3. Training in emergency response and evacuation procedures shall be provided.

B. Respiratory Protection

1. All respiratory protection shall be provided to workers and maintained in accordance with the contractor’s written respiratory protection program, which includes all items in OSHA 29 CFR 1910.134 (b) (1-11). This program shall be posted outside of the clean room of the worker decontamination enclosure system.

2. Workers shall be provided with individually identified (marked with waterproof designations) respirators.

3. Contractors shall use available historical data to perform an initial exposure assessment prior to the initiation of abatement activities. The minimum level of respiratory protection allowed during abatement activities shall be Powered Air Purifying Respirators unless and until air sampling and laboratory data support the use half-mask air purifying respirators which will then be the minimum allowable respiratory protection for the removal and cleanup phases of this project.

C. Fit Testing

1. Workers must perform positive and negative pressure fit tests each time a respirator is put on, whenever the respirator design so permits. Powered air-purifying respirators shall be tested for adequate flow as specified by the manufacturer.

2. Workers shall be given a qualitative fit test in accordance with procedures detailed in the OSHA Standard (29 CFR 1926.1101, Appendix C, Qualitative Fit Test Protocols) for all respirators to be used on this abatement project. An appropriately administered quantitative fit test may be substituted for the qualitative fit test. NOTE:

All respirators used on this project must have the capacity to function safely in the negative pressure mode, so as to insure a level of respiratory protection, in the event of battery pack, AC power, or compressor failures.

3. Documentation of adequate respiratory fit testing must be provided to the Engineer.

3.4 ABATEMENT PROCEDURES

A. Gross Removal and Decontamination within Negative Pressure Enclosure

1. Clean and isolate the work area as specified herein.

2. Wet all asbestos containing material with an amended water solution using equipment capable of providing a fine spray mist, in order to reduce airborne fiber concentrations when the material is disturbed. Saturate the material to the substrate, however, do not allow excessive water to accumulate in the work area. Keep all removed material wet enough to prevent fiber release until it can be containerized for disposal. It is important to maintain humidity in the work area (by misting or spraying) to assist in fiber settling and reduce airborne concentrations. Wetting procedures are not equally effective on all types of asbestos-containing materials, but shall nonetheless be used in all cases.

3. Saturated asbestos containing material shall be removed in manageable sections.

Removed material shall be containerized before moving to a new location for continuance of work. Surrounding areas shall be periodically sprayed and maintained in a wet condition until visible material is cleaned up.

4. Containers (6-mil polyethylene bags or drums) shall be sealed when full. Bags shall not be overfilled. They shall be securely sealed to prevent accidental opening and leakage by tying the tops of the bags in an overhand knot or by taping in gooseneck fashion. Do not seal the bags with wire or cord. Bags shall be decontaminated on exterior surfaces by HEPA vacuuming and wet cleaning before being placed in clean drums or bags in the waste decontamination pass-out enclosure.

5. For drywall and joint compound removal only, the Contractor may elect to line the interior of the dumpster with polyethylene sheeting to create a “bladder bag” on the interior of the dumpster. Waste materials may be placed directly within the lined dumpster in lieu of bagging the materials as long as the route of access is adequately protected.

6. Large components removed intact may be wrapped in two layers of 6-mil polyethylene sheeting secured with tape for transport to the landfill.

7. Asbestos-containing waste with sharp-edged components (e.g. nails, screws, metal lath, tin sheeting) will tear polyethylene bags or sheeting, and thus must be placed in drums and/or burlap bags for disposal.

8. After completion of all stripping work, surfaces from asbestos containing material have been removed shall be wet-brushed and sponged or cleaned by some equivalent method to remove all visible residue.

9. Clean-up shall proceed in accordance with Section 3.5.

B. Glovebag Removal within a Regulated Area

1. All glovebag removal activities shall be performed within a mini-enclosure within a regulated area. Glove bag procedures for the removal of thermal system insulation shall be conducted using commercially available glove bags of 6-mil clear polyethylene or equivalent, appropriately sized for the project.

2. Prior to performing glove bag removal procedures, the work area shall be isolated to restrict access of work areas to non-abatement personnel. Warning signs and caution tape shall be posted at the entrances to the restricted area in order to avoid any accidental entry into the work area.

3. Each work area where glovebag operations are to be performed shall be pre-cleaned prior to the initiation of removal activities.

4. Remote decontamination facilities shall be constructed consisting of at least a clean room, shower room, and equipment room within a reasonable proximity to the Work Area as approved by the Consultant.

5. Glovebag removal procedures shall be done by a minimum of two licensed asbestos workers trained in glovebag removal procedures and equipped with respiratory protection and two disposable coveralls.

6. All necessary tools shall be brought into the regulated area prior to the initiation of glove bag removal procedures.

7. Glovebags shall be sized to adequately fit the diameter of thermal system insulation to be removed. Do not attempt to use a glove bag on piping hotter than 150 degrees F.

8. Glovebag removal procedures shall be performed as follows:

a. Place all the tools and material necessary to remove and seal the covering in the tool pouch or in the bottom of the bag.

b. Attach the glove bag around the pipe and seal the ends of the glove bag securely to the pipe utilizing duct tape to create an airtight seal. The integrity of the seals shall be tested by smoke testing prior to the initiation of removal.

c. Make a small hole in the center of the bag just below the pipe (6 inches) and insert the water sprayer. Seal this hole airtight with tape. The subject thermal system insulation shall be misted with amended water prior to and during removal activities.

d. Use tools to cut existing wires, bands, or metal jacketing. Care must be taken when removing these to avoid ruptures of the bag from the sharp edges. The material removed should be gently placed on the bottom of the bag to avoid rips and tears.

e. Cut the ends of the insulation and slit lengthwise to remove insulation from the associated pipe.

f. Spray unprotected pipe with amended water and use tools to fully remove any residual dust and debris from pipe surfaces.

g. Seal exposed ends of insulation with bridging encapsulant or duct tape.

h. Spray tools and amended water to clean and place tools within the one of the rubber gloves.

i. Turn the glove inside out and twist and twist and seal end of glove from the inner portion with duct tape. Sever the center of the duct tape to create two separate bags.

j. Remove the water wand and replace it with the HEPA vacuum. Seal the hole and collapse the bag with the vacuum. This will create negative pressure in the bag and help reduce tears and leaks.

k. Twist the glove bag several times and seal the connection with duct tape.

l. Place a 6-mil polyethylene disposal bag under the glove bag, remove the tape, and place the sealed glovebag into the disposal bag.

C. Non-friable Removal within a Regulated Area

1. All asbestos-containing expansion joint caulk removal activities shall be conducted to the exterior of the building in accordance with applicable federal, state, and local

2. Restrict access of work areas to non-asbestos abatement personnel and regulate the work areas utilizing warning signs and/or caution tape.

3. Place 6 mil polyethylene sheeting on the ground outside the abatement areas to catch any debris generated during removal activities.

4. Wet expansion joint caulk with an amended water solution using equipment capable of providing a fine spray mist to reduce airborne fiber concentrations when the material is disturbed.

5. Using manual methods, remove any expansion joint caulk adhered to the exterior systems in one piece (to the extent feasible). Removal methods shall employee the use of wet methods and HEPA vacuuming to ensure that materials are not rendered friable.

6. Place all ACM waste in a lined dumpster for disposal. The Contractor shall take efforts to ensure expansion joint caulk is not dislodged during material handing activities and shall clean any debris generated.

7. Utilize HEPA vacuums and wet methods to clean debris off of horizontal surfaces and on remaining polyethylene sheeting. Dispose of polyethylene sheeting and debris in the lined dumpster.

3.5 CLEAN UP PROCEDURES

A. Clean-up Procedures Shall Include the Following:

1. Remove and containerize all visible accumulations of asbestos containing material and asbestos contaminated debris utilizing rubber dust pans and rubber squeegees to move material around. Do not use metal shovels to pick up or move accumulated waste. Special care shall be taken to minimize damage to floor sheeting.

2. Wet clean all surfaces in the work area using rags, mops, and sponges as appropriate. To pick up excess water and gross wet debris, use a HEPA wet-dry vacuum.

3. The Contactor shall ensure that all mastic removal and cleaning activities are performed in accordance with manufacturer recommendations and applicable regulatory requirements. The cleaning of concrete floors shall be performed utilizing a three-phase cleaning process (initial, second and third clean).

4. The negative pressure ventilation units shall remain in continuous operation.

Decontamination enclosure systems shall remain in place and be utilized.

5. After cleaning the work area, wait until all the surfaces become dry to allow fibers to settle and HEPA vacuum and wet clean all objects and surfaces in the work area again.

6. Remove all containerized waste from the area and waste container pass-out.

7. Decontaminate all tools and equipment and remove at the appropriate time in the cleaning sequence.

8. Inspect the work area for visible residue. If any accumulation of residue is observed, it will be assumed to be asbestos and the settling period/cleaning cycle repeated.

9. The work areas shall be cleaned until the Owner and/or the Engineer has determined that the results of his visual inspection are satisfactory. Clearance air testing will be passed when laboratory results indicate airborne fiber concentrations of less than or equal to 0.01 fibers per cubic centimeter (using phase contrast microscopy) or 70 structures per square millimeter (using transmission electron microscopy) at all sampling locations. Sample methodology and clearance criteria shall meet regulatory and specification requirements as identified herein. Additional cleaning cycles shall be provided, as necessary, at no cost to the Owner/Engineer until these criteria have been met.

10. Following the satisfactory completion of clearance air monitoring, the remaining barriers may be removed and properly disposed of. A final visual inspection by the Engineer shall insure that no contamination remains in the work area. Unsatisfactory conditions may require additional cleaning and air monitoring which shall be performed at the Contractor’s expense at no additional cost to the Owner.

11. All HEPA filtration units shall remain in operation until the containment has successfully…
