1PowerPoint presentation Unit 201: Health safety and welfare in constructionKnow about access equipment and working at heights, and how to work with electrical equipment
2Objectives By the end of this session you will be able to: Identify legislation relating to working at heightsIdentify types of access equipmentState safe methods of working with access equipmentIdentify dangers of working at heightState precautions to take to avoids risk to self and others when working with electrical equipmentIdentify voltage and voltage colour coding that are used in the workplaceState methods of storing electrical equipment
3Legislation relating to working at heights The Working at Height Regulations 2005 (WAHR)The Regulations apply to all work at height where there is a risk of a fall liable to cause personal injury.This legislation places a legal duty on everyone for the welfare of employers, employees and managersThere is a simple hierarchy for managing and selecting equipment for work at height. Duty holders must:Avoid work at height where they can;Use work equipment or other measures to prevent falls where they cannot avoid working at height; andWhere they cannot eliminate the risk of a fall, use work equipment or other measures to minimise the distance and consequences of a fall should one occur.
4Working at height The Statistics Falls are the biggest cause of workplace fatalities35 fatal incidents in 2008/09 and a total of 421 since 2001Cause of 4589 major injuries 2008/0987% of all major injuries are caused by ‘low falls’ (i.e. below 2 metres)Where work has to be carried out at height, then the duty holder shall take suitable and sufficient measures to prevent, so far as is reasonably practicable, any person falling a distance liable to cause personal injury’ (WAHR)REMEMBER that injury can occur from a fall of any height, not just from above 2 metres.Look at the video on working at heights make notes:
5Working at heightsWhat are the six steps to safety when considering working at height?Using activity sheet 13 in groups identify the six steps to safety in the previous video.What are the steps ? What do they mean?
6Types of Access Equipment TrestlesMobile towersLaddersStepsHop upsTubularScissor liftCherry picker
7LaddersEvery year an average of 14 people die and a further 1200 are seriously injured at work as a result of falling from a leaning ladder or stepladder.Some of these accidnets will be a result of bad planning or use of the wrong piece of equipment for the job.What are the reasons people fall from leaning ladders and stepladders?The leaning ladder slipping either at the top or bottom;The leaning ladder flipping over or coming away at the top;overstretching;A fault with the ladder;Slipping or loosing your footing;Stepladder wobbles due to missing feet or not being correctly open;Stepladder being used side-on to the work task.
8LaddersPositioning a leaning ladder safely - Ladder showing correct 1 in 4 angle (Securing omitted for clarity).Positioning a leaning ladder with a side slope - Ladder showing maximum angle at 16° on a side slope.Positioning a leaning ladder with a back slope - Ladder showing maximum angle at 6° on a back slope.Ladder tied at topstiles (correct for working on,not for access
9LaddersIncorrect - overreaching and not maintaining three points of contactCorrect - user maintaining three points of contactIncorrect - stepsside-on to work activityCorrect - stepsfacing work activityA ladder should lean at an angle of 75º, i.e. one unit out for every four units up
10Trestles / Hop-upsTrestle scaffold should always be erected on firm, level ground and with a minimum working platform width of 450mmLockable steel hinges and anti-slip feet. Ideal for low level access, painting, plasteringPremium quality steel mobile steps for easy step-up access in the workplace.
11Mobile Tower Watch the short video clip HSE key messages are that:you must be competent in erection and dismantling of mobile scaffolds; andyou must always read and follow the manufacturer's instruction manual and on no account attempt use the equipment beyond its limitations.Watch the short video cliprt/videos/wareing18.wmv
12Mobile TowerCommonly referred to as mobile access towers or mobile scaffold towers, these structures are manufactured from prefabricated components where the principal structural materials are aluminium alloys or fibreglass.Wheels or feet of the tower must be in contact with a firm surface. Outriggers should be deployed as specified by the manufacturer.Mobile Access Towers are covered by PASMA. More Information
13Spot the hazardsIn groups list the hazards you can see compare findings with the class
14Mobile elevating work platforms (MEWPs) Take a look at this scene. Do you see a hive of safe activity? Or a high risk high street that's about to come crashing down? Mobile elevating work platforms (MEWPs) can provide a safe way of working at height.They:allow the worker to reach the task quickly and easilyhave guard rails and toe boards which prevent a person fallingcan be used in-doors or outMEWPs include cherry pickers, scissor lifts and vehicle-mounted booms
