BUSINESS AND TRAINING • • • • 39 BUSINESS AND TRAINING 39 the ladder could become unstable or collapse. Check the steps or treads on ladders – if they are contaminated, they could be slippery; if the fixings are loose on steps, they could collapse. Check the bracing is not loose or worn. Check the ropes and pulleys (if applicable) move freely and are not worn or damaged. Check the guides: the parts must move easily and freely along the guides. If you spot any of the above defects, don’t use the ladder as an incident may occur, and also the supervisor or employer needs to be notified. Using your ladder safely Once you have done your ‘pre-use’ checks, there are simple precautions that can minimise the risk of a fall. • Leaning/Extension ladders When using a leaning ladder to carry out a task: - - Only carry light materials and tools – Ladder showing the correct one in four read the manufacturers’ labels on the angles. ladder and assess the risks. - - Don’t overreach - make sure your belt buckle (navel) stays within the stiles. - - Make sure it is long enough or high enough for the task. - - Don’t overload it – consider workers’ weight and the equipment or materials they are carrying before working at height. Check the pictogram or label on the ladder for information. - - Make sure the ladder angle is at 75° - you should use the one in four rule (i.e. one unit out for every four units up). - - Always grip the ladder and face the ladder rungs while climbing or descending – don’t slide down the stiles. - - Don’t try to move or extend ladders while standing on the rungs. - - Don’t work off the top three rungs, and try to make sure the ladder extends at least 1m (three rungs) above where you are working. - - Don’t stand ladders on moveable objects, such as pallets, bricks, lift trucks, tower scaffolds, excavator buckets, vans, or mobile elevating work platforms. - - Avoid holding items when climbing (consider using a tool belt). - - Don’t work within 6m horizontally of any overhead power line, unless it has been made dead or it is protected with insulation. Use a non-conductive ladder (e. g., fiberglass or timber) for any electrical work. - - Maintain three points of contact when climbing (this means a hand and two feet or two feet and one hand) wherever possible. - - Where you cannot maintain a handhold, other than for a brief period (e.g. to hold a nail while starting to knock it in, starting to screw, etc.), you will need to take other measures to prevent a fall. - - For a leaning ladder, you should secure it (e.g. by tying the ladder to prevent it from slipping either outwards or sideways) and have a strong upper resting point, i.e. do not rest a ladder against weak upper surfaces (e.g. glazing or plastic gutters). - - You could also use an effective stability device. - - DO NOT attach a safety harness to the ladder. - - Extension ladders over 14m must be secured at the base and top. • Stepladders When using a stepladder to carry out a task: - - Check all four stepladder feet are in contact with the ground and the steps are level. - - Only carry light materials and tools. - - Don’t overreach. - - Don’t stand and work on the top three steps (including a step forming the very top of the stepladder) unless there is a suitable handhold. - - Ensure any locking devices are engaged. - - Try to position the stepladder to face the work activity and not side on. However, there are occasions when a risk assessment may show it is safer to work side on, e.g., in a retail stock room when you can’t engage the stepladder locks to work face on because of space restraints in narrow aisles, but you can fully lock it to work side on. - - Try to avoid work that imposes a side loading, such as side-on drilling through solid August 2019 Volume 25 I Number 6 www.plumbingafrica.co.za
