7 Introduction Title of the CP Scope CP is applicable to WAH in all industries Purpose Raise standard of safety where persons are exposed to the risk of falling from height Terms and Definitions Gives explanation to terms used 7/36

8 Design for Safety Elimination of risk at source, during design GUIDE process G U I D E Group, form review team of major stakeholders Understand, look at drawings and calculations Identify risks due to design or construction method Design around risks Enter information on remaining risks into register 8/36

9 Design for Safety All stages of work need consideration: Construction and/or installation Usage Maintenance and/or cleaning Demolition and/or decommission 9/36

10 Fall Protection Plan Policy Responsibilities Risk Management Control Measures Procedures PPE Maintenance Training Investigation Emergency Site specific Systematic approach for removing or reducing risk of falling from height Components 10/36

11 Fall Protection Plan Fall Protection Plan - required knowledge: Knowledge of work site Knowledge of processes Knowledge of risk assessment Knowledge of fall protection measures 11/36

12 Policy for Fall Protection Set by top management Clear no ambiguity Commitment & compliance Appropriate to the organisation s Needs Nature Scale Understood, implemented and maintained Reviewed 12/36

13 Responsibilities Top management Allocate sufficient resources Appoint Competent Person Competent Person Develop Fall Protection Plan Define responsibilities of staff Ensure compliance with regulatory requirements Report performance 13/36

14 Risk Management Risk Assessment Hazard identification Multi-disciplinary team Thorough knowledge of work Assessment Severity & likelihood Review Periodic Significant changes in workplace activities Occurrences of falls 14/36

15 Risk Assessment Determine Severity Determine Likelihood Minor No injury, injury or ill-health requiring first aid treatment only (includes minor cuts and bruises, irritation, ill-health with temporary discomfort) Remote Not likely to occur Moderate Injury requiring medical treatment or illhealth leading to disability (includes lacerations, burns, sprains, minor fractures, dermatitis, deafness, work-related upper limb disorders) Occasional Possible or known to occur Major Fatal, serious injury or life-threatening occupational disease (includes amputations, major fractures, multiple injuries, occupational cancer, acute poisoning and fatal diseases) Frequent Common or repeating occurrence Severity Likelihood Determine Risk Likelihood \ Severity Remote Occasional Frequent Minor Low Risk Low Risk Medium Risk Moderate Low Risk Medium Risk High Risk Major Medium Risk High risk High Risk 15/36

16 Risk Assessment Risk Level Acceptability of Risk Recommended Actions Low Acceptable No additional risk control needed. Conduct periodic review to ensure that assigned risk level is accurate and does not increase over time. Medium High Moderately Acceptable Not Acceptable Evaluate hazards carefully to ensure that risk is reduced to as low as reasonably practicable within a defined time period. Interim risk control measures, such as administrative controls may be implemented. Attention by management is required. Risk level must be reduced to at least Medium risk before work commences. Interim risk control measures should not be used. Risk control should not overly rely on personal protective equipment. If possible, the hazard should be eliminated before work begins. Immediate involvement by the management is required before work commences. 16/36

17 Risk Control Measures Follow hierarchy of control Ensure that controls do not pose new risks Review ensure effectiveness and relevancy Decreasing preference 17/36

18 Procedures Administrative control Can be coupled with other control methods Development should include those who perform the tasks Adequate communication e.g. during toolbox meetings 18/36

19 Fall Protection Plan Personal Fall Protection Equipment Short term contingency Last resort Additional measure 19/36

20 Inspection and Maintenance Pre-usage visual inspection and checks Maintenance program Operational Equipment (e.g. Ladders) Safety Equipment (e.g. Harnesses) Inventory of equipment that require maintenance Periodic maintenance, repairs, replacement Record keeping 20/36

21 Instruction and Training Information (theory, classroom) Training (practical, hands on) Analysis of training needs Many different possible channels Ensure understanding Induction New roles New work methods Emergency situations 21/36

22 MEWP Training Mobile elevated work platforms (MEWP) Pre-usage checks Site assessment (e.g. ground conditions) Unstable ground conditions Steep slopes Holes or obstructions Overhead obstacles / structures Traffic (vehicular or human) PPE needed Familiarisation 22/36

23 Accident/Incident Investigation Incident Investigation Investigation and analysis Determining deficiencies Corrective action Preventive measures Communication of findings Relevant parties Records to be kept Findings Outcomes 23/36

24 Emergency Response Emergency response plan Rescue equipment First aid Training of designated rescuers Procedures during emergency Rescue from suspension after fall arrest Suspension trauma issues 24/36

25 Suspension Trauma May occur to a person suspended in harness Blood pooling in legs Reduced backflow of blood to heart Severe injury or death Quick rescue Proper treatment of suspected victims 25/36

26 Supervision Especially important for new, inexperienced workers or workers under training Supervisors must be competent, with knowledge of the work they are supervising Supervisors must ensure: Safety measures are in place before work starts Workers are supervised Only workers that have been trained are to carry out the work 26/36

27 Access to and Egress from Work Areas Factors to consider Human traffic Materials transportation Surfaces and need for platforms Lighting Housekeeping and Material Storage Cleaner and safer workplace Increased productivity Roof access Guarding of holes and openings 27/36

28 Edge Protection Guardrails Locations that require edge protection Requirements (Height, strength etc.) Access points 28/36

29 Fall Protection Systems Safe practices and/or requirements for: Scaffolds Requirements (height, strength etc.) Tower scaffolds Elevating work platforms (MEWPs) Suspended gondolas Mast climbing work platforms 29/36

30 Individual Fall Prevention Systems Travel restraint systems Prevents falls through movement control Not designed to stop/arrest falls Industrial rope access systems Specialised form of abseiling Used where other forms of access are impractical High level of competency & 30/36 skill

31 Fall Arrest Systems Individual fall arrest systems Full body harness, lanyard, shock absorber, anchorage Full body harness, self retracting lifeline Points covered Checking for defects Limitation Possible hazards Rescue Calculation 31/36

32 Fall Arrest Systems Video Clip 32/36

33 Fall Arrest Systems Fall clearance distance Prevents users from striking the ground after a fall Calculation of Fall Clearance Distance Safety belts are not suitable Harnesses recommended Other hazards still present Length of lanyard Energy absorber extension Insufficient clearance height: Self Retracting Lifelines Short lanyard Height of worker Safety distance 33/36

34 Ladders and Step Platforms Portable ladders Height to base ratio Checking for defects Securing before climbing Step platforms Safe use of step ladders 34/36

35 Hazards of Working at Rooftop Types of fragile/brittle roofs Moulded or fabricated materials Glass Acrylic etc. Appropriate safety measures Safe access to work area Crawl boards Work platform MEWP (for low-rise buildings) 35/36
