Vice President-Engineering

Dear Mr. Puccinelli:

This is in response to your correspondence of June 3, 1977, regarding wheel locks on a special rolling scaffold to be used to erect large tanks.

The Occupational Safety and Health Administration (OSHA) has reviewed your letter and the accompanied drawing No. E-76025-4.

OSHA does not consider 29 CFR 1926.451(e) Manually Propelled Mobile Scaffolds, applicable to scaffolds, such as yours, that are: 1) limited in movement to only two directions by the use of fixed castors; and, 2) in direct contact with the structure under construction, which also limits the movement of the scaffolds to the same two directions, and 3) movable only with considerable horizontal force.

Where there are no specific scaffold standards on a particular scaffold 29 CFR 1926.451(a) Scaffolding, General Requirements, are to be met. In addition, adequate safeguards should be provided to prevent the accidental displacement of the scaffold.

If I may be of further assistance, please feel free to contact me.

Sincerely,



John K. Barto,
Chief
Division of Occupational Safety Programming
