Injurious Contact with Heavy EquipmentPART ONE
Guadalupe Restoration Project
Injurious Contact• 1 in 4 work related fatalities in U.S. are from
accidents involving vehicles or heavy equipment
• 11 near-miss incidents July 2007 at GRP were related to potential injurious contact
• On-site heavy equipment:– Excavators– Off-road dump trucks– Haul trucks– Sheetpile Driver– Bull dozer, Loaders, Water Trucks– Backhoe
Potential Injuries
• Struck by excavator/backhoe bucket• Run over by heavy equipment, off-
road vehicles, haul trucks, excavators• Crushed/Pinch injuries between
rotating and pivoting equipment
Common Causes
• Non-communication• Poor visibility• Lack of Knowledge• Not taking time or making effort to follow
proper procedures and safe work practices
Working Safely Near Heavy Equipment
Location, Location, Location
• Where would you stand next to heavy equipment
• How close would you stand to heavy equipment

How do we mitigate injurious contact with heavy equipment?
Focus on Safety Radius and Blind Spots
• Safety Zones Vary with equipment and activity
• Excavators – 30-foot radius• Sheetpile Driver – 100-foot radius• Bull Dozers/Backhoes – 30-foot radius• Stay out of blind spots!
Additional Mitigation Measures• Knowledge of where heavy equipment will
be working, when work is happening and WHO is in charge of work area
• Establish eye contact with operator/driver• Use pre-established hand signals or radio• ONLY approach when equipment is at
ZERO energy (turned off, bucket on ground)
• FOLLOW JSA Critical Actions
How do we implement these?
• Perform SPSA at work site before work and throughout the task
• Daily JSAP discussion should include specific where, when details of operation and who points of contact are
• Communicate site-specific hazards and mitigation measures to others before they enter your work area
• Communicate with HIGHER risk personnel: SSEs, new or infrequent subcontractors, and visitors
New Perspective
• Think from perspective of heavy equipment operator or driver
• Respect safety zone - know safe distance• Position yourself in operator’s or driver’s
field of view
