  1. Powered Platform Safety

  2. Session Objectives • You will be able to: Identify powered platform components Recognize platform safety features Understand inspection requirements Use personal fall arrest systems properly Follow safe work practices Act effectively in an emergency

  3. Building Owner Certification • Equipment must meet OSHA design safety criteria • Equipment must be tested, inspected, and maintained • Equipment must be certified by owner • Equipment must meet OSHA design safety criteria • Equipment must be tested, inspected, and maintained • Equipment must be certified by owner

  4. Suspension Systems • Transportable outriggers • Davits, ground- or roof-rigged systems • Carriages for horizontal movement

  5. Stabilization Systems • Continuous • Intermittent • Button guided • Angled roping • Alternative • Continuous • Intermittent • Button guided • Angled roping • Alternative

  6. Hoisting Machines • Hoisting machines must: • Have a primary brake • Have a secondary or emergency brake • Be able to handle 125% of rated load • Be able to stop overspeed descent • Have moving parts and pinch points guarded

  7. Platform Installation • Requirements: • Safe access for equipment maintenance • Protective perimeter guardrail • Dedicated, separate electrical power • Lockable power disconnect switch • Requirements: • Safe access for equipment maintenance • Protective perimeter guardrail • Dedicated, separate electrical power • Lockable power disconnect switch

  8. Load Capacity Design • Capable of 4 times maximum load • Hold 250 pounds per platform occupant • Withstand 50 mph winds • Connections able to handle vibration • Load rating plate visible • Capable of 4 times maximum load • Hold 250 pounds per platform occupant • Withstand 50 mph winds • Connections able to handle vibration • Load rating plate visible

  9. Platform Safety Features • 2 feet wide • Slip-resistant floors • Fire extinguisher • Tool and material storage • 2 feet wide • Slip-resistant floors • Fire extinguisher • Tool and material storage

  10. Platform Safety Features (cont.) • Operating controls on platform • Maximum rated speeds • Safety access ways • Vertical lifelines for each occupant • Operating controls on platform • Maximum rated speeds • Safety access ways • Vertical lifelines for each occupant

  11. Guardrails • Working platforms • Roofs and access ways • Top rails • Midrails • Toe board

  12. 1. What information is on the load rating plate? 2. Where are the emergency stops located? 3. How many vertical lifelines must be provided on a platform? Safety Features: Multiple Choice a. Manufacturer information b. Load limit c. Type of fuel used a. At either end of the platform b. Floor of platform c. On the rails a. Maximum of four b. One for each workeron the platform c. At least two

  13. Safety Features • Do you understand: • Suspension and stabilization systems? • Hoisting machines? • Platform installations? • Load capacity and design? • Platform safety features?

  14. Equipment Inspections • Inspection by a competent person • Daily visual inspection • Monthly maintenance and wire rope inspection • Thorough annual inspection • Inspection of system after any incident • Certified records • Inspection by a competent person • Daily visual inspection • Monthly maintenance and wire rope inspection • Thorough annual inspection • Inspection of system after any incident • Certified records

  15. Annual Inspections • Building support structures • All platform components • Hoist control systems • Parts subject to wear • Building support structures • All platform components • Hoist control systems • Parts subject to wear

  16. Wire Suspension Rope Inspections • Distortion, such as kinks • Evidence of heat damage • Deterioration from corrosion • Noticeable rusting or pitting • More than one broken wire • Distortion, such as kinks • Evidence of heat damage • Deterioration from corrosion • Noticeable rusting or pitting • More than one broken wire

  17. Daily Inspections • Learn to identify key safety elements • Report any damage • Inspect governors and secondary brakes • Perform a hoist test • Test controls and emergency stops • Look for visible defects • Learn to identify key safety elements • Report any damage • Inspect governors and secondary brakes • Perform a hoist test • Test controls and emergency stops • Look for visible defects

  18. Personal Fall Arrest Systems • Wear when on or around powered platforms • Attach lanyard to center of back • Use one lifeline per worker • Properly tie off • Check potential fall path • Wear when on or around powered platforms • Attach lanyard to center of back • Use one lifeline per worker • Properly tie off • Check potential fall path

  19. Personal Fall Arrest Systems (cont.) • Protect lanyards from damage • Inspect daily • Do not use defective equipment • Know how to use your personal fall arrest system • Understand rescue procedures

  20. Safe Work Practices DON’T DO • Overload platforms • Work on platform with a slippery floor • Carry flammable liquids on platforms • Operate platform in bad weather Protect platforms from corrosives or heat-producing processes

  21. Safe Work Practices (cont.) • Mount a wind-measuring anemometer to platform • Don’t let tools, materials, debris accumulate • Keep stabilizer ties untangled • Maintain voice communication • Lock power disconnect “on” • Mount a wind-measuring anemometer to platform • Don’t let tools, materials, debris accumulate • Keep stabilizer ties untangled • Maintain voice communication • Lock power disconnect “on”

  22. Emergency Plans • Written plan and employee training • Emergency electrical operating device • Rescue operations • Communications • Written plan and employee training • Emergency electrical operating device • Rescue operations • Communications

  23. Emergency Plans (cont.) • Emergency alarms • Emergency escape routes

  24. Safety Procedures: True or False? • Platforms need only be inspected once a year. • You shouldn’t work on a platform with a slippery floor. • It’s safe to carry flammable liquids on platforms if there’s a fire extinguisher. • You should maintain voice communication with someone in the building while working on a powered platform.

  25. Safety Procedures • Do you understand: • Inspection requirements and procedures? • Proper use of personal fall arrest systems? • Safe work practices? • Emergency procedures?

  26. Key Points to Remember • Learn about powered platform hazards and safety features • Inspect equipment before each use • Follow safe work practices • Use the personal fall arrest system • Learn emergency procedures
