October 25, 1976 To* J ? Wolf, Plant Manager Goodyear - North Chicago During my recent visit to the North Chicago Plant, Monitoring was performad to evaluate aiaiospheric concentrations of lead and vinyl chloride. Personnel monitors were placed on tvo billet--room operators to determine airborne lead exposure of these Individuals. Monitoring was performed tilth Eondix C-115 Permissible Air Sampling Pumps and Mllllpore 0.45 mloron filters,, Sampling was conducted at a rate of 2 1pm and the system was calibrated before and after sampling. Vinyl chloride area monitoring was performed in the Banbury Storage Ires using si pin Pumps and charcoal tubes. This system vas also calibrated before and after sampling. Pertinent data eM results of the monitoring are shown in the following table. ATMOSPHERIC CONCENTRATIONS SAMPLE SAMPLE SAMPLE PARAMETERS ,, ATMOSPHERIC iHM3SRIDENTIFICATIONTIME. VOLUME. CCJTAMDIANT.

Vinyl chloride concentrations ware also lass than the "action level'* of 0,5 ppn. Considerable effort is being directed by Goodyear to the improvement of occupational health and safety programs throughout the Company* An important part of this effort is embodied in the Chemical Hazard and Toxicity Systam \GHAT)<. Tine was spent with Mr LaBrecque reviewing aspects of the CHAT system, applicable to North Chicago, and the system was discussed briefly with you. Basically, CHAT comprises a listing of chemical materials used by a particular Goodyear Plant, Many of tfcs materials are now covered by OSHA Standards (2905111910* Subpart Z - Toxic and Hazardous Substancea) limiting atmospheric concentrations of the msterials, as contaminants, in wrlc room air. Some of these materials, on the North Chicago list, arei 60036708 - 3- PARTICULATES Lead Magnesium Oxide Zlno Oxide Titanium Dioxide Zinc Stearate Calcium Carbonate Mica Kaolin Cadmium Carbon Black Amorphous Silica Diphanylamina Resorcinol Calcium Oxide Chromates p-Phanylenediamine Thiram OH Mist Sodium Hydroxide Antimony Trioxide Phenol Bis Phenol A (DGE) VAPORS Vinyl Chloride (From PVC) Odine (benzene content) Methyl Ethyl Ketone Acetone Toluene Hexane Ethanol Formaldehyde Dichlorodi fluorcnethane Propane Fhthallo Anhydride Dibutyl Phthalate Various cements (solvents) These materials, of course, present various degrees of hazard, ranging from "nuisance particulates", with a permissible atmospheric concentration of 15mg/m3 (calcium carbonate, kaolin, titanium dioxide, zinc stearate), to highly hazardous materials such as lead, with a threshold limit value (TLV) f 0,2mg/m3, and vinyl chloride with a TLV of Ippo. The actual risk of employee exposure to materials must be evaluated at the Plant under work conditions and to substantiate these evaluations monitoring data must be relied on in nearly every case. Monitoring frequency, in turn, is baaed on the hazard of th material nnd the risk of exposure in handling. Routine monitoring for lead and vinyl chloride must be continued at the N rth Chicago Plant on a seal--annual basis. Monitoring should be performed by Plant personnel and the monitoring samples forwarded to Corporate Industrial Hygiene, in Akron, for analysis. Results of this program will be incorporated into th CBAT system for reference. Personnel monitoring must be conducted to evaluate employee's lead exposure and each employee, with potential lead exposure, should be monitored, at least annually. Area monitoring for vinyl chloride should be conducted In FTC resin storage areas. Personnel monitoring for vinyl chloride phmiid be performed at operations where PVC resin is handled* Four documents that should be consulted in relation to the lead monitoring program ares (1) NIOSH Criteria Document, Occupational Exposure to Inorganic Lead (HSM 73-11010), (2) OSHA Proposed Standard, Occupational Exposure to Lead (F.R. 10-3-75, p. 45934), (3) OSHA Program Directive #200-45, Lead and Its Inorganic Compovuids, (4) OSHA Program Directive #200-47, Industrial Hygiene Field Cporations Manual, Chapter V (OSHA Standardized Method for Sampling Total Duet. Metal Fume and Liquid Aerosols). . 0036709 4 Copie8 of these documents ware left with Mr LaBreoqu*. In addition to the air monitoring program for lead, proposed here, biologic monitoring of personnel oast continue. To carry on an adequate air monitoring program, the Plant most maintain a basic inventory of industrial hygiene equipment. It is recommended that the following equipment be made available. 1.

DUPIC, a Neoprene ' latex used at the Sun Prairie Plant may contain residual amounts of chloroprene. There are several Neoprene items listed on the North Chicago CHAT list that should be investigated for the presence of chloroprene monomer but two items specifically require attention. These ere GRXMIC and SCIATIC. These codes are designated as chloroprene. 60036710 Wi'W m I ii l-WWW Usage and handling of all these materials must be relieved and monitoring performed to determine if any airborne ehloroprene monooer is present in work areas. The current OSHA TLV for ehloroprene is 25ppau Atmospheric concentration can be determined using a Drager Multi-Gas Detector with ehloroprene detector tubes No. 6718901. This equipment ia available from National Mine Service Company, 3000 Sappers Building, Pittsburgh* Pennsylvania 15219. Cost is approximately $125o I am enclosing a copy of the du Font bulletin an Toxicity and Safe Handling of Neoprene Latexes for your information. * The development of the CHAT system is essential to the successful operation of a comprehensive health and safety program throughout Goodyear. North Chicago is one of four Plants in which we ere concentrating our efforts for initial implementation of the system. We are anxious to cooperate with you in any way possible to assure that the system is workable and of benefit to all of us. Please contact us if we can be of help.
