Dear Mr. Mann:
Thank you for your April 5, 2012 letter to the Occupational Safety and
Health Administration (OSHA). Since it involves construction issues, it
has been forwarded to the Directorate of Construction for response.
You have a specific question regarding access to a semi-trailer used to
store parts on a job site. This letter constitutes OSHA's
interpretation of only the requirements discussed and may not be
applicable to any question not delineated in your original
Question: Is it permissible to use a metal ramp to unload parts from a semi-trailer when needed?
Response: Yes, the OSHA standards do not have specific
requirements for accessing a portable storage trailer on a job site. A
ramp could be a suitable means of access. However, where the height of
the trailer floor exceeds 6 feet, guard rails or other fall protection
will be required.
29 CFR 1926.501(b)(6): requires that "Each employee on ramps, runways,
and other walkways shall be protected from falling 6 feet (1.8m) or more
to the lower level by guardrail systems."
James G. Maddux, Director
Directorate of Construction
