  2. Ladders

  3. General Ladder Requirements Ladders must be kept in a safe condition -- DO – Keep the area around the top and bottom of a ladder clear Ensure rungs, cleats, and steps are level and uniformly spaced Ensure rungs are spaced 10 to 14 inches apart Keep ladders free from slipping hazards

  4. General Ladder Requirements Use ladders only for their designed purpose -- DON’T – Tie ladders together to make longer sections, unless designed for such use Use single rail ladders Load ladders beyond the maximum load for which they were built, nor beyond the manufacturer’s rated capacity

  5. Securing Ladders This ladder is not on a stable surface • Secure ladders to prevent accidental movement due to workplace activity • Only use ladders on stable and level surfaces, unless secured • Do not use ladders on slippery surfaces unless secured or provided with slip-resistant feet

  6. Portable Ladders Inspect before use for cracks, dents, and missing rungs Design or treat rungs to minimize slipping Side rails -- at least 11 1/2 inches apart Must support 4 times the maximum load

  7. Painting Wood Ladders Don’t paint ladders Don’t use an opaque covering (like varnish) on a wood ladder

  8. Ladder Angle Non-self-supporting ladders: (which lean against a wall or other support) • Position at an angle where the horizontal distance from the top support to the foot of the ladder is 1/4 the working length of the ladder

  9. Ladder Rail Extension When using a portable ladder for access to an upper landing surface, the side rails must extend at least 3 feet above the upper landing surface

  10. Tall Fixed Ladder Requirements Equip a fixed ladder 24 feet or longer with either a: Ladder safety device Self-retracting lifelines with rest platforms every 150 feet or less Cage or well, and multiple ladder sections, each section not exceeding 50 feet

  11. Top Step Do not use the top or top step of a stepladder as a step

  12. Damaged or Defective Ladders A competent person must inspect ladders for visible defects, like broken or missing rungs If a defective ladder is found, immediately mark it defective or tag it "Do Not Use” Withdraw defective ladders from service until repaired Missing rung

  13. Climbing the Ladder Face the ladder when going up or down Use at least one hand to grab the ladder when going up or down Do not carry any object or load that could cause you to lose balance

  14. Near Energized Electrical Equipment If using ladders where the employee or the ladder could contact exposed energized electrical equipment, they must have nonconductive siderails such as wood or fiberglass. This is an unsafe condition

  15. Overhead Power Lines • Most overhead power line electrocutions are a result from a failure to maintain proper safe distance. • OSHA mandates that all activities, equipment and workers maintain at least a 10 feet distance from a power line

  16. Water and Electricity • In Green industries, water usage is common on a work site. • Water decreases resistance to electricity • Wet hand decreases the body’s resistance to shock • Keep electrical equipment and cords away from water • Never operate electrical equipment when standing in water

  17. Contact With Power Lines • Indirect contact occurs when the machine, tool, or object someone is holding contacts a line and transfers the energy to the person.

  18. Fatal Fact • An employee was trimming a tree that was near an overhead power line. The employee misjudged the distance, cut the branch, and it fell on the line. The employee, who was still holding onto the branch, was electrocuted. What could have been done differently?

  19. Activities Around Power Lines • Power line contact can result from: • Working in trees • Pruning trees from the ground • Using long pruning tools made of metal is dangerous • Raising or moving ladders • Raising or lowering machines • Moving irrigation pipes • Pulling or installing pump casing and pipe

  20. Staying Safe Around Power Lines • Always look up for overhead power lines • Always assume a power line is energized • Non-metallics like lumber, branches, and rope can conduct electricity • Use a ground worker to observe clearance • Stay at least 10 feet away • Don’t use ladders near overhead power lines • Plan travel routes for equipment

  21. Contact With a Power Line • If a co-worker contacts a power line: • Do not go near them if they are still in contact • Call the power company to de-energize the line • Call emergency services immediately

  22. Personal Protective Equipment • Proper foot protection (not tennis shoes) • Rubber insulating gloves, hoods, sleeves, matting, and blankets • Hard hat (insulated - nonconductive)

  23. Falls • Workers in elevated locations who experience electric shock may fall as a result of the shock. • Trees • Ladders • Aerial lifts

  24. Aerial Lifts

  25. Aerial Lifts • Preoperational inspection • Look for broken, missing, damaged or loose parts • Check pivot pins/retaining devises • Perform maintenance procedures required by manufacturer • Look for structural damage, cracked welds • Inspect hydraulic system

  26. Lift controls tested daily Only authorized persons to operate Never tie off to object outside the basket Harness and lanyard required Feet kept firmly on the floor of the basket No planks or ladders used for work position Never exceed basket weight limits Lift trucks not to be moved w/ basket elevated Upper and Lower controls Lower controls for emergency Aerial Lifts

  27. Contact With a Power Line • If you are in a vehicle in contact with a line: • Stay in the vehicle • Make sure no one comes near the vehicle • Call for help and contact the power company

  28. Contact With a Power Line • If you must exit the vehicle because of fire: • Jump to the ground and keep your balance • Do not touch anything with your hands • Hop away from vehicle with both feet together • If you can’t hop, shuffle your feet keeping both on the ground

  29. Summary • Inspect Ladders before use • Use ladders as manufacturers intended • Avoid contact with overhead wires if you are working with long objects • Ladders, pruning shears, pruning saws, aerial lifts • Maintain aerial lift per operators manual • Operate aerial lift as manufacturer intended • Keep electrical equipment away from water
