UNION ELECTRIC CO.
Grant of Variance
I. Background. Union Electric Company, No. 1 South Memorial Drive, St. Louis, Missouri 63102
made application pursuant to section 6(d) of the Williams-Steiger Occupational Safety and
Health Act of 1970 (84 Stat. 1596; 29 U.S.C. 655) and 29 CFR 1905.11 for a permanent variance,
and for an interim order pending a decision on the application for a variance, from the safety
standards prescribed in 29 CFR 1910.28 (g) (1). The standard requires that two-point suspension
scaffolds be a minimum of 20 inches in width. The facility affected by this application is Union
Electric Company, Labadie Plant, Labadie, Missouri 63055. Notice of the application, and of the
granting of an interim order, was published in the FEDERAL REGISTER on January 16, 1974 (39
FR 2052). The notice invited interested persons, including affected employers and employees, to
submit written data, views, and arguments regarding the grant or denial of the variance requested.
In addition, affected employers and employees were notified of their right to request a hearing
on the application for a variance. No written comments or requests for a hearing have been received.
II. Facts. In the inspection and maintenance of the applicant's controlled circulation steam
generators it is necessary to raise a two-point suspension scaffold into areas having nominal
clearances of 21.45" and 22.44" or less. Certain other equipment has similar close clearance areas
requiring the use of the two-point suspension scaffold.
It has been found to be virtually impossible to hoist a 20" wide scaffold into these areas because
of the potential hazard of the scaffold becoming wedged. Therefore, the applicant has built a
scaffold with a 17 1/2" width which conforms in all other respects to the requirements of 1910.28(g).
This scaffold is used only' in the close clearance areas where the 20" width would present a hazard.
III. Decision, Section 1910.28(g) (1) requires that a two-point suspension platform be a minimum of
20" in width. This is intended to provide sufficient space so that employees working on the scaffold
will have room to maneuver as required during the performance of their duties.
In the applicant's close clearance areas, such as the controlled circulation steam generators and
other similar equipment, there is insufficient clearance to maneuver a 20" wide scaffold with out
the risk of it becoming wedged. Instead, the applicant is providing a 17 1/2" scaffold for use in
the close clearance areas. The inside walls of the equipment provide protection to the employees
while performing their work. Therefore, the use of the 17 1/2" scaffold in these areas will provide
a place of employment as safe as would be obtained by complying with standard.
IV. Order. Pursuant to authority in section 6(d) of the Williams-Steiger Occupational Safety and
Health Act of 1970, and in Secretary of Labor's Order No. 12-71 (36 FR 8754), it is ordered that
Union Electric Company be, and it is hereby, authorized to use two-point suspension scaffolds
17 1/2" in width while performing maintenance and inspection operations in the close clearance areas
of the steam generators and other equipment, provided that this special scaffold is used only in areas
where the clearance does not permit the use of 20" scaffolds. As soon as possible Union Electric
Company shall give notice to affected employees of the terms of this order by the same means required
to be used to inform them of the application for variance.
Effective date. This order shall become effective on October 18, 1974, and shall remain in effect
until modified or revoked in accordance with section 6(d) of the Williams-Steiger Occupational Safety
and Health Act of 1970.
Signed at Washington, D.C. this 9th day of October 1974.
JOHN H. STENDER,
Assistant Secretary of Labor.
