Naatx Toledo 11 P* Scheuerl* - Berlin On January 26 and 27, 1971, a aeries of samples ware taken inside the plant by the writer* These were to act as a check on engineering work already dene, and to aid in further planning, as requested by the plant* They will be compared, where possible, with the results of the previous survey *vaui by Clayton & Associates In June of 1970. A copy of the raaulta of the . January, 1971 study la attached* Since the June 1970 eurvey, a number of engineering and process charges have been made In the finishing end of the plant, while essentially nothing has been done on the #1 and #2 pouring lines. In addition, the filter press operation has been broughe as least partially on line since the June 1970 etudy. These samples were checked for two things* The first was the dust concentration, which Is reported In mliligcaas/cubic eater (tag/M*), and would Include fibrous Material, aa well aa particulate dust* The sample was also checked for asbestos fibers, with the counts reported in flbers/ailllllter of lengths greater than 5 aicrona, greater than 10 micrccs, and total. The health threshold of 5 flbers/nl greater than 5 micron* Is based on the prevention of asbestosls, but no actual lluit has been set for the prevention of lung cancer* There is tome United evidence that shorter fibers cay be a factor, and this should be kept in mind* Also, no actual exposure rate and dose response has been determined for this feal health hazard* . . . ,t ` ` .. ... .. . The finishing and of the plant, while the equipment, and especially the FI saw is operating correctly, as was the case during these sampling periods, 'appears to have level* which ere satisfactory with one exeeptloa* The F-l unloader (in-feeder) still is getting excessive exposures, but corrective work is to be soon completed, with a conveyor extension and e local exhaust rework* The filter press operation appears veil controlled, although under process -- conditions during the sampling periods, excesslva amounts of water are being . used, which may have been aiding in control* However, the batch mixer for this area require* better process control ventilation, as Veil aa hood redesign for more efficient operation* Jon L. Konzen, KD Toledo 11 RKRLIN PLANT Pafe 2 February 17, 1971 \ The operations of the #1 and #2 lines are a definite source cS reel health exposure to all who work on thee. Ventilation control# are -.badly needed, and the exposures are serious enough to require- personal 'respiratory protection on an interia basis until these controls can be - Installed. These pouring lines are ooe of the few areas of this plant 'where comparable results between the June 1970 study and the January 1971 study can be noted* In both studies, the results are almost identical and show levels well above the recocsended threshold values* These results are listed below for comparison purposest Operations Juna 1970 Study ng/H3 Fibera/^l January 1971 Study ng/n3 Fibera/al #1 Lise Service 7.A 34.2 1.59 15.1 34.4 17.1 fl Line Pourer #2 Line Stripper 8.9 24.2 39.1 2.18 14.1 11.5 2.0 21.1 0.31 8,62 12 Line Pouter 14.2 1.54 19.2 1.66 Recommendations 1* The stroog need for local control of asbestos and dust on the pouring lines has bees reconfirmed* 2* Until such positive engineering controls are installed, a personal protection program for all pouring line employee* is required, as veil as batch nix operators* 3* The filter press batch nixing ventilation system needs redesign for better control* If there are any questions or coaasote, please do not hesitate to contact ee* 4* K.
