Why do scaffolds collapse?

Poor design

Risk - Scaffold Collapse

Poor construction

Poor quality materials

Inadequate ties or sub-structure

Undermining or subsidence

Adverse weather High Winds


ver oa ng Interference

Vehicle or plant impact

Or a combination

Risk Falls from height

International Performance Standards


Poor standards of scaffolding indirectly caused by:

Lack of legislative framework

Lack of enforcement

Government Regulation

No meaningful penalties or deterrent for employers andworkers

Thereby scaffolding and access standards are then drivenby cost no perceived commercial consequences!

Results in:


n er or qua y o ma er a s use

Poor standards of assembly

Inefficiencies in the tasks to be performed

Avoidable accidents (collapses, falls etc)

Falls from height = Most Fatalities Worldwide!

Best Practice

Developing countries/states benchmarking establishedlegal frameworks:


European Directives

National Legislation (e.g. Labour Ministry, Department of Labour)

Health & Safety Executive (UK)

Occupational Health & Safety Administration (OSHA)

Tiered Approach:

Enforcement of Directives, Acts, Regulations, ACoPs


(Prescriptive Vs Goal Setting) Minimum Standards

(e.g. European or National Standards, Codes of Practice)

Guidance (Goal setting best practice)

Education and awareness campaigns

Best Practice Education and awareness campaigns

Best Practice

Establish minimum performance standards for:

Product Specifications (Design, Testing, Instructions etc)

Standards & Codes

Design Codes (minimum requirements for engineering design andcalculations)

Safe Practices (Codes of Practice)

Establishes minimum performance standards(demonstrate you did as good as?)

Provides Enforcement Guidelines for Government Authorities


an atory s o untary on orm ty

Developed with industry involvement (Trade Associations)

Provides minimum specifications for clients andcontractors

Best Practice

Policy conditions (minimum performance standards)

Role of com ulsor insurance E. . German & UK Models

Role of Insurers

Pro-active Risk Management Approach

Risk Management Survey (Industry experts)

Recommendations become compulsory requirements

Agreed timescales for improvement

Failure to comply may undermine cover


Competitive cover for good performers

Hardening of the insurance market for poor performers

Best Practice

Government Ministries/Authorities sponsor, support orestablish trade associations to produce industry guidance.

Industry Associations & Guidance

Guidance developed by industry experts(I.e. the National Trade Associations).

Used as enforcement guidelines and recommended bestpractice.

Provides minimum specifications for clients and contractors.


Best Practice

Clients who strive for world-class EHS standards

Scaffoldin S ecifications

Client Specifications

Material Specifications

Standards & Codes of Practice

Design requirements Training requirements

Safe systems of work

Ph sical re uirements e. . access methods fall rotection etc

Preventing Falls


Best Practice

NASC SG4 or similar adopted by many States/Countries(UK)

Preventing Falls

National Insurance Scheme dictate acceptable practices(Germany)

National Guidelines include non-specific requirements e.g.: Personal Fall Protection Equipment (PFPE) must be worn

Height they must be attached (i.e. 4m)


ca o ers mus e ra ne

Provide supervision

No meaningful guidelines in place (how, what, where)

PFPE Worn at all times

Preventing Falls

Clip-on at 4m

Use collective protectionbefore resorting to PFPE

Includes suitable andunsuitable anchor-points


ra n ng uperv s on PFPE Inspection

Sold over 150,000 copiesworldwide

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

The SG4 Safe Zone

Scaffolder must focus on creating a Safe Zone with:

A fully boarded platform without gaps

A sing e main guar rai 950mm , w ere t ere is a ris oa fall.
