34 Pa. Code § 6.30 - Ladders
(a)
Where
required. When a runway, stairway or safe inside means of access to a
scaffold is not provided, a ladder shall be provided for all such scaffold
platforms more than 45 inches above the ground or floor.
(b)
Construction. Ladders
for scaffolds shall be built according to Chapter 21 (relating to ladders),
except where such construction is conclusively provided impracticable by reason
of unusual working conditions. Particular care shall be taken regarding the
quality of wood used in the construction of all ladders.
(c)
Location and guardrails.
When practicable all ladders shall be placed on the outside of a scaffold. If
the landing is on a platform extending from the scaffold platform or building,
such landing shall be provided with guardrails. If the ladder is built inside
of a scaffold the opening in the flooring through which it comes shall be
protected by guardrails.
(d)
Single pole ladders. The use of single pole ladders is
prohibited.
(e)
Fastenings
and placement. Ladders shall be securely fastened at the top and
bottom. The top shall extend not less than 36 inches above the platform or
floor served and the landing rung shall be as close to the level of the floor
or platform as possible. Ladders shall not be placed on boxes or other insecure
footings to bring them up to a desired height.
(f)
Length. The ladder shall
not exceed 30 feet in length except when it is absolutely necessary.
(g)
Extended ladders. The
extended ladder shall be securely fastened to the lower ladder by means of two
iron rungs, threaded at both ends, placed firmly in the slots provided for such
purpose and held in place by tight-fitting nuts and washers. The side bars at
the base of the slots shall be additionally strengthened to prevent splitting
of the wood.
(h)
Number of
persons on ladder. When workmen carry material up or down a ladder
not more than one workman shall be permitted on a single ladder at one time.
Where work being done necessitates frequent use of a ladder for this purpose,
the remaining alternative is to build two ladders, one for up travel and one
for down travel.
(i)
Bracing. When ladders are of a length sufficient to possess a
tendency toward springiness when sustaining weight, bracing shall be provided
to overcome such springiness. This particularly applies to extended
ladders.
(j)
Trestle
ladders. Where "A" or trestle ladders are used to support planking,
they shall be constructed according to Chapter 21.
