(3) Approval Required Respiratory protective equipment including filter, cartridge and suppliedair respirators, hose tasks.canister-type gas masks supolied air-hoods and helmets, and self contained oxygen breathing apparatus shall be cf 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 c: such respiratory equipment as they may have oc casion to use. (5) Provision and Care of Equipment Required. Duty of Employer and Employee- It shall be the duty of the employer to provide anc 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 emoloyee to use such equipment provided for him to exercise due care to maintain same in efficient and sanitary condition. Protective devices or.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 vacors or gases to the extent that the inhalation of suca air snail not constitute harmful exposure as set forth in Regulation 2*7. The air should preferably, oe supplied by means of a olower-tyre fan. Whenever compresses 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. (7) Wherever air is delivered tc respiratory equipment, the intake to the blower-type far., low pressure compressor cr ordinary compressor shall be so located as to prevent harmful contamination cf the air by carton monoxide.

(1) Maintenance- The Interiors, exteriors and environs of buildings that contribute to a harm ful exposure to which these regulations apply shall be cleared ar.d maintained in such cor.diton as will prevent harmful exposure as set forth in Regulation 247 (2) Cleaning When to be Cone Cleaning shall be dcr.e a: such time of day cr night as will cause a minimum of exposure of employees. Employees engaged in cleaning operations and all ethers 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. (Warning of Health Hazards). In all daces of emoloyment where harmful ex posures exist from infective agents ir. materials used, from 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 suen hazards, and shall periodically instruct all emoloyees regarding the harmful exposures connected with their duties anc the best preventive measures and methods to protect themselves therefrom.
