Critical Safety Procedures
Follow these step-by-step procedures for key safety aspects of concrete pump truck operation.
Power Line Safety Protocol
- Survey site for overhead power lines before positioning pump truck
- Identify voltage level of power lines if possible
- Maintain minimum 20-foot clearance for all power lines
- Increase clearance to 50+ feet for lines over 350kV
- Position dedicated power line spotter with radio communication
- Mark safe operating zones with cones, flags, or tape
- Maintain continuous communication with spotter during operation
- Stop operations if clearance cannot be maintained
- Create written power line safety plan if working near lines
- Train all personnel on electrical hazards and emergency procedures
Outrigger Setup Protocol
- Assess ground conditions for adequate bearing capacity
- Calculate required area of support based on ground conditions
- Place outrigger pads on level, compacted surface
- Ensure pads are properly sized (min. 3x area of outrigger foot)
- Use properly constructed cribbing on soft or uneven ground
- Stack cribbing in alternating layers for stability
- Fully extend all outriggers to maximum width
- Raise truck to level position using outrigger controls
- Verify level with bubble levels in multiple directions
- Recheck outrigger setup throughout operation for sinking
Blockage Clearing Protocol
- Stop pumping immediately if blockage is suspected
- Shift pump into reverse to relieve pressure
- Switch off pump and engine
- Communicate blockage to all personnel in work area
- Establish exclusion zone around pipeline system
- Don appropriate PPE (face shield, gloves, protective clothing)
- Confirm pressure is relieved before dismantling pipeline
- Disconnect pipeline only at clamps, never at blockage point
- Direct pipe away from personnel when disconnecting
- Report and document all blockage incidents for review
Clean-Out Safety Protocol
- Establish containment area for concrete washout
- Ensure EPA/local compliance for concrete waste disposal
- Notify all personnel that clean-out is beginning
- Remove end hose and install clean-out catcher
- Insert appropriately sized sponge ball into system
- Maintain exclusion zone around discharge end
- Start pump at slow speed for clean-out process
- Never look directly into end of pressurized pipe
- Continue water flow until discharge runs clear
- Confirm retrieval of clean-out ball before disassembly
