving and working at heights using other means of access.

Experience with the fire service or military forces may also be relevant if a person has been regularly engaged in the use of methods that involve being exposed at heights. Where practicable, references should be obtained to verify claimed experience and levels of competence.

The employer will be assisted in their verification and monitoring of a worker’s experience when their workers or applicants have a personal record log showing the training received and describing their work experience.

As part of their duties to maintain a safe place of work, the employer should control any tendency of employees to work in an undisciplined manner by recording this in their personal log books. An amending note canceling any adverse comments would not then be made until the employer is completely satisfied that there would be no recurrence.

Employers must ensure that employees maintain their level of ability. Refresher training should be provided for workers who have not been continuously engaged in this work. Due to the aptitude and mental conditioning necessary for working at height, workers who have not been engaged in rope access work for six months or more should attend a suitable refresher course before being allowed to work in this manner. This may be either a refresher course or a full course at the appropriate level.

A5.1 The Rope Access Program

Administrator will be responsible for setting up the employer’s Rope Access Program and developing or approving the Rope Access Work Plan. At minimum, the administrator should have the knowledge and experience of a

Level III Technician (Rope Access Supervisor) if not a certified Level III Technician. The administrator should also be knowledgeable about and experienced in supervising fall protection programs and in particular fall protection systems for rope access work.

A5.2.5 Appropriate supervision may not always require an administrator or supervisor to be on-site. Depending on the nature of the work and the qualifications of the workers, the on-site supervisor may not be required if it can be shown that the safety of the workers has not been decreased.

A10.3 Where the harness is to be used as the primary support, webbing on the leg loops should be of sufficient width and design to support the wearer in a comfortable and safe working position while allowing unhindered operation of other equipment and tools.

A10.4 Strengths listed are for single person loads. Higher strengths may be required to achieve similar safety factors for two person or rescue loads.

A10.5 For long descents, consideration should be given to the effect of rope-weight on descender performance. Consideration should also be given to reducing cumulative twisting of the rope.

A10.6 Rope grabs may be used to ascend a rope or to attach the operator to a safety line. In the event of a failure of the main line or loss of control by the operator, rope grabs are intended to grip the safety rope without causing damage to the rope and also help absorb any shock load which may occur.

A10.7.1 Ropes made from high modulus polyethylene, high tenacity polypropylene and “Kevlar” are types of ropes which may be considered in exceptional circumstances when the appropriate descent devices have been developed. These might be useful where there is severe chemical pollution or where the self weight of the ropes could be a problem. However, H.M.

polyethylene and H.T. polypropylene have much lower melting temperatures than nylon or polyester and may be affected by frictional heat from the descenders. Dangerous softening of polypropylene occurs at temperatures as low as 27 degrees C (80 degrees F).

Kevlar has a very high melting point but poor resistance to abrasion, UV light (including sunlight) and repeated bending.

A10.7.2 Life Safety Ropes should be selected which have an outer sheath that resists undue wear from edges and system components and tight enough to resist the ingress of dirt and grit. In most cases, this rope will be low stretch rope.

An example of calculating system safety factors is as follows: a 68 kg (150-pound) worker, to achieve a 5:1 safety factor, must work on a system where the weakest link of the system is calculated to be capable of sustaining at least 340 kg (750 pounds).

A10.9 Part of the permitting process for rope access work is the evaluation and determination of which standards apply to equipment being used for the type of work being done. Conventional “fall protection” equipment rated to ANSI A10.14 or Z359.1 may not be sufficient for rope access work due to different construction and performance requirements. Most equipment will meet a CE, ASTM, Cordage Institute or NFPA standard. The most critical element is to ensure that the equipment being used is appropriate for the job at hand.

A10.10 Records listing all equipment issued, referring to the original test or certificates of conformity should be kept.

In some cases it will be helpful if they also have relevant comments noting where the equipment was used, its storage conditions, and any incidents which could affect its life (e.g., unusual loadings, use in chemical or gritty atmosphere, exposure to salt-air, etc.).

The records shall note when each piece of equipment was inspected, by whom and any remarks concerning its condition at that time.

A11.1.3 Personnel in the Access Zone may require fall protection meeting the requirements of the jurisdiction or country of the work, such as ANSI/ASSE, CSA or EN/CE, during transition until the rope access anchors are established and personnel are on-rope.

A12.1 Hand or audible signals to be used for regular or emergency communications should be agreed upon and rehearsed before work begins.

A14.1 Work using rope access techniques may be more exposed than most other work…
