When portable ladders are used for access to an upper landing
surface, the ladder side rails shall - ANSWER -Extend at least 3
feet above the upper landing surface to which the ladder is
used to gain access; or, when such an extension is not
possible because of the ladder's length, then the ladder stall be
secured at its top to a rigid support that will not deflect, and a
grasping device, such as a grabrail, shall be provided to assist
employees in mounting and dismounting the ladder. In no case
shall the the extension be such that the ladder deflection under
a load would, by itself, cause the ladder to slip off its support.
Non-self-supporting ladders - ANSWER -Shall be used at an
angle such that the horizontal distance from the top support to
the foot of the ladder is approximately one-quarter of the
working length of the ladder (distance along the ladder between
the foot and the top support)
The top or top step of a stepladder shall - ANSWER -NOT be
used as a step
,All masonry walls over 8 feet in height shall - ANSWER -Be
adequately braced to prevent overturning and to prevent
collapse unless the wall is adequately supported so that it will
not overturn or collapse. The bracing shall remain in place until
permanent supporting elements of the structure are in place.
Working under loads. Routes for suspended loads shall be pre-
planned to ensure that no employee is required to work directly
below a suspended load except for: - ANSWER -1. Employees
engaged in the initial connection of the steel, or
2. EMPLOYEES necessary for the hooking or unhooking of the
load
The following additional requirements shall apply for multiple
story structures - ANSWER -1. THE permanent floors shall be
installed as the erection of structural members progresses, and
there shall be not more than eight stores between the erection
floor and the upper-most permanent floor, except where the
structural integrity is maintained as a result of the design
2. AT NO time shall there be more than four floors or 48 feet,
whichever is less, of unfinished bolting or welding above the
foundation or uppermost permanently secured floor, except
where the structural integrity is maintained as a result of the
design.
,3. A FULLY planked or decked floor or nets shall be
maintained within two stories or 30 feet whichever is less,
directly under any erection work being performed.
Landing and placing loads - ANSWER -The weight of a bundle
of joist bridging shall not exceed a total of 1,000 pounds. A
bundle of joist bridging shall be placed on a minimum of three
steel joists that are secured at one end. The edge of the
bridging bundle shall be positioned with 1 foot of the secured
end.
Demolition: When debris is dropped through the holes in the
floor without the use of chutes, the area onto which the
material is dropped shall? - ANSWER Be completely enclosed
with barricades not less than 42 inches high and not less than 6
feet back from the projected edge of the opening above. Signs,
warning of the hazard of falling materials, shall be posted at
each level. Removal shall not be permitted in this lower aread
until debris handling ceases above.
Chutes: - ANSWER -No material shall be dropped to any point
lying outside the exterior walls of the structure unless the area
is effectively protected.
, Access and Egress: - ANSWER -1. Employer shall provide and
maintain safe means of access and egress to all work stations
2. Employer shall provide access and egress in such a
manner that employees are protected from being struck by
excavators, haulage machines, trains and other mobile
equipment
3. Employer shall control access to all openings to prevent
unauthorized entry underground. Unused chutes, manways, or
other openings shall be tightly covered, bulkheaded, or fenced
off, and shall be posted with warning signs indicating "Keep
Out" or similar language. Completed or unused sections of the
underground facility shall be barricaded.
Ladders and Job-made ladders - ANSWER -Each portable
ladder that is not self-supporting. At least four times the
maximum intended load, except that each extr-heavy-duty type
1A metal or plastic ladders shall sustain at least 3.3 times the
maximum intended load. The ability of a ladder to sustain the
loads indicated shall be placed at an angle of 75 1/2 degrees
from the horizontal.
Using pusher assistance will increase the loading rate -
ANSWER -Pushers should be powerful and heavy enough to
push the scrapers through the cut ad accelerate, or boost, the
scrapers as they leave the cut
