what goes up… must come down portable ladder safety introduce yourself and explain who sdao is the type of learning environment you’d like to have etc. overview equipment types checks critical number set up ascending descending while in use safe practices when you have a task to complete it is very important that you stop to consider what type of ladder would be appropriate to enable you to safely complete the task at hand. equipment types there are a wide variety of ladder types. basic step ladder trestle ladders extension ladders step ladders orchard ladder platform ladders etc. it’s important that you choose a ladder that will allow you to safely complete the task at hand. there are four different factors you should take into consideration to do this… equipment types type style proper length duty rating special duty iaa – ۳۷۵ lbs. extra heavy duty ia – ۳ lbs. heavy duty i – ۲۵ lbs. medium duty ii – ۲۲۵ lbs. light duty iii – ۲ lbs. material we just discussed some of the types of ladders. lets discuss four things that should be taken into consideration when choosing the ladder. the type should be appropriate for the surface you’re working on and the surface you’re working off and leaning the ladder onto if needed. secondly it’s critical that the ladder is both long enough and short enough that it’s not a hazard. we’re going to talk in a minute about how far the ladder should extend beyond the surface it’s leaned onto if so. thirdly consider the weight capacity of the ladder. this is really important if you’re moving materials finally if you have options of what material the ladder is there are a few things to take into consideration. if there are electrical hazard an aluminum ladder should not be used. fiberglass ladders are often very heavy if they’re longer. equipment checks prior to each use replace steps showing ¼ surface is worn away never paint wooden ladders check feet to make sure they are securely attached clean and lubricate moving parts spreaders hinges locks pulleys replace worn labels and components never use ladders with broken components a general check that the ladder is in good working condition should be completed prior to every use. this includes scanning the entire structure for signs of wear or weakness. if the ladder is wooden rungs should be replaced if they’re showing more than ¼ step is worn off. labels are mandated by manufacturers so they should be replaced if they are worn off. critical numbers ۳ ft above the surface distance from structure ¼ height of the structure if the ladder you’re using is longer than ۳۶ ft it must over lap ۴ ft. unless is it longer then ۴۸ feet in which case it must overlap ۵ ft. critical numbers ۲ ft. height no less than ۵ ft. no less than ۳ ft. given a building’s height is ۲ ft how long far away from the building should its base be located no less than ۵ ft. how many feet should the ladder extend over the roof line what would change if the building were ۴ ft tall ladder should be out from base no less than ۱ ft… and assuming the ladder would have to be taller than ۴۸ ft the overlap would need to be ۵ ft. set up – extension ladders check for overhead hazards electrical lines etc. stable surface if leaning against surface should extend at least ۳ ft. beyond the surface height base of ladder ¼ of structure height from the base of the structure set up – extension ladders walk the ladder up closed no overhead hazards back the ladder’s legs up raise the fly section set up – extension ladder secure the ladder tie off hook top employee to hold ladder level base reiterate the ۳’ overlap rule here. if your ladder cannot protrude beyond the roofline then you are required to secure the top of the ladder to the structure. ladders should be safely secured… tying them together with rope is not likely an adequate solution. photo from scotland. set up – step ladders check for overhead hazards electrical lines etc. stable surface fully extend all supports braces etc. ascending descending always… maintain three points of contact keep your center of weight torso between the legs of the ladder use pulleys or a tool belt if you need to carry items with you belt buckle rule if you keep your belt buckle within the rails of the ladder you’re keeping your center of balance within the rails too. ascending descending fixed ladders must have cage wells or ladder safety system if height is greater than ۲۴’ but less than ۵ ’ or ۲۴’ above the ground could include body harness while in use never use the top two rungs one person per ladder same rule applies while using a ladder too – keep your torso between the rails. it appears this construction worker is safely extending himself beyond the ladder because he has fall protection his body harness is not actually anchored to anything  while in use if you can’t reach… move the ladder clowns are great at walking ladders. that doesn’t mean it’s safe or appropriate in the work place. besides you’ll feel like a clown if you fall off the ladder safe practices prohibit ladders from being propped on boxes barrels and other objects both rails should be equally supported ladders should never be moved while occupied face ladders while climbing and descending surfaces both on ladder and ground around the ladder should be free of oil and other slipping hazards or osha’s published a very useful list of additional safe practices that should be implemented in addition to the equipment inspection type and safe setup …
