May 2012

Each building on the campus is generally a single-story structure. Buildings A, C, D and E (Alternate) contain attics and crawlspaces. Each building included in the project’s scope of work was observed with a reddish brown brick veneer exterior. Interior walls were either non-asbestos plaster on wood lathe or manufactured partition gypsum walls. Interior floors are generally wood or carpet applied over the wood flooring. However, several restrooms in Building A in the Principal’s office suite contained asbestos-containing sheet vinyl flooring and Office 15 in Building D contained asbestos-containing 9-inch by 9-inch floor tile and black mastic requiring removal. Ceilings systems throughout the campus ranged from nonasbestos suspended 2-foot by 2-foot or 2-foot by 4-foot composite panels, 16-inch by 24-inch (or 30-inch) tiles or 4-foot by 4-foot composited boards. Finally, attic spaces in each building were unfinished and contain HVAC ductwork and non-asbestos blown-in insulation. Forcedair heat pumps associated with the HVAC ductwork was observed along the perimeter of each building. Each building’s roof system was an “A-frame” roof and was covered with non-asbestos asphalt roof shingles and underlying felts. Perimeter window units in each building have been replaced with vinyl windows. The original boiler remains abandoned in Building A. A hot water/condensate return tank remains abandoned in Building E. Steam and condensate return pipelines remains abandoned in the crawlspaces of Buildings A, C, D and E and in steam pipe tunnels located throughout the campus grounds between affected buildings. Note: Lead-based and lead-containing paints have been previously identified applied in interior and exterior building components throughout the campus. Proper procedures and personal protective equipment (PPE) should be donned to prevent employee exposure during abatement and demolition activities. The Contractor will also be required to remove and dispose of generated waste materials sufficient to prevent contamination of soil at the site at the completion of demolition activities. PART 2

AIR SAMPLING STRATEGY ASHEBORO CITY SCHOOLS OLD BALFOUR SCHOOL 1738 NORTH FAYETTEVILLE STREET ASHEBORO, NORTH CAROLINA PROJECT NO. OLME-2012-07 1)

Ambient area, final area and personal air monitoring equipment will be calibrated at the start of and at the completion of each sampling period. In additional to performing ambient area air monitoring during the project, we will also obtain and analysis the personal air monitoring obtained by our Air Monitors and any obtained on Visitors to the site who may wish to enter the boundary of the Project.

2)

Background sampling will be obtained from locations inside and outside the Work Area in which asbestos-containing materials (ACM) are scheduled to be disturbed or will be transported during the project. The results of the background monitoring will help to establish preexisting airborne fiber levels for the Project in the planned work area boundaries. Typically these are obtained no more than one week prior to the start of the project in order to establish and document “presumed” similar conditions prior to the “Start-of-Work”.

3)

Our ambient and personal air sampling and analysis will be performed in general accordance with the National Institute of Occupational Safety and Health (NIOSH) Method 7400 using optical Phase Contrast Microscopy (PCM) as described in the specifications. This method of measuring airborne asbestos in buildings was developed by NIOSH in connection with the Occupational Health and Safety Administration (OSHA) asbestos exposure standards for the workplace. This method cannot distinguish asbestos fibers from non-asbestos fibers. Final area air clearance sampling will be performed utilizing TEM sampling and analysis procedures.

4)

The Contractor will be solely responsible for performing the required personal monitoring for his personnel as required by the specifications. The generally requires that personal monitoring be performed on at least 25 percent of the workers performing each type of job category. Typical monitoring time should be 60 to 120 minutes, however this could be reduced due to elevated amounts of airborne particulates being observed in the work area. The maximum flow rate for collecting personal samples should not exceed 2.0 liters per minute (l/m). A N. C. licensed Air Monitor obtain and analyze any air sample obtained during the project, to document personal expousre of employees.

5)

At a minimum, ambient area air sampling will be collected outside each of the work area(s) during abatement activities. Monitoring will be performed in adjacent, occupied areas in order to determine if the airborne fiber concrentrations outside each of the work areas on a daily basis is below 0.01 fiber per cubic centimeter of air. This also allows our Air Monitor with opportunities to walk around the jobsite and evaluate critical barriers and check for water leaks. We will inspect occupied areas located immediately below and adjacent to each work area to determine if water leak(s) may have occurred. This inspection will be carried out periodically during the day with outside supervisor of the contractor.

6)

The ambient area air sampling will also be collected inside each of the decontamination unit’s (DCU) clean room, equipment loadout’s clean room, at criteria barriers and accessible location(s) of negative air machine(s)’s exhaust.

AIR SAMPLING STRATEGY ASHEBORO CITY SCHOOLS OLD BALFOUR SCHOOL 1738 NORTH FAYETTEVILLE STREET ASHEBORO, NORTH CAROLINA PROJECT NO. OLME-2012-07

7)

If at anytime, the ambient area air sampling results collected outside or inside the Work Area is calculated to be greater than 0.01 fiber per cubic centimeter (f/cc), then the Contractor must cease abatement activities inside the work area and then must clean contaminated areas up to a ten (10) foot diameter or a distance as documented by the Air Monitor or SAM from the surrounding sampling location(s). Once cleaning is complete, additional air sampling in this area will be performed. If the additional air sampling results are calculated to be below 0.01 f/cc (or 70 structure per mm2), then the Contractor can resume the abatement work. If the ambient area air sampling results are greater than 0.01 f/cc, then the Contractor shall extend and reclean the contaminated area and recheck the seals of critical barriers adjacent to the contaminated area until the air sampling results are less than 0.01 f/cc (or 70 structure per mm2).

8)

There will be two blanks samples collected daily, a field blank and a laboratory blank. These blank samples must be reported along with the air samples collected each day. Samples submitted to the laboratory will be labeled with the following information: Sampling date, sampling location (or worker’s name and social security number), work activities performed during sampling, pump number, time on, time off, flow rate and the pump calibration data.

9)

The ambient area air sampling results must be made available to the Owner and Contractor at the “Start-of-Work” on the day following collection. The personal air monitoring results should be made available to the worker(s) after results are received by the Contractor. One copy must be kept at the jobsite for review.

10)

The will provide, as part of his Post-Job Submittals, the results of the personal air monitoring performed on his worker(s) during the project. A copy of the analysis results must be posted at the jobsite, perferably inside or near the DCU.

11)

The ambient area air sampling must be performed during each phase of work and from each area in which identified ACM are disturbed. The ambient area air sampling can only be terminated upon approval by the Designer.

12)

The ambient area air sampling obtained inside the work area shall be collected only while the Owner’s Air Monitor is inside the work area and is able to document the work activities.

13)

Negative air pressure inside the work area shall be observed and documented on a daily basis by the Air Monitor and the onsite Supervisor.

14)

Final area air sampling shall be obtained and analyzed using the AHERA regulations sampling and analysis protocol and an additional requirements as specificed in the Specifications after visual clearance has been achieved. Each floor (and/or work area) shall be treated as a separate phase of work and will require final area clearance sampling be performed utilizing PCM sampling and analysis protocol as per the AHERA regulations.

AIR SAMPLING STRATEGY ASHEBORO CITY SCHOOLS OLD BALFOUR SCHOOL 1738 NORTH FAYETTEVILLE STREET ASHEBORO, NORTH CAROLINA PROJECT NO. OLME-2012-07 15)

“Regulated” work areas in which less that 260 linear feet and/or 160 square feet of identified ACM is scheduled for removal shall be cleared using PCM sampling and analysis procedures. The samples will be analyzed using NIOSH 7400 Method. If the fiber level is less than 0.01 f/cc, then the area will be considered clean. If the fiber level is greater than 0.01 f/cc, the work area must be recleaned and final area clearance air sampling repeated at the Contractor's expense.

16)

OLME’s Supervising Air Monitoring (SAM) for the project will be Gary Alexander, N. C. Accreditation No. 90090.

SECTION 02082 GLOVEBAG REMOVAL PROCEDURES RELATED DOCUMENTS: Drawings and general provisions of the Contract, including General and Supplementary Conditions and other Specification sections, apply to work of this Section. PART 1

GENERAL

1.01

Glovebag procedures must be performed in strict compliance with OSHA requirements.

1.02

Prepare jobsite(s) per applicable articles for specified removal contained herein. Refer to Section 01563, entitled: "Decontamination Units" or Section 02100, entitled "Site Preparations".

1.03

Submit the Material Safety Data Sheet(s), or equivalent, in accordance with OSHA Hazard Communication Standard (29 CFR 1910.1200) for each surfactant and encapsulating material proposed for use on the Work. Include a separate attachment for each sheet indicating the specific Worker personal protective equipment (PPE) proposed for use with the material indicated.

1.04

Prior to asbestos abatement, the Abatement Contractor's equipment, Work Area and Decontamination Unit(s) will be inspected and approved by the Designer or his representative.

BEFORE STARTING THE PROJECT: 1.05

Two persons are required to perform the glovebag removal project. A third person is often helpful to assist with the supplies, to keep unwanted Visitors out of the Work Area, and to conduct the personal air monitoring. Each of the team members should have received training on the use and limitations of glovebag removal. They must also be participating in the abatement Contractor’s respiratory protection and medical surveillance programs.

1.06

Before any work begins, all necessary materials and supplies should be brought to the Work Area. This work area should be barricaded with asbestos warning tape and signs to minimize the chance of Visitors entering the Work Area. Remember -- never perform glovebag removal on hot pipes (over 150of). This may cause the glovebag or gloves to melt.

REMOVAL PROCEDURES: 1.07

Following the manufacturer's directions, mix the surfactant with water in the garden sprayer.

1.08

Have each Worker put on a half-face negative pressure dual cartridge respirator equipped with P-100 rated filters while inside the established regulated Work Area.

Asbestos Abatement and Demolition Project Asheboro City Schools Old Balfour School 1738 North Fayetteville Street Asheboro, North Carolina Project No. OLME-2012-07

May 2012

1.09

Have each Worker put on a full-body disposable suit. (Note: The hood goes over the respirator straps.)

1.10

Check the pipeline where the work will be performed. If it is damaged (broken, torn, etc.), wrap the pipeline in polyethylene plastic and "candystripe" it with duct tape. A common error when doing glovebag work is forgetting that loose pipe lagging several feet or even several yards away from the scheduled work may be jarred or loosen by the abatement activity. This is one of the common causes of high airborne fiber concentrations during glovebag removal. The other error is failure to preclean the schedule Work Area of debris on the floor and other surfaces that has accumulated prior to starting the work. If the pipeline is not damaged, it is still necessary to place one layer of duct tape around the pipeline at each end where the glovebag will be attached. This serves two purposes: A. B.

It provides a good surface to which to seal the ends of the glovebag, and It minimizes the chance of releasing fibers when the tape at the ends of the glovebag is removed upon completion of the job.

1.11

Slit the top of the glovebag open (if necessary) and cut down the sides to accommodate the size of the pipe (about two inches longer that the pipe diameter). One brand has a zipper top and straps at each end facilitating installation of the bag on the pipe.

1.12

Place the necessary tools into the pouch located inside the glovebag. This will usually include a bone saw, utility knife, rags, scrub brush, wire cutters, tin snips, and wettable cloth. (Note: It is easiest to precut the wettable cloth at this point.) Cut out a donut shape with the inner diameter of the pipe beneath the insulation. The outer diameter of the donut should be three inches longer than the diameter of the pipe insulation being removed. Finally, cut a slit in each of the donuts so they can be slipped around the pipe.

1.13

Place one strip of duct tape along the edge of the open-top slit of the glovebag for reinforcement.

1.14

Place the glovebag around the section of the pipe to be worked on, and then staple the top at intervals of approximately one inch through the reinforcing duct tape. Next, fold the stapled top flap back and tape with duct tape. This should provide an adequate seal along the top. Next, duct tape the ends of the glovebag to the pipe itself, previously covered with plastic or duct tape.

1.15

Using the smoke tube and aspirator bulb, place the tube into the water sleeve (two-inch opening top the glovebag. By squeezing the bulb, fill the bag with visible smoke. Remove the smoke tube and twist the water sleeve closed. While holding the water sleeve tightly, gently squeeze the glovebag and look for smoke leaking out, especially at the top and ends of the glovebag. If leaks are found, they should be taped and closed using duct tape and the bag should be retested.

1.16

Insert the wand from the water sprayer through the water sleeve. Using duct tape, tape the water sleeve tightly around the wand to prevent leakage.

1.17

One person places his hand into the long-sleeved gloves while the second person directs the water sprayer at the work.

1.18

If the section of pipe is covered with an aluminum jacket, removed the jacket by using the wire cutters to cut any bands and the tin snippers to remove the jacket itself. It is important to fold any sharp edges in order to prevent cutting the bag when it is placed in the bottom.

1.19

Use hand tools to cut the exposed insulation at each end of the section to be removed. Throughout this process water should be sprayed on the cutting area to keep dust at a minimum.

1.20

Once the ends are cut, the section of insulation should be cut into smaller sections. The initial cut should be made along the bottom of the pipe and water continuously supplied. Again care should be taken when using the knife not to puncture the glovebag.

1.21

Rinse all tools with water inside the glovebag and place back into pouch.

1.22

The insulation can now be lifted off the pipe and gently placed in the bottom of the bag.

1.23

Using the scrub brush, rags, and water, scrub and wipe down the exposed pipe.

1.24

Seal the exposed ends of the insulation.

1.25

Remove the water wand from the water sleeve and attach the small nozzle from the HEPAfiltered vacuum. Turn on the vacuum only briefly to remove the air from the glovebag.

1.26

Remove the vacuum nozzle and twist the water sleeve closed and seal with duct tape.

1.27

From outside the glovebag, pull the tool pouch away from the glovebag and twist it to separate it from the glovebag. Place duct tape over the twisted portion and cut the tool bag from the glovebag, cutting through the twisted/taped section and then seal with tape. In this manner, the contaminated tools may be place directly into the next glovebag without cleaning. At the end of use, place the tool pouch in a bucket of water and open under water. Adequately clean each tool and dried.

1.28

With the removed insulation in the bottom of the bag, twist the bag several times and tape the bag at the twist location keeping the insulation at the bottom of the glovebag.

1.29

Place the glovebag inside a 6-mil waste bag while still attached to the pipe. Cut the top of the bag from the pipeline and place it into the waste bag.

1.30

Remove disposable suits and place each inside the waste bag and seal.

Gooseneck seal each waste bag.

1.32

ACMs must be disposed of in an approved landfill in accordance with EPA regulations.

1.33

Air sampling should be conducted during and after completion of glovebag projects to determine if undetectable leakage has occurred. Sampling should be performed by qualified persons and immediate analysis provided. Once the area has been found to be safe for unprotected personnel, the barriers may be removed and reinsulation can commence.
