ISO 22846-1:2003

Overview

ISO 22846-1:2003 - Personal equipment for protection against falls - Rope access systems - Part 1: Fundamental principles for a system of work - provides the foundational principles for safe rope access work at height. Published by ISO, this standard defines the scope, terminology and core safety requirements for rope-access operations where ropes are the primary means of access, support and fall protection. It is intended for employers, employees, self‑employed operatives, clients who commission rope‑access work and rope‑access associations.

Key topics and technical requirements

• Scope and definitions: clear terms (working line, safety line, anchor, ascender, descender, back‑up device, workmate rescue, etc.) to ensure consistent use of rope access vocabulary.
• Double protection principle: at least two independently anchored lines (working line + safety line) or equivalent back‑up to prevent a fall if one component fails.
• Equipment and inspection: selection of appropriate harnesses, ropes and devices; pre‑use inspections and regular thorough inspections; traceability to manufacturer/supplier and proper storage/maintenance.
• Connection and harness use: primary connections of both working and safety lines must be via the harness (sit or full‑body). Workseats do not replace fall‑protection connections.
• Rope‑access devices: requirements for descenders (controlled descent, heat dissipation, fail‑safe/auto‑stop desirable) and back‑up devices (must withstand foreseeable forces).
• Operational safety limits: avoid falls that produce impact forces > 6 kN; prevent impacts with ground or obstructions.
• Planning, supervision and competence: designated planner/supervisor, hazard identification, risk assessment, suitably trained and competent operatives, and team minimums (teams of two, with competent supervision).
• Rescue and communications: mandatory workmate rescue/retrieval plans, on‑site rescue capability, and reliable team communication.
• Exclusion zones and third‑party protection: control of worksite to protect public and operatives.

Applications and who uses it

ISO 22846-1 applies to rope access on buildings, industrial structures (on‑ or offshore) and natural features (cliff faces) where ropes are the primary means of access, egress or support. Typical users and beneficiaries:

• Rope access technicians and contractors
• Employers and safety managers in construction, inspection, maintenance and industrial rope work
• Facility owners who commission rope‑access services
• Training providers and accreditation bodies
• Rope‑access associations and standards committees

Practical uses include façade maintenance, offshore inspection, bridge and tower work, confined‑space access, and any work‑at‑height task where rope access offers an efficient alternative to scaffolding or powered platforms.

Related standards

ISO 22846 is a multi‑part series; Part 2 (code of practice) complements Part 1. Users should also consult national regulations and other ISO standards on personal fall protection and equipment inspection applicable to their jurisdiction.
