Dear Janis:
I have your letter of September 9 along with your completed AIA Dust Measurement Record for 1990. Please disregard my tracer mailing to you and others which went out just yesterday.
You have made some excellent points regarding the current format of the DMR and the fact that it does not allow for short term exposure limit exposures which will skew the data reported. I will pass your comments along to the Asbestos International Association with the confidence that it will be revised accordingly.
Also, I have advised LHCF of the addition of Mr. Case and Ms. Bixby as participants in the current asbestos fiber counting trial.
As always, many thanks for your excellent coorperation and assistance.
Sincerely,
B. Pigg President

Dear Bob:
Attached is our completed AIA Dust Measurement Record (DMR) for 1990. As in the past, this information covers our only remaining A/C pipe plant.
I do have one concern in reporting this information. As you stated in your letter (dated 8/7/1991) this information is used to demonstrate that worker exposures to asbestos dust continue to decline. Overall, I agree that asbestos exposures are declining, however I am not sure that the information provided in this format is an accurate indicator.
As I am sure you are aware, OSHA with the last revision of the asbestos standard, October 1988, amended the standard by adding an excursion limit (EL) of 1 f/cc over a 30 minute sampling period. This short term monitoring is required whenever the asbestos concentration will not be uniform throughout the workday and high concentrations of asbestos reasonably may be expected to be released or created in excess of the EL.
To comply with this regulation, we at CertainTeed collect samples during our routine and preventive maintenance projects, which include entering the bag opener and dust collectors. During these jobs our employees are adequately protected using full face HEPA filter respirators and Tyvek coveralls. In most cases, during these excursion level projects the samples become extremely overloaded and uncountable. Those that can be effectively analyzed result in excessive levels. These results are included in the worker's time weighted average (TWA), thus increasing the 8-hour exposure considerably.
These types of preventive maintenance projects will always be accomplished in our plant, and will always result in higher fiber concentrations, thus skewing the data for normal day to day manufacturing operations.
CTD026103
Mr. B. J. Pigg September 9, 1991 Page 2
I'm sure other participating companies in the U.S. are aware of
this situation, however, I'm not sure the international members
collect samples in the same manner. Perhaps a more thorough
questionnaire would take into consideration this excursion limit
problem and help to better classify this information.
As a
minimum, I suggest that TWA's containing excursion limit
samples, primarily maintenance operations, be classified
separately.
As an added note, I have received the slides for this years fiber counting trial. Three of us will be participating in this trial, myself and two new industrial hygienist. Their names were not originally included on the registration form sent to LHCF in May. They are Mr. Tom Case and Ms. Martha Bixby.
Thank you for including CertainTeed in this survey and the fiber counting trial.

Memorandum For:
AIA/NA Members (less Canadian Producers)
Subject:
Dust Measurement Record (DMR) 1990 (Asbestos International Association)
Please find enclosed a copy of the Asbestos International Association's (AIA) letter dated July 29, 1991 and attachments thereto.
It will be recalled from previous efforts of this nature that the AIA, with approval of its Governing Council, has collected data on dust levels in factories and mines and mills from companies belonging to national associations that are members of the Asbestos International Association. Surveys were conducted for the years 1983-1989. This survey applies to 1990.
It is understood that the asbestos producers in Canada will be participating in this survey through The Asbestos Institute.
AIA/NA members and other interested companies that have participated in prior surveys include the following for which sincere appreciation is extended:
Allied-Signal (Bendix) CAPCO Pipe Company CertainTeed DISTEX Durabla Ferodo America Henry Company
Grundy Industries KCAC Monsey Products Supradur Vermont Asbestos Group
Accordingly, AIA/NA members (less Canadian producers) are requested to give close attention to the enclosures at your earliest convenience. Return of the AIA DUST MEASUREMENT RECORD (DMR) 1990 to this office by September 24, 1991 would allow for collation and transmission to AIA within the timeframe requested. One of the principal
RECEIVED
AUG 12 1991
CTD026116
page 2 uses of this survey is to demonstrate before various international bodies and forums that worker exposures to asbestos dust continue to decline as a result of responsible efforts by the asbestos industry. By copy of this memorandum, we invite and encourage companies who are not members of this Association, but have made financial contributions to our work, to participate in this important survey. Thank you in advance for your assistance. Please let us know should you have questions or if we can be of help in any way.

ANNEX TO 1990 DMR FORMS
NOTES EOR GUIDANCE WHEN COMPLETING THE DUST MEASUREMENT RECORD
(DMR)
The DMR is confidential and only an AIA composite report will be made public. Individual factories and companies will not be disclosed. The total workforce referred to in Question 1 should include all personnel on the pay roll including: office staff, etc. The "workers under survey" referred to in question 1 are the number of workers to whom an exposure index is assigned in the factory records. The enquiry about laboratory control schemes referred to in question 6 reflects the importance of this issue and all laboratories carrying: out analysis should take part in a well constructed scheme. The AIA counting trial is available to all AIA member associations. The table 8 requests information about the monitoring data obtained over the year :
- Personal samples are intended to monitor exposure or individual persons and tire attached to the person being monitored. - Static samples are used to measure general dust levels and are used for engineering control purposes. - The column headed "Workers in the Class" refers to the number of persons allocated to each class of measurement. For instance if a sample is taken to represent a work group of 10 persons, because their work practices are identical the entry should be 10 and not 1. Considerable care is necessary when deciding upon group representation of this - nature. Most workers have individual work practices which greatly influence exposure. If there is good reason to report results in section (8) as separate groups, e.g. persons working only with glass wool and no asbestos etc. then it is permissible to submit that group on a separate and full recorded sheet.
