Stationary Tramways and Trestles
|
|
Without adequate clearance or signs that warn of
possible hazards, workers may be injured when working on or near
tramways and trestles. OSHA requires that these hazards be
adequately marked and that tramways and trestles be kept in good
repair. Appropriate safety devices also must be in place.

Hazards/Solutions:
Workers may be injured to due unsafe foundations or walkways.
Workers may also be injured if tramways and trestles do not have
adequate clearance, or if signs and signals are not installed.
- Tramways and trestles must have
substantial mud sills or foundations that are frequently inspected
and kept in repair. Control foot traffic when sharing the tramways and trestles
with vehicles. Provide a walkway with standard handrails at the outer edge and shear timber on
the inner edge. This walkway must allow adequate clearance to vehicles. When walkways cross over other
thoroughfares, they must be solidly fenced at the outer edge to a
height of 42 inches.
1910.265(c)(19)(i)
- Stationary tramways and trestles must have a vertical
clearance of 22 feet over railroad rails. When constructed over carrier
docks or roads, they must have a clearance of 6 feet above the driver's
foot rest on the carrier, and no less
than 12 feet from the roadway. In existing operations where it is
impractical to obtain such clearance, telltales, electric signals, signs
or other precautionary measures need to be installed. 1910.265(c)(19)(ii)
