Revised: 02/01/2023 3 <br />Job Steps Hazards Actions to Eliminate or Minimize Hazards RAC <br />4. Perform Saw Cutting of <br />Concrete/Asphalt <br />- Property damage to subsurface <br />structures <br />- Excessive Noise <br />- Bodily injury from flying debris <br />- Exposure to Silica dust <br />- Electric shock <br />- Losing control of saw <br />- Objects in path <br />- Vibration <br />- Exhaust inhalation hazard <br />- Run-off of water residue <br />- Explosion Hazard <br />- Silica Run-Off (Contamination) <br />- Alkali Burns to eyes or skin <br />1. Mark site for USA/Coordinate Dig Alert, Conduct Geo physical <br />survey, review maps and/or "as-built's" prior to saw cutting. <br />Stop work and reevaluate if something is not understood or <br />there's a change in conditions. Do not over-cut concrete/asphalt. <br />2. Always don proper hearing protection when operating saw. <br />3. Stay out of the line-of-fire and do not allow unnecessary <br />personnel within the exclusion zone. Always don a face shield in <br />addition to safety glass to protect eyes and face. Do not operate <br />saw without a proper blade guard, keep blade guard down, do <br />not over-cut, (blade can break into pieces and go airborne). <br />4. Use saw with OEM integrated water supply for dust <br />suppression, dry cutting is not permitted. <br />5. Electric saws should be approved, double-insulated. If not, it <br />should be properly grounded and plugged into a GFCI-protected <br />outlet. Cords should not be in water. <br />6. Keep a firm grip on saw at all times. STOP work immediately <br />if saw is questionable. <br />7. Keep hoses, cords and other items routed out of path. <br />8. Take regular breaks from cutting or switch with another <br />worker (if cutting for a prolonged period of time) to prevent <br />fatigue. <br />9. Never operate gas powered saw in a confined space. Use <br />ventilation fans at source of emissions to provide fresh air and <br />mitigate build fumes in or near the breathing zones. <br />10. Vacuum all water and store in proper drum(s) to prevent <br />run-off. Protect liquid from entering storm drain catch basins or <br />sewers. <br />11. Only refuel machine when saw is shut-off and cooled down. <br />12. Vacuum slurry from saw cuts. <br />13. Use adequate water while cutting and always wear the PPE <br />required for the task. Keep skin, eyes and face protected from <br />concrete slurry created during cutting. <br />M <br />NC-25-1137 Tiwana & Sons <br />1210 East Hammer Lane, Stockton, CA 95210
