29 CFR 1926.500(b)(8)

April 14, 1978

Mr. John N. Roche
Product Engineer
R. D. Werner Company, Inc.
Post Office Box 580
Greenville, Pennsylvania 16125

Dear Mr. Roche:

This is in response to your letter dated March 22, 1978, concerning the use of plywood decked Aluma-Planks.

The 2-3/4" x 2-3/4" notch cut into the plywood at each end of the aluma-plank would be a floor hole as defined by 29 CFR 1926.502(a). Floor holes, into which persons can accidentally walk, need to be guarded by either a standard railing with standard toeboard on all exposed sides, or a floor hole cover of standard strength and construction that is secured against accidental displacement as required by 29 CFR 1926.500(b)(8).

The above mentioned occupational safety and health standards and the interpretation of the codes mentioned in your letter confirm the need for a cover or equivalent protection to close the center notches at each end of the plank, when they are open.

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


Janet H. Sprickman,
Acting Chief
Division of Occupational
