OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at

Mr. Bradley D. Closson
Vice President
North American Crane Bureau, Inc.
610 Gateway Center Drive, Suite G
San Diego, CA 92102

Dear Mr. Closson:

The purpose of this letter is to respond to your correspondence of August 28, 1997 regarding certification requirements under the new Longshoring Regulations. You are correct that testing under ILO 152 is required after July 16, 2001 and that proof load testing must be performed at least every five years. This change in the testing cycle should not affect North American Crane Bureau, Inc. as the change only applies to the gear on ocean going cargo vessels which is normally inspected and tested by the major classification societies. These requirements will not apply to the Shore-based Material Handling Devices or Floating Cranes and Derricks that your corporation has been accredited to certify. The four year requirement for proof load testing Shore-based Material Handling Devices and Floating Cranes and Derricks will remain unchanged.

We hope this information helps to clarify the matter. We have enclosed a copy of the new regulations for your reference and use. Your interest in occupational safety and health matters is greatly appreciated.


Joe Nolan, Chief
[Office of Maritime Enforcement]
