Work Equipment,Machinery and Tools Safety
- 1. MODULE 10-WORK EQUIPMENT, MACHINERY AND TOOLS SAFE COMPANY
- 2. POWERED TOOLS AND MACHINERY A machine operator is exposed to risks! General preventive measures: Training and have sufficient experience Not wearing loose-fitting clothes or jewelry and long hair Necessary PPE Floor clean, smooth and dry Freedom of movement around the machine Adequate lighting Machines checked regularly. Maintenance activities: machine shut down (See slides 12 and 13)
- 3. SIMPLE HAND TOOLS Types of simple hand tools: • Powered by human strength alone • Causes: improper use and bad maintenance • Risks: cuts, bruises, grazes and dislocations of the hand and wrist • Preventive measures: good maintenance and cleaning, not using damaged tools (daily pre-use check) and only using the tools for their intended purpose, adequate PPE if necessary • Hammer, spanner, file, chisel, screwdriver, pliers: special preventive measures
- 4. BLIND FLANGES Concept: round metal plate that´s inserted between the flange connection of the pipeline. Preventive measures: seals off the pipeline. Always adhere to the instructions and procedures imposed by the owner of the installation.
- 5. FIXED MACHINES Risks; rotating cutting tools, flying dust, high noise levels, inadvertent start-up of the machine. Operator training (some countries 18 years old) Preventive measures: red emergency button, sufficient freedom of movement to bring in and remove the work pieces. Never do interventions with the hands on a running machine. No hands to remove sawdust and wood shavings. Wear close-fitting clothes and avoid jewelry.
- 6. POWERED AND ELECTRICAL HAND TOOLS Powered hand tools are well designed and adapted to the nature of the work, properly maintained and safely stored. • Portable hand tools must always be equipped with a dead man´s switch. • Electrical hand tools: inspected frequently and well-maintained. Safe operating voltage. If possible: double insulation (do not earth). • Cables must not traverse gangways or scaffolds. Do not exceed the maximum capacity of reels. Only explosion-proof tools in spaces with risks of explosion.
- 7. PNEUMATIC HAND TOOLS Inspected frequently and well-maintained Equipped with a dead man´s switch Wear the necessary PPE Take frequent breaks from operations involving strong vibrations. Cut off the air supply to the equipment.
- 8. DRILLS Properly clamped The drill spindle must be covered as far as possible and the protection must NEVER be removed Never change the setting of the drill while it´s still running Shavings must be removed with a brush Do not wear gloves and wear close-fitting clothes. Wear a hairnet to keep from getting caught. Wear safety glasses
- 9. GRINDERS Only properly trained personnel The grinding wheel: sufficiently round and not be clogged Grinding wheel and wheel guard: properly mounted Cover the sides of the machine Remove all flammable materials near the work area (fire extinguisher handy) Use the spark arrestors to protect yourself against sparks. Wear safety goggles and ear protection
- 10. PORTABLE GRINDERS Equipped with a dead man´s switch and a side handle and the grinding wheel must be protected by a wheel guard. Never exceed the maximum number of revolutions of the disc Do not put the portable grinder down until it has been switched off and the disc has come to a complete stop Clamp the work piece ALWAYS wear ear protection and safety goggles
- 11. CIRCULAR SAW Operators: at least 18 years of age and trained Large pieces: a second person or a roller conveyor Well adjusted guide rail and a push stick to move small or narrow pieces. Good dust extraction Never wear loose clothing or jewelry. Tie back long hair.
- 12. ISOLATION PROCESS Steps concerning isolation: • Notify the personnel involves • Identify energy sources • Use the normal controls. • Isolate the equipment • Install signs, labels or lockout devices (national legislation) • Check for hidden energy • Test all parts of the machine.
- 13. RESTART PROCESS Steps when restarting process: • Remove rubbish, tools and spares • Remove all personnel from the work area • Inform affected personnel about restarting • Remove signs, locks and tags
