Osha STRUCK-BY HAZARDS
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. What should be recommended to prevent this accident from happening again?
-Rigging and equipment must be inspected regularly and maintained in safe operating condition as required by general provisions of OSHA's construction. -Employees must be instructed to recognize and avoid unsafe conditions and be made aware of regulations which apply to the work and the work area to eliminate safety and health hazards as required in the safety
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 traveled 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. What should be recommended to prevent this accident from happening again?
-Train employees using powder-actuated tools in safe operation of the particular tool. -Train employees on operating powder actuated tools to avoid firing into easily penetrated materials. -Institute a program for frequent and regular inspections of job site, materials, and equipment by a competent person(s). -Require employees exposed to the potential hazards associated with flying nails to use appropriate personal protective equipment.
