INTRODUCTION
The purpose of this protocol is to establish a two-year Occupational Health Program for EDC/NPA, A-7001. The program provides a basic strategy for industrial hygiene monitoring, health hazards training and medical surveillance for employees assigned to the units.
A review of the personnel roster and chemical and physical agent inventories will be conducted annually. Revisions to the protocol will be made as necessary and the complete protocol document will be reissued on a two-year basis following the consolidated audit.
The results of industrial hygiene monitoring will be reported to employees as soon as possible after completion. A formal report will. be issued when all monitoring is completed.
Medical surveillance will be, reported to each participating employee. Using individual medical information and pertinent industrial hygiene data, a group analysis of the entire plant population will also be conducted and reported to supervision. If any special health concerns are identified, the physician, in cooperation with supervision and industrial hygiene will jointly review the data and communicate findings to affected plant personnel.
REVIEW OF PAST MONITORING DATA
Personal monitoring of chemical exposures has been evaluated at EDC/NPA since 1973. The most recent data was collected in 1988 and 1989. Routine personal exposures to ethylene dichloride; 1,1,1,2 tetrachloroethane; 1,1,2,2-tetrachloroethane; 1,1,2-trichioroethane; vinyl chloride and vinylidene chloride were the stresses of major concern; however, several other chlorinated organics were evaluated as well. All average 8-hr TWA exposures were less than the exposure guidelines with the exception of ethylene dichloride. A summary of the 1988-89 monitoring results are given in Tables I and II.
In 1988, the Control C Operator 8-hr TWA exposure of 3.6 ppm to ethylene dichloride exceeded the OSHA proposed Permissible Exposure Limit (PEL) of 1.0 ppm. The Control C Operator short-term exposure of 25 ppm to ethylene dichloride exceeded the OSHA proposed Short-Term Exposure Limit (STEL) of 2.0 ppm. Installation of a closed-loop sampling system was recommended to reduce employee exposure potential. Respiratory protection was made mandatory during the interim.
In 1989, the Control C Operator 8-hr TWA and short-term exposures to ethylene dichloride exceeded the OSHA PEL and STEL of 1.0 ppm and 2.0 ppm, respectively with average exposures of 1.3 ppm and 5 ppm, respectively. The closed-loop sampling systems had not been installed yet to control the exposures. Respiratory protection was worn.

REVIEW OF PAST MONITORING DATA (CONT'D)
Comprehensive noise surveys were carried out in 1982 and 1988. All 8-hour TWA noise exposures were well below 50% of the OSHA allowable (See Table III below). However, 1988 area data identified many areas and/or equipment that exceeded the IHG of 90 dBA as a Ceiling. As a result, the production"area of A-7001 has been designated as a hearing protection area until engineering controls can reduce the noise levels below 90 dBA. Sound muffling devices are currently being investigated to reduce bleed valve noise.

EVALUATION CRITERIA
Industrial hygiene monitoring is performed to determine potential exposure levels both as a daily time-weighted average (TWA) and peak or short-term exposure. The results of monitoring are compared with the recommended exposure guidelines given in Tables IV-A and IV-B. These values are basedvon toxicology data and industrial experience.
Threshold Limit Values (TLVs) are established by the American Conference of Governmental Industrial Hygienists (ACGIH), Industrial Hygiene Guides (IHGs) are established by Dow, and Permissible Exposure Limits (PELs) are established by the Occupational Safety and Health Administration (OSHA). They represent airborne concentrations of substances to which nearly all employees may be repeatedly exposed throughout a working lifetime without adverse effect.
OSHA recently adopted most of the guidelines set by the ACGIH. Employers are required to be in compliance with the new limits by September 1, 1989, using any combination of engineering controls, work practices and personal protective equipment. Whenever feasible, engineering controls must be in place by December 31, 1992.
A Short-Term Exposure Limit (STEL) is defined as a 15-minute timeweighted average exposure which should not be exceeded at any time during a work day even if the 8-hour time-weighted average is below the TLV.
The Skin (S) notation refers to the potential contribution to the overall exposure by absorption through the skin including mucous membranes and eyes, either by airborne or more particularly, by direct skin contact with the substance. Repeated or prolonged contact with most organic liquids will result in drying of the skin which enhances a chemical's skin absorption properties. Skin contact should be avoided
A Ceiling (C) is defined as a concentration that should not be exceeded at any time during a work day even if the 8-hour timeweighted average is below the TLV.
A Dow Biological Limit Guide (BLG) represents the amount of contaminant in a worker's exhaled air, urine, blood or other appropriate biological specimen that may not be exceeded. The contaminant can be the contaminant itself, a metabolite or a biochemical change brought on by the introduction of the contaminant into the body.

The Dow Industrial Hygiene Guide is a 90 dBA Ceiling. It requires that employees wear hearing protection when exposed to continuous, intermittent or impact/impulse noise exceeding 90 dBA. Whenever exposures exceed the OSHA PEL, feasible engineering and administrative controls are required to reduce exposures. The OSHA Action Level of 85 dBA as an 8-hr TWA requires a Hearing Conservation Program. Annual audiometric testing, education and training, and other requirements are included in the program. In addition, Texas Operations Safety Standard 0-46 requires the use of hearing protection by all employees whenever the noise dose exceeds 85 dBA as an 8-hr TWA. Further details on the program are located in the "Texas Operations Hearing Conservation Program Guidelines" (1/88)

APPENDIX A SURVEILLANCE PROGRAM
1. RATIONALE
In 1990, wipe testing will be conducted for hexachlorobenzene to determine if this compound is present in the EDC/NPA process areas and if it has been tracked into the nearby buidlings, maintenance shops, etc. Also, short-term monitoring will be conducted for ethyl chloride; ethylene dichloride; 1,1,2-trichloroethane; 1.1.1.2-tetrachloroethane; 1,1,2,2-tetrachloroethane; vinyl chloride and vinylidene chloride during line and vessel opening activities.
In 1991, personal and area noise monitoring will be conducted as required by Safety Standard 0-46 which requires a noise survey every three years. The last noise survey was in 1988. The survey will also ensure the effectiveness of the noise controls.
In 1991 (if the closed-loop sampling systems are installed by this date), the following chemicals will be monitored for eight-hour TWA and short-term exposures: ethyl chloride; ethylene dichloride; 1.1.2-trichloroethane; 1,1,1,2-tetrachloroethane; 1,1,2,2tetrachloroethane; vinyl chloride and vinylidene chloride. The monitoring will be done to ensure the effectiveness of the closedloop sampling systems.

3. METHODOLOGY
Eight-hour TWA samples of ethyl chloride; ethylene dichloride; 1,1,1,2-tetrachlorethane; 1,1,2,2-tetrachloroethane; 1,1,2 trichloroethane and vinyl chloride will be collected on 1 gram charcoal tubes using calibrated personal sampler pumps (approx. 50 cc/minute) to draw known volumes of air through the tubes. The charcoal is desorbed with carbon disulfide and analyzed on a FID gas chromatograph. The front and back sections of the charcoal tubes will be analyzed to detect any breakthrough. Short-term samples of these chemicals will be collected by the same method. However, the personal sampler pumps will be calibrated to an approximate flow rate of 200 cc/minute The samples will be analyzed according to Dow Method HEH-IHM-83-25A
Wipe testing of surfaces for hexachlorobenzene will be performed using 35 mm Whatman #1 filters. A disposable polyethylene glove will be worn and discarded for each sample. Flat surfaces such as table tops and floors will be wiped using a template with an exposed area of 100 square centimeters. Other surfaces such as door handles, phones and process control knobs, where the template cannot be used, will be completely wiped. After wiping, the filter is folded and placed in a 3 dram vial. Analysis will be performed by extracting with 10 ml of n-hexane and determining the total micrograms present using electron gas chromatography. Proper procedures for a wipe testing program are outlined in Industrial Hygiene Reference Procedure IHP-403.
Personnel monitoring for noise will be conducted using Quest Model M-7B noise dosimeters which will be calibrated before and after each use with a Quest Model CA-32 sound calibrator. The area noise survey will be conducted using a Quest Model 215 sound level meter which will be calibrated before and after each use with a Quest Model CA-32 sound calibrator.
4. QUALITY CONTROL
Routine quality control procedures shall be an integral part of the sampling and analysis procedures and functions. These shall include:
a. Routinely introduced sampling of blanks and spikes (known content) along with the other samples for analyses.
b. Routine checking, calibrating, and maintaining in good working order all equipment and instruments. Air sampling pumps will be calibrated both before and after use.
c. Routine checking of procedures and results.

APPENDIX B INDUSTRIAL HYGIENE EDUCATION PROGRAM
The Industrial Hygiene'Education Program is designed to inform workers of the chemical and physical agents in the workplace which may have an adverse effect on the health of the employee. It is believed that an understanding of the hazards of the chemical and physical agents will reinforce their safe handling by the workers.
The annual health hazards training will focus on the following key physical agents:
1990:
1991:
Ethylene dichloride Hexachlorobenzene 1.1.1.2- Tetrachloroethane 1.1.2.2- Tetrachloroethane Vinyl chloride Vinylidene chloride Ferrozine
1,1-Dichloroethane Ethyl chloride Ethylene dichloride Hexachloroethane Noise Perch!oroethylene
The education program will include presentations by department supervision and/or Industrial Hygiene Services reviewing the taxi cities of the key physical agents in the block and include discussions about specific job procedures for tasks with a potential for employee exposure and the control methods in use.
Industrial Hygiene will assist EDC/NPA in developing a written personal protective equipment program during 1990. The respiratory protection program will also be reviewed and revised as necessary.
The Industrial Hygiene Manual contains information about the effects of overexposures to each chemical in the plant. It must be kept in an area that is readily accessible to all plant personnel. All personnel should be reminded of the location of the manual.
Participation in the Industrial Hygiene Education Program should be documented. The training documentation form is in the Training Guideline section of the plant Industrial Hygiene Manual. It is important to briefly describe the program's content and to obtain the signature of employees in attendance. When the annual training is complete, forward the original form(s) to Industrial Hygiene Services, B-101, for inclusion in the plant's compliance file (75-year retention).

APPENDIX C
MEDICAL SURVEILLANCE PLAN
All employees in the Ethylene Dichloride Department (EDC/NPA) are offered a Periodic Core Examination every two years. Participation in the periodic examination program is voluntary. The examination consists of a health history questionnaire, blood and urine tests, physical measurements (height, weight, and blood pressure), and breathing, hearing, and vision tests. Chest x-rays, electrocardio grams, hemoccult (blood in the stool), and glaucoma tests are offered on an age-related schedule.
The Dow Medical Surveillance Requirement (MSR) program is also voluntary and is supplemental to the Periodic Core Examination Program. MSR examinations are targeted to detect health effects attributable to specific agents or work requirements. However, except for limited instances where actual tissue levels of a substance are determined (biological monitoring), most tests are non-specific Indicators of organ function or injury. A MSR does not exist for all chemicals or physical agents. Where an MSR does exist only those job classifications with a Priority Rating of 1 or 2 must be included in the program. There are a few Medical Surveillance Requirements based on plant/department assignment or previous exposure potential. MSR tests and frequencies are different for each material. All OSHAregulated chemicals or physical agents have Dow Medical Surveillance Requirements which conform to the OSHA Standard. Individuals whose potential exposures meet or exceed the Action Level are included in the MSR program and must be offered examinations as specified in the Standard. On occasion other employees whose potential exposures are less than the Action Level may be placed on the Dow MSR. These two groups will be clearly differentiated.
Review of the current Chemical and Physical Agent Inventory reveals that no chemicals with a Dow MSR have a Priority Rating of 1 or 2. Ethylene dichloride does have a Priority Rating of 2 for the Control C Operators. However, under the Dow MSR system there is no additional testing required. Review of the 1988 Noise Survey shows that the eight-hour time-weighted average exposures to noise are all below 85 decibels on the A-scale and therefore there are no job classifications that must be included in the Hearing Conservation Program. All employees in the Ethylene Dichloride Department will continue to be offered the Periodic Core Examination.
