The items you mentioned—cranes, ladders, scaffolds, backhoes, and paint rollers—each pose different types of hazards at a worksite.
Falling Objects: Cranes are often used to lift and move heavy loads. If not properly secured, these loads can fall, posing a significant hazard to workers below.
Collapse: Improper assembly, operation, or maintenance of cranes can lead to collapse, endangering both workers and the structure.
Falls: Ladder-related falls are a common hazard. This can occur if a ladder is not set up on a stable surface, is not the correct height, or if a worker overreaches.
Incorrect Use: Workers might use ladders for purposes other than what they are designed for, leading to accidents.
