In our plant we have approximately 20 forklifts running between the warehouse and the assembly lines. Aside from building columns, we have 10 floor mounted cranes throughout the plant. All too frequently we have incidents in which a forklift strikes either a building column or crane column. We have painted the columns yellow (floor to 6ft) to make them stand out and installed column protectors to reduce any damage. Ideally though, preventing the collisions is my goal. Does anyone have any advice they could share with regards to measures that have been successful in preventing these types of accidents ?

Thank-you
