Section 296-304-06003. Illumination.

(1) All means of access and walkways leading to working areas as well as the working areas themselves shall be adequately illuminated.

(a) For landside areas, the employer shall provide illumination that meets the levels set forth in Table F-2.

Table F-2

Minimum Lighting Intensities in Foot-Candles

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, the employer shall 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) The employer shall ensure that neither matches nor open-flame devices are used for lighting.

(2) Temporary lights shall meet the following requirements:

(a) Temporary lights shall 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 shall be equipped with heavy duty electric cords with connections and insulation maintained in safe condition. Temporary lights shall 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 shall 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 the employer shall 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 shall 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 shall 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 shall 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 shall meet the requirements of WAC 296-304-02005 (2)(i).

(6) Temporary lighting stringers or streamers shall be so arranged as to avoid overloading of branch circuits. Each branch circuit shall be equipped with overcurrent protection of capacity not exceeding the rated current carrying capacity of the cord used.

(7) Explosion-proof, self-contained lights. The employer shall 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).
