BRIEF DESCRIPTION OF ACCIDENT
A carpenter apprentice was killed when he was struck in the head by a nail that was fired from a powder
actuated tool. The tool operator, while attempting to anchor a plywood form in preparation for pouring a
concrete wall, fired the gun causing the nail to pass through the hollow wall. The nail travelled some twenty-
seven feet before striking the victim. The tool operator had never received training in the proper use of the tool,
and none of the employees in the area were wearing personal protective equipment.

BRIEF DESCRIPTION OF ACCIDENT
A crew of ironworkers and a crane operator were unloading a 20-ton steel slab from a low-boy trailer using a
50-ton crawler crane with 90-foot lattice boom. The operator was inexperienced on this crane and did not know
the length of the boom. Further, no one had determined the load radius. During lifting, the load moved forward
and to the right, placing a twisting force on the boom. The boom twisted under the load, swinging down, under
and to the right. Two employees standing 30 feet away apparently saw the boom begin to swing and ran. The
boom struck one of the employees – an ironworker – on the head, causing instant death. Wire rope struck the
other — a management trainee — causing internal injuries. He died two hours later at a local hospital.

BRIEF DESCRIPTION OF ACCIDENT
Ball and socket connectors are used to attach conductor stringing blocks to insulators on the arms of 90 foot
metal towers of electrical transmission lines. Normally stainless steel cotter keys secure the ball and socket
connector in place. In this case, however, black electrical tape was wrapped around the socket to keep the ball
in place rather than a cotter key. The tape apparently stretched and the ball came loose, dropping the stringing
block approximately 90 feet onto the head of an employee below, one of a four-man erection crew.

INSPECTION RESULTS
As result of the its investigation, OSHA issued citations alleging three serious and two other-than-serious
violations.

OSHA’s construction safety standards include several requirements which, if they had been followed here, might
have prevented this fatality.

BRIEF DESCRIPTION OF ACCIDENT
Employees were dismantling grain spouts at a grain elevator. Sections of the spout were connected by collars. A
ten foot section of a spout weighing 600 pounds was being pulled through a vent hole by a 5-ton winch. As the
spout was being pulled through the opening to the outside, the spout became wedged at the point where the
collar was to pass through. Several employees used pry bars to free the collar which was under tension. The
spout popped out of the vent striking and killing an employee who was standing beside the spout. * Employer
provided but did not require use of hard hats.

INSPECTION RESULTS
As a result of its investigation, OSHA issued two citations alleging serious violations. The employee should have
been able to recognize that this situation was hazardous. Additionally, the investigation revealed that this
employee was not wearing personal protective equipment in this hazardous situation. Had he been wearing a
hard hat this death might have been prevented.
