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 surface Not securing ladder correctly Standing on the top two steps of a stepladder Overreaching 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.

25 Extension Ladders 25

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 rails Stand erect Extend arms straight out Palms 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. Ladder Height (ft.) Maximum Reach (ft.)* Height to Gutter or Top Support Point+ 16 15 9 ft. max. 20 19 9-13 ft. 24 23 13-17 ft. 28 27 17-21 ft. 32 31 21-25 ft. 36 34 25-28 ft. 40 37 28-31 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.

32 Secure and Stabilize Ladders, cont.

33 Secure and Stabilize Ladders, cont.

34 Secure and Stabilize Ladders, cont.

35 Loose Soil The spikes, or spurs, on the ladder safety feet allow for the ladder to be set up safely on loose soil to prevent slipping.

36 Step Ladders 36

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.

40 Proper Height Stepladders
Choose a stepladder that is no more than 4ft. shorter than the height you want to Reach.

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.

42 Maintaining a Safe Position on a Ladder, cont.

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.

44 Ladder Inspection, cont.

45 Review the Safety Labels on the Ladder

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

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 #1 Improper 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.

121 Picture #2 Where do we begin?

122 Picture #3

123 Picture #4

124 Picture #5 This 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 #6 This 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 #7 This 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 #8 Although no one is using the ladder, the metal spreader is not in the fully opened position.

128 Picture #9 This extension ladder is properly secured at the top to prevent displacement. This is one of many ways to secure extension ladders.

129 Picture #10 This 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 #11 This pump jack scaffold has a few issues with it’s set up, not to mention the ladder off to the left. Pump Jack Scaffold The 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 Ladder The ladder is not set up at the proper angle, increasing the chances of the ladder slipping.
