Dear Mr. May:

This is in response to your letter dated August 4, 1976, addressed to Donald A. Shay, regarding metal manhole ladder standards in 29 CFR 1910.268(h)(8) and confirms a telephone conversation with a member of my staff. You state that the Occupational Safety and Health Administration (OSHA) agreed in previous meetings and correspondence that the metal ladders you use and leave in the manhole are not portable and ask that we clarify OSHA Program Directive #100-46 so that metal manhole ladders of the type you describe are excluded from the requirements of 29 CFR 1910.268(h)(8).

As you know, the Program Directive states that 29 CFR 1910.268(h)(8)(i) through (vi) applies to "portable" metal manhole ladders used in the telecommunication industry. Therefore, if your ladders are "portable" they must comply with that standard's requirements.

Based on your discussions with a member of my staff, and further review, we have concluded that some of the ladders described in your letter are portable metal ladders. As such, standards 29 CFR 1910.268(h)(8)(i) through (vi) are applicable.

Although the phrase "portable ladder" is not defined in the OSHA standards, it is clear that in promulgating OSHA standards the Secretary distinguished between portable and fixed ladders, see 29 CFR 1910.26 and 1910.27. 29 CFR 1910.21(e)(2) defines a fixed ladder as a ladder permanently attached to a structure, building, or equipment. It follows therefore that a portable ladder is one that is not fixed, i.e., one that is not permanently attached.

The information you furnished indicates some of your metal manhole single ladders are not permanently attached to anything, are moved around in the manhole, and are kept in the manhole. OSHA's position is that under these conditions the ladders would be portable metal ladders.
