Commercial Building Window Washing Fall Protection Rigging Check
This procedure outlines the mandatory daily inspection and verification of all personal fall arrest system (PFAS) components, roof anchor points, and rescue equipment before commencing window washing on commercial buildings. Compliance with WorkSafeBC, CSA Z259, and ANSI/ASSP Z359 standards is required.
To ensure all fall protection rigging components (anchor points, full-body harness, self-retracting lifeline, connectors, rescue device) are structurally sound, properly matched, and correctly installed before any worker is exposed to a fall hazard while performing commercial window washing. A systematic pre-use inspection reduces the risk of serious injury or fatality and meets regulatory requirements for documentation.
Applies to all window washing crews or sub‑contractors performing work on commercial buildings where an unprotected fall of 3 metres (10 ft) or more exists. Covers suspended systems (boatswain’s chair, power rigs) and supported systems (ladder with fall arrest). Does not cover aerial lifts or scaffolding, which have separate SOPs. All workers must hold a valid fall protection certificate and have received site‑specific orientation.
- Lockout/Tagout any mechanical window washing equipment that could move unexpectedly (motorized rigs, counterbalance systems). Verify power isolation before handling cable or drums.
- Never use fall protection equipment that is past its service life, has been subjected to a fall, or shows any sign of damage. Remove defective equipment from service immediately and tag as “DO NOT USE”.
- Identify all sharp edges, abrasive surfaces, or hot surfaces where lifelines or lanyards may come into contact. Use edge protectors or reposition anchor points to prevent chafing.
- A written rescue plan must be in place and rehearsed before any worker ties off. Ensure rescue device is within easy reach and operator is trained in its use.
- Full-body harness (CSA Z259.10 compliant)
- Self-retracting lifeline (SRL) or energy-absorbing lanyard (CSA Z259.11)
- Anchor slings or beam clamps (min 5000 lb rating)
- Carabiners, snap hooks, and connectors (all auto-locking)
- Edge protectors (rubber or Kevlar sleeves)
- Rescue tripod with winch and descent controller
- Lighting (flashlight) for inspection of dark corners
- SafeDesk app or paper inspection checklist
- Radio or signaling device for communication
