Dear Mr. Young: I n caso it has not already cone to your attention, v;e ere enclosing a copy of tho "Tentative Ifygicne and Sanitation Standards prescribing Maximum Allowable Concentration Limits of posed by the Hew Jersey Department of Labor. As a research organisation, it is not the Foundations function to trie up positions on legal matters but rather to find and to develop facts in industriel health for the guidance of its Mcr.bor Companies. Acco dingily, .an analysis of the proposed code, from the technical standpoint, will be provided upon request from I-K-F Member Companies. Very truly your 3 ocx Mr. C- Simpson -- --- . if if Managing Director TENTATIVE HYGIENE AND 3AilITATION STANDARDS RULES AND REGULATIONS prescribing MAXIMUM ALLOWABLE CONCENTRATION LIMITS of HARMFUL VAPORS, GASES, FUMES, MISTS, DUSTS and RADIANT ENERGY for Places of Employment Hygiene and Sanitation Section Bureau of Engineering DIVISION OF ENGINEERING AND SAFETY Director: C. George Krueger, Deputy Commissioner of Labor Trenton 8, N.J. November 15, 1945 1 Scone r.nd Purpose 1.1 The allowable concentration limits of vapors, gases, fumes, mists, dusts, and radiant energy apply to all places of employment and shall not be exceeded. -1.2 The purpose of these rules and regulations is to prescribe the permissible concentration limits of vapors, gases, fumes, mists, dusts, and radiant energy in the atmosphere of places of employment for guidance in establishing control procedures for the protection of the health of workers. ?. - Definitions 2.1 Approved - approved by the Commissioner of Labor or any of his authorized r vpresentative s. 2.2 Dusts - solid particles generated by handling, crushing, grinding, rapid impact, detonation or decrepitation of organic or inorganic materials such as rock, ore, metal, coal, wood, grain. 2.3 Fames - solid particles generated by condensation from the gaseous state generally after volatilization from metals and often accompanied by a chemical reaction such as oxidation. 2.4 Gases - normally formless fluids which occupy the space of enclosure and which can be changed to the liquid or solid state only by the combined effect of increased pressure and decreased temperature. 2.5 Harmful - any mechanical or toxic action which in any way injures any part of the body or reduces the normal function of any part of the body in efficiency cue to the effect of vapors, gases, fumes, mists, dusts, radiant energy or environ mental condition, arising from any industrial operatioh or process. 2.6 Mists - suspended liquid droplets generated by condensation from the gas eous state or by breaking up a liquid into a dispersed state, such as by splashing, foaming or atomizing. 2.7 Vapors - the gaseous form of substances which arc normally in the solid or liquid state and which can be changed to these states either by increasing the pres sure or by decreasing the temperature. 7 - Maximum Permissible Concentration Limits 3.1 The maximum allowable concentration limits of vapors, gases, fumes, mists, dusts, or radiant energy for an exposure not to exceed eight hours daily shall be as 3horn in the following table: GA8E3 - parts per million (by volume) at 25 C. and 760 mm pressure - p.p.ra.

Tesbinrr and A n aly sis 4*1 Sampling, testing and analysis of air to determine concentrations of vapors, gases, fumes, mists, dusts, or radiant energy shall be performed by tech nically qualified rnd competent persons only. -3 - 4.2 Sampling, testing and analytical procedure shall be in accordance with approved applicable and reliable methods. ' 4 . 3 The collection of the sample or testing of air shall be made in such a way that the atmospheric conditions at the location of sampling or testing shall not be appreciably changed. 4.4 Except for radiation surveys, samples of air shall be taken at the breath ing level, close to the mouth or nose of the worker with special attention to location near the source of the contaminant and in the path of air currents carrying it toward the vrarker if such conditions exist. 4.5 Samples shall be token in sufficient number to reveal differences in con centration of the contaminant during the working period. 4.6 Samples of air shall be taken wherever there is a known or suspected source of, or exposure to any harmful vapor, gas, fume, mist or dust. 4.7 Radiation surveys shall be made wherever there is a known or suspected source of, or exposure to harmful radiant energy. 5 - Harmful Exposure 5.1 Any process, material or condition that either is known to -be harmful or in which concentrations of harmful substances exceed the values specified in these rules and regulations shall neither be used nor permitted to be used in .any place of employment unless reasonably effective devices, moans or methods shall be pro vided to prevent the contraction of -any illness or disease incident to the work or process.
