Confirm that(if applicable)"Call Before You Dig"and Damage to underground utility; confirm positive responses from local utility companies property damage; personal injury prior to subsurface work in order to confirm utility mark outs. Must have a case#before digging. 1a. Review pre-clearing checklist form and sub-surface clearance form. Pre-clearing protocol indicates that clearance must be conducted to a minimum of 5 vertical 1 b. FALL: feet below ground using hand tools. Slip, Trip or Fall may cause 1 b. Be aware of the conditions when walking or loading muscle strains or tears, abrasions, equipment and working. Walk within established pathway lacerations, or broken bones. avoiding uneven surfaces. Remove potential slip/trip/fall hazards. 2. Mobilize/demobilize and 2a. See Mobilization/Demobilization 2a. See Mobilization/Demobilization JSA establish work area JSA 3. Concrete/asphalt removal 3a. CONTACT: Flying debris striking 3a. Maintain 10'exclusion zone.

Use anti-whip devices on compressor hoses. air knife and water lance 3a. Wear a face shield to protect face from flying debris when using air knife or water lance. 3a. Utilize a traffic cone or shield over the hole during air knife activities to keep flying debris close to ground. 3b. EXPOSURE: Inhalation/exposure 3b. Monitor breathing zone with a calibrated PID and multi- to hazardous vapors and/or gas meter. If vapors sustain levels>5 ppm,the Roux concrete dust field personnel must temporarily cease work, instruct all Site personnel to step away from the area of elevated readings and inform the Roux Project Manager of the condition. The Roux Project Manager will then recommend additional precautions. 3b. Wet concrete while using saw to minimize dust and wear dust mask to prevent inhalation. 3b.

' Each Job or Operation consists of a set of tasks/steps. Be sure to list all the steps needed to perform job. ' A hazard is a potential danger. Break hazards into five types: Contact-victim is struck by or strikes an object; Caught-victim is caught on,caught in or caught between objects;Fall-victim falls to ground or lower level(includes slips and trips);Exertion-excessive strain or stress/ergonomics/lifting techniques;Exposure-inhalation/skin hazards,energy source;Energy Source—electricity,pressure,compression/tension. Using the first two columns as a guide,decide what actions or procedures are necessary to eliminate or minimize the risk. List the recommended safe operating procedures. Say exactly what needs to be done-such as"use two persons to lift". Avoid general statements such as,"be careful'. � ROUX �
