.. D. R. Bryant 701-210 INDUSTRIAL HYGIENE MEMORANDUM To: SID Supervisors (938) R&D Supervisors Services Supervisors Mr* H. L. Robinson .. January 24, 1972 - From: Fred W? 11 lams . Increasing concern about asbestos has resulted m the Issuance of an emergency standard that reduces the concentration of airborne asbestos dust to which personnel may be exposed without approved respiratory protection. This standard became effective December 7, 1971, as reported in the Federal Register, Chapter XVII, Part 1910 - Occupational Safety and Health Standards. Section 1910,93a Asbestos dust states: (a) The 8-hour time-weighted average airborne concentration of asbestos dust to which employees are exposed shall not exceed 5 fibers per milliliter greater than 5 microns in length, as deter mined by the membrance filter method at 400-450 X magnification (4 millimeter objective) phase contrast illumination . Concentra tions above 5 fibers per milliliter but, not to exceed 10 fibers per milliliter, may be permitted up to a total of 15 minutes in an hour for up to 5 hours in an 8-hour day, (b) Engineering methods, such as but not limited to, enclosure, vacuum sweeping, and local exhaust ventilation, shall be used to meet the exposure limits prescribed in paragraph (a) of this section. Where such engineering methods are not feasible, or do not other wise reduce the concentrations below those prescribed In paragraph (a) of this section, respiratory protective devices shall be provided and used in accordance with paragraph (c) of the Federal Register. (d) (2) All hand - or power-operated tools which produce asbestos dust such as, but not limited to, saws, scorers, abrasive wheels, and drills shall be provided with local exhaust ventilation and dust collectors in accordance with the American National Standard Fundamentals Governing the Design and Operation of Local Exhaust Systems; ANSI Z9.2 - 1971. ` (d) (3) Employees exposed to the spraying of asbestos or the demolition of pipes, structures, or equipment covered or insulated with asbestos shall be provided with respiratory protective devices in accordance with paragraph (c) (4) of the Federal Register, UCC 011895 -2 - (e) Asbestos cement, mortar, coatings, grout, and plaster shall be mixed in closed bags or other containers, (0 Asbestos waste and scrap shall be collected and disposed of In sealed bags or other containers, (g) All cleanup of asbestos dust and blowing shall be performed by vacuum cleaners. No dry sweeping shall be performed. in order to protect individuals working with asbestos and to assure compliance with the Occupational Safety and Health Act, the following Is recommended; 1. Notify the industrial hygienist when work with asbestos is to be performed that can create a dust, eg; sawing, grinding, blending, demolition, etc, . (a) Air samples may be collected to evaluate potential personnel exposures to asbestos. (b) An evaluation will be made on the extent and type of personnel protection that will be needed. (c) Waste disposal arrangements can be made. (d) Record of personnel working with asbestos can be maintained. 2. When possible, substitute an insulation containing no asbestos. F.Williams/ebc \% Indw trial Hygienist UCC 011896 D. R. Bryant 770-446' TECHNICAL CENTER INDUSTRIAL HYGIENE & POLLUTION ABATEMENT "INFOGRAM" ^ A strict regulation has been established by OSHA for asbestos that requires industrial hygiene and medical surveillance of exposed personnel Operations that may produce airborne asbestos must be evaluated to determine necessary protective equipment, Asbestos debris from demolition should be placed in plastic bags for handling and burial , The industrial hygienist, phone 5129, should be informed when work involving asbestos is planned. A proposed standard has been submitted by OSHA for carbon monoxide. In this proposal, the Threshold Limit Value will be reduced from 50 ppm to 35 and no worker shall be exposed at any time to CO in excess of 200 ppm. There are also recommended monitoring, protection and medical procedures. Please notify the Industrial hygienist about uses of CO in the Technical Center. ' A Petition for Emergency Temporary Standard has been filed with OSHA by the Health Research Group and OCAW International Union for fen Carcinogens; 2-acetylaminofiuorene, 4-aminodsphenvl, benzidine and its salts, 4-dimethylaminoazobenzene, beta-na phthyiarriine, 4-nitrophenyi, N-nitrosodimethylamine, betaprop! lactone, 3,3'-dich!orobenzidine and bis(chioromethyl) ether. Zero tolerance is proposed. Some type of standard, either separately or collectively, is expected in the future for these materials, . R&D's new incinerator for burning miscellaneous chemicals and foam is scheduled for start-up soon . Acceptance tests are scheduled to begin April 4, 1973. Work is progressing on the flyash pond's odor problem. Personnel from the South Charleston Plant, Engineering Department and R&D Department, and consultants, have been working to resolve this problem . Every effort should be made to keep chemicals out of the storm sewers. The newly Installed system that conveys storm sewer drainage to the South Charleston Waste Treatment Plant cannot be used until the accelerated pumping of water from the Holtz pond is completed. F .

Kuryla ** : February 1, 1979 UCC 011902 S R Bryant 770-444 MEMORANDUM Technical Center E/D Management has asked that a list of known and suspected carcinogenic compounds be published. The attached Table includes many compounds or types of substances that are generally considered as proven c&rcinogenics ininan;' have induced cancer in animals under appropriate experimental conditions, or are regulated by specific ^Occupational Safety and Health Standards. The chemicals shown do not include all substances that may cause cancer in man or animals. For instance, in 1975 NIOSH published a list of 1,500 chemical agents as ''suspected carcinogens." Compounds were included which . caused both benign and malignant tumors regardless of ex- . perimental conditions, dose, or practical significance for industrial exposure. The American Conference of Governmental Industrial Hygienists (ACGIK) does not currently consider a substance an occupational carcinogen of any practical significance which; 1) Reacts by the respiratory route, at or above 1,000 mg/m3 for the mouse or 2,000 mg/m3 for the rat. . 2) Reacts by the dermal route, at or above 1,500 mg/kg for the mouse or 3,000 mg/kg for the rat. 3) Reacts by the gastrointestinal route at or above 500 mg/kg/day for a lifetime; equivalent to about 100 g. total dose for the rat and 10 g. total dose for the mouse. . These dosage limitations exclude such substances as dioxane and trichloroethylene from consideration as carcinogens. The National Cancer Institutefs list of known human carcinogens has been included for interest even though there is no direct interest by R/D personnel in many of the substances. As new information is published, the list of carcin ogens will be revised.

C. Pbwell, Jr. memorandum to E. L. Adkins of Institute and a June 3, 1981, R. W. Cope letter to Component Health Managers and HS & EA Industrial Hygienists have described an insulation potential health risk. In response to these communications several of you have asked,.Are substitute materials (not asbestos) available where appropriate? . . Some background, out answer to the question, and proposed action is as follows. ' 1. The involved insulation. Insulation Specification 4 (copy attached), manu factured by Goodtemp Corporation and Celotex Corporation, is selected for ethylene oxide service because it gives a combination of the safest (i. e. highest) autoignition temperature to a laboratory simulated piping leak of ethylene oxide and excellent fire resistivity. The specification notes inhalation of perlite dust may cause irritations- 2. The complaints at Institute are the first to reach our attention during the past 3-4 years. The insulation vendors state no prior reports of health concerns. No other Locations have indicated excessive irritations. 3. Depending on ambient conditions, handling, and the amount of fitting required for the job, any insulation has the potential to create nuisance dust and irritations in - some people. Respiratory protection in addition to good r industrial hygiene practices can best be used where irritations seem to be isolated instances. UCC 011906 to. I, P, Blackwood, et. al. -2- . -June 26, 1981 4. Some Locations are probably using the specifications beyond the specific need in ethylene oxide service. If this is the case, an alternate specification might be used on other than ethylene oxide fluids. 5. Based on the desired safety performance of Insulation Specification 4 in ethylene oxide fluid service, and the apparent infrequent complaints noted in the communications, we recommend continued use of Specification 4 with respiratory protection used as needed by individuals. Numerous autoignition tests have been run in the Safety Research Laboratory and it is clearly- demonstrated that a substitute insulation is not readily available. 6. If your Location receives complaints similar to those described in the March 17 and June 3 communications, please pass them to the Central Engineering Department Insulation Technologist, Ernie Powell, Ext. 4419, plus other interested Division Safety/Health Managers. There is concern for the health of our employees and if additional complaints are received, it may be desirable to trade an increment of safety on the autoignition data, for improved insulation health characteristics. However, any insulation will give some degree of dusting. If you have comment relative to the above six items, please let us know. Me will request the subject be an agenda item at the next S/H Managers meeting. DTMiabg --------------- :----------------D. T.

DURBIN H. WAY, SFPE, and CARLOS J, HILADG Union Carbide Corporation Thermal insulation systems used to conserve heat and refrigeration in industrial plants should be evaluated in the same manner as construction materials insofar as fire performance is concerned. The authors report a wide range of behavior for several insulation systems examined in large-scale fixe testa. THERMAL insulation systems play an important part in the efficient operation of industrial plants because of the appreciable value of energy employed in heating and refrigeration. Because their use is wid&spread in manufacturing facilities, they tend to be among the first ma terials subjected to flame impingement in an accidental fire. Their per formance under fire conditions, therefore, is of significant concern from the viewpoints of fire hazard, fire protection, and fire damage. A LOOK AT THERMAL INSULATION SYSTEMS Thermal insulation systems consist of three components: the thermal insulation material, which has the function of effectively reducing heat transfer; the protective material, which has the function of preventing re duction in the efficiency of the thermal insulation by the environment and by mechanical abuse; and the securement material, which has the function of keeping the entire system in place. At the very least, a thermal insulation system should present no sig nificant fire hazard: that is, it should not contribute significantly either as foe] for the fire or as a means of propagating the fire. It would be more desirable if it provided some measure of protection for the insulated pipes or vessels, preferably at least one hour before pipe or vessel wall temper atures reach a critical level. Ideally, it should survive the fire undamaged by either direct Same impingement or the impact of qofv -.hiBg water. A thermal insulation system is judged as presenting ,pre hazard if it either increases the severity of the fire in its existing location, or propagates the fire to adjacent areas. Fire hazard can result from fuel contribution by a combustible thermal insulation material, from flame spread on the protective material, or from severe failure of the securement material.

Walker Insulation Standards Team STATUS OF FIRE TEST FOR ASBESTOS-FREE IKSUXA1101 Stimulated by standards promulgated by the Oecupational Safety and Health Administration, the major manufacturers of calcium silicate insulation have introduced new products which contain no asbestos. As these new products become readily available, the old asbestos - containing materials will be phased out. The new asbestos-free products have satisfactory thermal and chemical properties; however, their characteristics when exposed to fire are unknown. For this reason the Insulation Standards Team has requested the Fire Research Laboratory to run a new series of fire tests on the new asbestos-free calcium silicate material. The testing requirements have been formulated in collaboration with the Insulation Standards Seam, Engineering Fire Rroihotlon Group and-the Fire Research Laboratory. f ' The test procedure used in the past included the use of a L'xf/" pan in which gasoline was burned as the fire source. Burning gasoline produces clouds of black smoke for a maximum duration of one hour. Present day air quality standards will not allow this amount of pollution under normal conditions. A variance can be obtained to do this testing with gasoline at our Blue Creek location; however, due to the remote location, this would necessitate a very Inefficient use of sen and materials. .As an alternate the Fire Research Lab is presently developing a new test procedure that utilises a nos-smoking fuel. Following is a general time table being followed to complete these tests: 1, Him preliminary tests to determine which non-smoking fuel most closely approximates gasoline. Hexane fuel was selected. Jan, 15 thru Feb. 2 {done) UCC 011915 -2- 2. Bun Initial hexane fire tests on old asbestos - containing Insulation to obtain control standards end to confirm correlation of hexane with gasoline when plotting ASTM Tin-Temperature Curve * Feb, 9 thru Feb, 16 {in progress) 3, Run outside fire feats on three new asbestos-free calcium silicate insulations to determine their . relative fire-resistive properties, Feb. 20 thru Mar, 1 4, Bun additional fire tests on new asbestos-free calcium silicate insulations for all combinations of thicknesses and weather barriers, Mar. 1 thru Apr, 1 5. Run fire tests on other new products such as Ceramic Poem, mineral wool pipe covering and asphaltic-based mastics. Remainder of 1973 as needed Several Gulf Coast Plants have bean using some of the new asbestos- free calcium silicates with success without Mowing their fire resistive properties. In addition, several projects are presently being designed for which insulation material contracts will need to be negotiated by early March, 1973. `Therefore, our.Immediate seed is the results from Step 3 of the above schedule. After the results of Step h are obtained, sufficient data will be available to select the best materials for inclusion in a permanent Group I Insulation Standard, Although of lesser urgency, the results from Step 5 will be required for several promising materials before Group I approval can be given.
