Dear "Calidria" Asbestos Customer:
As part of our continuing effort to emphasize the importance of keeping you, your employees and your customers advised of the best practices for using asbestos safely, we are enclosing herewith a copy of our Material Safety Data Sheet for "Calidria" Asbestos, dated September 1, 1976. Additional copies are available from this office upon request.
In addition, we are enclosing copies of two pamphlets published by the Asbestos Information Association/North America (AIA/NA) as follows: "What You Should Know About Asbestos and Health" and "Recommended Practices for Handling Asbestos Fiber." Also enclosed is a listing of other published material available from AIA/NA. Copies of AIA/NA material may be obtained directly from AIA/NA.
Please advise each of your employees who handles our "Calidria" asbestos that you have such safety data sheets available for reference and deliver to them the foregoing pamphlets for their information and protection. If you do not receive sufficient pamphlets so that each employee handling "Calidria" asbestos will receive one copy of each pamphlet, we will be happy to furnish you with additional copies.
We are also concerned that your customers and ultimately their employees be kept informed by you of the best safety practices for using your products containing asbestos.
We would like to express our appreciation for your business. Please let me know if we can serve you better in any way.
Very truly yours.

BOILING POINT AND MELTING POINT: Not Pertinent SPECIFIC GRAVITY (HzO = 1): 2.45 VOLATILE CONTENT: Absorbed Water 1 -- 4% By Weight. Structural Water Approximately 13% by Weight. APPEARANCE: Pellets or Fine White Powder. No odor. Very Slight Solubility in Water.
II. HAZARDOUS INGREDIENTS
Asbestos contains no hazardous ingredients. However, the material itself can be hazardous under certain conditions. (See V below.)
III. FIRE AND EXPLOSION HAZARD DATA
NON-COMBUSTIBLE MATERIAL: No Fire or Explosion Hazard.
IV. REACTIVITY DATA
INERT MATERIAL: No Decomposition or Polymerization Conditions.
V,HEALTH HAZARD DATA
PERMISSIBLE EXPOSURE TO AIRBORNE CONCENTRATION: The current Occupational Safety and Health Standard (CFR 29,1910.1001) contains the following exposure limits: "The 8-hour time-weighted average airborne concentrations of asbestos fibers to which any employee may be exposed shall not exceed 2 fibers, longer than 5 micrometers, per cubic centimeter of air, as determined by the membrane filter method at 400-450 X magnification (4 millimeter objective) phase contrast illumination. No employee shall be exposed at any time to airborne concentrations of asbestos fibers in excess of 10 fibers, longer than 5 micrometers, per cubic centimeter of air, as determined by the method just noted.''
EFFECTS OF EXPOSURE: CAUTION: Breathing asbostos may cause serious bodily harm.
EMERGENCY AND FIRST AID PROCEDURES: No acute toxicity. Use respirator if airborne asbestos fiber concentration exceeds OSHA limits.
VI. SPILL OR LEAK PROCEDURES
STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED: Avoid inhalation of dust. Remove spilled material by vacuum cleaner or by water wash.
WASTE DISPOSAL:
Bags and waste and scrap materials should be disposed of in a manner which will avoid airborne concentrations of asbestos, such as the use of dust-tight trash bags or containars. Ensure that disposal complies with all applicable federal, state or local regulations.
Union Carbide Corporation assumes no responsibility and makes no warranty, expressed or implied, repre sentation, promise, or statement as to completeness, accuracy, or currency of any data provided.
UCASB00650116
VII. SPECIAL PROTECTION INFORMATION
VENTILATION:
Local exhaust for each operation is preferable. {See American National Standards Institute booklet, Z9.2 -- 1971.) General area exhaust Is acceptable. No special considerations.
PROTECTIVE GLOVES: None
EYE PROTECTION: None
RESPIRATORY PROTECTION >
The current Occupational Safety and Health Standard CFR 29, 1910.1001 contains the following require ments for respiratory protection.

(1) Allowed only during the time required for installation of engineering controls, when engineering controls are not technically feasible or adequate, and in emergencies. Current OSHA standards require that no em ployee shall be assigned to tasks requiring the use of respirators If, based upon his most recent examina tion an examining physician determines that the employee will be unable to function normally wearing a respirator, or that the safety or health of the employee or other employees will be impaired by the use of a respirator.
(2) Fibers per milliliter greater than 5 microns in length, as determined by the membrane filter method at 400-450X magnification {4 millimeter objective) phase contrast illumination.
(3) 8-Hour time-weighted average. (4) Only masks certified by NIOSH as acceptable for the exposures encountered may be usad.
OTHER PROTECTIVE EQUIPMENT: If the ceiling concentration limit is exceeded, clothing providing whole body covering shall be supplied and its use required.
VIII. SPECIAL PRECAUTIONS
Every place of employment where asbestos fibers are released must be monitored to determine exposure levels. If the permissible time-weighted average and ceiling concentration limits are not exceeded, no special pre cautions are required except:
a) Bag damage and dusting should be minimized and dust inhalation avoided. b) A comprehensive medical examination is required for any employee exposed to airborne fibers within
30 days of first such employment, annually thereafter and on termination of employment.
c) Personal work clothing can become contaminated with asbestos and may constitute an exposure hazard. Such clothing should be handled and laundered in a manner to avoid airborne concentrations of asbestos.
d) Substantial medical evidence indicates that smoking will increase the risk from asbestos exposure. Those working with asbestos should not smoke.
Where exposure limits may be exceeded, reference should be made to the regulation CFR 29,1910.1001 for details on caution signs, monitoring, change rooms, protective clothing laundering and record keeping.

Standard for Exposure to Asbestos
Dust
On December 7. 1971, an emergencytemporary standard concerning exposure to asbestos libers was published in the Federal Register (36 F.R. 23207). In ac cordance with section 6(c) (3) of the Williams-Steiger Occuptalonal Safety and. Health Act of 1970, a notice of proposed rulemaking regarding a permanent standard for exposure to asbestos libers was published In the Federal Register on January 12, 1972 (37 F.R. 466). The no tice invited interested persons to submit botii orally and in writing, data, views, and arguments concerning the proposal.
On or about January 24, 1972, the Ad visory Committee on Asbestos Dust was established and requested to make writ ten recommendations with regard to the proposed standard on asbestos. On or about February 1, 1972, the Department of Health, Education, and Welfare trans mitted to the Secretary of Labor a cri teria document containing Recommenda
