Regulation 248. fGeneral Ventilation). Special Requirements: Wherever harmful concentration of dusts, 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 hereinafter 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 247.

(2) General Requirements: Exhaust fans, ducts, hoods, sepa rators. 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 to suitable points of safe disposal thereby preventing their dispersion in harmful quan tities into the atmosphere of work rooms, or other places where persons are employed. (3) Duration of Operation: The exhaust system shall be in operation continually during all operations which it is designed ,t/> serve. If the employee remains in the contaminated zone, the sySt'em shall continue to operate for some time after the cessation of said operations, the length of time to depend upon the individual circum stances and effectiveness of the general ventilation system. *7 01 SOI 01ST i4; Disposal of Exhaust Materials The air outlet from dust separator and the fumes, mists, vapors, or gases collected hv aexhaust system shall discharge in such a manner that the li-charo-ematerials shall not reenter places of employment in harmful ties or in concentrations which exceed the maximum allowable con centrations specified in Regulation 247. Dust, and refuse discharged from an exhaust system shall he burned (when feasible), burned"* treated, or otherwise disposed of in a manner that will prevent :r = harmful dispersion. Regulation 230. (Dust Allaying Media). Use shall be made water, oil or chemicals in such non-injurious quantities and w.:h 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 allaving media may also be supplementary to other provisions of these regulations. Regulation 251. (Personal Protective Equipment). (1) When to be Worn: Where the removal of harmful dustfumes, mists, vapors 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 respiratorv or other protective equipment approved by the Ohio Department of Health for the specified employment involved. (2) Protection of Temporary Nature: The use of respiratorv equipment shall in general, be regarded as emergency protection against occasional and/or relatively brief exposure. (3) Approval Required: Respiratory protective equipment in cluding filter, cartridge and supplied-air respirators, hose masks, can ister-type gas masks, supplied air-hoods and helmets, and self con tained oxygen breathing apparatus shall be of a type approved by the Ohio Department of Health. (4) Education and Use of Equipment Required: Employer? 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 Em ployer and Employee: It shall be the duty of the employer to provide and replace when necessary, such respiratory and other personal pro tective equipment as may be required, and to maintain same in effi cient and sanitary condition. It shall be the duty of the employee to use such equipment pro vided 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.aj all times during the period of exposure (6) Air Supply to Positive Pressure Equipment: Air supplied to hose masks and positive-pressure air helmets shall be free from harmful dusts, fumes, mists, vapors, or gases to the extent that the inhalation of such air shall not constitute harmful exposure as set [8 01 501 0158 menu- of .1 :)!u cr-ry:>e ran. Whenever compressed air > :i~e*l an a: proved :ilter shall be inserted in the supply line to remove any Mil. sediment or condensation that it may contain. Such niter -hail I v maintained in efficient working condition. (J) Wherever air is delivered to respiratory equipment. the intake to the blower-tvpe fan. low pressure compressor <>r ordinary compressor shall be so located as to prevent harmful contamination ri the air by carbon monoxide. Internally lubricated compressors are not recommended for supplying air to respirators and. if internally 1111>r:cated compressors are so used they must be provided with a -uitable temperature regulator to prevent overheating of the com pressors and with a carbon monoxide alarm device to insure adequate earning of exposure to carbon monoxide. (81 Air Pressure to be Regulated: Wherever positive-air respiratory equipment is used, an automatic pressure relief valve shall be installed in the supply line. The maximum allowable pressure shall be 10 pounds per square inch. This does not apply to self-con tained oxygen breathing apparatus. a. The standard of health protection when using positivepressure air respiratory equipment is the maintenance of positive pressure within the equipment. The minimum of air pressure to be maintained within such equipment is therefore that which will assure a steady and continuous outward flow of air from within the apparatus. ".<> Sanitation of Respiratory Equipment: The employer shall provide an approved means for cleaning and sterilizing all respiratory equipment, and it shall be the duty of the employer to cause such equipment to be maintained in a clean and sanitary condition. Re-piratory equipment shall not be passed on from one man to another until such equipment is cleaned and sterilized. When (liter 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 J~-'. Isolation of Hazardous Operations). mi 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 em ployees are produced, -uch operations shall be isolated unless the employer elects to control said harmful exposures under other pro visions of these regulations.i i j i Whenever practicable, the industrial operation or process shall be enectively controlled or enclosed to prevent harmful chem icals or injurious substances from coming in contact with the skin. 19 01 501 0159 Regulation 233. < Sanitation and I'.cannr.e-Iti Maintenance: The interiors, exterior- and ... buildings that contribute to a harmt'ul exposure >. hie1, *''. lations apply shall be cleaned and maintained in -uch null prevent harmful exposure as set forth in Regular:-,:: i_M Cleaning: When to be Done: Cleaning -hah ' ... . such time of dav or night as will cause a minimum r\-. - : emplovees.
