IT IS ALSO PROBABLE THAT AN EXTREMELY LOW-CARBOHYDRATE DIET (t.e. STILLMAN'S , ETC.) WHICH INDUCES A STATE OF "KETOSIS" WILL POTENTIATE LIVER DAMAGE DUE TO TET OR BETA-TRI OVEREXPOSURE. CARBON TET CAN BE ABSORBED THROUGH THE SKIN IN QUANTITIES GREAT ENOUGH TO CAUSE DAMANGE TO THE LIVER. IT PASSES THROUGH THE SKIN BY DIFFUSION IN THE MOISTURE IN THE SKIN. SKIN NORMALLY CONTAINS ABOUT 90 TIMES AS MUCH WATER AS DRY TISSUE. THIS MUCH WATER INCREASES THE PERMEABILITY OF THE SKIN APPROXIMATELY TENFOLD OVER THAT WHEN IT IS PERFECTLY DRY. UPON ADDITIONAL CONTACT WITH WATER, THE SKIN CAN INCREASE ITS WEIGHT OF WATER 3 TO 5 TIMES, WHICH RESULTS IN AN ADDITIONAL 2 TO 3-FOLD INCREASE IN PERMEABILITY.

These effects apply to stated material and may not apply to dilutions or formulations of that material. SUBCHRONIC EFFECTS - ACUTE/SUBCHRONIC EFFECTS: - Brief exposure (minutes) to high noise levels may cause - ringing in the ears and temporary hearing loss. - Noise-induced hearing loss should be restored within 16 - hours if it is temporary. - Single brief exposure to very loud noise may damage the - eardrum or middle ear bones resulting in permanent - hearing loss. - Prolonged or repeated exposure to noise may cause permanent hearing loss du todamage to the inner ear. Symptoms of excessive exposure to noise may also Include dizziness, nausea, and an increased tendency to be startled by stimuli. * TRADEMARK OF THE DOW CHEMICAL COMPANY RESTRICTED - DOW USE ONLY DO 016468 CONFIDENTIAL |C NSEQUENCES OF EXPOSUHETO TOXIC AMOUNTSf NOISE ACUTE: Short oxposuro to high nolso tarals may causa ringing In tha at* ancuor; temporary hearing lose. Potential for damage Increases aa aound pressure levels Increase above 901 dBA. Repeated short-term exposures may cause permanent loss.

As noise levels increase above 90 dBA, the amount of time required to cause destruction of the sensitive hair cells of the inner ear (cochlea) decreases. This is believed to occur via a metabolic mode in which the hair cells fatigue from lack of oxygen and/or build-up of waste products. Initially, the hair cells of the inner ear can recover from noise trauma if given a sufficient time between insults. This loss is termed a temporary threshold shift or TTS. Upon repeated or prolonged exposures, the cells do not recover and may result in a permanent standard threshold shift Hearing loss is permanent because hair cells do not grow back. Sound pressure levels at or above 115 dBA (8-hr day) may exceed the elastic limit of the normal hearing mechanisms and result in acoustical trauma (hearing ioss due to mechanical damage to the hearing mechanism). A single exposure to loud noise, typically above 140 dBA (explosive noise) can result in hearing loss due to perforation of the eardrum or disruption of the middle ear bones. Chronic: Repeated exposures may cause progressive destruction of hair cells which transmit sound signals to the brain and result in permanent hearing loss (permanent standard threshold shift). Data compiled by ISO, EPA and NIOSH indicated that the risk of material impairment after a working lifetime at 80 dBA ranged from 0 - 5%. Risk of material impairment at 85 dBA and 90 dBA were 10-15% and 21-29% respectively. This data is based on exposure to continuous noise levels without benefit of rest periods (quieter noise periods) or hearing protection. With age, there is some natural hearing loss which is taken int account when a person receives an audiometric exam. DO 01.6469 CONFIDENTIAL CONSEQUENCES OP EXP SURE TO TOXIC AMOUNTS NOISE EXPOSURE GUIDELINES: OSHA PEL a 00 dBA TWA for 8-hour exposure; no continuous exposures above 115 dBA. TWA of 85 dBA or above requires hearing conservation program. DOWIHQ - No exposures above 90 dBA for any exposure period. If 8-hour TWA a 85 dBA or more, employee must: Receive baseline & annual audlometrle exam to identify early hearing tosses and prevent more savers ones. Receive annual training on the effects of noise, and proper use of hearing protectors. Wear hearing protectors If audlometrlo exam shows a standard threshold shift (STS) STS a an average toss of 10 dB at speech frequencies of 2000, 3000 snd 4000 Hz In sitter oar. HEARING PROTECTORS: ear plugs and muffs. Should reduce noise to below 85 dBA. Required for any exposures above 90 dBA. Both muffs and plugs may Irerequired If levels are above 100 dBA. Proper seal Is critical to give maximum protection. HEARING CONSERVATION PROGRAM REQUIREMENTS & PRECAUTIONS The hearing conservation program requirements and exposure precautions are based on the follow exposure categories: LOW-TWA <85 dBA MOD - TWA 85-90 dBA HIGH-TWA >90 dBA EVALUATION OF NOISE EXPOSURES: LOW: Area noise monitoring is recommended a minimum of every three years. Representative exposure monitoring Is not required ad long as the initial exposure estimates indicate that no employee has the potential to exceed a TWA of 85 dBA. MOD: Representative exposure measurements are to be obtained when initial information indicates that an employee's TWA may equal of exceed 85 dBA, or there is a potential for exposure to noise levels > 90 dBA. HIGH; ^apresentathre exposure measurements are to be obtained when Initial information indicate nat an employee's TWA may equal or exceed 85 dBA or there Is potential for exposui o noise levels > 90 dBA. All Expi ore Categories: Monitoring shall will be repeated (optimally every 3 months) whenever a change In production, process, equipment orcontrols may result In new r additional exposures at or above the 8-hr TWA of 85 dBA, or may result In exposures > 90 dBA. PERSONAL HEARING PROTECTION: LOW: No hearing protection required. MOD: Hearing protectors shall be made available to all employees exposed to an 8-hr TWA of 85 dBA or more. Employees with a Standard Threshold Shift and an 8-hr TWA of 85 dBA or more must wear hearing protectors. Hearing protectors must be worn when noise exposures exceed 90 dBA regardless of exposure time. HIGH: Hearing protectors shall be made available to all employees exposed to an 8-hr TWA of 85 dBA or more. Employees with a Standard Threshold Shift and an 8-hour TWA of 85 dBA or more must wear hearing protectors. Hearing protectors must be worn when n ise exposures exceed 90 dBA regardless of exposure time. For noise levels in excess f 105 dBA, a combination of both earplugs & muffs ar rec mm nded.
