Dear Mr. Thompson:

This is in response to your July 2 letter requesting a compliance determination from the Occupational Safety and Health Administration (OSHA) regarding your "Girder Lock Overhang Form System." I apologize for the delay in responding to your inquiry.

We have reviewed the product information that you provided and have determined that if the C-Caddy is used as described in your letter, OSHA would consider it a suspended scaffold and the requirements in 1926 Subpart L (1926.451) would apply. This determination is contingent upon the crane hoist drum being dogged off and the C-Caddy being stationary at all times while employees are on the platform. A safe means of access and egress is required to and from the C-Caddy and as stated in your letter, all persons must be tied-off while on the platform.

Please note that if the C-Caddy is moved while employees are on it, OSHA would consider it a crane suspended personnel platform and the requirements contained in 1926.550(g) would apply.

If you wish to apply for a formal variance from one or more of these standards, please refer to 29 CFR 1905 and contact OSHA's Office of Variance Determination in the Directorate of Technical Support at (202) 219-7193.

If we can be of any further assistance, please contact me or Mr. Dale Cavanaugh of my staff at (202) 219-8136.

Sincerely,

Roy F. Gurnham, P.E., J.D.

Dear Mr. Roy Gurnham;

Enclosed are Erection Drawings, Packing Lists, Erection Manual and Technical Data Sheet for our "Girder Lock Overhang Form System".

Please review this System in general and specifically the access platform attached to the lower portion of the C-Caddy shown on drawing E-3 for compliance with OSHA requirements. In addition to the safety notes shown, we have also required that the crane line be dogged off before personnel are allowed on the platform and that a trial lift be performed each time the crane is set up in a new location. This platform was designed following OSHA guidelines 1926.451 since it is attached to the gang forms and is never manned when in motion. An OSHA audit specialist has contended that 1926.550(g) applies.

I look forward to your response concerning this system. If you have any questions please call me.

Sincerely,

Clark W. Thompson, P.E.
Vice President
