13 OSHA: Scaffold and Ladder Citations Plastering Contractor fined $106,200 for exposing employees to fall hazards while working on a scaffold without using fall protection equipment.Roofing Contractor fined $61,800 following an OSHA inspection for exposing employees to fall hazards including the use of a ladder that did not extend 3 ft. beyond the landing surface.
14 OSHA Fall Protection Requirements Subpart L (g)Each employee on a scaffold more than 10’ (3.1M) above a lower level shall be protected from falling to a lower level.Subpart X – LaddersFall protection is not required for workers climbing or working on portable ladders.Subpart X – StairwaysStairways having four (4) or more risers or rising more than 30 inches must be equipped with at least on handrail; and one stairrail system along each unprotected side or edge.Inform participants that OSHA has various requirements that address providing fall protection for workers.The next slide addresses the requirements of Subpart M – Fall Protection.
15 OSHA Fall Protection Requirements cont. Subpart M (b)(13)Residential construction. Each employee engaged in residential construction activities 6’ or more above lower levels must be protected by conventional or alternative fall protection:Exemption: When the employer can demonstrate the protection is infeasible or creates a greater hazard the employer must develop an alternative fall protection plan.
18 How do you prevent falls from ladders and scaffolds? Implement a comprehensive safety program.Understand OSHA ladder and scaffold regulations.Train workers to identify hazards associated with ladder and scaffold use.Use safe work practices.
19 Section 2: Ladder and Stairway Safety INTRODUCE yourself; briefly speak to your related background. SAY welcome to NAHB-OSHA Fall Protection.Section 2: Ladder and Stairway Safety
20 Learning Objectives: Section 2 Determine the proper ladder to use based on weight capacity and height.Calculate the proper pitch of extension ladders for proper set-up, and identify how to secure and stabilize ladders.Identify how to maintain a safe position when using a ladder.Identify safety requirements for protecting stairways.
21 Common Ladder Hazards Improper set-up Portable ladders not 3 feet above landing surfaceNot securing ladder correctlyStanding on the top two steps of a stepladderOverreaching when working from a ladder
22 Choosing the Right Ladder Before stepping onto a ladder, think about these things:Duty rating of the ladder—what capacity can it hold?Height of the ladder—too short or too tall?Condition of the ladder and instructions unique to the ladder selected.
23 Proper Duty Rating/Capacity OSHA Requirement Ladders shall not be loaded beyond the maximum intended load for which they were built nor beyond their manufacturer's rated capacity.
24 Proper Duty Rating/Capacity, cont. Select a ladder with the proper duty rating for your weight and the materials you are handling.
26 Proper Ladder Set-up Consider placement and pitch of the ladder. Secure and stabilize the ladder.
27 Pitch Extension Ladders Extension ladders should be used at a 4 to 1 pitch (1.2 to .3 m).For every 4 ft. (1.2 m) in height, the bottom of the ladder should be 1 ft. (.3 m) away from the structure.Example:20 ft. (height) ÷ 4 ft. = 5 ft. pitch
28 Pitch Extension Ladders, cont. Setting up extension ladders properly can reduce slip and overload hazards. A quick and easy way to determine if an extension ladder is properly set up is to:Place toes against ladder side railsStand erectExtend arms straight outPalms of hands should touch top of rung at shoulder level
29 Proper Height Extension Ladders When accessing another level, the ladder must extend at least 3ft. (0.9m) above the landing to provide a hand hold for getting on and off the ladder.3 ft.
30 Proper Height for Extension Ladders, cont. Choose the right ladder for the height you need to reach.LadderHeight (ft.)MaximumReach (ft.)*Height to Gutter or Top Support Point+16159 ft. max.20199-13 ft.242313-17 ft.282717-21 ft.323121-25 ft.363425-28 ft.403728-31 ft.*Assume a 5 ft.-6 in. person with a vertical reach of 12 in.+Support points for extension ladders reflect section overlap, ladder angle, or 3-ft. extension above roof line
31 Secure and Stabilize Ladders Extension ladders should be secured at the top or bottom to prevent movement.The base of an extension ladder must be secured in place by using the safety feet on the ladder or other effective means.
37 Step Ladders Only use in the fully open position on firm level ground. Do not use a stepladder that is folded or in a leaning position.Never sit/stand on the top two rungs.Consider work height when selecting a stepladder.
38 Step Ladders, cont.Stepladders are designed for use in an opened-and-locked position.
39 Step Ladders, cont.Do NOT use a stepladder that is folded or in a leaning position.This worker is using a stepladder in the folded, leaning position. This represents improper use of a stepladder and could possibly lead to injuries from the ladder failing.
41 Maintain a Safe Position on Ladders Face the ladder when ascending or descending.Maintain three points of contact at all times.Keep your body centered on the ladder.Never let your belt buckle pass either siderail.
43 Ladder Inspections Ladders must be inspected before each use. Broken or weak ladders or ladders that are not stable must be marked or tagged as defective and taken out of service.Look for cracks and weak points.Competent person must periodically inspect ladders.
46 Additional Safe Work Practices: Ladders Extension ladders should not be separated to create two ladders.Keep the areas around the tops and bottoms of all ladders clear to prevent trip-and-fall hazards.Avoid setting ladders up in high traffic areas or barricade the area around ladder.
47 Additional Safe Work Practices: Ladders, cont. Ladders must be kept free of oil, grease, and other slipping hazards.Consider using a rope to raise/lower materials instead of carrying items while climbing a ladder.Do NOT use metal or aluminum ladders near exposed energized electrical equipment.47
49 Learning Objectives: Section 3 Identify general requirements for safely building and using scaffolds.Identify competent person responsibilities.How to access scaffolds safely.Determine proper fall protection including guardrails and personal fall arrest systems.Identify safety requirements applicable to specific types of scaffolds.

118 Section 4: Group Workshop INTRODUCE yourself; briefly speak to your related background. SAY welcome to NAHB-OSHA Fall Protection.Section 4: Group Workshop
119 Hazard Violation Workshop Students will review a series of photographs of ladders and scaffolds in use on a jobsite. The assignment is to identify the hazards in each photo and discuss the corrective action required to correct the hazard. (Note: Some of the photos are of correct safe work practices.) You Play OSHA!
120 Picture #1Improper scaffold base. Masonry blocks and bricks are not acceptable as scaffold. These materials may fail due to the weight of the scaffold, workers, and any materials resulting in a collapse.
124 Picture #5This scaffold is fully braced, and set up on a proper base (not clearly visible in photo). Is there any falling object protection in place? Toeboards are not installed at this point.
125 Picture #6This worker is positioned on the stepladder properly. His body is centered on the ladder while performing truss installation, and he is below the top two rungs.
126 Picture #7This worker could probably use a taller stepladder to reach his task. He is not using the top two steps/rungs, but he is using the back side of the ladder to increase his reach. The back side of a stepladder is not permitted for use unless designed for such use.
127 Picture #8Although no one is using the ladder, the metal spreader is not in the fully opened position.
128 Picture #9This extension ladder is properly secured at the top to prevent displacement. This is one of many ways to secure extension ladders.
129 Picture #10This ladder is not positioned properly. When extension ladders are being used to access another level, they must extend at least 3ft. beyond the landing surface to provide a handhold for getting on and off of the ladder.
130 Picture #11This pump jack scaffold has a few issues with it’s set up, not to mention the ladder off to the left.Pump Jack ScaffoldThe platform of the scaffold is greater than 10ft. in height, without guardrails in place.Poles are not secured to the structure at the base. Notice the angle of the pole on the right.Mudsills are not in place.Extension LadderThe ladder is not set up at the proper angle, increasing the chances of the ladder slipping.
