How should hot work be managed when a crane is in use nearby?

• A. Ensure no ignition sources near the crane, isolate electrical equipment, assign a fire watch, and maintain safe clear zones.
• B. Burns are acceptable if necessary.
• C. Open flames near crane with supervisors present.
• D. Hot work can proceed without additional precautions.

Answer: (A)

Hot work near a crane must minimize ignition risk and protect people and the crane path. Sparks, heat, and molten metal from welding, cutting, or grinding can ignite flammable materials, and a crane’s overhead movement can spread fire or strike workers if precautions aren’t in place. The safest approach is to remove ignition sources in the area around the crane, isolate electrical equipment to prevent sparks or arcing, assign a trained fire watch who can quickly detect and respond to any fire, and maintain clear zones where hot work is prohibited and the crane operates. This combination directly prevents ignition, ensures rapid response if a fire starts, and keeps the work area and equipment safe.

Other options rely on supervision or partial precautions, which do not adequately address the real ignition and interaction hazards present when hot work is conducted near moving crane components.
