2 US&A (v. 2/07) 2 Choosing Right Equipment -- Ladder or Scaffold? Will the job take only a short amount of time?Will the job take only a short amount of time? Does work require side-to-side movement?Does work require side-to-side movement? Does the work require using tools with both hands?Does the work require using tools with both hands? Ladder Scaffold

3 US&A (v. 2/07) 3 Straight LadderStraight Ladder Step LadderStep Ladder Extension LadderExtension Ladder Sectional LadderSectional Ladder Trestle LadderTrestle Ladder Trolley LadderTrolley Ladder Side RollingSide Rolling Mason’s LadderMason’s Ladder Max 30’Max 30’ Max 20’Max 20’ Max 60’Max 60’ Combined lengths of section not longer t han specified for equivalent non-sectional typesCombined lengths of section not longer t han specified for equivalent non-sectional types Max 30’Max 30’ Max 20’Max 20’ Max 40’Max 40’ Types of Ladders

4 US&A (v. 2/07) 4 Duty Ratings Type IAA: Special-duty lbs Type IA: Extra heavy-duty lbs Type I: Heavy-duty lbs Type II: Medium-Duty lbs (not recommended at UWM) Type III: Light-Duty lbs (not allowed at UWM)

5 US&A (v. 2/07) 5 Load Limits Select a ladder designed to hold the necessary load, including worker and equipmentSelect a ladder designed to hold the necessary load, including worker and equipment Do not assume that a longer ladder has a higher duty rating. There is no relationship between length and duty rating. The American National Standards Institute (ANSI) requires that a duty rating sticker be placed on the side of every ladder so users can determine if they have the correct type ladder for each task/job.American National Standards Institute

6 US&A (v. 2/07) 6 Advantages/Disadvantages FiberglassFiberglass –Strong, lightweight, electrically non- conductive –More expensive than wood or metal Fiberglass Ladder

9 US&A (v. 2/07) 9 Fixed Ladders Prior to ascending or descending a fixed ladder, examine connections to assure that ladder is properly secured Fixed ladders are located in the Fine Arts Complex -- Theatre and Recital Hall

10 US&A (v. 2/07) 10 Check for damage prior to using: Make sure feet are not broken or malfunctioning and that the slip- resistant pads are secure. Inspect for cracks, bends & splits on the side rails, rungs & steps. Make sure both rung locks are working properly. Test the rope & pulley. Examine rope for any signs of fraying. Make sure the pulley is operating smoothly. Ensure all bolts and rivets are secure. Make sure ladder is free of foreign materials such as oil & grease. Make sure the spreader braces are secure & working properly. Aluminum or steel ladders should be inspected for rough burrs and sharp edges. Ladder Safety Checklist
