accidents in australia
Accidents in Australia
  • In 1995 / 96 figures in NSW
    • construction 53.9/1000 workers
    • mining 76.2/1000 workers
    • industry average 27.4/1000 workers

ACCI Safety Research

slide3

Safety Research at ACCI

  • Trade specific Hazard Profiles.
  • Standardized documents
  • Techniques for risk assessment
  • Site Safety Meter technique.

ACCI Safety Research

slide4

Hazard Profile Development

  • Initial focus on highest risks
    • demolition & roofing
  • Next stage covered 7 other trade packages
    • concreting, reo, formwork, plumbing, electrical, masonry & scaffolding

ACCI Safety Research

slide5

Development Process

  • Iterative process with industry
  • Identified discrete activities
  • Identified hazards for each
  • Developed strategies to manage each hazard

risks in demolition
RISKS IN DEMOLITION
  • By a numerical method (Fines)
  • Risk ratings widely scattered
  • achieved greater transparency by modifying graphical approach

(Kinney and Wirruth)

ACCI Safety Research

fine s method
Fine’s Method
  • Risk rating R=C*E*P
    • =Consequence*Exposure*Probability

ACCI Safety Research

fine s criteria
Fine’s Criteria
  • Very high >350
  • High 180 - 350
  • Substantial 70 - 180
  • Moderate 20 - 70
  • Acceptable <20

ACCI Safety Research

committee rating variation
Committee Rating Variation
  • Rating for an electric shock from a temporary connection
    • 1 150 substantial
    • 2 100 substantial
    • 3 450 very high
    • 4 6000 very high **
    • ** this value was ignored as the descriptions were misunderstood

ACCI Safety Research

exposure frequency of the occurrence of the hazard event
Exposure(frequency of the occurrence of the hazard event)

Continuously (or many times daily) 10

Frequently (approximately once daily) 6

Occasionally (from once a week to once a month) 3

Unusually (from once per month to once per year)2

Rarely (it has been known to occur) 1

Remotely possible (not known to have occurred) 0.5

ACCI Safety Research

consequences most probable result of the potential hazard
.Consequences (most probable result of the potential hazard)

Catastrophe; numerous fatalities; damage over $1,000,000; major disruption of activities 100

Multiple fatalities; damage $400,000 to $1,000,000; 50

Fatality, damage $100,000 to $500,000; 25

Extremely serious injury (amputation, perm’t disability); damage $1,000 to $100,000; 15

Disabling injury; damage up to $1,000; 5

Minor cuts, bruises, bumps; minor damage. 1

ACCI Safety Research

probability likelihood that accident sequence will follow hazard event
Probability (Likelihood that accident sequence will follow hazard event)
  • The complete accident sequence:

Is the most likely and expected result if the hazard-event takes place; 10

Is quite possible, not unusual, has an even 50/50 chance; 6

Would be an unusual sequence or coincidence; 3

Would be a remotely possible coincidence; 1

Has never happened after many years of exposure, but is conceivably possible; 0.5

Practically impossible sequence (has never happened). 0.1

ACCI Safety Research

variables
Variables
  • Consequence agreement on a fatality 50
  • Exposure 2 selected 1rare 1 selected 3occasionally
  • Probability 2 selected 3unusual but possible 1 selected 1remotely possible

ACCI Safety Research

experience re fine s method
Experience re Fine’s Method
  • Process lacks transparency
  • Training in use needed
  • R is influenced by subjectivity
  • Unacceptable variability in ratings is unavoidable

ACCI Safety Research

risk ratings conclusions
Risk ratings - conclusions
  • Both methods rely on subjective judgements
  • The graphical method makes these judgements transparent

ACCI Safety Research

current approach
Current Approach

THREE LEVELS

  • fatality
  • serious injury
  • minor injury

ACCI Safety Research

standard terminology and documents
Standard Terminology and Documents
  • Job Safety Analysis (JSA)
  • Safe work method statement
  • Work method statements
  • Hazard analysis
  • Risk analysis

ACCI Safety Research

slide22

Site Safety Meter

  • Based on the Finland TR Index
  • “Positive” rather than “Negative”.
  • Relatively objective & fast
  • % score
  • Graphical output

ACCI Safety Research

slide23

Site Safety Meter

  • Measures specific categories against a prescribed criteria.
  • Provides both behaviour and systems feedback on site safety performance.

ACCI Safety Research

slide24

Measures Specific Categories

FOR BUILDINGS

  • Working habits
  • Order and tidiness
  • Electricity and lighting
  • Scaffolding & ladders
  • Edge protection, falls & falling
  • Plant and equipment

ACCI Safety Research

slide25

Selection of Categories

Construction fatalities NSW 87/88 (154)

Predominant causes:

  • Falls from height. 41 (30%)
  • Contact with electricity 32 (21%)
  • Hit by moving object. 29 (19%)
  • Hit by falling object. 23 (15%)

Method of measurement

Example-Cat 1 “Working Habits”

  • One reading / worker / area.
  • For a “correct” score, a person uses PPE or safety equipment correctly
      • harness attached near edge
      • ear & eye protection using saw

ACCI Safety Research

slide27

Method of measurement

  • Example-Cat 4 “Scaffold & Ladders”
  • One obs/scaffold section & ladder/area
  • For a “correct” score:
        • Adequately braced and tied
        • Mobile assembled correctly, ladder, bracing & toeboards.
        • No large gaps between perimeter edge and scaffold.
        • Ladder tied off & angled correctly

Safety Score

Formula for Score as a %

Feedback

ACCI Safety Research

slide30

Advantages

  • Provides “(+)”, not “(-) feedback.
  • Snapshot of safety environment
  • Stimulates the safety culture

ACCI Safety Research

slide31

Weaknesses

  • Difficult to look beyond negatives,
  • Risk class is not considered.

a site may score highly but still have a number of Class 1 (high) risk safety defects.

ACCI Safety Research

slide32

Preliminary trial results

8 companies & 13 sites

60 site visits  10,000 data

  • Initial average SS 79%.
  • After 12 months:
  • Average score 85%.
