Working Around Mobile Equipment
Overview
Mobile equipment creates dynamic hazards that change constantly as machinery moves throughout the worksite. Workers must remain vigilant and follow specific protocols when working near excavators, bulldozers, cranes, and other moving equipment.
Why This Is Important
Struck-by accidents involving mobile equipment are among the leading causes of construction fatalities. The combination of large machinery, limited visibility, and workers on foot creates a dangerous environment that requires constant awareness.
Heavy equipment operators have significant blind spots and may not see workers even when they’re relatively close. The noise of machinery can also prevent operators from hearing warning shouts or other audio signals.
Best Practices & Safety Tips
Make Eye Contact
Always establish eye contact with equipment operators before entering their work area. If you can't see the operator, they likely can't see you.
Use Communication Systems
Utilize radios, hand signals, or spotters to maintain communication with equipment operators when working nearby.
Understand Blind Spots
Learn the blind spots for each type of equipment you work around. These areas vary significantly between different machines.
Use Physical Barriers
Set up cones, barriers, or flagging to clearly define work zones and separate pedestrian areas from equipment operations.
Plan Escape Routes
Always know where you can quickly move to safety if equipment unexpectedly approaches your work area.
Wear High-Visibility Clothing
Bright, reflective clothing makes you more visible to operators, especially in low-light conditions or dusty environments.
Respect Swing Radius
Stay outside the swing radius of excavators and cranes. Never walk under suspended loads or within the equipment's range of motion.
Attend Pre-Work Meetings
Participate in daily planning meetings to understand equipment movements and coordinate work activities safely.
Additional Safety Measures
- Follow Lockout Procedures - When maintenance work requires entering equipment areas, ensure proper lockout/tagout procedures are followed.
- Be Alert to Backup Alarms - Pay attention to backup alarms and other warning devices that indicate equipment movement in your area.
- Maintain Safe Distances - Stay at least 10 feet away from operating equipment unless specifically authorized to work closer.
- Never Approach from Behind - Always approach equipment from the front where the operator can see you.
Discussion Questions
- What types of mobile equipment do we work around most frequently in our operations?
- How do we currently communicate with equipment operators during work activities?
- What near-miss incidents have occurred involving mobile equipment in our workplace?
- How can we improve visibility and awareness between operators and ground workers?
- What changes could we make to our work zones to better separate equipment and pedestrian areas?
Action Items
- Review and practice communication protocols with equipment operators
- Identify and mark equipment blind spots in work areas
- Ensure adequate supply of high-visibility clothing for all workers
- Establish clear work zone boundaries and escape routes

Takeaway: Working safely around mobile equipment requires constant vigilance, clear communication, and respect for the dangers these powerful machines present. Always assume that equipment operators cannot see you, and take responsibility for your own safety by staying alert and following established protocols.
