12 Aug Dump Truck Operation – JSA

Dump Truck Operation Job Safety Analysis (JSA)

Job / Task

Inspection, startup, travel, backing, positioning, loading, hauling, dumping, spreading material, parking, and shutdown of dump trucks used for construction, excavation, hauling, and material-delivery operations.

Purpose

This Job Safety Analysis (JSA), also known as a Job Hazard Analysis (JHA), identifies hazards associated with dump truck operation and establishes controls to prevent struck-by, caught-between, collision, rollover, tip-over, overhead electrical contact, uncontrolled dumping, falling-material, and equipment-failure incidents.

Personnel Qualifications

Dump trucks shall be operated only by properly licensed, trained, competent, and authorized drivers who are familiar with the specific vehicle, manufacturer instructions, controls, warning devices, rated capacities, inspection requirements, dumping procedures, and applicable site traffic rules.

Drivers shall:

• Possess the appropriate driver’s license or commercial driver’s license when required.
• Complete required vehicle and site-specific training before operation.
• Perform required pre-trip and pre-use inspections and report defects.
• Understand vehicle blind spots, turning radius, stopping distance, backing hazards, and raised-bed clearance.
• Wear the seat belt whenever the vehicle is in motion.
• Know the truck’s rated capacity and never knowingly exceed allowable load limits.
• Use a spotter when visibility is restricted or site conditions require one.
• Recognize overhead power-line, unstable-ground, slope, edge, traffic, and pedestrian hazards.
• Ensure personnel remain clear of the truck during loading, backing, and dumping.
• Stop operation whenever vehicle condition, visibility, ground stability, or site conditions become unsafe.

Required PPE

PPE shall be selected based on the task and work environment and may include:
