3. REQUIREMENTS

3.1 General.

3.1.1 CIR.

None.

3.1.2 Tech Rep.

Not applicable.

3.1.3 Protective measures.

3.1.3.1 The Contractor shall furnish and install suitable covering to seal off and protect all non-affecteed surfaces/equipment and spaces in the vicinity of the work area against contamination during the performance of work. Upon completion of work, remove protective material and inspect for the presence of contamination. Clean all equipment and spaces, contaminated due to improper protection, to original condition of cleanliness.

3.1.3.2 The Contractor shall abide by all lead and asbestos abatement compliance requirements, as specified in SFLC Std Spec 0000. Abide by the following additional safety precautions during the lead dust clean-up operation:

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 other areas with an 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; 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.

3.1.3.3 Remove protective covers, to allow for performance of lead dust cleaning and wipe sampling tasks, as specified in 3.2 (Clean-up particulars) and 3.3 (Clearance examination – post cleaning), respectively. Reinstall protective covers, after said tasks have been completed.

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

3.1.4 Interferences. The Contractor shall handle all interferences in accordance with SFLC Std Spec

0000, paragraph 3.3.5 (Interferences).

3.1.5 Certification requirements. The Contractor shall ensure that all contractors and subcontractors performing cleanup or sampling must possess all applicable Federal and state certification licenses for lead work and lead sampling. Submit documentation of these certifications to the KO within 48 hours prior to commencing work.

3.2 Clean-up particulars. The Contractor shall accomplish the steps provided below in each compartment designated for clean up.

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 lead contaminated debris by hand.

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

o Cleaning begins 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.

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

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

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 leaded 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.

3.3 Clearance examination – post cleaning. The Contractor shall accomplish the following tasks after completion of all cleaning operations:

3.3.1 Visual. Conduct a visual inspection, in the presence of the COR, to ensure that no chips, dust or cleaning material haze are present. Submit a CFR.

3.3.2 Wipe sampling. Conduct wipe sample clearance testing, in accordance with ASTM 6966, as designated by the Coast Guard Inspector, in ten locations for the designated compartment to ensure that there exist no lead dust residues in excess of 200 micrograms/square foot (mcg/ft 2). Submit a CFR with sample results

3.3.2.1 Ensure that lead dust samples are analyzed by a laboratory certified by the National Lead

Laboratory Accreditation Program (NLLAP) or the American Industrial Hygiene Association

3.3.2.2 If laboratory analysis shows lead concentrations in excess of the thresholds specified above, then perform lead dust cleaning, and take subsequent wipe samples until the concentration of lead falls below the above standards.

NOTE

For a listing of certified laboratories, go to www.aiha.org.

3.3.2.3 Be aware that the Coast Guard reserves the right to coordinate additional wipe clearance testing, at no cost to the contractor, to verify the sample results.

NOTE

All additional wipe clearance testing conducted by the Coast Guard must be witnessed by the Contractor, to verify where and how samples were collected

– and thus, prevent contract disputes.
