NF-6-80/JHP-15-80 EVALUATION OF THE INTRODUCTORY INDUSTRIAL HYGIENE COURSE The November 11-13, 1980, course preserited an overview of in dustrial hygiene. James T. Schirripa from Industrial Hygienics, Inc., and his associate, explained how to set up, implement and maintain an industrial hygiene program, with emphasis on the recognition, evalua tion and control of industrial hygiene problems. This included such areas as identification and types of occupational diseases, how hazard ous material exposure limits are determined, personnel monitoring and analytical techniques, ventilation engineering and protective equipment evaluation and use. On the last day, Mark Stenzel and Grover Vos, Celanese Chemical Company's industrial hygienists, outlined Celanese's industrial hygiene program. They described the methods and techniques used by Celanese for the recognition, evaluation and control of in dustrial hygiene problems, particularly with regard to the computer assisted Health Surveillance Program. They also made a plant-by-plant breakdown of hazardous materials exposure problems. Throughout the seminar, emphasis was placed on the importance and benefits that a good industrial hygiene program has for the company, employees and com munity. The course was educational for people with or without experience . in industrial hygiene because it provided a good overview of industrial hygiene and it also involved looking at several aspects in detail.. Industrial Hygienics' presentation was especially beneficial because ' they not only covered the problems on the whole, but they also addressed problems specific to Celanese. The Celanese Chemical Company industrial hygienist's course wrap-up was also beneficial because they detailed the scope of Celanese's industrial hygiene problems and defined Celanese's industrial hygiene program. The course was helpful because it organized the elements of industrial hygiene to make for a better understanding of the field and, in turn, better problem solving. After participating in the course, we recommend that others participate, particularly if Industrial Hygienics, Inc., personnel give their presentation. NF/JHP/klv cc: E. Munoz R. G.

TheMIRAN-801 system is a signifi cant advance in amdient air monitor ing. It provides a cost-effective means of complying with OSH A require ments for reporting the concentra tions of toxic gases in areas where your personnel are exposed. It 'educes the need for costly personnel monitors. When an alarm condition is sensed the operator is notified immediately ana workers can be alerted. Convenient, time-weighted averages show, at a glance, the average concentration of as manv as 0 toxic gases at up to 24 locations, "his information is avaiiaole in print out form oy the smft and by the month. There are three other reasons wny theMIRAN-801 system is a major advance in ambient air monitoring. They are: Up to ten toxic gases can be monitored simultaneously, unat tended, at up to 12 or 24 locations. Previously, only one toxic substance could be monitored. The system provides a convenient printed record which will substantiate /our company's compliance with OSH A limits for toxic gas concentra tions in ambient air. The printout, wnich can also be used as a manage ment guide for safety planning, records concentrations in parts per million, with each monitored location identified by number. Time of sam pling and any alarms given are also noted on this printout. The system s built-in micropro cessor makes possible the sum marization ot data for convenient analysis ana recora storage. This summary printout oitime-weignted average concentrations measured can be made for each shift, both daily and monthly. The data provided in cludes monitoring station number, average concentration for each gas under study, thenumoerof readings taken, the number of times an alarm level was exceeded, and the highest reading. The MIRAN-801 system is an accurate, dependable means for monitoring and recording ambient air quality in manufacturing areas, laos. machine shoos, paint spray booths, storage areas, quality control facil ities. cnemical processing lines, ex haust air ducts, test areas and other locations as far as 1.000 feet from the unit's central control cabinet. Microprocessor control enables multi-component monitoring. Microprocessor control makes possi ble the simultaneous sample collec- on. ^-jiti-comoonent analysis, cata .-eaucticn. and the printouts and aiarm signals necessary for monitorng up to 10 potentially toxic vapors around the clock. One significant advantage of the MIRAN-801 system resulting from full microprocessor control is its ability to be programmed to monitor any desired selection of (up to 10) in dividual gases and later to be reprogrammed to monitor a different selection of gases. Or. initially, it can monitor less than 10 gases with others added at a later date. Built to last under rugged plant operating conditions. TheMIRAN-801 system's heavy duty construction and all solid-state elec tronics on piug-in ooaras assure long service life, with ease of service and minimal downtime. Principle of operation: The operating principle of the MIRAN-801 is straightforward and uncomplicated. An ambient air sam ple is collected at one of the remote sampling points and is pumped into the sample cell of the system's single-beam infrared analyzer. The analyzer then passes an infrared 002398 o o 00 hz- I cr Q. < Hi E-1 5 CL < CO ui CD <r cc U3<LJ Uh i X CD U3J XUJ c3oc 0I0 uo.!JsJJ qq s Ulu.

The concentration of each gas umpie in parts per million is then re corded on a paper printout. The print out is your round-the-clock record of ambient air conditions throughtout your plant, labs, offices, etc. Should the concentration of any of .the gases being monitored exceed SSHA limits, an aiarm is automat- :a!lv triggered at the unit's control tabinet. Personnel alarms at eacn monitored station can befitted to the system. A summary of alarms is in cluded in the printout provided by ' the system. * 3-yscur ana momhiy summaries of time-weighted averages simpiify compliance records. A major feature of the MIRAN-801 system is data summarization, as illustrated by printout photo graphed below. As you can see. this single printout sneet contains the data you'll need to substantiate OSH A compliance for an 8 hour shift. A monthly record is also available. Data for each gas monitored is provided by sampling location and includes the number of readings, average concentration, maximum concentration and times ot day these .eveis were reacneo. and numoer of alarms. H ign concentration alarms, as well as loss of flow and system malfunc tion alarms, are also cleariy indicated on the printout. No other amoient air monitoring system provides such a concise, ac curate and comprenensive record for OSH A-compiiance verification and for management or plant safety planning. Typical applications Area monitoring * OSHA compliance testing of toxic vapors and gases ' Leak detection * Warning or chemical spills > Checking ventilation system effi ciency Use anywnere that continuous, unattended, multi-point, multicomponent monitoring is required. 426...4J4 5.6 435...479 5.2 000...356 20..46 1660...443 6.0 \6.0 3 002400 B-Hoi/n rrnr heighteh ebe 4.8 7.3 2.6 44..24 9.4 8.8 7.2 3.0 2.9 2.9 2. 7 3.1 3.2 6 62 8y2044 5535366668776914434S8088028 11146609023948869042712J767J?7940 sse I'OMCS, COC,,,SMirj " 1i..o3 46733334.....8.4..203228 2.0 121...919 2449....4864 9222....4478 111142...498 3,2 H 10 11 12 1J 14 I145 17 ia 1v16167-01.11774.11.7'I3.473.74I4.6.014.1.i51.41i131s'.`391.1i073I1-10O0..0S1:1I.149431a.43143.4I0.3I13148J31?01/90l1392lJ103o7l.;531'5i4?13r100|l409o04v:4r31ij4a444M44614"`0,J703r1"4*13441'5141*77121244I0/1410**387/;71l5431149.381X00M1-1951-/012lJ7'171330.111135f413'4?11444i0i3640;or3416*;4:|!9n01o0O3i0I0100?.o3'34.7J7*.0r70*08*0.0"<8.740.*1.71*18*191.340>163-419.351514Oi01.5./34*s//1313443941.31//C14;*3/53,33131173-/127J011387361,1113313112*321?1103130103-90/34/3433/#?133109?/7534>42>3.>0,o700*?..**0.790.o1.703.13A*.11*41.'32I.>80.3E7149i1.3.47I0?I.1.4:3..30**:9S41*-3.11341E00|*:I:105010117J3:3.17121.123.143113.73.2114I1304103.01J11090.J17163/14123!3140304341476141018125?60628484544841714171917*119t15?12602/173212*1J0120/103013233/18/10110/131/3/03122/3J93122?93803401/3103348//0*5?9/100041/2114641343112313102864310070I7717891611'482174727004478074347711412840973820138132204120413041083I*283731021510530/204/11/54422e18/418114J7/5/571/2230_3/5?30005/140838/1/031410>0_/l3o4/107344434/;1132rj00!643o02112124794''78224761A8727623571411724-2I185>2113I2154/1242593/1I4/91912/11124J2/11//5721533*3719741200332343/1304/00/220/309343442109842010022*3*4.01.3.50.4020.0.07.-81.2.9.8.4.24.0*023*.3332117.1-18847232882218J8/1818/:2121221223/2/1002X/82/28/J114181/2211119/30029/074/03O02340/384I61J2O2004421322781361187867*1.01.113.7.8*4*23.8.24.64.824.4.8628402.32.....8.*41?.4814141641112112235441|8441811/198111818|81/112//41//4124t33333/15/1533550?91502?03083/03/0/20/5/314508956444420482007 IS 1111230263456824220222 IliIOIIosSSSae; 243864 1t2Sl3i!| ,ViiRAN-3C1 System Specifications :rincioie or measurement: ProgrammaDie wavelength infrared analyzer.

SCOPE AND APPLICATION This colorimetric teat is applicable to the detection of magnesium (II) and iron (II) from asbestos in-bulk samples. These samples include sprayed on asbestos as well as ceiling tiles. The test is simple and can be readily used in the field to screen for the presence or absence of asbestos. The amount of the sample needed for the test is only about the size of a large pea. II. PRINCIPLE The te|tj is based upon the formation of glor complexes with Mg+2 and Fe released from asbestos. The Mg chrysotile is complexed with p-nitrophenylazo-a-naphthol. The Fe from crocidolite and amosite is complexed with 1, lO-phenanthroline.^A positive+|est is indicated by the formation of colored complex for Mg and/or Fe , and it indicates possible presence of asbestos. III. INTERFERENCES The test is a colorimetric spot test for Mg+2 and Fe+2 , and is not specific for- asbestos* A bulk sample may contain Mg and Fe compounds other than asbestos. Without treating the sample as in the Procedure, a few drops of color forming reagents are added directly to the sample. If either color forms, an interferring substance is present and the sample must be cleaned before the test is conducted to eliminate the interference. In this cleaning process, plaster, mineral wool, fiberglass, and soluble Mg and Fe compounds are removed before the screening test, preventing their interference. IV. SENSITIVITY, PRECISION, AND ACCURACY A sample containing more than 1Z asbestos gives a positive color reaction. A total of 198 various field samples were tested before the Acid Wash steps were added to the Iron Test procedure. Results are listed be low: Results of the screening test without the Acid Wash.

If blue color appears, wash the sample with glycerin before the test. Any sample containing plaster is also washed with glycerin. Glycerin Wash a. Place a small portion of sample, about the size of a large pea, in a plastic beaker. b. Add 5 drops of glycerin and mix well with a plastic rod or spatula. c. Rinse the plastic rod with a small amount of water into the beaker. d. Filter the sample through the filtration assembly consist ing of a syringe attached to the Swinnex filter holder loaded with a mixed cellulose ester filter and a gasket. e. Filter with a minimum of 5 washings or about 50 mL of water. f. Transfer the filter to a Teflon dish for the Magnesium test. 2. Add a drop of H^PO^ and mix well by grinding the sample with a plastic rod. 3. Add 2 drops of 10 N NaOH and mix well. 4. Add 5 drops of Mg Reagent and stir briefly. Note any color change. 5. Add 5 more drops of Mg Reagent and observe the final color. 6. A blue color indicates that chrysotile may be present. 7. Samples giving a positive test may be sent to a laboratory for confirmation. If the magnesium test is negative, the sample must be tested for Iron. B. Iron Test 1. Add few drops of Fe Reagent directly to the sample. If a red color appears, wash the sample with the acetic--sulfuric acid mixture before the test. Samples containing fiberglass or mineral wool are also washed with the acid mixture. 002407 Acid Hash 1. Place a small portion of the sample, about the size of a large pea, in a plastic beaker. 2. Add 5 drops of concentrated acetic acid. 3. Add 5 drops of concentrated sulfuric acid. 4. Mix well and ultrasonicate if available for 5 minutes. 5. Filter the sample through a polyVinyl chloride filter with a minimum of 5 washings or about 50 mL of water. 6. Transfer the filter to a Teflon dish and proceed with the Iron Test. 2. Add a drop of HF solution and mix well. 3. Add 5 drops of Fe Reagent and observe the development of red color. 4. The red color indicates that amosite or crocidolite may be present. C. Notes If both parts of the test give negative responses, there is a low probability that any asbestos is present. Once the presence of mag nesium and/or iron is indicated, further analysis, if needed, is done in the laboratory to confirm, identify the type, and quantitate the percentage of asbestos. VIII.
