Section 5(a)(1) of the Occupational Safety and Health Act of 1970: The employer did not furnish employment and a place of employment which were free from recognized hazards that were causing or likely to cause death or serious physical harm to employees in that employees were exposed to a hammerhead tower crane that was not provided with a braking means with holding power in both directions to prevent movement of the rotating upper structure during operation, and not capable of being set in the holding position and remaining so without further action on the part of the operator: a)Bungy Jump Site - A braking means with holding power in both directions to prevent movement of the rotating upper structure during operation, and capable of being set in the holding position and remaining so without further action on the part of the operator was not provided to prevent movement of rotating upper structure (Jib) of the Raimondi hammerhead tower crane, model number ER 135, serial number TK 5515-8, exposing employees, working next to the personnel platform being moved and lifted by the crane, to the hazard of being struck by the platform. Among other methods, one feasible and acceptable abatement method to correct this hazard is to provide a braking means with holding power in both directions to prevent movement of the rotating upper structure during operation, and capable of being set in the holding position and remaining so without further action on the part of the operator as delineated in the American National Standards Institute/American Society of Mechanical Engineers standard for Hammerhead Tower Cranes B 30.3, Section 3-1.6.2 Slewing Brakes.
