Video made by J.L. Davidson Co. Inc.
Showing the effects of dropping a 200 lbs (approx 90 kg) sandbag on rebar and other protruding objects. California law requires 250lbs!
Also 90 and 180 degree bends prove to be ineffective in protecting against impalement.
This video was instrumental in banning bent rebar as a means of preventing impalement injuries in California.
This section of video is a test, dropping 200 lbs from 10 feet (~3.05 meter) onto anchor bolts (11″ protrusion). See full video for the complete 20 minutes.
