Safety Features Do you understand: Suspension and stabilization systems? Hoisting machines? Platform installations? Load capacity and design? Platform safety features?
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
Annual Inspections Building support structures All platform components Hoist control systems Parts subject to wear
Wire Suspension Rope Inspections Distortion, such as kinks Evidence of heat damage Deterioration from corrosion Noticeable rusting or pitting More than one broken wire
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
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
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
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
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
Emergency Plans Written plan and employee training Emergency electrical operating device Rescue operations Communications
Emergency Plans (cont.) Emergency alarms Emergency escape routes
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.
Safety Procedures Do you understand: Inspection requirements and procedures? Proper use of personal fall arrest systems? Safe work practices? Emergency procedures?
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
