When is the appropriate time for the fork lift operator to sound the horn?

A forklift operator should sound the horn when approaching intersections, blind spots, or areas where visibility is limited to alert pedestrians and other operators of their presence. The horn should also be used when backing up or maneuvering in tight spaces to ensure safety. Additionally, it's important to signal when entering or exiting a building or other confined areas. Regular communication through horn usage helps prevent accidents and enhances overall workplace safety.
