This is chiefly due to the contaminant, vinyl chloride. Alternative breathing air systems should be __ investigated. jtrl' ^ 'Xtv jrzot'tr*' i /'tr `JrL tr -u'.t' y VC4719 BATON ROUGE PLANT BREATHING AIR Draft - Page 2 Method of Evaluation The efficiency of the breathing air system was evaluated by comparing the level of contaminants found at various breath ing stations with the level of contaminants found at various air compressor inlets. Professional judgment determined when the system was characterized adequately. Conclusions concerning the present breathing <air system and materials found'passing' /j ->-> ^ ^ikuj c tm id- GAsJro\rvJ through^this system were7made after comparing the contaminant levels which were found with standards. The Recommendations which are presented also take into account how certain other chemical plants deal with their breathing air. " Description of the Breathing Air System Breathing air is taken from the plant utility air system. The compressed air for the utility air system is supplied by thirteen compressors located at various spots throughout the plant. The air inlets for these compressors range from three feet above grade within the organic lead area to seven feet over grade within the hydrocarbon area. The compressor inlets are shielded by rather coarse particulate filters. Compressors for breathing air are required to have automated shut off devices which should operate when a compressor produces excessive carbon monoxide in its breath ing air. Most of the plant compressors are reported to have VC4720 Draft - Page 3 temperature sensors which will lock out its compressor if it should over heat. However, the last two times people have apparently become ill reportedly from the effects of compressor fire, the fire was reported to have occurred within a compressor location not protected by these temperature control devices. Plant Maintenance is responsible for these compressors and since May, 1974, maintenance personnel have been checking compressor outlet air quality daily for carbon monoxide and carbon dioxide levels. This is for OSHA com pliance. They are employing a detector tube technique at seven sampling points downstream of the various compressor group locations. Detector tubes for this procedure are expected to cost about $7,000.00 annually. These spot checks for carbon dioxide levels have ranged from a usual of 300 ppm up to an occasional 1,000 ppm. Carbon monoxide has ranged from a usual one ppm up to an occasional 10 ppm. It is believed the portable air compressors have produced the highest contaminant levels. The standard permits a maximum of 20 ppm carbon _ monoxide and 1,000 ppm carbon dioxide. The compressed air from all of the compressors passes to the utility air line common to the entire plant. This utility air line .is to supply breathing air systems where needed. Cons quently, inlet air at a compressor within the TEL area may at times be inspired by sandblast personnel on the other side of the plant. The breathing air tap line first passes to a knock out expansion chamber, then to a charcoal filter. The compressed air pressure leaving a charcoal filter is reduced from 100 psi to 28 psi. This air then passes to VC4721 Draft - Page 4 a distribution system which is used exclusively for breathing air. Presently there are about 20 sets of knock out pots with charcoal filters and distribution systems within the organic lead area# three within the hydrocarbon area# three within PVC. Portable type filters are used when breathing air is required within the Sodium area. Positive pressure continuous flow respirators may be connected to the distribution systems at any number of quick connect couplings located on the downstream side of the various utility air - knock out, charcoal and reducing - points. A con servative estimate of the weekly requirement for breathing air within the Baton Rouge Plant is: Hydrocarbon Area, 8,000 cubic feet per week; PVC area, 34,000 cubic feet per week; TEL area, 250,000 cubic feet per week, and for the two major sandblasting areas is 90,000 cubic feet per week.

The estimates herein for breathing air use do not in clude requirements for additional breathing stations within hydrocarbon and polyvinyl chloride areas. It is understood Plant Maintenance expects to adjust breathing air to deliver between four and five cubic feet of air per minute per outlet. They also expect to replace the charcoal filter adsorbent material for breathing air on a regular basis. It is believed the present thermal lock out devices were designed for protection of the compressor and not to avert breathing carbon monoxide as is required by OSHA. Hence the system does not meet OSHA requirements. The OSHA standard for compressed breathing air calls for Type 1 Grade D air which limits the concen tration of condensed hydrocarbons and carbon monoxide, however it does not set maxi mum limiting values for gaseous hydrocarbons or halogenated solvents. Other specifications,for example,that from the National Aeronautics and Space Administration (NASA) do limit these chemical levels and with the exception of vinyl chloride, present plant breathing air was found to be within these limits VC4729 Draft - Paqe 12 most of the time. However, it should be noted NASA also claims it purifies its compressed airAto remove all hydrocarbons, con densed or gaseous, and also desorbs and converts all carbon monoxide to carbon dioxide. Our neighbors, Exxon, reports it uses"compressed air '4 cylinders for breathing air except for sandblast and painting operations. The employees who conduct these tasks use breathing air which is supplied from a compressor located within an air- conditioned shop building. Incidentally, the writer was informed by a local distributor that a two year back order for the avail - ability of compressed air cylinders exists at this time. Dow Chemical, at Freeport, Texas, uses an Ingersoll Rand, 4-stage Robins Aviation Compressor whose inlet is on the Gulf side of their plant (four miles away from the vinyl chloride operation). Reportedly the compressor is used exclusively for breathing air. Compressor air treatment includes a mechancial filter, molecular sieve, dew point monitor, activated charcoal bed and a Hopkolite bed for conversion of carbon monoxide. Environmental data presented herein indicates vinyl chloride methyl chloride, ethyl chloride, ethylene dichloride and/or 1-1"1 trichloroethane, 1-1 dichloroethane and chloroform cycle through the utility breathing-air system from compressor inlet to breathing outlets at concentrations which are undiminished from start to finish. Due to other priority requirements, R&D analytical could not free an additional chromatograph for quan tification of other suspect materials such as vinylidene VC4730 dl u *" .reiyt? u < ' chloride, ethylene dibromide, carbon tetrachloride, vinyl acetylene or^ph<ysqerv&. However, in view of the low permissible level (1 ppm) for vinyl chloride further search for chlorinated unknowns is not justified in terms of "go" or "no go" for breath- ------------ ---Wti `i'Wav A \ ing air quality. The system permits^excessive)levels of vinyl- chloride. The reasoning for another method of evaluation goes something like this: Since there may be chance for exposure to excessive contaminant levels while working around areas which require wearing an air mask, it is thought contaminant levels for mask breathing air should be less than the threshhold limit values (TLVs) for work air. An acceptable target here has been 10% of the TLV level. For our breathing air evaluation, this approach has for its target 0.1 ppm which is 10% of the TLV for vinyl chloride. Again, the low OSHA vinyl chloride requirement blocks acceptability of plant breathing air quality. This does not mean the removal of vinyl chloride from the breathing air would guarantee acceptability. 'It should also be brought out. the data suggests anyone, including those working within the 0^ V* A" organic lead area, using the breathing air should be included in the action level program for vinyl chloride. Their exposure OLevel will exceed 0.5 ppm. Finally, it was found the vinylchloride contaminant level was reduced significantly by the \ triple charcoal filter system within "C" Building. However it is not expected this would be a permanent solution. Finally, in formal data was receive which suggested vinyl chloride breathing air levels of two or three parts per million within the breathing tb.i, ,n- </. itO ,c?T,.vy , uj ' `V/ 4 /** }/eXr ^ tf > V lh- 4'?^ C( -J. j Cm yui'cL, > fo . *+ '*.**<* ,//4 p * J+ ' -4 t/' i'X 'l fC TP/tO A Drart - Page 14 air system in the hydrocarbon area. This probably represents some averaging over longer collection periods. Most of the meaningful hydrocarbon samples taken for thisL^valuation were collected over a three to four hour period. Thus hydrocarbon peak levels are not identified. Most certainly, peaks exceed the 5 ppm ceiling limit value. Conclusion The concentration levels of vinyl chloride found within the plant breathing air system make this air'unacceptable for protected breathing. I believe continuing this evaluation will only? ^ incriminate breathing air quality to a greater extent. Recommendations1 2 3 4 ! /r1 1. Ideally, Consideration should be given fox maa^uaSX' to A' dev61op'\ process to polymerize or somehow remove vinyl chloride from the breathing air system. 2. Consideration should be given to identify an area within or over the plant which is relatively free of vinyl chloride and other chlorinated contaminents. 3. Consideration should be given to installing a breathing air "oilless" compressor or compressors together with air purifying pretreatment systems. Breathing air from this equipment could be fed into the ei*isLing knock oufa/ ultaiLual, pressure reducing- l> air distribution network. "V U^T' u'"*l **^f^+~**\'s** 4. As soon as possible the engine exhaust outlets from the portable air compressors should be ducted to grade level to minimize carbon monoxide contamination of intake air as now occurs. If this is objectional because of excessive engine back pressure. VC4732 Draft - Page 15 the compressor air intake opening should be raised at least three feet through an enlarged stack.
