| Step | Potential Hazard | Control |
|---|---|---|
| Assess work area | Uneven terrain, soft soils, traffic exposure, buried utilities | Walk site to identify hazards; set up MUTCD compliant work zone; mark utilities; choose stable paths for equipment |
| Inspect equipment (grader, reclaimer, mixer, rollers) | Hydraulic leaks, faulty brakes, broken cutting tools, defective sprayers | Conduct pre operation inspection; check cutting teeth, sprayers, water tanks, sensors, backup alarms, and lights |
| Don required PPE | Dust exposure, chemical burns, struck by hazards | Wear respirator if using lime or cement; use gloves, safety glasses, high visibility vest, and steel toe boots |
| Prepare work zone | Traffic entering work area, poor visibility | Place cones, signs, and barriers; assign lookout; ensure equipment has adequate spacing |
| Spread stabilizing agents (lime, cement, fly ash) | Airborne dust, chemical burns, respiratory hazards | Apply on calm days when possible; workers stay upwind; use proper spreader; minimize dust using water misting if appropriate |
| Blend stabilizer into soil | Flying debris, dust clouds, equipment striking workers | Keep ground crew clear of reclaimer or mixer; use slow steady passes; maintain communication via hand signals or radio |
| Add water to soil mix | Slips on wet surfaces, hose pressure, overspray | Apply water slowly; avoid creating slick surfaces; maintain good footing |
| Grade and shape stabilized soil | Struck by grader blade, uneven ground, equipment rollovers | Maintain separation between grader and ground crew; operate at slow controlled speeds; watch for soft spots |
| Compact stabilized area | Equipment backing hazards, rolling edges, ground instability | Use rollers at controlled speeds; keep personnel away from drum path; avoid operating roller on steep or unstable edges |
| Manage dust and exposure | Worker inhalation hazards, reduced visibility | Use water to suppress dust; stop operations if visibility drops; ensure respirators are worn when needed |
| Inspect soil stabilization quality | Slips, soft ground, hidden voids | Walk area carefully after compaction; probe for weak spots; stay clear of edges that might fail |
| Repair deficient areas | Additional dust exposure, contact with cementitious materials | Reapply stabilizer using same PPE; maintain safe work distances; recompact as required |
| Clean equipment and tools | Chemical residue, dust inhalation | Clean equipment in designated area; wear gloves and eye protection; avoid high pressure spraying of dry cement residue |
| Restore site | Loose debris, trip hazards | Remove excess materials, packaging, or stabilizer; smooth disturbed areas; ensure drainage is not blocked |
| Remove traffic control | Worker exposure to passing vehicles | Remove cones and signs in reverse order; maintain lookout; continue wearing high visibility PPE |
