- 5. WHO IS AT RISK ? • Work near unprotected open edges or floors • Work near unprotected penetrations or openings in floors or walls • Work near unguarded shafts or excavations • Work near or from unstable structures • Work where a person could fall into water, acid or poisonous solutions.
- 7. WHO IS AT RISK ? • Work on, or near, fragile or brittle surfaces • Work where a person could fall onto sharp or projecting objects such as exposed reinforcing steel, a picked fence, broken glass etc.. • Work where tools, equipment or material could be dropped to a person below.
- 10. HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS • Identify all tasks that could involve someone falling • Idendify any objects that could fall onto someone • Identify anything dangerous that anyone could fall into or onto • Identify any other risks to workers • Identify any risks to the general public What do I need first?
- 12. • Ladders • Boards or similar equipment for use on roofs • Electrical equipment, cables and other machinery tools HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS What equipment is generally involved?
- 13. • Scaffolds or perimeter guard railing • Other temporary work platforms, such as elevated work platforms HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS What equipment is generally involved?
- 16. HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS How do I control the Risks? Spot the Hazards Assess the Risk Fix the Problem Evaluate Results
- 17. HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS Spot the Hazards •If working on as roof, consider the pitch, whether it is slippery or reflective, and the capacity of working surface to support the intended road. •Training and experience of workers, e.g. New or inexperienced workers may be involved and the level of supervision needed may have to be considered. •The weather conditions, e.g. poor lighting, making unguarded edges and openings difficult to see. •Anchorage points for the attachment of safety harnesses. •The width of work area.
- 18. HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS •Obstructions in the work area caused by equipment, building materials, tools and rubbish •Uneven work sufaces •Wet, oily, glazed or otherwise slippery work surfaces •The extent and type of work to be undertaken •Unstable objects such as sheets of plaster that may be caught by the wind •Large and heavy equipment that may need to be raised to the work surface Spot the Hazards
- 19. HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS •The necessity to move from one height to another •The number and movement of everyone on site •Inadequate safety systems, e.g. No procedures for performing tasks safely or for using personal protective equipment •The possibility of debris or objects falling onto others •The possibility of someone falling into or onto something dangerous •The lack of or inadequacy of warning notices Spot the Hazards
- 20. HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS Assess The Risks •How likely is the hazard to cause harm to someone? •What is the worst possible damage the hazard could cause in terms of human suffering and cost if you don’t resolve problem?
- 21. Some things to consider: •How many people are exposed to the risk? •Sometimes it may be the amount of time workers spend on an activity that creates the safety risk, rather than the nature of the work task itself, e.g. prolonged exposure to hot sun could cause dizziness. •Everyone is different.A hazard may pose more risk to some people than others because of differnces in physical strength, experience, training etc.. HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS Assess The Risks
- 22. HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS Fix the Problem Once hazards have been identified and the risk assessed, you need to start thinking about how you can fix the cause of each identified risk Some problems may be fixed easily, while others will require more effort and planning to resolve.It is therefore important to concentrate on the most urgent hazards without neglecting the simpler ones.That is, don’t focus on just the complex solutions, as that could mean to overlook hazards that could be easily fixed, such as rubbish that someone could trip over. When it comes to controlling risk, some methods are more effective than others. For example, it is far better to make sure there are no obvious objects that can fall onto people than to put up as sign warning of “falling objects”.
- 23. HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS Evaluate the Results Hazards and risks need to be managed on an ongoing basis, especially where the weather is concerned. Review your safety solutions regularly to make sure they are effective. It is important to make sure your controls do not introduce new hazards. To assess the success of your risk control methods, talk to everyone involved and consider the types of accidents that have occurred in your industry. Be sure to seek advice from those affected by the changes and include them in any modifications to their work or work routines. It is also essential to consider training.
- 24. HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS •Ladders Ladders will only be used for works of a minor nature. Ladders will not be used on elevated floor levels near the perimeter of the building where there is a danger of a person falling.
- 25. HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS •Guardrails Guard rails must be fitted to all elevated work platforms. The guard rails should be of a height and construction to withstand loads which could reasonably be expected to be imposed on them. Where specifications are prescribed by local regulatory bodies for these, they will be observed
- 26. HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS •Fall Arrest Systems Individual fall arrest systems are classified as personal protective equipment, which means these systems should be used only after other controls such as elimination; isolation and substitution have been considered. The appropriate standards and codes of practice should be applied when using this system.
- 27. HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS • Fall Arrest Systems • You may want to apply a You may want to apply a “TOTAL TIE OFF” or “TOTAL TIE OFF” or “100% TIE OFF” system “100% TIE OFF” system where the worker uses where the worker uses TWO lanyards with one TWO lanyards with one ALWAYS tied on ALWAYS tied on • The other used for to The other used for to facilitate movement. facilitate movement.
- 28. HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS • 100% tie offs are used on this project and the operations are closely monitored. • These are usually used at very high locations but may also be used where access/egress is limited or where platforms and guard rails are not practical.
- 29. HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS •Roof work Protection must be provided for all persons that are required to work on roofs where there is a danger of persons falling including: •through the roofing material; •from the edge of the roof; •through skylights or penetrations •while accessing a roof.
- 30. HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS Methods of protection available include: •scaffolding, guardrails combined with existing safety mesh where the safety mesh is in sound condition, purpose built purlin platforms or trolleys, purpose built roof ladders, safety nets, catch platforms. •Where none of the above systems are practicable, individual fall arrest systems.
- 31. HOW TO MANAGE THE RISKS OF FALLS FROM HEIGHTS •Protection of Openings and Penetrations Open sides of all floors, roofs stairwells, lightwells, lift shafts and any place from which a person or object could fall will be securely covered with rigid material or provided with guard rails and toe-boards.
