An employee's exposure to any mate rial listed In table 0-1, 0-2, or G-3 of this section shall be limits m accord ance with the requirements of the follow ing paragraphs of thu section. <*) Table 0-2: (1) Materials with names preceded bv "C--Ceiling Values. An employee's ex posure to any material In table 0-1, the name of which is preceded by a "C" (ejr,, C Boron trlfluonde), *> at no exceed the value given lor that material In the table. <2) Other materials--8-hour time weighted averages. An employee's expo sure to any material in table 0-1, 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 t.tme weighted average given for that material In the table. (b) Table 0-2: (1) 8-hour time weighted averages. An employee's exposure to any material listed in table 0-2, 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 0-2 shall not exceed at any time during an 8-hour shift the ac ceptable celling 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 concentration for an 8-hour shift". (3) example. During an 8-hour wort shift, an employee may be exposed to a concentration of Benzene above 25 p.pjn. (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 leas than 10 p.pjn. so that the cumulative exposure for the entire B-hour woik shift does not exceed a weighted average of 10 p.pjn. (c) Table 0-3: An employee's expo sure to any material listed in table 0-3. In any 8-hour work shift of a 40-hour work week, shall cot exceed the 8-hour time weighted average limit given for that material in the table. (d) Computation formulae: (1X1) The cumulative exposure for an 8-hour work shift shall be computed as follows: g=c.r.+c*r*+ . . . c.r. s when: X la the equivalent expoaure for the work ing shift. C la the concentration during any period of time T where the concentration remains constant. T la the durstiub In hour* of the expoeure at the concentration C. The value of E shall not exceed the 8hour time weighted average limit In table 1219-74 Copyright 6 1974 by The Bureau of Notional Affairs, Inc. [Sec. 1910.93(d)] 55 RSV 00113^8 31:5302 REFERENCE FILE 0-1, Q-2, or 0-3 for the material Involved. <11> To Illustrate the formula pre scribed in subdivision U) of this subpara graph. note that lsoamyl acetate has an 3-hour time weighted average limit of 100 p.pm. (table 0-1). Assume that an employee is subject to the following exposure: Two botxn cspoaura it 160 p.pxa. Two boon u|wuw it 78 p.pn. Four Pours exposure at 60 P4un. Substituting Information In formula, we have 9X160+ 9 X 76 +4 X 50 =IUt p-p-m. e Since 81.35 p.pjn. is leas than 100 p.pm.. the 5-hour time weighted average limit, the exposure is acceptable. (3) (1) In ease of a mixture of air con taminants an employer compute the equivalent exposure as follows: r Where: L, ^ L. I* is tbs equivalent exposure for tbe mixture. C la the concentration of a particular oontamtnent. lU tbe exposure limit for that contami nant, from table 0-1, 0-3. or 0-6. The value of shall not exceed unity (1). (h) To illustrate the formula preecilbed in subdivision (1) of this sub- paragraph, consider the following exposures: UaeU Actual aon* mntraaoe SepHeoonr Mtoor Urn* wIaTtcWhtaId ewnwitw letcM (Tabl* 0-1)........... fOOp.p.m... 1,400 p.pjn HaUiim (Table ^l),,. 44 p.pjn.... 300 p.p.m. TMaaaa (TabU 0-2)............40 P-Pd____ 600 p.pjn. - Substituting in the formula, we have: 500 46 40 *-=--------+ + 1X00 900 900 *-=0.500+0.234+0.300 *.=0*36 Since E. Is lew than unity (1), the expo sure combination la within acceptable ifcniti. (e) To achieve compliance with para graph (a) through <d) of this section, administrative or engineering controls must first be determined and Imple mented whenever feasible. When such controls are not feasible to achieve full compliance, protective equipment or any other protective measures shaij be used to keep the exposure of employees to air contaminants within the limits pre scribed In this section. Any equipment and/or technical measures used for this purpose must be approved for each par ticular use by a competent Industrial hygienist or other technically qualified person. Whenever respirators are used, their use shall comply with 11910.134. Tabls G--1 Acrulrtrhrdc................. . 300 Aertor.e........................................
