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

4 Suspension Systems Transportable outriggers Davits, groundor roof-rigged systems Carriages for horizontal movement

5 Stabilization Systems 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 Requirements: Platform Installation 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

9 Platform Safety Features 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

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

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

15 Annual Inspections 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

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

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

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 Overload platforms Work on platform with a slippery floor Carry flammable liquids on platforms Operate platform in bad weather DO Protect platforms from corrosives or heatproducing 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

22 Emergency Plans 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 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
