Revised: 01/31/2023 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 />- Bodily Injury/struck- by or property <br />damage <br />- Falling Tools or Equipment <br />- Slips/Trips/Falls <br />1. Mark site for USA/Coordinate Dig Alert, Conduct Geo physical <br />survey, review maps and/or "as-builts" prior to saw cutting. Stop <br />work and reevaluate if something is not understood or there's a <br />change in conditions. Do not over-cut concrete/asphalt. <br />2. Always don proper hearing protection when operating saw. All <br />employees will wear hearing protection when its over 85 dBA. If <br />sound levels reach 95 dBA, employees must double up on hearing <br />protection by wearing ear muffs. <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 saw <br />without a proper blade guard, keep blade guard down, do not <br />overcut, (blade can break into pieces and go airborne). <br />4. Use saw with OEM integrated water supply for dust suppression, <br />dry cutting is not permitted. Use engineering and work practice <br />control methods for the equipment and task that follow 1926.1153, <br />Table 1: <br />Use of integrated water delivery system that continuously feeds <br />water to the blade. <br />Operate and maintain tool in accordance with manufacturer’s <br />instructions to minimize dust emissions. If wet methods can not be <br />used, employees must wear half-masked with P-100 filters. <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 if <br />saw is questionable. <br />7. Keep hoses, cords and other items routed out of path. <br />8. Avoid long-term, repetitive cutting. Cutting while tired will cause <br />you to stand closer to the saw and increase your risk of being <br />struck. <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 run- <br />off. Protect liquid from entering storm drain catch basins or 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
