International Scaffolding Best Practice: 22 June 2011

The document discusses international best practices for scaffolding safety. It addresses major scaffolding hazards like falls, falling objects, and collapse. It emphasizes preventing falls through proper use of personal protective equipment, fall arrest systems, and safe working platforms. The document also covers rescue planning, ensuring scaffold stability through adequate ties and bracing, standards for access and egress, the importance of scaffold design engineering, regular inspections, and proper training and certification of scaffolders. It proposes a new international scaffolding training and certification scheme.

Major Scaffolding Hazards

Simian S K I L L = Safety + Training + Access Consultants 3


Risk – Interface with the Public

Simian S K I L L = Safety + Training + Access Consultants 4


Risk - Scaffold Collapse

Simian S K I L L = Safety + Training + Access Consultants 5


Risk - Scaffold Collapse
Why do scaffolds collapse?
 Lack of competent design
 Poor construction
 Poor quality materials
 Inadequate ties or sub-structure
 Undermining or subsidence
 Adverse weather – High Winds
 Overloading
 Interference
 Vehicle or plant impact
Or a combination…

Preventing Falls
 Clipped on – 6kN Anchor Points!

Simian S K I L L = Safety + Training + Access Consultants 12


Preventing Falls
 Safe Working Platforms

Simian S K I L L = Safety + Training + Access Consultants 13


Preventing Falls
 Safe Working Platforms

 Scaffolder’s Working Platform  User’s Working Platform

Simian S K I L L = Safety + Training + Access Consultants 14


Preventing Falls
UK Case Study…
 NASC SG4
 PFPE Worn at all times
 Clip-on at 4m
 Use collective protection
before resorting to PFPE
 Includes suitable and
unsuitable anchor-points
 Training & Supervision
 PFPE Inspection
 Sold over 150,000 copies
worldwide

Accident Performance - Falls
 According to NASC accident statistics
 Falls form a working platform or scaffold
 Significant reduction in falls since 2000
 1999 – 93 falls
 2009 – 20 falls
 78% reduction
 18.6% increase in operatives
(10,679 – 13,124)
 84% reduction in Accident Frequency Rate

The SG4 Safe Zone
 Scaffolder must focus on creating a Safe Zone with:
 A fully boarded platform without gaps
 A single main guardrail (950mm), where there is a risk of
a fall.

Simian S K I L L = Safety + Training + Access Consultants 18


The SG4 Safe Zone
 Decking out below, where possible.

Simian S K I L L = Safety + Training + Access Consultants 19


The SG4 Safe Zone
 Features the tunnelling principle

Simian S K I L L = Safety + Training + Access Consultants 20


The SG4 Safe Zone
 Must be clipped on within 1m of the leading edge

Simian S K I L L = Safety + Training + Access Consultants 21


The SG4 Safe Zone
 Must be clipped on when working below the guardrail

Scaffold Design Engineering

Simian S K I L L = Safety + Training + Access Consultants 47


No Design Input – Wind Impact

Simian S K I L L = Safety + Training + Access Consultants 48


Design Variation – Inadequate Ties

Simian S K I L L = Safety + Training + Access Consultants 49


More than 10m’s high – Not Tied

Simian S K I L L = Safety + Training + Access Consultants 50


Scaffold Inspection

Simian S K I L L = Safety + Training + Access Consultants 51


Scaffold Inspection
Best Practice…
 Statutory vs Voluntary
 Frequency of Inspections
 Before use
 Every 7 days
 After substantial alteration
 After any event that may jeopardise
safety
 Visual or more rigorous inspections
 Testing, where required (e.g. ties)
 Inspector Competence
 Reports & Tagging Systems
