<br />GIENEAND MEDICAL SURVEILLANCE GUIDE-
<br />LINES
<br />I. INDUSTRIALHYGIENEGUIDELINES
<br />A. Sampling (Benzene-Soluble Fraction
<br />Total Particulate Matter).
<br />Samples collected should be full shift (at
<br />least 7-hour) samples. Sampling should be
<br />done using a personal sampling pump with
<br />pulsation damper at a flow rate of 2 liters
<br />per minute. Samples should be collected on
<br />0.8 micrometer pore size silver membrane fil-
<br />ters (37 mm diameter) preceded by Gelman
<br />glass fiber type A-E filters encased in three-
<br />piece plastic (polystyrene) field monitor cas-
<br />settes. The cassette face cap should be on
<br />and the plug removed. The rotameter should
<br />be checked every hour to ensure that proper
<br />flow rates are maintained.
<br />A minimum of three full-shift samples
<br />should be collected for each job classifica-
<br />tion on each battery, at least one from each
<br />shift. If disparate results are obtained for
<br />particular job classification, sampling
<br />should be repeated. It is advisable to sample
<br />each shift on more than one day to account
<br />for environmental variables (wind, precipita-
<br />tion, etc.) which may affect sampling. Dif-
<br />ferences in exposures among different work
<br />shifts may indicate a need to improve work
<br />practices on a particular shift. Sampling re-
<br />sults from different shifts for each job classi-
<br />fication should not be averaged. Multiple
<br />samples from same shift on each battery
<br />may be used to calculate an average expo-
<br />sure for a particular job classification.
<br />B. Analysis.
<br />1.All extraction glassware is cleaned with
<br />dichromic acid cleaning solution, rinsed with
<br />tap water, then dionized water, acetone, and
<br />allowed to dry completely. The glassware is
<br />rinsed with nanograde benzene before use.
<br />The Teflon cups are cleaned with benzene
<br />then with acetone.
<br />2.Pre-weigh the 2 ml Teflon cups to one
<br />hundredth of a milligram (0.01 mg) on an
<br />autobalance AD 2 Tare weight of the cups is
<br />about 50 mg.
<br />3.Place the silver membrane filter and
<br />glass fiber filter into a 15 ml test tube.
<br />4.Extract with 5 ml of benzene for five
<br />minutes in an ultrasonic cleaner.
<br />5.Filter the extract in 15 ml medium glass
<br />fritted funnels.
<br />6.Rinse test tube and filters with two 1.5
<br />ml aliquots of benzene and filter through the
<br />fritted glass funnel.
<br />7.Collect the extract and two rinses in a 10
<br />ml Kontes graduated evaporative concen-
<br />trator.
<br />8.Evaporate down to 1 ml while rinsing the
<br />sides with benzene.
<br />9.Pipet 0.5 ml into the Teflon cup and
<br />evaporate to dryness in a vacuum oven at 40
<br />°C for 3 hours.
<br />10.Weigh the Teflon cup and the weight
<br />gain is due to the benzene soluble residue in
<br />half the Sample.
<br />II.MEDICALSURVEILLANCEGUIDELINES
<br />A. General. The minimum requirements for
<br />the medical examination for coke oven
<br />workers are given in paragraph (j) of the
<br />standard. The initial examination is to be
<br />provided to all coke oven workers who work
<br />at least 30 days in the regulated area. The
<br />examination includes a 14″ × 17″ posterior-an-
<br />terior chest x-ray reading, pulmonary func-
<br />tion tests (FVC and FEV 1.0), weight, urinal-
<br />ysis, skin examination, and a urinary
<br />cytologic examination. These tests are need-
<br />ed to serve as the baseline for comparing the
<br />employee’s future test results. Periodic
<br />exams include all the elements of the initial
<br />exam, except that the urine cytologic test is
<br />to be performed only on those employees
<br />who are 45 years or older or who have worked
<br />for 5 or more years in the regulated area;
<br />periodic exams, with the exception of x-rays,
<br />are to be performed semiannually for this
<br />group instead of annually; for this group, x-
<br />rays will continue to be given at least annu-
<br />ally. The examination contents are min-
<br />imum requirements; additional tests such as
<br />lateral and oblique x-rays or additional pul-
<br />monary function tests may be performed if
<br />deemed necessary.
<br />B. Pulmonary function tests.
<br />Pulmonary function tests should be per-
<br />formed in a manner which minimizes subject
<br />and operator bias. There has been shown to
<br />be learning effects with regard to the results
<br />obtained from certain tests, such as FEV 1.0.
<br />Best results can be obtained by multiple
<br />trials for each subject. The best of three
<br />trials or the average of the last three of five
<br />trials may be used in obtaining reliable re-
<br />sults. The type of equipment used (manufac-
<br />turer, model, etc.) should be recorded with
<br />the results as reliability and accuracy varies
<br />and such information may be important in
<br />the evaluation of test results. Care should be
<br />exercised to obtain the best possible testing
<br />equipment.
