|MEMORANDUM FOR:||GILBERT J. SAULTER
|FROM:||GROVER C. WRENN
Director Federal Compliance and State Programs
|SUBJECT:||Kelly Bushings on Oil Well Drilling Rigs
|REF:||Kelly Bushings on Oil Well Drilling Rigs
November 26, 1979
As stated in my memorandum dated June 19, 1979 (copy attached), Kelly Bushings on oil drilling rigs that are smooth and do not present a potential hazard to employees that might come in contact with the bushings or be pulled into the bushing do not require guarding. However, Kelly Bushings with projections or indentations can present a potential hazard to employees who could come in contact with the bushing or could be pulled into the bushing by a chain, wire, hose, etc., which may become entangled with the bushing. Under such circumstances, the bushing shall be guarded or employers shall be appropriately cited.
The enclosed photographs of Kelly Bushings cannot be properly evaluated for potential hazards. Compliance officers must determine whether Kelly Bushings present a potential hazard on a case by case basis as observed during inspections at the job sites.
