(1) All means of
access and walkways leading to working areas as well as the working areas
themselves must be adequately illuminated.
(a) For landside areas, you must provide
illumination that meets the levels set forth in Table F-2.

Note to Table F-2: The required illumination
levels in this table do not apply to emergency or portable
lights.
(b) For vessels and
vessel sections, you must provide illumination that meets the levels set forth
in the table to (a) of this subsection or meet ANSI/IESNA RP-7-01.
(c) When adequate illumination is not
obtainable by permanent lighting sources, temporary lighting may be used as
supplementation.
(d) You must
ensure that neither matches nor open-flame devices are used for lighting.
(2) Temporary lights
must meet the following requirements:
(a)
Temporary lights must be equipped with guards to prevent accidental contact
with the bulb, except that guards are not required when the construction of the
reflector is such that the bulb is deeply recessed;
(b) Temporary lights must be equipped with
heavy duty electric cords with connections and insulation maintained in safe
condition. Temporary lights must not be suspended by their electric cords
unless cords and lights are designed for this means of suspension. Splices must
have insulation with a capacity that exceeds that of the original insulation of
the cord; and
(c) Cords must be
kept clear of working spaces and walkways or other locations in which they are
readily exposed to damage.
(3) Exposed noncurrent-carrying metal parts
of temporary lights furnished by you must be grounded either through a third
wire in the cable containing the circuit conductors or through a separate wire
which is grounded at the source of the current. Grounding must be in accordance
with the requirements of WAC
296-304-08003(2).
(4) Where temporary lighting from sources
outside the vessel is the only means of illumination, portable emergency
lighting equipment must be available to provide illumination for safe movement
of employees. If natural sunlight provides sufficient illumination, portable or
emergency lights are not required.
(5) Employees must not be permitted to enter
dark spaces without a suitable portable light. The use of matches and open
flame lights is prohibited. In nongas free spaces, portable lights must meet
the requirements of WAC
296-304-02005(2)(i).
(6) Temporary lighting stringers or streamers
must be so arranged as to avoid overloading of branch circuits. Each branch
circuit must be equipped with overcurrent protection of capacity not exceeding
the rated current carrying capacity of the cord used.
(7) Explosion-proof, self-contained lights.
You must provide and ensure that each employee uses only explosion-proof,
self-contained temporary and portable lights, approved for hazardous conditions
by a nationally recognized testing laboratory (NRTL), in any area that the
atmosphere is determined to contain a concentration of flammable vapors that
are at or above ten percent of the lower explosive limit
(LEL).
