Effective Date of Rule: December 1, 2007.

     Purpose: The Occupational Safety and Health Administration (OSHA) promulgated a new fire protection rule for shipyard employment that incorporated by reference, National Fire Protection Association (NFPA) standards. In this adoption, we replaced the references to those NFPA standards by adding the most recent versions. These amendments will enhance DOSH's fire protection in our shipyard standard by adding the most current NFPA consensus standards to our chapter. These changes will benefit the safety of employees by requiring employers to comply with the newer standards, which may be even more protective than the older standards.

     These changes will not result in additional compliance costs.

     (2) Requirements for performing cleaning or cold work.

     (a) Liquid residues of hazardous materials shall be removed from work spaces as thoroughly as practicable before employees start cleaning operations or cold work in a space. Special care shall be taken to prevent the spilling or the draining of these materials into the water surrounding the vessel, or for shore-side operations, onto the surrounding work area.

     (b) Testing shall be conducted by a competent person to determine the concentration of flammable, combustible, toxic, corrosive, or irritant vapors within the space prior to the beginning of cleaning or cold work.

     (c) Continuous ventilation shall be provided at volumes and flow rates sufficient to ensure that the concentration(s) of:

     (i) Flammable vapor is maintained below 10 percent of the lower explosive limit; and

Note to (2)(c)(i):

Spaces containing highly volatile residues may require additional ventilation to keep the concentration of flammable vapors below 10 percent of the lower explosive limit and within the permissible exposure limit.

     (ii) Toxic, corrosive, or irritant vapors are maintained within the permissible exposure limits and below IDLH levels.

     (d) Testing shall be conducted by the competent person as often as necessary during cleaning or cold work to assure that air concentrations are below 10 percent of the lower explosive limit and within the PELs and below IDLH levels. Factors such as, but not limited to, temperature, volatility of the residues and other existing conditions in and about the spaces are to be considered in determining the frequency of testing necessary to assure a safe atmosphere.

Note to (2)(d):

See WAC 296-304-02013--Appendix ((A)) B, for additional information on frequency of testing.

     (e) Spills or other releases of flammable, combustible, toxic, corrosive, and irritant materials shall be cleaned up as work progresses.

     (f) An employee may not enter a confined or enclosed space or other dangerous atmosphere if the concentration of flammable or combustible vapors in work spaces exceeds 10 percent of the lower explosive limit.

     Exception: An employee may enter for emergency rescue or for a short duration for installation of ventilation equipment provided:

     (i) No ignition sources are present;

     (ii) The atmosphere in the space is monitored continuously;

     (iii) The atmosphere in the space is maintained above the upper explosive limit; and

     (iv) Respiratory protection, personal protective equipment, and clothing are provided in accordance with WAC 206-304-090 through 296-304-09007.

Note to (2)(f):

Other provisions for work in IDLH and other dangerous atmospheres are located in WAC 296-304-090 through 296-304-09007.

     (g) A competent person shall test ventilation discharge areas and other areas where discharged vapors may collect to determine if vapors discharged from the spaces being ventilated are accumulating in concentrations hazardous to employees.

     (h) If the tests required in (g) of this subsection indicate that concentrations of exhaust vapors that are hazardous to employees are accumulating, all work in the contaminated area shall be stopped until the vapors have dissipated or been removed.

     (i) Only explosion-proof, self-contained portable lamps, or other electric equipment approved by a National Recognized Testing Laboratory (NRTL) for the hazardous location shall be used in spaces described in subsection (1) of this section, until such spaces have been certified as "safe for workers."

Note to (2)(i):

Battery-fed, portable lamps or other electric equipment bearing the approval of a NRTL for the class, and division of the location in which they are used are deemed to meet the requirements of (i) of this subsection.

     (j) The employer shall prominently post signs that prohibit sources of ignition within or near a space that has contained flammable or combustible liquids or gases in bulk quantities:

     (i) At the entrance to those spaces;

     (ii) In adjacent spaces; and

     (iii) In the open area adjacent to those spaces.

     (k) All air moving equipment and its component parts, including duct work, capable of generating a static electric discharge of sufficient energy to create a source of ignition, shall be bonded electrically to the structure of a vessel or vessel section or, in the case of land-side spaces, grounded to prevent an electric discharge in the space.

     (l) Fans shall have nonsparking blades, and portable air ducts shall be of nonsparking materials.
