Mobile Elevated Work Platform (MEWP) (1).pptx
- 1. 1 SAFE Mobile Elevated WorkPlatform (MEWP) OPERATION AMERICAN INTERNATIONAL TRAINING SERVICES Abu Dhabi, UAE
- 2. -Aerial Work Platforms -ScissorLifts -Booms -Push Around Vertical (PAV) -Man Lift -Stick Boom Lifts -Track Mounts MEWP’S
- 3. Always consider -Height reach -Groundconditions -Restrictions within area -Availability to recharge -The requirement to travel whilst elevated -The SWL that can be carried Selecting your MEWP
- 4. • Read andunderstand the manufacturer’s operating instructions and user’s safety rules • Understand all labels, warnings and instructions • Ensure all occupants of the MEWP wear appropriate personal safety equipment • Ensure you have received relevant training and familiarization Before Operating Any MEWP
- 5. Before use theMEWP shall be given a visual inspection including but not limited to the following: • Operating and emergency controls • Safety devices • Personal protective devices • Air, hydraulic, and fuel systems leaks • Cables and wiring harnesses • Loose or missing parts PRE- INSPECTION
- 6. • Placards, warnings,control markings, and operating manuals • Outriggers, stabilizers and other structures • Guardrail system • Other items specified by the manufacturer • Battery state and cells • Check wheels PRE- INSPECTION
- 7. MEWP Accident Causes •Fall from elevated level • Ejections from the lift platform • Electrical shock (electrocutions) • Tip-overs • Structural failure (e.g. using lift as a material crane)
- 8. MEWP Accident Causes •Entanglement hazards • Contact with protruding objects and/or overhead objects • Operating the lift in severe weather or low visibility conditions • Inexperienced, untrained operators and non familiarized • Misuse • Lack of maintenance
- 9. Always look outfor: • Pedestrians • Other vehicles • Holes • Manholes and drains • Slopes/ramps PLAN YOUR ROUTE
- 10. Always look outfor: • Debris • Weak flooring • Overhead obstructions • Electrical conductors • Wind and weather conditions • Trenches PLAN YOUR ROUTE
- 11. • Check overheadobstructions • Check for cables, pipes and support beams • Find out what is distributed in any of the pipes or cables • Check throughways, paths or roads • Check for buildings and their entrance/exit routes • Check fire exit routes • Make sure there is a rescue plan • Check the stability of the ground service • Always use loading mats or timber to increase ground surface • Never use as an earth point for tools etc. • Do not overload. If overload alarm sounds, retract the MEWP • SWL includes operators, tools and any additional equipment being carried • Any hazardous fumes PLAN YOUR WORK AREA:
- 12. • Learning orclimbing over scaffold guardrails could result in falling off the MEWP • Horseplay on a MEWP could have serious consequences • Ice, snow, rain and liquids on the platform could cause slips and possible falls • Never access another structure from MEWP • Slips or trips on equipment, tools, etc. Lack of fall protection puts workers in great danger. FALL HAZARDS:
- 13. Fall protection isnot mandatory for a scissor lift so always ensure you Do not lower or stand on guardrails Do not use a ladder or any other object to gain height Guard rails remain up FALL PREVENTION
- 14. • Articulating aeriallifts, which have a hinged boom, require additional fall protection due to the potential of being bounced out of the bucket. • Telescoping aerial lifts, that only go straight up and down, do not require additional protection Fall Protection Boom
- 15. Fall arrest systemsinclude: • Full-body harness • Lanyards • Rope grabs • Lifelines • Lifelines anchorage points • Riggings FALL ARREST SYSTEMS
- 16. • Know theapplication limits of the system being used (see manufacturer recommendations) • Proper anchoring and tie-off techniques -Never attach yourself to unstable anchors -Always anchor to the designated anchor point • Deceleration distance and elongation of lanyards -Make sure that the lanyard is not too long (include stretch distance) FALL ARREST SYSTEMS
- 17. • Tools, equipment,materials, hard hat, etc. can fall from work activities on platform, potentially injuring personnel below • Zone off work area with suitable barriers • Hardhat required for all users on, and persons working below MEWP • Place tools and other equipment or materials away from the edge of platform FALLING OBJECT HAZARDS
- 18. • Electricity hasthe power to shock, burn, cause fires, explosions and even kill. • Electrical hazards encountered on a MEWP’S can be from power tools and equipment • Misused or damaged extension cords • Contacting overhead power lines -Always stay at least 15 meters (50ft.) away fully extended from steel towers and 9 meters (30ft.) away from wooden poles. ELECTRICAL HAZARDS
- 19. If a fellowworker does come in contact with an energized power source, do not rush to assist them. Immediately call 999, try to shut of the main power source, and follow the directions of the operator ELECTRICAL HAZARDS
- 20. Wind is aconcern of any MEWP operator who operates outdoors. How does wind affect the lift? • Creates additional force on the platform • Wind can be different above roof levels • Additional force caused by the wind can cause the MEWP to tip over. WIND HAZARDS
- 21. Pinch points ona scissor lift is the potential for having a limb or other body part pinched or crushed in the scissor arms or between the top rail and overhead structure. These arms collapse down upon each other at multiple joint locations when the platform is lowered, all of which serve as entryways for potential injury. PINCH/CRUSHING HAZARDS:
- 22. NEVER put yourhands or feet under the platform of the scissor lift unless you need to perform maintenance. In which case, you will need to disconnect the power and insert safety bars, which prevent the platform from collapsing.
- 23. • Report allaccidents and near misses immediately • Perform an investigation as soon as an accident occurs • Lock off MEWP if damaged and seek engineers' advice. ACCIDENT REPORTING:
- 24. • Keep flamesand sparks away. • Wear protective apron, gloves, and goggles when working with batteries • Make sure that a properly functioning eyewash station is nearby • Connect charger AC plug to proper voltage source • Disconnect charger from power source • Normal charging will take 10-14 hours • Check cells and top up if necessary.
