Regulation 249- 'Local Exhaust Ventilation) (1) here 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 em ployees exposed thereto, and where general ventilation alone or ir. conjunction with other provisions of these regulations is inadequate to furnish the required protection shall be connected to an ex-r haust system for the removal of said hazards as far as practicable at their point of origin Wher ever practicable application of local exnaust ventilation is preferred (2) General Requirements Exhaust fans ducts hoods separators and all necessary appurte nances including refuse receptacles snail be so designed constructed maintained and operated as to insure the required protection in the production of volume ar.d velocity of exhsusc air sufficient to gather dusts fumes, mists vapors or gases from said equipment cr process and to convey them to suitable ccints of safe disposal thereby oreventir-g their dispersion in harmful quantities into the atmospnere of wcrk rooms or other places where persons are employed (3) Duration cf Operation The exhaust system shall be in operation continually during all operations which it is designed to serve If the employee remains in the contaminated zone the system shall continue to operate for seme time after the cessation of said operations the length of time tc depend upon the ir.aividual circumstances ar.d effectiveness of the general ventilation system (41 Disposal of Exhaust Materials The air outlet frem every dust separator and the fumes mists vapors or gases collected by an exhaust system shall discharge m such a manner that the discharged materials shall not reenter places of employment ir. harmful quantities or in concentra tions which exceed the maximum allowable concentrations specified in Regulation 247 Dust and refuse discharged from an exhaust system shall be burned '.'hen feasible) buried, treated or otherwise disposed cf in a manner that will prevent its harmful dispersion Regulaticr 230 (Dust Allaying .Vedia) Cse 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 ray also be supplementary to other provisions of these regulations Regulation 231 (Personal Protective Equipment) (l) When to be worn Ahere the removal of harmful dusts fumes mists vapors orjgases 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 4 MAT. - 2 1 ' . 9 8 (THU) O M T SAFETY fc HVG1E.VE LIB TEL-614 644 9634 by the Ohio Department of Health for the specified employment involved P.006 (2) Protection of Temporary Nature The use of respiratory equipment shall in general, be re garded as emergency protection against occasional and/or relatively brief exposure. (3) Approval Required Respiratory protective equipment including filter, cartridge and suppliedair respirators., hose tasks.canistsr-tyoe 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 and Use cf Equipment Required Employer? and employees shall familiarize them selves with the use. sanitary care and limitations cf such respiratory equipment as they may have oc casion to use. (5) Provision and Care of Equipment Required: Duty of Employer ar.d 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 efficient and sanitary condition. It shall be the duty of the employee to use such equipment provided for him to exercise due care to maintain same in efficient and sanitary condition. Protective devices ar.d protective clothing shall be worn or used at 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 snail not constitute harmful exposure as sec forth in Regulation 2*7. The air should, preferably, be supplied by means of a blower-type fan. Whenever compressed air is used an approved filter shall be inserted in the supply line to remove any oil, sediment or condensation _ that it may contain. Such filter shall be maintained in efficient working condition. ' (l) Wherever air as delivered tc respiratory equipment, the intake to the blower-type fan, low pressure compressor cr ordinary compressor shall be so located as to prevent harmful contamination of the air by carbon monoxide. Internally lubricated compressors are not recommended for supplying air to respirators ard.. if internally lubricated compressors are sc used they must be provided with a suitable temperature regulator to prevent overheating of the compressors and with a carbon mon oxide alarm device to insure adecuate warning of exposure to carter, monoxide. . (8) Air Pressure to be Regulated Wherever positive-air respiratory equipment is used, an automatic pressure relief valve shall be installed ir. the supply line. The maximum allowable pres* sure shall be 10 peurds cer square inch. This does net apply to self-contained oxygen breathing apparatus. a. The standard of health protection when using positive-pressure air respiratory equip ment is the maintenance of positive pressure within the equipment The minimum of air pres sure to be maintained within such equipment 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 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. Respiratory equipment shall not be passed on from one man to another until such equipment is cleaned and sterilized when filter or cartridge type respirators are used, each employee shall have such respirator for his c*n exclusive use. Respiratory equipment and replacement units shall be stored, when not in use in approved containers Regulation 252- (Isolation of Hazardous Operations). (1) ir. every place of employment where a work cr process is carried on in which, or in con nection ith which dusts fumes, mists, vapors or gases are produced in quantities or concentra tions 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 un less the employer elects to control said harmful exposures under other provisions of these regu lations- 3 Plfll. i i o u n u i u : u f b A h t l l 6; H Y G I E N E L I B TEL: 614 644 9634 P. 007 (2) Whenever practicable, the industrial operation or process shall be effectively controlled or enclosed to prevent harmful chemicals or injurious substances from comine in contact with the skin. Regulation 253- (Sanitation and Cleanliness). (1) Maintenance The interiors, exteriors and environs of buildings that contribute to a harm ful exposure to which these regulations apply shall be cleaned and maintained in sueh conditon as will prevent harmful exposure as set forth in Regulation 24"? (2) Cleaning When to be Cone Cleaning shall be done at such time of day or night as will cause a minimum of exposure of employees- Employees engaged in cleaning operations and ail 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 234. (Warning of Health Hazards). In all olaces of employment where harmful ex posures exist from infective agents in materials used, frcm toxic dusts, fumes, mists, vapors or gases and from heat, radiation, humidity, radioactive material or any other injurious substance or cause, 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 and methods to protect themselves therefrom. Regulation 255. (Violation). A violation of any of the provisions of the foregoing regula tions, or failure to comply with any orders made pursuant thereto by the Ohio Department of Health, shall subject the persons 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 cf any other of the foregoing regulations. 6
