A 45-year-old male Hispanic construction laborer (the victim) died after a retractable leg on a portable silo collapsed, causing the silo to fall over and crush him. The silo contained aggregates to mix stucco, which other crew members were applying to chimneys on the roof of newly constructed condominium units. The victim was operating the silo, dumping the aggregates through the silo's chute into a cement mixer to prepare the stucco that was to be applied. A coworker used a forklift to raise the silo off the victim and other workers pulled the victim clear. The victim had a faint pulse. The emergency medical services responded and transported the victim to the hospital where he was pronounced dead. NIOSH investigators concluded that, to help prevent similar incidents, employers should: 1. ensure that equipment is set up according to manufacturers' recommendations and specifications; 2. inspect equipment on a daily basis before the start of work and immediately repair any damaged components; and, 3. develop, implement, and enforce a comprehensive written safety program for all workers which includes training in the recognition of hazards that might be encountered during the performance of their duties and the avoidance of unsafe conditions.
