Guardrails beside pickling and galvanizing tanks

Summary A galvanizing company requested a variance from open-sided platform guardrail rules. OSHA said the pickling tank sides met the height requirement and the galvanizing tank's ledge and wall gave effective protection despite a lower height, so it would treat that condition as de minimis and require no variance. OSHA archives the letter.

Mr. Ernest Demetriades
Vice President
Oaks Corners Galvanizing
Division of Elderlee, Inc.
[Recipient address omitted]
Dear Mr. Demetriades:

Assistant Secretary Eula Bingham has asked me to respond to your letter dated November 3, 1978, requesting a variance from Section 1910.23(c)(3) Protection of Open-Sided Floors, Platforms and Runways, of the Occupational Safety and Health Standards.

Your application for variance has been reviewed and discussed with our appropriate technical staffs. The 50" sides on the pickling tank exceed the height requirement for a standard guardrail, and, therefore, are in compliance with the standard. The 31" height from the working platform to the top of the galvanizing tank is less than that required for a standard guardrail. However, the 30" ledge width combined with the 31" height creates a situation where employees are effectively protected from the hazard covered by the standard. Therefore, this situation would be considered de minimis and no abatement would be required.

For these reasons, no variance from Section 1910.23(c)(3) is necessary for either your pickling tanks or your galvanizing kettle, and no further action will be taken on your variance application.

Any further questions on this should be directed to the Rochester Area Office, Joseph Rufolo, Area Director, U.S. Department of Labor - OSHA, Federal Office Building, Room 600, 100 State Street, Rochester, New York 14614, telephone: (716) 263-6755.

Sincerely,

James J. Concannon
Director
Office of Variance Determination
