Add new paragraph A2.2.5.3.3 Additional requirement during lead-containing paint abatement, as follows:

A2.2.5.3.3 Additional requirements during lead-containing paint abatement. Abide by the following additional requirements, during work that involves disturbance or abatement of lead-containing paint:

A2.2.5.3.3.1 Protective measures.

A2.2.5.3.3.1.1 Abide by the following additional safety precautions during the lead dust clean-up operation (see

A2.2.5.3.3.3 Post-surface preparation cleaning, inspection, and sampling):

Separate contaminated areas from other areas.

Do not permit non-essential personnel in the work area.

Work in one compartment at a time.

Prevent dust from migrating to other areas, as follows:

o Seal doors, hatches, and all other openings between the work area and other areas with an

5 (Rev-0) airtight barrier, such as fire-rated polyethylene; seal both sides (inside the construction area, and inside the adjacent area) to provide a secondary dust barrier and prevent the doors and windows from being used (post alternative emergency exits, if applicable).

o Ensure that the work area remain under negative pressure in relation to adjacent areas.

NOTE

Negative pressure means that more air is exhausted from the area than is supplied so that lead dust and asbestos particles are contained within the work area, and do not contaminate adjacent non-affected compartments. Exhaust air must be filtered with a suitable HEPA filter.

Take, at a minimum, the following measures, to protect de-contamination workers:

o Use a HEPA (high-efficiency particulate air) vacuum - never use a conventional vacuum. A

HEPA vacuum removes 99.97% of particles that are less than 0.3 microns in size.

o Never use compressed air; never dry sweep.

o Workers must wear a respirator which is approved by NIOSH and has N100, P100 or R100 filters (the cartridges are usually purple); respirators must be fit-tested to insure proper seal, and employees must be medically screened and trained prior to wearing a respirator (see the

OSHA Respirator Standard, 29 CFR 1910.134).

o Workers must wear full-body protective clothing, head covering and shoes (or shoe covers).

o Workers must not leave the work area without having gone through a proper decontamination process, to prevent spread of lead dust to un-affected areas.

o Eating, drinking and smoking are prohibited in work areas.

o Workers must wash hands and face before eating, drinking or smoking.

o Workers must remove work clothes and shoes before leaving the work area, and seal work clothes in plastic.

o Workers must shower and wash hair as soon as possible after leaving the work area.

o Non-disposable work clothes must be washed separately from other clothes.

A2.2.5.3.3.1.2 Remove and dispose of all protective covers, upon completion of work.

A2.2.5.3.3.2 Spot lead coating abatement. When lead-containing coating, has been identified either in a particular work item or via a CFR as interference to work (including but not limited to hotwork, equipment and component installations, structural repairs, or ultrasonic thickness measurements), do the following:

A2.2.5.3.3.2.1 Coating removal/surface preparation. Remove existing lead-containing coating in affected areas, using one or a combination of the cleaning methods specified in Table A1 below, as applicable. Ensure that all power tool equipment have suitable vacuum attachments, to capture all generated coating lead dust.

TABLE A1

MECHANICAL CLEANING CHEMICAL STRIPPING

Steel surfaces: Power tool clean to a SSPC-SP

11 (1.0 mil anchor profile).

Use a suitable chemical stripper to safely remove all existing coatings – and

6 (Rev-0)

Aluminum surfaces: Power tool clean, using suitable power sanders and abrasive sandpaper with no metallic contents, to remove all existing coatings and rust spots, down to bare metal.

expose the bare substrate, in accordance with manufacturer’s instructions.

Known paint strippers meeting the requirements specified in Table A1 include, but are not limited to the following:

1. Franmar LeadOut

2. STRIP-TOX Paint Stripper

3. Aquastrip ACB

4. Smart Strip™ Advanced Paint Remover:

WARNING

Paint stripper must be formulated without methylene chloride, chlorinated solvents, phenols, chromates, ammonia or amines.

A2.2.5.3.3.2.2 Waste Disposal. Sample and dispose of generated waste, in accordance with all applicable

Federal, state, and local regulations.

A2.2.5.3.3.3 Post-surface preparation cleaning, inspection, and sampling. Upon completion of any surface involving removal of lead-containing coating (whether during spot abatement or full abatement), do the following, as applicable:

A2.2.5.3.3.3.1 Lead dust clean-up. Clean all lead dust from the worksite by suitable clean-up cleaning methods, or as follows:

Step 1 - debris removal: Remove all gross debris, paint chips, etc. using either a vacuum with a

HEPA filter or by spraying the materials with water in a spray bottle and picking up chips or large pieces of contaminated debris by hand.

Step 2 – vacuum cleaning: Using a suitable HEPA vacuum, clean all affected surfaces, in accordance with the following guidelines:

o Begin cleaning with high areas first – with overhead surfaces and bulkheads working downward.

o Vacuum all surfaces in the compartment.

o Work in the direction furthest from the entry door toward it.

Step 3 – wet cleaning: Following thorough HEPA vacuuming, wash all surfaces with any suitable cleaning detergent following the same cleaning pattern (high to low/ furthest from and toward entrance). Change the cleaning solution as it becomes dirty. Rinse all areas with a fresh cloth/mop.

Do not reuse contaminated mops and cloths. Use a three-bucket system for cleaning. (Detergent solution in first bucket/ rinse water for mop in second/ surface rinse on deck and/or bilge surfaces in third).

Step 4 – vacuum cleaning: Perform a HEPA vacuum again as specified in “Step 2”.

Step 5 – waste disposal: Properly dispose of contaminated materials, in accordance with all applicable Federal, state, and local regulations.

7 (Rev-0)

NOTES

1. Work Wet, Work Smart, and Work Clean. DO NOT GENERATE DUSTS. It is easier to effectively clean an area when dusts are not being generated to resettle on previously cleaned areas! Worker exposures may be high during wet sweeping.

2 A wet/dry HEPA unit is ideal for working with hazardous dust clean up.

3. Lead-contaminated objects that are porous or materials that may suffer damage from water may not be able to be sufficiently decontaminated by these methods and should be discarded.

A2.2.5.3.3.3.2 Visual inspection. Conduct a visual inspection, in the presence of the Coast Guard Inspector, to ensure that none of the following is present:

Visible coatings on any part of the substrate, including pitted areas.

Dust (as applicable).

Cleaning material haze.

A2.2.5.3.3.3.3 Post-lead abatement clearance. Upon acceptance of the visual inspection results by the COR, do the following:

A2.2.5.3.3.3.3.1 Wipe sampling.

A2.2.5.3.3.3.3.1.1 Conduct wipe sampling clearance testing, in accordance with ASTM 6966, as designated by the Coast Guard Inspector, in three locations in the affected space, to ensure that there exist no lead dust residues in excess of the below-listed concentrations, as specified below. Submit a CFR with sample results

40 micrograms/square foot (mcg/ft 2) - for berthing and/or food preparation areas.

200 micrograms/square foot (mcg/ft 2) - for all other areas.

A2.2.5.3.3.3.3.1.2 If a Change Request (CR) has been authorized and released, conduct wipe sampling clearance testing in additional locations, as designated on the CR.

A2.2.5.3.3.3.3.2 Laboratory analysis. Ensure that dust lead samples are analyzed by a laboratory certified by the
