ROPE ACCESS GENERIC WORK GUIDANCE

1.0 INTRODUCTION

We (company) have developed this generic method statement in accordance with IRATA and ISO guidelines.

Industrial rope access methods used at height and in confined space shall guarantee the highest possible level of protection for the technicians whilst working.

This statement is to be considered as part of an overall statement covering all access methods applicable at a site, not including those not relating to working at height.

This generic statement is valid for most of the works to be undertaken, however it should be regularly reviewed and amended by safety supervisors on site.

Should conditions of procedures change due to specific site conditions encountered during the course or the work, the site supervisor may prepare specific statements to encompass these conditions.

SCOPE AND REFERENCES

Scope

This generic method statement should provide general information to technicians engaged in rope access operations, in accordance with IRATA International Code of Practice and ISO 22846 requirements.

Out-of-scope:

This generic statement doesn’t replace the specific method statement done according to site and access specifications.

ANCHOR REQUIREMENTS / RIGGING / LIMITATIONS

Requirements

Statement: ► Anchors should have a minimum breaking load

of 15kN and meet the EN 795-A requirements

EN 795-A

      • An unquestionable structural point should have

a minimum breaking strength of 2 x 15kN = 30kN

      • Eyebolts shall be torqued according to

manufacturer’s instructions

Testing (chemicals): ► Chemical anchors shall be pull tested at 5kN for

3 min with a calibrated device before first use,

and thereafter at regular intervals.

IRATA references: ICOP 2.7.9, 2.11.2, 2.11.2.6,

Annex F / TACS 6.4.2, 7.7.25

ISO 22846-2 clauses: 7.7.3

Rigging of anchor lines

Statement: ► Separate anchorages shall be used for working

and backup ropes

      • A minimum of 2 points of anchorage shall be used

to anchor both the working and the backup line

      • Each rope is fixed to both anchorages, via
        • basic anchor
        • bunny ears knot
        • Y-Hang (figure of 8 + alpine butterfly).
  • The load should be equally shared between

both anchorages

Y-hang

< 90º

Basic anchor Bunny ears anchor Y-hang

  • Considering load sharing, the maximum angle

created by the ropes shall not exceed 120°

  • At the work site, a maximum of 90° can be used as an easy reference point to ensure the loading at each of the anchor points remains less than the load in suspension
  • 2 slings or 2 wire strops may be used on the same unquestionable structural point (e.g. H-beam)

to build a 2-rope anchor (basic anchor)

IRATA references: ICOP 1.4.2.5.3, 2.11.1.3, 1.4.2.5.1 2.11.1.2, 2.11.2.2

/ TACS 7.7.35

ISO 22846-2 clauses: 6.4.1.4 (d) (i), 7.6

Limitations

Statement: ► While using Y-hangs to anchor the ropes,

the following angles should be considered

(cf. 3.3.1):

  • α < 60° very good loading of anchors
  • 60° < α < 90° good loading of anchors
  • 90° < α < 120° acceptable loading of anchors

(each anchor will now bear the

equivalent force of the load in

suspension)

  • α > 120° NOT ACCEPTABLE
      • The maximum practicable angle should not exceed 90°
      • If, for some reason, it is not possible to keep

the angle < 120°, the risk assessment shall define whether a system is still safe or not, and/or where it has to be re-enforced.

Tensioned lines:

Statement: ► For horizontal tensioned lines, the maximu

angle created by the ropes loaded in the middle should not exceed 160°

Fa,b = m/[cos(a/2)]

2

For a weight M of 100 kg and an angle α of…

α = 60° → Fa,b = 57 daN (force applied to a and b) α = 90° → Fa,b = 70 daN

α = 120° → Fa,b = 100 daN α = 130° → Fa,b = 118 daN α = 150° → Fa,b = 193 daN α = 160° → Fa,b = 288 daN α = 170° → Fa,b = 574 daN α = 178° → Fa,b = 2865 daN

IRATA references: TACS 6.4.12

ISO 22846-2 clauses: Annex D

Deviation limitations:

        • The maximum angle for a single-anchor deviation shall not exceed 20º
        • In any case, the consequences of a potential swing should be risk assessed

Statement: ► A single-anchor deviation should only be rigged if,

and in case of unique anchor failure:

          • no rope friction, shock nor contact with an edge is possible
          • a potential swing is not dangerous for the technician nor third parties
          • the structure cannot be damaged by the resulting swing
        • A double-anchor deviation should be considered

if the the system doesn’t meet the safety requiments applied to a single-anchor deviation

Use a double-anchor deviation if an anchor failure could lead to a hazardous edge contact

Do NOT rig at the edge level and keep clearance distance

      • The dorsal D-ring sometimes marked A- shall

exclusively be used to connect:

        • fall arrest lanyards (EN 355)
      • The central lower D-ring of the harness

is considered an unquestionable point

  • If the top part of the harness (EN-361)

is connected to the sit via a single ‘Delta’ maillon, following should be done before considering the sternal D-ring as an unquestionable point:

    • The maillon should have a MBS of at least 15kN

and always be positioned in order to offer this MBS

    • A mechanical unscrewing of the maillon by hand shall not be possible
    • The maillon shall be torqued according to manu facturer’s recommendation
    • The screw should be sealed with ‘Loctite 243’ and the plastic cover sealed with silicone in

order to avoid any accidental removal

last choice, and best manufactured in Aramid

/ Kevlar or equivalent

EDGE MANAGEMENT & ROPE PROTECTION HIERARCHY OF MEASURES

Mechanical protection devices

Statement: ► Rope protection devices should be selected

according to risk assessment

  • Where rigging to avoid or prevent edge is not possible, pads, mats or specific construction should be used to mitigate the consequences

Rope protectors

Statement: ► For hot works, aramid/kevlar protection on each

rope should be used.

In addition, ropes should be “backed up” with wire strops

Source: Beal

  • No fabric rope protection shall be used if the edge radius is < 5 mm
  • Where rope protectors (eg mid-rope protection) have to be used, a thorough assessment should define whether:
    • one protector for both ropes
    • protector per rope

should be used. The stretch of the ropes should

also be considered

LOGGING OF HOURS WORKED

Statement: ► Working on ropes includes:

  • on-site work such as

→ rigging

→ de-rigging

→ gaining access

→ protection installation

→ rescue equipment installation and preparation

→ supervision (harnessed up) on-site

→ all workers directly in support of rope access teams

  • trials carried out on site such as

→ rescue practice

→ trial procedure testing

    • Working off ropes on-site includes:
      • site survey and inspection
      • waiting for permits
      • preparations prior to and post site working
      • direct on-site supervision
      • on-site job-related meetings such as tool box talks
      • preparatory work on site
      • any directly related work associated with

the work or job on site.

      • pre-use and post-use equipment inspections
      • down time because of weather
      • use of IRATA qualified personnel working

where rope use is not the primary support element

(e.g. working offcradlesand scaffolds)

      • where IRATA qualified personnel are in attendance

at the work site in support roles (winch operators,

communications etc) but who are not harnessed (for rescue duty).

Excludes unqualified support workers/supervisors who have no control or direct

involvement in rope access.

  • Other includes:
    • any time spent not covered by any other category such as

→ travel time

    • relevant admin support hours from head office

which is directly related to rope access such as

→ risk assessment

→ method statement preparation

→ equipment procurement and inspection

  • Cf. form reference No in section 23.0

LOGBOOK ENTRIES (Hours worked)

Should be an accurate reflection of the time spend carrying out rope access, including normal requirements such as pre-work requirements (toobox talk briefing), pre-work equipment inspection, rigging, de-rigging and training. Working with fall arrest methods

is of relevance only if used in combination with rope access

IRATA references: TACS 4.13, 4.14

ISO 22846-2 clauses: 4.17

  1. SUSPENSION INTOLERANCE (SUSPENSION TRAUMA)

Statement: ► The suspension trauma is a breakdown of the

normal blood circulation caused by the free, immobile suspension in a harness

    • The leg loops can squeeze the veins together

and thus prevent the blood circulation back to the heart

    • As the resistance below the feet is missing the

so-called muscle pump can no longer be effective

for the delivery of the venous reverse flow.

Thus big amounts of blood can remain in the veins of the legs and the blood circulation is not provided with enough blood. Vital organs as brain, heart and lungs are not sufficiently supplied.

    • The injured person should be removed as fast as

possible from the hanging position

    • The most frequent complication after a long hanging period is the right heart part failure, also called “rescue death”, and caused by the classic shock positioning

IRATA references: ICOP Annex G

ISO 22846-2 clauses: 8.2, Annex E
