Table 3-2. Altitude Correction Factors
Work Location. The location of the work will determine whether climbing or
confined space training along with fall and/or respiratory protection are mandatory (refer
to Chapter 4). Safety standards require protection from excessive noise and provision of
minimum illumination at any applicable work site.
3-1.2.1 Noise. Follow local procedures regarding hearing protection. Wherever
hazardous noise area signs are posted, hearing protection must be used as prescribed.
3-1.2.2 Minimum Illumination. Ensure the working area has adequate illumination.
Provide temporary lighting where natural or installed artificial illumination is not
sufficient. Survey facility electrical equipment rooms to determine if lighting has been
connected to a timer/motion control device. Ensure timers/motion control devices are
disengaged prior to beginning any electrical work operations.
PUBLIC SAFETY. Protect the public around the work area by safely guiding
unqualified personnel and traffic away from workers, equipment, and excavations.
Warning Devices. Locate appropriate barriers, warning signs, traffic cones,
and lights at approaches to and at work areas, excavations, open manholes, parked
equipment, and other hazards. Take special precautions for any areas where reduced
visibility occurs, such as night operations or in fog. Immediately remove warning
devices after removal of hazards and equipment. Provide flagmen if there is any doubt
as to whether the warning devices will be adequate as controls, such as in areas with
obstructed vehicular traffic.
Flagmen. Flagmen must be used whenever there is any doubt of the
effectiveness of warning devices. This often occurs on busy roadways or during
commuting hours on less traveled streets. Flagmen must wear brightly colored and
highly reflective warning vests.
