Abstract: Employee #1 was working with a four-man crew erecting 65 ft high steel electric transmission towers. A framing crew usually put the towers together on the ground with crossarm strings of insulators, and conductor-stringing blocks on the ends of the insulators (bales). There was a ball and socket connector on top of the stringing block and on the bottom of the bales that should have been secured with a stainless steel cotter key. Instead, it was held in place with black electrical tape. While the crew was erecting a tower, a conductor-stringing block fell approximately 65 ft, striking Employee #1 on the head and killing him
