INDUSTRIAL PUBLIC HEALTH HAZARDS The Public Health Council of the State of Chio hereby ordains and promulgates the following regulations for the prevention and control of diseases resulting from exposure to toxic fumes, vapors, mists, gases and dusts in order to preserve and protect the public health. Regulation 244. (Application of Regulations). These regulations shall apply to every place of employment and particularly to those places of employment where a work or process is carried on by which dusts, fumes, mists, vapors, gases or environmental conditions of a harmful nature are produced or generated, or exist independent-y of the work or process, which may be inhaled or absorbed or in any other manner enter the body in quantities or concentrations that constitute harmful exposure as here inafter defined. Regulation 245. (Modifications). When strict compliance with all of the provisions of these regulations would involve undue hardship, the Ohio Department of Health may, upon application in writing, permit modification of the requirements when protection practically equivalent to that required by these regulations has been provided. The application for the modification of any of these regulations in eny particular case shall be accompanied by a full statement of the existing condi tions and the reasons for requesting such modification. Any modification granted under the provisions of this paragraph shall be limited to the particular case cover ed by the application for such modification. Regulation 246. (Definitions). (1.) A "Gravity System of Ventilation" means one which depends wholly upon relative air density. (2.) A "Mechanical System of Ventilation" means one which depends upon the operation of power-driven equipment, (3.)

(2) The sampling and analysis of contaminated air and the interpretation of the data in relation to the stated maximum allowable concentrations shall be done only by technically qualified and competent persons using methods approved by the Ohio Department of Health. (3) Temporary concentrations in excess of the maximum allowable concentrations listed shall not be permitted if exposure to such concentrations for a period of one hour or less may re stilt in an adverse effect on health, (4) For the purpose of the above maximum allowable concentrations for silica, the free silica content shall be the percent of free silica in the fraction of the air-borne dust in the breathing zone of the worker that is smaller than 5 microns in maximum diameter,. (5) For all other dust determinations millions of dust particles per cubic foot f air by the light field microscope counting technique shall include all microscopically visible particles up to 10 microns in size,"- Regulation 248, (General Ventilation.) Special Requirements:- Wherever harmful concentrations of dust, fumes, mists, vapors or gases exist, or are produced in the course of the employment, and prevention, elimination, or control of said harmful exposures is not practical by local exhaust, or by other means as herein after provided, the capacity of the general ventilation system, be it a gravity or mechanical means of moving air, shall be augmented, or sufficient dilution ventilation provided, so as to provide for the elimination of said harmful exposures to a degree specified under Regulation 24?' Regulation 249, (Local Exhaust Ventilation.) (1.) Where Required:- All equipment and processes that emit or create harmful dusts, fumes, mists, vapors, gases, or other contaminants in quantities that tend to be harmful to the health of the employees exposed thereto, and where general ventilation alone or in conjunction with other provisions of these regulations, is inadequate to furnish the required protection, shall be connected to an exheust system for the removal of said hazards, as far as practicable at their point of origin. Wherever practicable, application of local exhaust ventilation is preferred, (2.) General Requirements:- Exhaust fans, ducts, hoods, separators, and all necessary appurtenances including refuse receptacles shall be so designed, constructed, maintained and operated as to insure the required protection in the production of volume and velocity of exhaust air sufficient to gather dusts, fumes, mists, vapors, or gases from said equipment or process and to convey them 01 501 0167 r.e rruin 249 (ccr.t'd) (2) Is points of safe d spcsol thert*p preventing their dispersion in harmful '.-entities, into the at.mo sphere of work rcor.s, or other places where oersor.s ... -- ^ (3.) Duration of Operation:- The exhaust system shall be in operation continually during nil operations 'which it is designed to serve. If the employee remains in the contaminated zone, the system shall continue to operate for some time after the cessation of said operations, the length of time to depend upon the individual circumstances and effectiveness cf the general ventilation system. (4.) Disposal of Exhaust Materials:- The air outlet from every dust' separator and the fumes, mists, vapors, or gases collected by an exhaust system shall discharge in such a manner that the discharged materials shall not re enter places of employment in harmful qur.ntitic-s or in concentrations which exceed the maximum allowable concentrations specified in Regulation 247. Dust, and refuse discharged from an exhaust system shall be burned (when feasible), buried, treated, or otherwise disposed of in a manner that will prevent its harm ful dispersion. Regulation 25C. (Dust-Allaying Media). Use shall be made of water, oil or chemicals in such non-injurious quantities and with such frequency, as may be necessary to suppress and allay harmful dust wherever the provisions of Regulation 249 are impracticable or inadequate to prevent harmful exposure. The use of dust allaying media may also be supplementary to other provisions of these regulations. Regulation 251. (Fersonnl Protective Equipment). (1.) When to be Worn:- Where the removal of harmful dusts, fumes, mists, vepors or gases at their source, as provided for in Regulation 249 is impracticable the employees who may be liable to harmful exposure shall be protected by means of respiratory or other protective equipment approved by the Ohio Department of Health for the specified employment involved. (2.) Protection of Temporary Nature:- The use of respiratory equipment shall in general, be regarded as emergency protection against occasional and/or relatively brief exposure. (3.) Approval Required:- Respiratory protective equipment including filter, cartridge and supplied-air respirators, hose masks, canister-type gas masks, supplied air-hoods and helmets, and self contained oxygen breathing apparatus shall be of a type approved by the Ohio Department of Health. (4.) Education end Use of Equipment Required:- Employers and employees shall familiarize themselves with the use, sanitary care and limitations of such respiratory equipment as they may have occasion to use. (5.) Provision and Care of Equipment Required:- Duty of Employer and . Employee:- It shall be the duty of the employer to provide end replace when necessary, such respiratory and other personal protective equipment as may be required, and to maintain same in efficient and sanitary condition. 01 501 0168 a rv.laticr. 251 (ccnt'd) (5} It shall be the duty of the employee tc use such equipment provided for him and to exercise due care to maintain same in efficient and sanitary condition. Protective devices and protective clothing shall be worn or used at all times during the period of exposure. (4.) Air Su-ply to Positive Pressure Equipment:- Air supplied to hose masks and positive-pressure air helmets shall be free from'.harmful dusts, fur.es, mists, vapors or gases to the extent that the inhalation of such $ir shall not' constitute harmful exposure as set forth in Regulation 247. The air should, preferably, bo supplied by means of a blower-type fan. Whenever compressed air is usean approved filter shall be inserted in the supply lino to remove any oil, sediment or condensation that it may contain. Such filter shall be maintained in efficient working condition. (7.) Ordinary commercial air filters do not remove carbon monoxide. Hence, wherever the air delivered to respiratory equipment is supplied by a compressor, the compressor intake shall be so located as to prevent contamination of the air by carbon monoxide, and an approved filter for carbon monoxide shall be inserted in the air line whenever necessary. (8.) Air Pressure to be Regulated:- Wherever positive-pressure air respiratory equipment is used, an automatic pressure relief valve shall be install ed in the supply line. The maximum allowable pressure shall be 10 pounds per square inch. This does not apply to self-contained oxygen breathing apparatus. a. The standard of health protection when using positive-pressure air respiratory equipment is the maintenance of positive pressure within the equipment. The minimum of air pressure to be maintained within such equip ment is therefore that which will assure a steady and continuous outward flow of air from within the apparatus. (9.) Sanitation of Respiratory Equipment:- -The employer shall provide an approved means for cleaning and sterlizing all respiratory equipment, and it shall be the duty of the employer to cause such equipment to be maintained in a clean and sterile condition. Respiratory equipment shall not be passed on from one man to another until such equipment is cleaned end sterlized. TThen filter or cartridge type respirators are used, each employee shall have such respirator for his own exclusive use. Respiratory equipment and replacement units shall be stored, when not in use, in approved containers. Regulation 252. (Isolation of Hezcrdous Operations) (1.) In every place of employment where a work or process is carried on, in which, or in connection with which, dusts, fumes, mists, vapors or gases are produced in quantities or concentrations and under conditions which may injure the health of the employees, or where environmental conditions harmful to the health of employees are produced, such operations shall be isolated unless the employer elects to control said harmful exposures under other provisions of these regulations. 01 501 0169 Regulation 252 (ccnt'd) (2.) 7;he never practicable, the Indus', ope n or process sh-11 be i. t ct ivolv d or enclosed tc prevent ful icels cr injurious substsrce s z in ccr.t.'ct with the sk :icr. .itr.ticn and Cleanliness) (1.) reintenar.ee : The interiors, exteriors and environs of build that contribute tc a ham: ul exposure to which these regulations apply sha cleaned and maintained in such condition as will prevent harmful exposure forth in Regulation 247. s b*5 set (2.) Cleaning:- TThen to be Done:- Cleaning shall be done at such time of day or nisht as will cause a minimum of exposure of employees. Employees engaged in cleaning operations and all others who may be exposed shall wear approved respiratory equipment unless such cleaning is done by means of suction apparatus capable of preventing harmful exposure. Regulation 254. (Taming of Health Hazards^ In all places of eir.ployrr.ent where harmful exposures exist from infective agents in materials used, from toxic dusts, fumes, mists, vapors or gases and from heat, radiation, humidity, radioactive material or any other injurious substance or causa, the employer shall call attention to such hazards, and shall periodically instruct all employees regarding the harmful exposures connected with their duties and the best preventive measures end methods to protect themselves therefrom. Regulation 255. (Violation). A violation of any of the provisions of the foregoing regulations, or failure tc comply with any orders made pursuant thereto by the Ohio Department of Health, shall subject the person so violating or failing to comply to the penalties provided by law. Regulation 256. (Interpretation). If any of the foregoing regulations shall be held to be unlawful, such holding shall not affect the validity of any other of the foregoing regulations. 01 501 0170
