The Contractor is responsible for accomplishing all the work described herein. The Contractor shall perform all removals, relocations, alterations, and installations, provide all staging, cranes, gas freeing, transportation, etc., necessary to accomplish the intent of this specification. The work shall be performed to the satisfaction of the regulatory bodies indicated and the MSC representative. The cost of this system is for the Contractor’s account and not reimbursable.

I-2 Location:

The decontamination station shall be constructed in or near an existing passageway as close to the main deck level as the Vessel's arrangement allows.

I-3 Electrical Modifications:

I-4 Incandescent Fixtures:

Incandescent watertight fixtures will be installed in the decontamination station. The fixtures are to provide an illumination level of 10-foot candles in both the shower and the outer garment removal space. The incandescent watertight fixtures are to be controlled by two, 3-way switches. One of these switches will be mounted in the existing passageway next to the new door to the decontamination station as depicted in MSC Plan No. STD-802-4844759.

I-5 Nameplates:

Phenolic nameplates with black lettering will be mounted adjacent to the appropriate devices for identification.

I-6 Painting General:

The entire exposed surface of all new, modified and disturbed spaces, including all overheads, decks, bulkheads, fixtures, stanchions, railings, piping, ducts, etc., will be painted. New steel bulkheads, deck, etc., will be painted in accordance with COMSCINST 4750.2 Series, and MSC Plan No. STD-802-4844759 for the decontamination station. All new steel will be suitably blasted and primed with an inorganic zinc primer, and top-coated with a compatible finish coat. Paint type and color schemes will be in accordance with COMSCINST 4750.2 Series for shower space, passageway and exterior deckhouse, as appropriate, and MSC Plan No. STD-802-4844759 for the decontamination station. All existing steel modified or disturbed by this work will be properly cleaned, primed, touched-up and restored to original condition.

I-7 Restoration to Original Condition:

All areas, such as stairwells, passageways, and spaces disturbed by the Contractor in the performance of this specification, will also be painted to restore to original color and condition.

I-8 Preparation of Surfaces:

Prior to painting, all surfaces will be thoroughly cleaned and all rust, preservative, grease, oil, and other foreign matter will be completely removed. All loose and blistered paint and rusted areas will be thoroughly scraped and power wire brushed to a clean and smooth surface, free of rust, scale and foreign matter. All rough and jagged edges will be power wire brushed and sanded to a smooth and tapered finish.

I-9 Application:

Paint will be applied with care and necessary steps will be taken to prevent paint from coming in contact with nameplates, grease fittings, tile, doors and trim, valve stems, machine threads, brass, chromium, aluminum and other bright metal surfaces, rubber gaskets, knife edges on door frames and hatches, and unpainted parts and fittings. All paints will be applied in accordance with manufacturer's recommendation.

I-10 Condition:

All paints supplied for this work will be delivered to the job in sealed containers, plainly marked by the manufacturer, identifying type and grade of paint. The U.S. Government reserves the right to request evidence that paints were manufactured in accordance with formulas specified.

I-11 Stenciling and Lettering:

Required stenciling, marking and/or lettering that has been overpainted will be redone to conform with USCG regulations, MSC requirements, and paragraph (iv) below.

I-12 Spray Painting:

Spraying of paint is acceptable provided that masking procedures are properly performed and approved by an MSC representative prior to applying any paint. Excessive use of thinner will not be permitted.

I-13 Identification Plates/Markings:

Plates and markings for all new and/or altered spaces, piping, valves, controls, will be installed in accordance with MSC Plan No. STD-802-4844759, COMSCINST 4750.2 Series and COMSCINST 9280.3 Series, and as specified herein.

I-14 Stenciling of Piping:

New or modified piping, 1 1/2 IPS or larger will be labeled at their terminus on the weather deck. Identification will be by stenciling, in contrasting color, 1 inch high lettering, on an adjacent bulkhead or by attaching a brass or plastic label engraved with 1.4-inch lettering.

I-15 Removal of Obsolete Plates and Markings:

Existing nameplates and markings made obsolete shall be removed.

I-16 Contaminated Clothing Disposal Locker Identification Plate:

The watertight scuttle and watertight door for the contaminated clothing disposal locker will have a label plate reading "CONTAMINATED CLOTHING DISPOSAL LOCKER - KEEP TIGHTLY SEALED".

I-17 Outer Garment Removal Space (OGRS) Instruction Plate:

The Contractor will install the following aluminum embossed instruction label plates in the OGRS and showers that read as follows:

DO NOT REMOVE YOUR MASK UNTIL THE FOLLOWING PROCEDURES HAVE BEEN DONE:

· Prepare equipment, materials and the DECON Station for operation.

· Decontaminate mask and gloves with M-258 Decontamination Kit.

· Remove outer/protective garments and stow in plastic bags for disposal.

· Dispose of bags in the contamination clothing disposal (CCD) locker, taking care not to rip the bags. Ensure that the disposal locker scuttle is secured shut.

· Move from the Outer Garment Removal Space to the shower and at that point remove your inner garments. Continue to leave your mask on.

· Wearing only a mask, vigorously wash and scrub yourself using soap or detergent, especially those areas of the body where contaminants can lodge (under fingernails, skin cracks and crevices, hairy areas, etc.). Your mask’s filters must be shielded from direct spray during the shower.

· When the purge cycle is completed, remove the mask and let it fall into a plastic bag. Secure the bag with a tie, place it on the grating out of the way, and exit. You have completed the decontamination process.

I-18 Shower Instruction Plate:
