Mobile cranes on NYC construction sites operate in tight urban spaces with workers, pedestrians, and other equipment all in close proximity. The swing radius of a crane counterweight and the fall zone beneath a suspended load are not places workers belong — ever. Being struck by a crane is consistently in the top causes of construction fatalities in New York City.

• No worker inside the swing radius when the crane is operating — this includes the counterweight radius, not just the boom radius
• No one under a suspended load — ever. Load must be traveled over a protected, barricaded path
• No walking under the boom even when no load is attached — a boom failure can and does happen without a load
• Proximity to energized lines: 20-foot minimum between any crane component and overhead power lines — 50 feet for lines > 350kV

• Know the swing radius of the crane operating on your site today — the GC should mark it or post the information
• Make eye contact with the crane operator's designated spotter before crossing any zone near the crane
• Never assume the operator sees you — crane operators have significant blind spots, especially to the rear and below the hook
• If the lift plan shows a load traveling over your work area: your work area moves. No exceptions
