The comments are derived from a study made by key people in Operations, Maintenance, Engineering, R&D and Safety. Subparts A-B-C do not presently require study. Comments on Subparts D-E-F were issued as Distribution No. 1, dated August 31, 1971. Later distributions will be issued for revisions and/or to cover the remaining subparts which go through Subpart S. The Baton Rouge plant is not, or may not be, in compliance with the following Federal Occupational Safety and Health Standards.

Remarks: OSHA standards call for design and construction to be in accordance with definitive codes of a specific year such as 1968. We find two things wrong with such dates. First, we have tanks built many years prior to 1968. Second, flexibility is not provided to use standards revised and republished subsequent to 1968. The incorrectness in the use of specific dates should be pointed out to OSHA so that the permanent standards that will be promulgated in 1973 will be correct. By means of this memorandum, Mr. Bergin is asked for advice on how to get the changes made. >A?^z tt8 sa/D APSOVATC %0*K.eCT/oHs vv/u B MAPS vS/7 *</S /s oS Q Par.1910.106(b)(2)(v)(h) Flammable and Combustible Liquids - "Each commercial tank venting device shall have stamped on it the opening pressure, the pressure at which the valve reaches the full open position, and the flow capacity at the latter pressure expressed in cubic feet per hour of air at 60F and at a pressure of 14.7 PSIA.

S 1910.93 Air contaminants. An employee's exposure to any mate rial listed In table G-l, G-2. or G-3 of this section shall be limited in accord ance with the requirements of the follow ing paragraphs of this section. (a) Table G-l: (1) Materials with names preceded by "C"--Ceiling Values. An employee's ex posure to any material in table G-l. the name of which is preceded by a "C" (e.g.. C Boron trifluoride), shall at no time exceed the celling value given for that material in the table. (2) Other materials--8-hour time weighted averages. An employee's expo sure to any material in table G-l. the name ol which is r.ot preceded by "C", in any 8-hour work shift of a 40-hour work week, shall not exceed the 8-hour time weighted average given for that material In the table. (b) Table G-2: (1) 8-hour time weighted averages. An employee's exposure to any material listed in table G-2. in any 8-hour work shift of a 40-hour work week, shall not exceed the 8-hour time weighted average limit given for that material in the tabic. (2) Acceptable ceiling concentrations. An employee's exposure to a material listed in table G-2 shall not exceed at any time during an 8-hour shift the ac ceptable ceiling concentration limit given for the material in the table, except for a time period, and up to a concentration not exceeding the maximum duration and concentration allowed in the column under "acceptable maximum peak above the acceptable ceiling concentration for an 8-hour shift". (3) Example. During an 8-hour work shift, an employee may be exposed to a concentration of Benzene above 25 p.p.m. (but never above 50 p.p.m.) only for a maximum period of 10 minutes. Such ex posure must be compensated by expo sures to concentrations less than 10 p.p.m. so that the cumulative exposure for the entire 8-hour work shift does not exceed a weighted average of 10 p.p.m. (c) Table G-3: An employee's expo sure to any material listed in table G-3, in any 8-hour work shift of a 40-hour work week, shall not exceed the 8-hour time weighted average limit given for that material in the table. <d) Computation formulae: (1) (i) The cumulative exposure for an 8-hour work shift shall be computed as follows: gsc.r.+cr+ . .. c.t. where: a S is the equivalent exposure tor the work ing shift. C Is the concentration during any period of time r where the concentration remains constant. T is the duration in hours of the exposure at the concentration C. The value of E shall not exceed the 8hour time weighted average limit in table G-l. G-2, or G-3 for the material involved. <ii) To illustrate the formula pre scribed in subdivision (i) of this subpara graph, note that isomyl acetate has an 8-hour time weighted average limit of 100 p.pjn. (table G-l). Assume that an employee is subject to the following exposure: Two hours exposure at ISO p.p.m. Two hours exposure at 75 p.p.m. Four hours exposure at SO p.p.m. Substituting this information In the formula, we have 2X160 +2 X 75 +4 X 50 ---------------------------- :-------- =81 p.pm. 8 loo Since 81 p.pm. is less than eight, the 8hour time weighted average' limit, the exposure is acceptable. (2) (1) In case of a mixture of air con taminants an employer shall compute the equivalent exposure as follows: O, C, >=--+--+ Cm Im Where: Em is the equivalent exposure for the mixture. C is the concentration of a particular con taminant. L Is the exposure limit for that contami nant, from table 0-1. 0-2, .or 0-3. The value of E* shall not exceed unity (1). (ii) To illustrate the formula pre scribed in subdivision (i) of this subparagraph. consider the following exposures: Material Actual con centration el S-hour exposure S-hour time weighted aecrace exposure limit Acciona (Table 0-1)___ 1.000 p.p.m. 2-Butanone (Tabic G-l) ... 15 p.p.m___ 200 p.p.m. Tolurno (Table G-2)___ 200 p.p.m. Substituting in the formula, we have: E- 600+ 45+ 40 1,000-^200+"200 >-0500 + 0225 + 0200 >-0925 Since Em is less than unity (1), the expo sure combination is within acceptable limits. (e) To achieve compliance with para graph (a) through (d) of this section administrative or engineering control: must first be determined and imple mented whenever feasible. When suck controls are no: feasible to achieve full compliance, protective equipment or any other protective measures shall be used to keep the exposure of employees to air contaminants within the limits pre scribed in this section. Any equipment and technical measure use for this pur pose must be approved for each particu lar use by a competcnt industrial hygien ist or other technically qualified person. Whenever respire tors arc used, their use shall comply with i 1913.134 of this chapter.

An example of the method of calculating this volume Is given below. Example: To determine the lower explo sive limits oI the most common solvents used in spray finishing, see .Table G-ll. Column 1 gives the number of cubic feet of vapor per gallon of solvent and column 2 gives the lower explosive limit (LEL) in percentage by yolume of air. Note that the quantity of sol vent will be diminished by the quantity of solids and nonflammable: contained in the finish. To determine the volume of air In cubic feet necessary to dilute the vapor from 1 gal lon of solvent to 25 percent of the lower explosive limit, apply the following formula: 4 (100-LEL) (cubic feet of vapor per gallon) Dilution volume required per gallon of solvents LEL Using toluene as the solvent. (1) LEL of toluene from Table G-ll, col umn 2, Is 1.4 percent. (2) Cubic feet of vapor per gallon from Table G-ll, column 1. Is 30.4 cubic leet per gallon. * (3) Dilution volume requlred= 4 (100-1.4) 30.4 --------------------------- =8,564 cubic feet. 1.4 (4) To convert to cubic feet per minute of required ventilation, multiply the dilution volume required per gallon of solvent by the number of gallons of solvent evaporated per minute.

(iil) (a) When an operator must position himself in a booth downstream of the object being sprayed, an air sup plied respirator or other type of respira tor approved by the Eureau of Mines, U.S. Department of the Interior (see 30 CFR Part 11) or specified In ANSI Z88.2-1969 for the material being sprayed should be used by the operator. lb) Where downdraft booths Hre pro vided with doors, such doors shall be closed when spray painting. (7) Make-up air. (i) Clean fresh air, free of contamination from adjacent in dustrial exhaust systems, chimneys, stacks, or vents, shall be supplied to a spray booth or room in quantities equal to the volume of air exhausted through the spray booth. (ii) Where a spray booth or room re ceives make-up air through self-closing doors, dampers, or louvers, they shall be fully open at all times when the booth or room is in use for spraying. The velocity of air through such doors, damp ers, or louvers shall not exceed 200 feet per minute. If the fan characteristics are such that the required air flow through the booth will be provided, higher velocities through the doors, dampers, or louvers may be used. (iil) (o) Where the air supply to a spray booth or room is filtered, the fan static pressure shall be calculated on the assumption that the filters are dirty to the extent that they require cleaning or replacement. (b) The rating of filters shall be governed by test data supplied by the manufacturer of the filter. A pressure gage shall be installed to show the pres sure drop across the filters. This gage shall be marked to show the pressure drop at which the filters require clean ing or replacement. Filters shall be re placed or cleaned whenever the pressure drop across them becomes excessive or whenever the air flow through the face of the booth falls below that specified in Table G-10. (iv) (a) Means of heating make-up air to any spray booth or room, before or at the time spraying is normally per formed. shall be provided in all places where the outdoor temperature may be expected to remain below 55* F. for appreciable periods of time during the operation of the booth except where adequate and safe means of radiant heating for all operating personnel affected is provided. The replacement air during the heatifig seasons shall be maintained at not less than 65* F. at the point of entry into the spray booth or spray room. When otherwise un heated make-up air would be at a tem perature of more than 10* F. below room temperature, its temperature shall be regulated as provided in section 3.6 of ANSI Z9.2-1960. (b) As an alternative to an air re placement system complying with the preceding section, general heating of the building in which the spray room or booth is located may be employed pro vided that all occupied parts of the building are maintained at not less than 65* F. when the exhaust system Is in operation or the general heating system supplemented by other sources of heat may be employed to meet this require ment. (c> No means of heating make-up air shall be located in a spray booth. (d) Where make-up air is heated by coal or oil, the products of combustion shall not be allowed to mix with the make-up air, and the products of com bustion shall be conducted outside the building through a flue terminating at a point remote from all points where make-up air enters the building. (e) Where make-up air is heated by gas, and the products of combustion, are not mixed with the make-up air but are conducted through an independent flue to a point outside the building remote from all points where make-up air en ters the building, it is not necessary to comply with (/) of this subdivision. (/) Where make-up air to any manu ally operated spray booth or room is heated by gas and the products of com bustion are allowed to mix with the supply air, the following precautions' must be taken: (1) The gas must have a distinctive and strong enough odor to warn workment in a spray booth or room of its presence if in an unbumed state in the make-up air. (2) The maximum rate of gas supply to the make-up air heater burners must not exceed that which would yield in excess of 200 p.p.m. (parts per million) of carbon monoxide or 2,000 p.p.m. of total combustible gases in the mixture if the unburned gas upon the occurrence of flame failure were mixed with all of the make-up air supplied. 13) A fan must be provided to deliver the mixture of heated air and products Occupotionol Sofety & Heolth Reporter 20 ^ s./,r/7Z. - j-ov* /=-/e n ' 7/, E--02493 to 00 CO V* u bp EXHIBIT "D" S-9 31:5905 ^ v, &3J-UC7 al '1910.145 Specifications fur unidciil 1 prevention iictii and lufti.
