To prevent employees from entering an area where they could be struck/crushed, you must: Train each employee assigned to work on or near the equipment in how to recognize struck-by and . Employers must provide a training program that teaches employees who might be exposed to fall hazards: How to recognize such hazards and how to minimize them. Exception: When the employer can demonstrate that it is neither feasible to erect such barriers on the ground nor on the equipment, the hazard areas must be clearly marked by a combination of warning signs (such as "Danger--Swing/Crush Zone") and high visibility markings on the equipment that identify the hazard areas. Monitor the cranes operations and provide guidance as needed. Prior to starting all demolition operations, OSHA 1926.850 (a) requires that an engineering survey of the structure be conducted by a competent person.

Everyone associated with a crane needs to stay alert and focused on the job at hand - especially on critical or difficult lifts. Electricity travels in closed circuits, and its normal route is through a conductor. Nearly 80 percent of these upsets can be attributed to predictable human error when the operator inadvertently exceeds the cranes lifting capacity. If the use of a power tool can result in flying sparks, metal shavings, wood chips, splashes, or other debris, workers should: Protect themselves by wearing the proper PPE (Your Answer).

If you feel that an OSHA inspection is needed to get hazards corrected at your workplace, which is your best option? -- The current's path. Secure loads to prevent shifting or slipping during lifts. 10. Move the personnel platform slowly and cautiously and have rotation-resistant rope with a safety factor of 10 Have all brakes and locking devices set when the occupied personnel platform is in stationary position The three main scaffold types are aerial lifts, supported scaffolds and Suspended scaffolds This person watches for interference while the operator overhead focuses on the task at hand. The OSHA standard mandates that any time a worker is at a height of six feet or more, the worker is at risk and needs to be protected. One way to reduce the risk of falling materials is to perform regular maintenance of hoists. Occupational Safety & Health Administration. Between 1989 and 2009, there were 86 identified incidents involving the collapse or major structural failure of a tower crane. 8. Ensure that all personnel involved in the operation understand and follow safety protocols. 4. Improper grounding of circuitry and equipment. OSHA 1926.1424 is designed to protect employees who work near a crane from being struck or crushed by the crane's rotating superstructure.

Federal Aviation Administration - A Notice of Proposed Construction or Alteration may be required for mobile cranes located in the vicinity of the Virginia Tech Airport, or where the type of structure exceeds a certain height. If the boom contacts a power line, the operator holding the control box is usually electrocuted instantly. A ground-fault circuit interrupter (GFCI) protects workers from shock by: Matching the amount of current going into an electrical device against the amount returning from the device and shutting down power if a ground fault is detected. Where the operator knows that an employee went to a location covered by paragraph (a)(1) of this section, the operator must not rotate the superstructure until the operator is informed in accordance with a pre-arranged system of communication that the employee is in a safe position. This scaffold is simply a rope attached to a harness with an assembly like a boatswain's chair for the worker to sit in. Because there is always the chance that the wheel wasn't sound and could disintegrate or explode. -- Engineering and Administrative Controls espaol | Architects & Engineers portal | Lift-Lab, Home Overhead Crane SafetyThree Major Hazards and Preventative Measures.
