Scope; Purpose; Availability of Pertinent Reference Scppe: This regulation appllei to <11 places of employment In Texsi. It does not cover maximum permlaalble dote of radiation or the mi n i m a environmental sanitation requirement a, nor In clude assures required for control of community external air pollution or air pollution nuisances. Purpose: The purpose of this regulation it to prescribe to employers the bi xin.rm average atmospheric concentration of contaminants to which they era permitted to exposa employees during an eight-hour working day in their places of employment. In cluding industrial establishment*. Pertinent References: Copies of related laws, regulation*, opinion* of tha Attorney General of Taxes, and Advisory Standards currently applicable will ba provided to any citizen of Tax** upon requeit. ' II. Applicability of Figures Listed Herein Individual paopla react differently afear exoaislva exposure* Co atmospheric concentrations of cent minante in placas of employment. Listed herein ere weighted avaraga concentrations generally safe In place* of employment during an eight-hour working exposure. These are not maximum values which cannot be exceeded momentarily depending upon, but not limited to, such factors a* natura of contaminant; frequency of occurrence of high concentration; verlabia durations of exposure; probability of acuta poisoning from high concentration for even short period*; cumulative affects. Employers shall consider these factors prior to exceeding valuee listed herein. III. Reviion Values listad herein ara basad upon Information obtained from recant experience, experimental study reports, or a combination of tha two. Regular review will result in revisin aa Justified. Tha State Hoard of Haelth solicit* and will consider pertinent date beaed upon facts and experience received from individuals, industrias, governmental agencies, or otbara. IV. Definition 1. Induatrlal Establishment Is defined to mean an Institution, a place, building or location relatad to manufactures or to the product of Industry or labor. 2. Place of Employment la defined to mean any place where two or more persons era directly or Indirectly employed by another for direct oc indirect gein or profit. - 2 - v .

BONNET 1 * PITTSBURGH OFFICE TO . INDUSTRIAL HXGIMISTS March 28, 1973 RE: OSHA CITATIONS________ ___________________________ _ _ _ ____________ _______ An OSHA Industrial hygienist surveyed our Warrick Operations during the month of January. As a result, eight citations were issued for violations of exist ing standards. We thought that all of you would be interested in the items cited which, except for items $ and #8, concerned themselves with exposures to noise and asbestos. We are alerting you to this action to show where -some of the interest of OSHA presently lies and to point out that many of us also are vulnerable in these two areas. We trust that all will benefit from Warrick's misfortune. t The penalties imposed are of small concern when compared to the cost of cor recting the conditions for which they were cited. It is of special interest to note that Warwick was cited, not only for failing to require ear protection i n the noisy areas, but also for their failure to institute engineering or administrative ct ntrols or to document the infedibility of such controls.
