It is always the goal to achieve the minimum level attainable. A review of nu merous asbestos removal contracts have indi cated "clean air" is achieved anywhere from "no asbestos" to 2 fibers per cubic centimeter of air sampled (flbers/cc). The later being the current Occupational Safety and Health Admi nistration (OSHA) Asbestos Standard (29 CFR 1910.1001). The OSHA level is clearly not ade quate to be used for this purpose. Likewise, "no asbestos" cannot be measured accurately, and asbestos fibers are normally present in the am bient air, although at very low concentrations. Many contracts specify the contractor must attain a cleanliness level in a range from 0.01 to 0.05 fiber/cc. Studies conducted by Georgia Tech and others have found the `typical" fiber concentration in most buildings containing sprayed-on asbestoscontaining materials is 0.02 fibers/cc or less. Accordingly, "clean air" specifications should not be higher than the level prior to the abate ment project. Therefore, the clearance air sampling results should be less than 0.01 flbers/cc. If 0.01 fibers/cc is specified, the air sampling scheme should reflect this and pro vide reliable results. If the National Institute for Occupational Safety and Health (NIOSH) method P & CAM 239 is followed exactly the sampling volume should be Increased to 960 liters. If no fibers are found by the analyst, the resulting concen tration reported (95% confidence limits for most microscopes) should be less than 0.003 0.007 fibers/cc. If only 240 liters are sampl ed (minimum volume stated in many con tracts and the EPA Guidance Documents), the resulting limit of detection would be less than 0.02 0.08 fibers/cc. This should not be con sidered adequate for clearance sampling. Currently, several alternative methods of extending the limit of detection to lower levels are being evaluated. These include examining a larger area of each filter, using a filter of smaller size (diameter) and an increased flowrate. Until these modifications to the NIOSH method have been validated their use should be with reservation. Submitted to the NAC NEWSLETTER by William M. Ewing, Industrial Hygienist, Georgia Institute of Technology, Engineering Experiment Station, Environmental Health and Safety Division, Atlanta, GA 30332. NEW YORK LEGISLATURE CONSIDERS ASBESTOS BILL On March 1, bills relating to asbestos safety in public buildings were introduced in the New York State Senate and the Assembly. The le gislation (S. 3645, A. 4727) is before the Com mittee on Government Operations in both houses. If passed, the bills would amend New York State's public buildings law by requiring the Commissioner of General Services to: inform users of public buildings of health hazards of all asbestos materials, especially those in a damaged, deteriorated or disturb ed state; provide information of a scientific and technical nature to persons responsible for maintenance of buildings suspected of con taining asbestos and constituting an immi nent health hazard; require persons responsible for mainte nance to inspect all public buildings and report the existence of damaged, deterio rated or disturbed asbestos materials; maintain records regarding asbestos materials in public buildings; establish work guidelines: establish training programs for contractors: adopt minimum levels of asbestos air con centration in such buildings: and. explore other activities to eliminate health hazards caused by asbestos. BOMA/New York will be following the legis lation closely to determine whether it could ef fect privately owned office buildings. (Reprinted from BOMA International Skylines.

An O&M plan should be: Definitive with respect to inspection results (and adequate testing) specific to each building. Where are the asbestos-containing materials located? Provide building plans and testing results. Specific with respect to warning systems. What are the alert signals utilized in the building? Do all persons utilizing the build ing understand the signs being used? Can warnings be restricted to certain class of employees, such as maintenance men? Ade quate warning is the issue. Notification oriented. Timely programmed instruction for relevant parties, with periodic testing for its ade quacy. is essential with regard to: 1. Orientation to the building and the loca tion of hazards. 2. Provision of safety equipment adequate for anticipated work. 3. Professional training regarding work practices and worker protection pro cedures. 4. Supervision requirements, emphasizing building owner policies and legal liabilities. 5. Medical surveillance, given evidence of exposure to hazards. Remedial Measure Oriented. A plan of action should be provided to delineate the building owner's policies (strategy, objectives, schedules) regarding the specific engineering measures to be undertaken to provide a remedy for hazards in the building. Tasks for building owner employees should be clarified with respect to those tasks that are to be left for outside specialist support. Further, decision-making guidelines should be provided for unan ticipated circumstances. Couched in a Managerial Control Context. Policies can be as hazardous as any material contained in a building, therefore, managerial control concepts are essential from both financial and legal viewpoints. Cost recovery and tort claim defense are vital aspects of the O&M plan. Competent professional (specialist) advice and guidance can be appropriate in both the formulation and implementation of an O&M plan. Competent legal advice is byfar the most important aspect of managerial control, given the need for an asbestos hazards program.

The room was filled with a water mist to wet down the fi bers so they could be removed. The project took about three days and is expected to cost the school district *13,800. The asbestos was being re moved as a result of a study conducted early this year which found that asbestos fibers used to insulate pipes in the boiler room were being circulated though the school's ventilation system. The district decided to remove the asbestos to avoid any possi ble health hazard. Asbestos has been linked to lung cancer and lung inflammation. John Dolak, who is in charge of business affairs for theUloliet Public Grade School District, said the ventilation system was turned off last spring to limit circulation of the fibers until they could be removed. Dolak said the asbestos fibers were part of a blown-in type of insulation. He said no other school in the district used this type of insulation.

Spain, CIH, CSP NAC Board Member ALCOA0000009101 "ASBESTOS ABATEMENT & THE NEGATIVE AIR CONCEPT" Mr. Rick Lutterbach, veteran asbestos abatement contractor of over 500 projects was one of the first environmental control engineers to develop and utilize the theory of negative air pressure on asbestos abatement projects. His "on the job" research was Instrumental in the design and development of the Ultlmate-Aire "Hog 4000"; a complete negative air system for asbestos projects. The following Interview for the National Asbestos Council will provide an swers to some common questions asked by As bestos Abatement Contractors concerning the negative air pressure concept. Mr. Lutterbach Is President of Control Resources Corporation, a national asbestos abatement firm, head quartered in Michigan City, Indiana. NAC: What is the negative air concept? ANSWER: Basically the typical abatement project has a series of air locks between the contaminated work zone and the non-contaminated area. The use of negative air is simply creating a pressure drop in the contaminated area thus creating an air flow into the work zone from the non-contaminated area. NAC: How is negative air actually accom plished? ANSWER: Specifically, every project has its own personality, therefore we must speak In generalities. Negative air is accomplished by strategic placement of Air Alteration equip ment in the contaminated area. A machine, like the "HOG 4000" is placed opposite to the decontamination chamber. Contaminated air is drawn through a series of filters, including a HEPA filter and is exhausted through a mani fold attached to a 12 inch diameter flexible hose. This hose ports through a template In an exterior window or door. When sufficient equipment is utilized, a tremendous air flow is exhausted out of the building 99.97% clean. NAC: Why is negative air necessary on an asbestos abatement project? ANSWER: There are several reasons, all of equal importance, so 1 will address them Individually. (1) General Safety: Plasticizing and de contamination barriers are subject to many variables such as human error, improper methods, faulty taping, un usual construction and many areas where there is potential for accidental contamination to clean areas or live ad jacent environments. Negative air is like an insurance policy against the many possible sources of air leaks. Air is drawn through the decontamination chamber and Is also scavenged through all existing air leaks which have not been plasticized correctly. Lets face bare facts, 1 have not seen an asbestos abate ment project yet that could be consid ered air-tight. Negative air makes this a reality. (2) Type "C" Respiratory Environ ments: In addition to the aforemen tioned general safety, the utilization of supplied air to asbestos workers on pro jects adds an additional hazard to the ad jacent clean area or live environment. The typical Type "C" supplied air system is supplying 15-30 cfm of air to the worker. Simple mathematics shows you that positive air pressure is being ex hausted in the contaminated area thus forcing asbestos fibers through the de contamination area and into the clean zone through any available air leaks. There is no question in my mind that utilizing Type "C" systems without compensating negative air equipment is an unacceptable procedure and en hances the possibility of gross con tamination of areas outside the work zone. (3) Worker Comfort A Productivity: The typical abatement project is very humid and hot. Productivity of the worker decreases substantially when the out side temperature rises. Encapsulants fail to cure properly, tape adherence fails, etc., etc. Negative air creates a constant inflow of cooler less humid air into the work zone. This air flow decreases hu midity and temperature thus eliminat ing heat stress and increasing worker productivity. (4) Pinal Certification: The moment every abatement contractor and client waits for is the final air monitoring re sults to certify his work area is clean of asbestos fibers. It's ironic how much time is spent on cleaning walls, floors and HEPA vacuuming all surfaces when no time is spent on cleaning the air. An asbestos fiber, as we all know, is aerody- namically inclined to suspend itself in the environment for quite some time. Cleaning surfaces and not the air has led many abatement contractors to rather lengthy certification periods. The use of the negative air concept will completely exchange and clean the air in a con taminated zone approximately 96 times in a 24 hour period. A certain method to achieve a clean bill of health and speedy certification. IContinued on next page.) ALCOAOOOOOQ9102 NAC: Is there a recommended formula for establishing adequate negative air pressure? ANSWER: We have found as a general rule that utilizing adequate negative air equipment to insure a complete exchange of air by volume in the work area every 15 minutes in sures a good clean and safe project. We have tested and researched this ratio on many pro jects with varying concentrations of asbestos and differing types including amosite with satisfactory results. NAC: How do we know that the air being ex hausted to the outside is actually free from asbestos? ANSWER: There are very few negative air pressure systems on the market today. I can only speak on behalf of the system that I assisted in designing. The "HOG 4000" has a series of filters including a HEPA that has been tested and meets the NIOSH standards for effi ciency. The blower and seals for the filter housing has been similarly tested to check for possible bypass of unflltered air. In addition the "HOG 4000" has been field tested to assure that asbestos fibers in the exhaust air are minimized. In retrospect the answer to the question is to use quality tested equipment. In summation, negative air and asbestos abatement are synonymous in my opinion. There is more to the entire concept than our brief interview can expose. As a NAC member, I encourage our membership to investigate this concept more extensively to insure safety for themselves and their clients.

LETTER TO THE EDITOR: Editor: We totally agree with Stan Shaw's fine arti cle on asbestos in private homes in Volume 1, Number 1. Our own recent experience with residential types of problems includes: 1. A woman who had an "Armstrong" type floor removed, scrapped and sanded: then she vacuumed the house. Fortunately the floor tile did not contain any asbestos, but she was quite hysterical after she had call ed all federal agencies and finally found us in the yellow pages. 2. Another owner sent in fiber glass insula tion and was quite over wrought when we said there was no asbestos. 3. A condominium containing 100 buildings had chrysotile (30-45%) in the attic areas where residents stored their belongings and had frequent contact. The boiler room and maintenance areas were in a similar asbestos condition. These types of cases support that Stan has stated. We need to participate in the develop ment of guidelines for private residences and commercial buildings. Rumors are circulating in Washington that EPA plans to do this, this summer, but professional guidelines from the NAC would be most deslreable in helping pro mote this possibility.
