Choosing Right Equipment -- Ladder or Scaffold?

Ladder

  • Will the job take only a short amount of time?
  • Does work require side-to-side movement?

Types of Ladders

US&A (v. 2/07)

duty ratings
Duty Ratings
  • Type IAA: Special-duty -- 375 lbs
  • Type IA: Extra heavy-duty -- 300 lbs
  • Type I: Heavy-duty -- 250 lbs
  • Type II: Medium-Duty -- 225 lbs (not recommended at UWM)
  • Type III: Light-Duty -- 200 lbs (not allowed at UWM)

US&A (v. 2/07)

load limits
Load Limits
  • Select 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.

Ladder Safety Checklist

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.

US&A (v. 2/07)

immediately remove ladder from service if inspection finds
Immediately remove ladder from service if inspection finds
  • Broken or missing steps, rungs or cleats
  • Broken or damaged side rails
  • Other faulty equipment such as missing feet, damaged connections, broken rivets

US&A (v. 2/07)

slide11

Ladder Set-Up

  • Always place ladders on a stable surface
  • Clear debris
  • Level uneven ground

US&A (v. 2/07)

slide12

Ladder Set-Up

  • Always assure secure footing
  • Keep ladder free from mud, grease and other substances which could cause you to slip
  • Keep area around ladder free from traffic.

US&A (v. 2/07)

slide13

Ladder Set-Up

  • Always lock or guard door if ladder blocks doorway

US&A (v. 2/07)

slide14

Ladder Set-Up

  • Base of straight ladder should be 1 foot away from the surface for every 4 feet to the top

(1:4)

4 feet

1 foot

US&A (v. 2/07)

slide15

Ladder Set-Up

  • Don’t place ladder on boxes, barrels or other unstable surfaces to extend height

US&A (v. 2/07)

extension ladders
Extension Ladders
  • Always raise extension ladders so that the upper section overlaps and rests on the bottom section.
  • The upper section must always overlap on the climbing side of the extension ladder.

US&A (v. 2/07)

extension ladder overlap
Extension Ladder Overlap

Extension Ladders should have the proper overlap:

  • Three foot overlap for 32-foot ladder
  • Four foot overlap for 32- to 36-foot ladder
  • Five foot overlap for 36- to 48-foot ladder
  • Six foot overlap for 48-foot ladder

US&A (v. 2/07)

straight ladder
Straight Ladder
  • If a straight ladder is used to climb onto an elevated work station, it will extend at least 3 1/2 feet above the working level.

This ladder is not sufficiently extended

US&A (v. 2/07)

slide19

Safe Ladder Use

  • Face the ladder when ascending or descending
  • Both hands should be placed on ladder rails, not on rungs, when ascending and descending
  • Maintain 3 point contact at all times -- This means both feet and one hand or one foot and both hands

US&A (v. 2/07)

slide20

Safe Ladder Use

  • Use extra caution while climbing in windy weather

US&A (v. 2/07)

slide21

SafeLadder Use

  • Always climb completely past the landing before stepping over

US&A (v. 2/07)

slide22

SafeLadder Use

  • Don’t“walk” a ladder (rocking from side to side to move)
  • Don’t use a stepladder as a straight ladder

US&A (v. 2/07)

slide23

Safe Ladder Use

  • Don’t carry tools in your hands. (A tool pouch or belt should be used or tools should be hoisted up)
  • Don’t overreach to either side or lean too far forward or backward

US&A (v. 2/07)

slide24

Safe Ladder Use

  • Don’t use a ladder without locking spreader or other device in place

US&A (v. 2/07)

slide25

Safe Ladder Use

  • Don’t climb using bracing on back legs of step ladder
  • Don’t attempt to straighten or use a bent ladder made of metal or reinforced plastic--repairs should be made by qualified personnel

US&A (v. 2/07)

slide26

Safe Ladder Use

  • Don’t Climb using two highest steps or top of platform

US&A (v. 2/07)

slide27

Safe Ladder Use

  • Don’t use a defective ladder
  • Don’t block a fire exit
  • Don’t use a ladder as a platform
  • Don’t use a ladder by more than one person

US&A (v. 2/07)

slide28

Safe Ladder Use

  • Don’t use a ladder if you are feeling dizzy, light-headed, are excessively tired, on medication, have recently consumed alcohol or are otherwise temporarily impaired.

US&A (v. 2/07)

slide29

Ascending and Descending

  • Always face ladder when ascending, descending and performing work

US&A (v. 2/07)

slide30

Safe Ladder Use

  • Keep between the side rails when working --your body should be centered on the ladder so your belt buckle is between the side rails

US&A (v. 2/07)

slide31

Ladder Storage

  • Store ladders for easy access and inspection.
  • Store vertically if possible. If not possible, store horizontally supporting ladder at several points to avoid sagging
  • Protect ladder from heat, weather and corrosive materials

US&A (v. 2/07)

slide32

Ladder Storage

  • Do not leave ladders where they may create a tripping or fall hazard for others

US&A (v. 2/07)

slide33

Lifting and Carrying

  • Lift ladder using legs muscles, not back
  • Carry holding ladder close to body

US&A (v. 2/07)

slide34

Lifting and Carrying

When carrying ladder:

  • Balance center of ladder on your shoulder
  • Position so front end of ladder is above your head and back end is near the ground

US&A (v. 2/07)

slide35

Lifting and Carrying

When ascending and descending stairs, carry ladder with one hand and hold stair rail with the other hand

US&A (v. 2/07)

slide36

Lifting and Carrying

  • Set ladder down when opening and closing doors
  • Take special care when negotiating corners or turning around

US&A (v. 2/07)

slide37

Lifting and Carrying

  • When it is necessary for two people to carry a ladder, both should be on the same side of ladder and both people should walk in step.
  • Spikes, hooks or ladder feet should face toward the rear when ladder is being carried

US&A (v. 2/07)

what s wrong in this picture1
What’s Wrong in this Picture?
  • Climb only as high as the 2nd tread from the top on a step ladder and the 3rd rung from the top on a straight ladder.

US&A (v. 2/07)

what s wrong in this picture2
What’s Wrong in this Picture?
  • Do not sit on the ladder and never sit or stand on the top cap of a step ladder – it is not designed to carry your weight.

US&A (v. 2/07)

slide41

What’s Wrong in This Picture?

Ladder should be opened fully and locking mechanism engaged prior to ascending
