A 24-year-old male construction worker died after steel beams fell on him when the nylon slings that were carrying them failed. The decedent and a co-worker were unloading a delivery truck that contained approximately 42,000 pounds of structural steel. A 450-ton crane on site was assisting with the unloading process. The lifting procedure was discussed with the decedent and co-worker's senior supervisor on-site. The first and second lifts were done without incident. The senior supervisor then left the job site to perform other responsibilities. The construction workers rigged the rest of the steel and picked it up as one load, instead of the three separate loads as planned. No consideration was given to the rated capacity of the slings, devices to protect the nylon slings from the sharp edges of the steel, or a tag line to guide the steel being lifted. The first and second loads weighed approximately 8,700 pounds apiece. The third load was approximately 24,000 pounds. The lift was near its maximum radius when the nylon slings failed, dropping its load on top of the decedent. The CA/FACE investigator determined that, in order to prevent future occurrences, employers, as part of their Injury and Illness Prevention Program, should: 1. Ensure that nylon slings are not overloaded. 2. Ensure chafing material is used to protect nylon slings from sharp edges. 3. Ensure that all elevated loads are controlled with tag lines. 4. Ensure crane operators making lifts are aware of the rating capacity of the rigging devices used to lift the load.
