The objective of this edition is to assemble in one list all chemicals identified as having carcinogenic activity as reported in the literature. For the purpose of this compilation, agents causing benign or malignant tumors are classed as carcinogens. This is because of the possibility that agents which cause benign tumors may also produce malignant tumors. This publication is intended to meet general information needs on potential chemical carcinogens as well as to provide the documentation for the list of approximately 1500 chemical substances published by NIOSH in the Federal Register. In the Toxic Substances List program NIOSH, for the past four years, has been collecting and disseminating information on the health effects of chemicals including carcinogenic effects. Last year we conducted a comprehensive review of the primary literature and an accelerated attempt to collect current as well as retrospective information. The 1500 chemical substances identified so far have demonstrated carcinogenic activity from studies reported in the literature. However, no critical evaluation of the test protocol or derived data has been per formed. In addition, the actual presence of the chemical in the workplace has not been determined and no attempt has been made to correlate the test data with the physical state or purity grades of chemicals found there. Thus, NIOSH is requesting additional information for its programs in occupational carcinogens identification and recommended control. This compilation should provide ready reference for potential carcinogenicity of chemicals found in the workplace, and should be useful to occupational health physicians, industrial hygienists, toxicologists, and researchers. A better under standing of potential workplace health problems through the use of this compila tion hopefully will facilitate the achievement of a healthful workplace. John F.

This list contains approximately 1500 chemical substances which were selected from the full toxicological file for their carcino genic effects as determined in whole animal stud ies. For those chemical substances selected, we have included the entire file entry: descriptors, molecular weight, molecular formula, structural notation, synonyms, toxicity data and references, and pertinent occupational standards. The purposes for presenting these data are manifold and serve a variety of uses. This list serves as a single source document for toxic sub stance information; including such data as chem ical properties and standards information for those toxic chemicals for which standards have been promulgated. This presentation of the vari ous types of toxic effects referenced by original studies will allow researchers and occupational health specialists an introduction to the literature, thus facilitating their review of the toxic hazards of a substance. Through the collection and pre sentation of the lowest reported doses by several routes and various species, valuable information is made available to those who have responsibility for preparing safety data sheets for chemical substances in the workplace. Through the use of this list, chemical and production engineers can identify the relative hazards which may be asso ciated with the use of chemical intermediates for the development of final products and, thus, can determine the use of substitutes or alternate proc esses which may be less hazardous. By using various indexes in the automated file, association of chemical structure to the toxic effects produced by a chemical may be possible and, thus, enable some prediction of what to expect from a newly synthesized chemical. In offering this edition we recognize its limi tations in achieving the purpose that we have set for it. First, it may not include all demonstrated carcinogenic substances. Such a goal can not be achieved without the full cooperation of the sci entific community. Cooperation in the form of personal contributions will become increasingly imperative as the list becomes more nearly com plete. The absence of a substance from this list does not imply that a substance is not a carcinogen; only extensive testing would lead to that con clusion. It must be reemphasized that the entry of a substance on the list does not automatically mean that it must be avoided. A listing does mean, however, that the substance has the po tential of being hazardous if misused and, there fore, care must be exercised to prevent tragic consequences. Thus, there will be found on the list many substances which are common in every day life and are in nearly every household in the United States. It is not the purpose of the list to quantitate the hazard through the use of the toxic concen tration or dose that is presented with each sub stance. No attempt has been made to resolve any question about data that have been published. Of necessity, we rely on editing provided by the scientific community prior to any publication in scientific literature. Under no circumstance can the toxic dose values presented with these chem ical substances be considered as being definitive values for describing safe concentrations for hu man exposure. Concentrations of chemical sub stances in man's working environment which may be safely tolerated can be determined only by a critical evaluation of all available pertinent data by experienced investigators. A critical evaluation of a chemical hazard involves much more than a determination of the toxic potency, no matter how complex the deter ti a a mination may be. A ha2ard evaluation must include such a determination, of course, but toxic potency and degree of hazard can not be con sidered as being synonymous. Identifying and defining a chemical hazard must also include the evaluation of the amount and duration of expo sure, the physical characteristics of the substance, the physical conditions under which exposure oc curs and the determination of the presence of other chemical substances. All of these may sig nificantly alter the toxic potency of a substance which, in turn, may alter the health of the person who may become exposed. NIOSH, under its criteria development pro gram, conducts critical reviews of occupational hazards. The resulting criteria document thereby provides a valid detailed support for the standard as recommended by NIOSH for the Department of Health, Education, and Welfare to be used by the Department of Labor as a basis for its promul gation of a standard. The standards referenced in this list as U.S. Occupational Standards (U.S.O.S.) state the con centrations of substances which have been deter mined to provide a safe, healthful work environ ment for all persons. These may also include, within the limits of technical feasibility and in accord with such other considerations as made by the U.S. Department of Labor, methods for sampling and analyzing; engineering controls; appropriate personal protective equipment and clothing; emergency procedures; medical surveil lance procedures; use of signs, labels, and placards to identify the hazardous substances; and the requirement for apprisement of the workers of the hazard to which they are exposed. A standard for an occupational exposure to vinyl chloride was promulgated under The Occu pational Safety and Health Act during 1975. AH standards appear in the Appendixes. As of the date of publication of this list, there have been 23 criteria documents for recommended standards forwarded to the Department of Labor. A list of these documents appear in Appendix VI. The Williams-Steiger Occupational Safety and Health Act of 1970 in Section 20(a) (6) directs that the Secretary of Health, Education, and Welfare ". . . shall determine following a written request by any employer or authorized representa tive of employees . . . whether any substance normally found in the place of employment has potentially toxic effects in such concentrations as used or found . . . ." The manner of implementing this activity is found in 42 CFR Part 85, in the Federal Register volume 37, number 215, pages 23639 through 23642, November 7, 1972. Both the reference and the forms to be used in requesting assistance from NIOSH are found as Appendix VII. The Toxic Substances List, by providing a convenient mechanism for recognizing potentially hazardous chemicals, may assist those interested in identifying the substances in the workplace which may be hazardous to health. We request and will appreciate whatever assistance may be offered by representatives of the industrial, academic, and governmental com munities in supplying data for this list. This assistance may be offered in the form of reprints of scientific publications, of technical data sheets, of sales or promotional material, or any other pub licly available reference material, of data pre sented by personal letter for previously unpub lished studies or by notification of errors. All material received will be considered as part of the public domain and as such may be made available to any persons or organizations. vm VRD 000202595? CRITERIA FOR THE TOXIC SUBSTANCES LIST Selection 1. Substances. For the purpose of this list the phrase "all known substances" that exhibit car cinogenic activity was interpreted to include all mined, manufactured, processed, synthesized and naturally occurring inorganic and organic com pounds. The list may include drugs, food addi tives, preservatives, ores, pesticides, dyes, deter gents, lubricants, soaps, plastics, extracts from plant and animal sources, plants and animals which are carcinogenic by contact or consump tion, and industrial intermediates and waste prod ucts from production processes. 2. Substances Excluded. Excluded from The Toxic Substances List file and, therefore, this publication were trade name products represent ing compounded or formulated proprietary mix tures available as commercial products. These exclusions were necessary because of difficulties in assessing the contribution to the toxicity by each component of the mixture and because the com ponents of those formulations can be and are often changed by the producer by substitu tion of different chemicals with different toxic effect potential or through varying the concen trations. Trade names have been included on the list where they represent a single active chemical entity. These substances may be impure com mercial products of relatively constant composi tion and will be identified by definitions of com positions rather than by a Chemical Abstracts Service Registry Number, molecular formula or Wiswesser Line Notation. Radioactive substances are now included but the effect reported is due to the chemically produced effects rather than to the radiation effects. Format 1. General. The list is made up of a series of toxic substance items which are arranged in alphabetical order. Each name is preceded by a seven character code consisting of two letters of the alphabet followed by five digits. The number code varies directly with the alphabetic sequence of the substance name on the list and will not change in subsequent revisions except where se quence errors are discovered and must be cor rected. Following the name of the chemical sub stance are lines containing definitive descriptions of the synonymous names, substance, toxic dose information with references, and references to existing and recommended standards and to NIOSH's criteria for recommended standards. Ab breviations used can be identified in the pages that follow or by reference to the glossary on the inside of the front and rear covers. A schematic entry is shown in Figure 1. 2. Substance Prime Name. We have estab lished the prime chemical name of each chemical for this list to be the nomenclature used by the American Chemical Society Chemical Abstracts Service (CAS) in the 8th collective index of chem ical abstracts which is in the inverted form. With this preferred prime name, the reader may find the CAS Registry Number, molecular weight, molec ular formula, Wiswesser Line Notation, syno nyms, toxic data, and other pertinent information. Some entries, however, appear as a chemical or descriptive name as published in the source from which the toxic data were derived. This is par ticularly true for those substances for which some aspects of the composition are in question such as plant or animal extracts. These prime names will be accompanied by a definition or description (DEF:) which may be a narration including the source, a generally accepted statement of constitu ents or other helpful information, with a reference source. Numerals, Greek letters, and prefixes in dicating substituent locations, and stereochemical IX VRD 0002075^53 or other structural features are ignored in the first alphabetical ordering. These components are taken into account for secondary ordering in ascending numerical order and alphabetically within alphabetically similar substances. When the line item entry is a name that is other than a prime name, such as a trade name, common name, or coined name, a cross reference is given to the sequence number and name of the prime entry with the available data. 3. The Chemical Abstracts Service Registry Number, (CAS): is a designation which uniquely identifies a specific chemical compound. The value of such an entry is that it allows one to always conclusively recognize a chemical com pound, regardless of the name or naming system used. The numbers used in this publication were derived from the Desk Top Analysis Tool* (DAT), the Chemical Abstracts Indexes, and various other sources. 4. The Molecular Weight, MW: is calculated from the molecular formula as was presented by the DAT, from the article of reference, or from the formula derived from the name. 5. The Molecular Formula, MOLFM: desig nates the elemental composition of the chemical and is entered according to the rules presented in the DAT. 6. Wiswesser Line Notation, WLN: was as signed when available. The WLN is a line-form ula chemical notation describing in a concise and precise manner the structural formula of a chem ical compound. This formula enables substructure searches for special functional groups and sub stituents that are found in this molecule. The WLN descriptions will allow machine retrieval of entries by chemical characteristic which may facil itate analysis. It also should aid in recognition of certain substructure-activity relationships. 7. Synonyms, SYN: This line is devoted to synonyms for the prime name substance listed. All synonyms found will be listed in alphabetical order following "SYN:" according to the same rules presented for ordering the substance on the first line. Each name will be separated by an asterisk. Synonyms are other chemical names, trade names, common or generic names. 8. Toxic Dose Data, (see Figure 2.) This section contains the toxic dose or concentration and the result that qualified the substance for inclusion as a potential carcinogen on the list. Desk Top Analysis Tool for the Common Data Base (6 volumes) 1968: NTIS**PB 179-900. Additional lines of toxic dose information for other routes of administration, for other effects, or for other species may be present. These are entered as additional information or references in order to more fully define the toxic nature of a sub stance. All of the entries in the toxic dose section contain information entered according to the fol lowing pattern: The first line starts with the notation "TXDS:" immediately followed by the qualifying toxic dose information. The entries then following indicate, in sequence, the route of ex posure; the species of animal involved; the type of dose; the amount of substance per body weight or concentration per unit air volume and, where applicable, the duration of exposure; a descriptive notation for the type of effect reported; and, lastly, the reference source from which the information was extracted. The additional entries after the first line are not preceded by "TXDS." Each ele ment of this further toxic dose data line is dis cussed below. a. Qualifying Toxic Dose (TXDS). All toxic doses appearing on The Toxic Substances List were derived from reports of the toxic effects pro duced by individual substances. A toxic effect is defined as any bodily injury -- reversible or irre versible; any tumor -- benign or malignant; any mutagenic or teratogenic effect; or death which has been reported to have resulted from exposure to a chemical substance via the respiratory tract, skin, eye, mouth, or any other route. For humans the toxic effect is any toxic effect that was reported in the source reference. There is no qualifying limitation to the duration of expo sure nor to the quantity or concentration of the substance, nor is there a qualifying limitation of the circumstances that resulted in the exposure. Regardless of the absurdity of the circumstances that were involved in a toxic exposure, it is assumed that the same circumstances could recur. For a substance to be included, there is no limita tion as to the time of exposure, nor the quantity or concentration of the dose of the substance reported to have caused neoplastigenic, or carcin ogenic effects in animals. This is because a doseeffect relationship has not been correlated for animals and man. It is presumed that there is some potential for the occurrence in man of effects similar to those noted in animals if man is exposed to these substances. For the practical purpose of identifying the substances producing carcinogenic effects, we ac cepted statements by authors that the effects found x FIGURE 1.

TTius, if the effects were reported as being carcinogenic or neoplastigenic by .the author of a report, these reported classifications were ac cepted. A substance is listed as a neoplastigen if one significant tumor was reported according to a classification by the number and type of tumor produced. If a substance was reported to have produced a malignant tumor or one that metasta sized to other parts of the body, the substance is listed as a carcinogen. Although these classifica tions are noted, it is the current policy of NIOSH to classify chemicals as carcinogenic if they pro duced tumors (benign or malignant) in animals. The report of the lowest dose administered over the shortest time to produce the toxic effect was given preference; though some license was taken in order that data cited in different references might be entered. Data from animal experimenta tion resulting in death must be selected and limited by some criteria. All substances, when administered in sufficiently high quantities or con centrations over a sufficient length of time, will cause death. Therefore Table I is included as set- TABLE II ROUTES OF ADMINISTRATION TO, OR EXPOSURE OF, ANIMAL SPECIES TO TOXIC SUBSTANCES Route Intracerebral Intracervical Intradermal Intraduodenal Inhalation Implant Intramuscular Intraplacental Intrapleural Intraperitoneal Intrarenal Intratracheal Intravaginal Intravenous Ocular Oral Parenteral Rectal Skin Subcutaneous Unreported Abbreviation ice icv idr idu ihl imp ims ipc ipl ipr irn itr ivg ivn ocu orl par rec skn scu unk Definition administration into the cerebrum administration into the cervix administration within the dermis by hypodermic needle administration into the duodenum inhalation in chamber, by cannulation, or through mask placed surgically within the body -- location described in reference administration of dose into the muscle by hypodermic needle administration into the placenta administration of dose into the pleural cavity by hypodermic needle administration into the peritoneal cavity administration into the kidney administration into the trachea administration into the vagina administration of dose directly into the vein by hypodermic needle administration directly onto the surface of the eye or into the conjunctival sac per os, intragastric, feeding introduction with drinking water administration into the body through the skin.

Route of Exposure or Administration. Al though most exposures to substances in the indus trial community occur through the respiratory tract or skin, most exposures reported in the published literature concern studies of experimen tal animals in which the test substances were in troduced through the mouth by pills, in food, in drinking water, or by intubation directly into the stomach. Therefore, for purposes of developing infor mation concerning the relative toxicity of sub stances, toxicity studies by all exposure routes are reported. The abbreviations and definitions of the various routes of exposure used in this listing are found in Table II. c. Species Exposed. Since the effects in the human are of primary concern we have indicated, when available, whether the results were observed in man, woman, child or infant. If no indication is made in the reference, the term "human" is used. Results of studies on rats and mice are the most frequently reported, and hence, are the most use ful data for comparative purposes.

Description of Exposure. . In order to de scribe the entered dose more completely, six ab breviations are used. These terms indicate whether the dose caused death (LD) or other toxic effects (TD) and whether it was administered as a lethal concentration (LC) or toxic concentration (TC) in the inhaled air. Their definitions are as follows: TDLo-Toxic Dose Low -- [he lowest dose of a substance, as published or made known to us, introduced by any route other than inhalation over any given period of time and reported to produce any toxic effect in man or to produce carcinogenic, teratogenic, mutagenic, or neoplastigenic effects in humans or animals. TCLo-Toxic Concentration Low -- any con centration of a substance in air to which man or animals have been exposed for any given period of time and that has been reported to produce any toxic effect in man, or to produce a carcinogenic, teratogenic, mutagenic, or neoplastigenic toxic effect in animals or humans. LDLo-Lethal Dose Low -- the lowest dose of a substance other than LD50 introduced by any route other than inhalation over any given period of time and reported to have caused death in man or the lowest single dose introduced in one or more divided portions and reported to have caused death in animals. Entries for lethal doses admin istered to animals for the qualifying toxic dose, TXDS, were made in accordance with the dose limits of Table I. LD50-Lethnl Dose Fifty -- A calculated dose of a chemical substance which is expected to cause the death of 50% of an entire population of an experimental animal species, as determined from the exposure to the substance, by any route other than inhalation, of a significant number from that population. Other lethal dose percentages, such as LD1, LD10, LD30, LD99. may be pub lished in the scientific literature for the specific purposes of the author. Such data would be pub lished in the list if these figures, in the absence of an LD50, were the lowest published in the article. A substance may qualify by an LDLo published value even though a higher LD50 value, which may also exceed the limits of Table I, was re ported in the same publication. LCLo-Lethal Concentration Low -- the low est concentration of a substance, other than an LC50, in air which has been reported to have caused death in man or to have caused death in animals when they have been exposed for 24 hours or less. Entries for lethal concentrations for animals for the qualifying toxic dose, TXDS, were made in accordance with the dose limits of Table I. LC50-Leiha\ Concentration Fifty -- a calcu lated concentration of a substance in air, exposure to which for twenty-four hours or less would cause the death of 50% of an entire population of an experimental animal species, as determined from the exposure to the substance of a significant number from that population. These entries qual ified in accordance with the dose limits set forth in Table I. See LD50 above for other parameters which may similarly apply to entries for the list. e. Units of Dose Measurement. As is found in almost all experimental toxicology studies, the doses are given in terms of the quantity adminis tered per unit body weight or quantity per unit volume of the respired air. In addition, where applicable, the duration of time over which the dose was administered is also listed. The dose, whether it was reported in terms of weight or volume, was entered in terms of units of weight. Milligrams per kilogram (mg/kg) were pre ferred, but in some cases, because of dose sizes, grams per kilogram (gm'kg), micrograms per kilo gram (ug-'kg), or nanograms per kilogram (ng./kg) were used. Volume measurements of dose were converted to weight units by the appropriate calcu lations, assuming all liquids to have a density of one for a conversion of one milliliter to one thou sand milligrams. All body weights have been convened to kilo grams (kg) for uniformity. For those references in which the dose was reported to have been administered to an animal of unspecified weight or a given number of animals in a group (e.g., feeding studies) without weight-data, the weights of the respective animal species were assumed to be those found in Table IV and the dose was listed on a per kilogram body weight basis. For the references in which similar information was presented for man or woman and no weight data were provided, the weight for man was assumed to be 70 kilograms; for woman, 50 kilograms; and for child, 20 kilograms. Assumptions for daily food and water intake are found in Table IV for approximating doses per individual animals where the dose has been exposed as a concentration in food or water. The values presented are selec tions which are reasonable for the species and xvi convenient for dose calculations. These values would be used in lieu of other more exact available data. other measurements of contaminants are used such as fibers or particles, the measurement is not abbreviated but is spelled out, e.g., for asbestos 1.2 fibers/cc.

Data for lifetime exposure are calculated from the assumptions for adult animals for the entire period of exposure. For definitive dose data the reader must review the referenced publication. All concentrations of a substance in air are listed preferably as parts of vapor or gas per million parts of air by volume (ppm). As may be convenient for effective presentation, parts per hundred (pph or per cent), parts per billion (ppb). and parts per trillion (ppt) may be used. If the substance is a solid or a liquid, the con centrations are listed preferably as milligrams (one thousandth of a gram) per cubic meter (mg 'm3) but may, as applicable, be listed as micrograms (one millionth of a gram; 10_,; gram) per cubic meter (ugym3), nanograms (one bil lionth of a gram; 10-" gram) per cubic meter (ng m3), or pico grams (one trillionth of a gram; 10-1- gram) per cubic meter (pg m3), of air. Where the original source listed the concentration measurements of a liquid in volume units, the density of the chemical was assumed to be one thousand milligrams per milliliter and was con verted to milligrams. For those cases in which For some studies, e.g., inhalation, carcinogen, mutagen, teratogen and feeding studies, the dura tion of exposure is pertinent to the dose informa tion. For those studies, time will be presented as indicated in Table V. In all cases the total duration of exposure appears first after the kilo gram body weight and slash followed by descrip tive data; e.g., 10 mg/kg/3WI means ten milli grams per kilogram body weight administered over a period of three weeks, intermittently in a number of separate, discrete doses. It is intended to provide the reader with enough information for an approximation of the experimental condi tions which can be clarified by studying the article cited. f.

These nota tions will indicate the organ system affected or will indicate in the case of animal experiments special properties that the substance demonstrates, e.g., CAR = carcinogen. No attempt was made to be definitive of the effect reported because such definition requires much detailed qualification and is beyond the scope of this publication. The selection of the dose was based first on the lowest dose producing an effect, and secondly, on the latest study published. 9. Cited Reference. The final entry of this line is the reference from which the toxic dose information was extracted. All references from which the information has been gathered are and must be publicly available.

Occupa tional standards found in Appendices I through V of this introduction are those pertaining to subject chemical substances. References to these stan dards are also included in the body of the list under the appropriate chemical substance. The format heading of these reference lines is "U.S. Occupational Standard" followed either by "USOS" or "EPA." "USOS" refers to standards promulgated under section 1910 of the Occupa tional Safety and Health Act of 1970 and "EPA" refers to Worker Protection Standards for Agri cultural Pesticides promulgated under the Federal Insecticide, Fungicide and Rodenticide Act. The references to air contaminants in Appen dix I are expanded to include the numerical limit values. Although more complex, this quantita tive information may be taken along with the unevaluated data to provide a more nearly com plete profile of the chemical. The entry following USOS is "air" which labels this as an air contaminant standard. TWA or Cl refers to either time weighted average or ceiling value. For some chemicals TWA, Cl, and Pk (peak) values are given in the standard. In those cases all three are listed. Finally some en tries may be followed by the designation "(SKIN)."

Contributions were in the form of reprints, preprints, elaborations of conference presentations, and letters containing unpublished data as well as suggested corrections. Reader participation is essential to the development of this list. User participation is potentially far more important than staff effort in collection and evaluation of data in this field. Therefore, in order to improve subsequent editions, both in quality and comprehensiveness, participation is strongly encouraged. We are grateful to those who have contributed. xxi 9 6 S Z 0 0 0 0 <IHA APPENDICES Appendix I RULES AND REGULATIONS 2213$ Subpart G--Occupational Health and Environmental Control 1910.93 Air contaminants. An employee's exposure to any mate rial listed in table Q-l, 0-2, 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 Q-l, the name of which is preceded by a "C" (e.g., C Boron trifluorlde), 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 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 time weighted average given for that material in the table. (b) Table0-2: (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 ceiling concentration limit given for the material in the table, except for a time period, and up to a concentration Thu Uicu issuance of the Occupational Safety and Health Standards contained in Part 1910 of Title 29 of the Code of l ederal Rcgubiiom appeared in the June 27. 1974, mue of the ledcrai Register. Volume 39, Number 123. Part II. beginning with page 23.02. 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.pm. (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.pjn. so that the cumulative exposure for the entire 8-hour work 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 not exceed the 8-hour time weighted average limit given lor that material in the table. (d) Computation formulae: (1) (i) The cumulative exposure for an 8-hour work shift shall be computed as follows: *s=C*T4-fCr + . . . CnTm Where: 8 B Is the equivalent exposure for the work ing shift. C Is the concentration during any period of time T where the concentration remains constent, T Is the duration In hours of the exposure at the concentration C.

(li> To Illustrate the formula pre- acrlbed In subdivision (l) of this subpara graph. note that isoamyl acetate has an 8-hour time weighted average limit of 100 p.p.m, (table 0-1). Assume that an employee id subject to the following exposure: Two hours exposure at 150 p.p.m. Two hours exposure at 75 p.p.m. Pour hours exposure at SO p.p.m. Substituting this information in the formula, we have 2x150 + 2x75+4x50 ------------------------------------------=81.25 p.p.m. 8 Since 81.25 p.p.m. is less than 100 p.p.m., 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: c, c. c- Ei -----1--- + . . . -- L, L, Lm Where: E* 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).
