Concept of Safety vs ALARP vs continuous improvement in risk mgt General safety rules in scaffolding.  The Term “Scaffolding” In Education : It refers to process through which teacher supports students to help facilitate learning and aid mastery of skills. It entails breaking a lesson into different levels and providing tools for students for each chunks  Scaffolding Strategies Tapping into prior Knowledge Pre-teaching Vocabulary Questioning and Visual aids. In Medicine: Scaffold is a frame work or structural element that hold/supports tissue together. E.g use of biomaterials like tissues, tendon to support bones during healing. In Construction Scaffolding helps to provide support for working at height. E.g for window cleaning, roof works, bill board installation, painting of house etc. What is work at Height?  Work at height Is any work that is carried out at a place where one could fall a distance liable to cause personal injuries and injuries to others e.g Statistics  QUIZ? At what height can one said to be working at Height? What does the laws say? WORK AT HEIGHT REGULATION 2005 WAHR 2005 posses that: 1. There is no minimum height for working at height. 2. It places emphasis on the need for risk assessment 3 It also lays emphasis on the need for the job to be properly planned, supervised and carried out by competent person.  Planning for work at Height Consider: the work activity Other activities around (impact it can possibly have on the work). equipment to be used. location of the work, check for any hazards the work environmental condition (is the weather suitable) Condition of the existing work surfaces Duration of the work the workers (are they competent and capable of safe work delivery)  Various Equipment for working at height Movable Elevated working Platform (MEWP) Ladder.

It shows that scaffolding is a well guided endeavours. It prickles us to know about the legal guidelines. It pictures in the mind the need to only engage competent individuals who have been trained on the legal requirements for safe operations.  Legal Guidelines ❖ The health and safety at work act 2005 ❖ The provision and use of work equipment regulations 1998. ❖ Management of health and safety at work regulations 1998 ❖ Working at height regulations 2005 ❖ Manual Handling regulations,1994 Code of practice: - SG 4:20 - TG 20:21 - BS EN 12811 – 1 Note: US Guidelines on scaffolding 29 CFR 1926.451  Health and Safety at work act 2005 The act places duties on everyone at work: The employer who MUST provide: A safe place of work A safe system of work Safe plant and equipment Training, information, instruction and supervision. The employee who MUST: Take care of themselves Take care of anyone who may be affected by their actions. The self employed who have the same duties as the Employer and Employees  Provision and Use of work Equipment Regulations (PUWER)1998 PUWER places duties on the employers and suppliers to provide equipment for use at work which meets three basic criteria: It must be fit for use (it must work) It must be fit for it’s intended purpose (It must do what you want it to do). It must comply legally and meet all standards (as might be required). Management of Health and Safety at work Regulation 1998 This regulations place duties on employers to carry out risk assessment on all work activities which will identify risks to peoples health and safety. Hazards found during work activities which have the potential to cause harm need to be removed If possible or if this is possible they must be controlled in such a way as to reduce the likelihood of harm to the lowest possible risk  Work at Height Regulations 2005 These regulations place duties on employers to do all that reasonably practicable to prevent anyone from falling. The regulations highlight the hierarchy of controls for managing and selecting equipment for work at height:  Note: The best time for tackling hazards is from the design stage. At this point control can be less expensive and easily carried out. Building Design  Manual Handling Regulations 1994 These regulation places duty on employer to carry out risk assessment on activities which may involve manually: Ways to reduce the risk of manual handling injuries: Remove the need to manually handle loads. Redesigning the work place or equipment or redesigning the work process to reduce manual handling operations Reducing the size, weight, shape or centre of gravity of loads; Making available mechanical means so loads can be moved easily and safely Lifting Equipment Lifting Operations Regulations 1998 (LOLER) These regulations (LOLER) applies to any work equipment used for lifting or lowering loads. It requires that lifting equipment and accessories for lifting are inspected within stipulated period. Also that S.W.L of the equipment or accessories must be indicated and also that S.W.L must not be exceeded. Gin Wheel (Mechanical aid for lifting Materials)  Codes of practice These are specific detailed information on how to achieve compliance with respect to a particular standard. It shares information on work ethics, guidance and operational procedures with respect to standard. Note:Code of practice is usually from professional bodies e.g NASC (uk) releases codes of practices on scaffolding.  Codes of practice: SG4:20 Focuses on Prevention of falls  TG 20:21 TG20:13 Technical guidance of design of tubes and fitting This guidance focuses on the various materials requirements for tubes and fittings scaffold. It addresses: the sizes of board , thickness the tubes thickness , sizes the couplers  BS EN 12811 BS EN 12881 – 1 , specifies the performance requirements and methods for structural and general design for access and working platform for prefabricated scaffold.  Other codes of practice SG 5:18 Overhead power sources and Earthing of scaffold structures Work at height restriction barriers Safe distances from power lines with respect to Voltages: Low voltages 1m 11kv and 33kv 3m 132kv line 6m 275kv and 400kv lines 7m Scaffold Inspector He is someone who has been trained on the legal requirements guidance for safe scaffolding. He does assessment of scaffold in accordance with the legal Guidance. He is the only one that confirms if scaffold is safe to use or otherwise. Scaffold Tagging, Certification and handing Over Note: Scaffolds with a “red tag” are not safe and should not be allowed to be used. Risks and controls in scaffolding SAFETY  What is safety? Safety is that condition of work where every risks have been reduced to ALARP. ALARP: As Low As Reasonably Practicable Concept of ALARP ALARP is a concept of risk management that centered on using measures that the costs are not grossly disproportionate to the desires results  Note: Reasonably practicable entails weighing risk controls method against: ❖ Trouble/Efforts required ❖Time required ❖Cost Involved ❖Result to be achieved For example: 1. To propose 1million naira for treating 5 personnel with bruised legs 2. To propose 1million naira for prevention of explosion that could kill 200 personnel.  Deduction from ALARP Theory ❖ That there is no risk free environment, every environment got it own level of risk. ❖ That we must continuously look in the way of continuous improvement. What is continuous Improvement ? Continuous Improvement is a concept of risk management that entails one should continuously look for way for an improved version of control measures.  How do we drive continuous Improvement By ensuring: ❖ Continuous assessment and re – assessment ❖Continuous Engagement and re-engagement ❖Continuous Inspection and re-inspection ❖Continuous alignment and re-alignment  10 Useful tips on scaffold Safety Always engage competent person Ensure that ground surface is firm and level Scaffold to tagged to indicate status: safe or unsafe Never overcrowding scaffold with equipment and personnel Personnel must be allowed to stretch over guard rail.  Ensure scaffold is always inspected before use. Double lanyards harness to be used by personnel working on scaffold, this is to allowed for safe movement. Scaffold to be inspected after every 7 days and after inclement weather condition. Thanks for attention
