The connents are derived from a study made by key people in Operations, Maintenance, Engineering, RAD and Safety. Subparts A-B-C do not presently require study. Connents 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, (The study shows compliance with all other such standards in subparts included in this study applicable to the Baton Rouge plant.) /& 'frS/nu>fi a-l '/ / CZO>-c(f ts/fPsn /J S'C<` /Tlesno . tt^mcAc-e/ fre*n fA J> 75 SUBPART G - OCCUPATIONAL HEALTH AND ENVIRONMENTAL CONTROL Standard Par.1910.93 "Air Contaminants."

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.

However, we feel that this standard does not apply to us since the Ethyl plant is a chemical plant and chemical plants are exempt. "Piping containing flammable or combustible liquids shall be identified." Ben Hodge attended an OSHA workshop in New Orleans 9/21/71. He said that identification requirements were under development by OSHA and more information would be forthcoming. The writer recommends status quo until more details are received from OSHA.

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, fa) Table G-l: (1) Materials with names preceded hv "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. C2) Other materials--S-hour time weighted averages. An employee's expo sure to any material in table G-l, the name of which is not 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) S-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 table. (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 scccptable 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.pra. c (but never above 50 p.p.m.) only for a maximum period of 10 minutes. Such ea rn posure must be compensated by expo rt sures to concentrations` less thsn 10 p.pjn. 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 tabic 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) (1) The cumulative exposure for an 8-hour work shift shall be computed as follows: *=<7.r.+cr.+ ... c.r. where: 8 X Is the equlvelent exposure for the work ing ehtft. C is the concentration during any period of time T where the concentration remain* constant. T is the duration in hour* of the exposure et the concentration C. The value of shall not exceed the 8hour time weighted average limit in table G-l, G-2, or G-3 for the material involved. (il) 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 150 p.p.m. Two hours exposure at 75 p.p.m. Four hour* exposure at 50 p.p.m. Substituting this information In the formula, we have 2X150+2 X 75 +4 X 50 - - -- - -- - =ti p.pm. " . I0O Since 81 p.p m. is less than eight, the 8- hour time weighted average' limit, the exposure is acceptable. (2> (i> In case of a mixture of air con taminants an employer shall compute the equivalent exposure as follows: Where: E=--+~ K t| o* U E- Is tha equivalent exposure for the mixture. C is the concentration of a particular con taminant. t 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). (11) To illustrate the formula pre scribed In subdivision (1) of this sub paragraph. consider the following exposures: Material Actual ran.

(e) To achieve compliance with pan graph (a) through (d) of this sectio gdministrative or engineering ccatr* must first be determined and lmplt merited whenever feasible. When sue controls arc not feasible to achieve fu compliance, protective equipment r an other protective measures shall be use to keep the exposure of employees to ai contaminants within the limits pie scribed In this section. Any equipmen and technical measure use for this pur pose must be approved for each particu lar use by a competent industrial hygien ist or other tochnkally qualified person Whenever respirators arc used, their use shall comply with 11913.134 of this chapter.

(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.

The replacement air during the heatiflg 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 work- ment 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. (parte per million) of carbon monoxide or 2,000 p.pjn. 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.
