Avoiding Major Hazards During Crane Lifts

Welcome back, let's Build Smart & Build Safe! We’ve covered the components and communication of crane operations. Today, we're focusing on the deadliest risks that can be avoided with proper planning and awareness: all the major hazards that can turn a lift into a tragedy.

While rigging and signaling are key, certain environmental factors and conditions pose an immediate and severe threat.

1. The Danger of Overhead Power Lines

This is one of the most common causes of crane-related fatalities. You don't have to touch a power line to be in danger. The electricity can arc to the crane, turning the entire machine into a conductor.

• Safety Rule: Always maintain a safe distance from all energized power lines, both overhead and underground. A minimum of 10 feet is required, but an even greater distance is always safer.

• The Plan: Survey the area before any lift and work with your utility company to identify and, if possible, de-energize lines or work with utility companies to install protective cover on the lines.

2. The Threat of Crush Zones

A crane's operation creates several "crush zones" that are incredibly dangerous.

• The Swing Radius: The area the crane's counterweight swings through can crush you against a wall, a pillar, or another piece of equipment. Always stay out of this area.

• The Suspended Load: This is a zero-tolerance zone. Never walk, stand, or work directly under a suspended load. If rigging fails, or if a sudden gust of wind causes the load to swing, you are in immediate danger.

3. Unstable Ground Conditions

A crane's stability is completely dependent on the ground beneath it.

• The Hazard: If the ground is not level, firm, and properly supported, the crane can tip over, causing the boom and load to fall. Soft soil, loose gravel, or an improper setup with outriggers can all lead to a catastrophic failure.

• Safety Rule: Always use crane pads or cribbing to distribute the crane’s weight, and ensure the ground is solid and stable before any lift begins.

Awareness of these deadly hazards is what separates a safe lift from a catastrophic failure. Be vigilant and never take chances.

Tomorrow, on Struck-By Friday, we'll link these hazards to our theme of being struck by a falling object or swinging load.
