Re: What cleaner to use for preparing for TT

This is a second link - it opens up for me fine: 

Common Name:    Isopropyl Alcohol 
 CAS Number:     67-63-0 
 DOT Number:     UN 1219 
 Date:           September, 1988 
 ----------------------------------------- 
 
 HAZARD SUMMARY 
 *    Isopropyl Alcohol can affect you when breathed in and by 
      passing through your skin. 
 *    There is an increased risk of cancer associated with the 
      manufacturing of Isopropyl Alcohol. 
 *    Exposure can cause irritation of the eyes, nose, mouth, and 
      throat. 
 *    Overexposure may cause headaches, drowsiness, clumsiness, 
      unconsciousness, and death. 
 *    Contact may irritate the skin. Repeated skin exposure can 
      cause itching, a rash, and drying and cracking. 
 *    Isopropyl Alcohol is a FLAMMABLE LIQUID and a FIRE HAZARD. 
 
 IDENTIFICATION 
 Isopropyl Alcohol is a colorless liquid. Rubbing alcohol is a 
 solution of Isopropyl Alcohol. It is used as a solvent and in 
 making many commercial products. 
 
 REASON FOR CITATION 
 *    Isopropyl Alcohol is on the Hazardous Substance List because 
      it is regulated by OSHA and cited by ACGIH, DOT, NFPA and EPA. 
 *    This chemical is on the Special Health Hazard Substance List 
      because it is FLAMMABLE. 
 *    Definitions are attached. 
 
 HOW TO DETERMINE IF YOU ARE BEING EXPOSED 
 *    Exposure to hazardous substances should be routinely 
      evaluated. This may include collecting air samples. Under OSHA 
      1910.20, you have a legal right to obtain copies of sampling 
      results from your employer. If you think you are experiencing 
      any work related health problems, see a doctor trained to 
      recognize occupational diseases. Take this Fact Sheet with 
      you. 
 *    ODOR THRESHOLD = 22 ppm. 
 *    The odor threshold only serves as a warning of exposure. Not 
      smelling it does not mean you are not being exposed. 
 
 WORKPLACE EXPOSURE LIMITS 
 OSHA:     The legal airborne permissible exposure limit (PEL) is 
           400 ppm averaged over an 8 hour workshift.  
 NIOSH:     The recommended airborne exposure limit is 400 ppm 
           averaged over a 10 hour workshift and 800 ppm, not to be 
           exceeded during any 15 minute work period.  
 ACGIH:    The recommended airborne exposure limit is 400 ppm 
           averaged over an 8 hour workshift and 500 ppm as a STEL 
           (short term exposure limit). 
 
 *    The above exposure limits are for air levels only. When skin 
      contact also occurs, you may be overexposed, even though air 
      levels are less than the limits listed above. 
 
 WAYS OF REDUCING EXPOSURE 
 *    Where possible, enclose operations and use local exhaust 
      ventilation at the site of chemical release. If local exhaust 
      ventilation or enclosure is not used, respirators should be 
      worn. 
 *    Wear protective work clothing. 
 *    Wash thoroughly immediately after exposure to Isopropyl 
      Alcohol and at the end of the workshift. 
 *    Post hazard and warning information in the work area. In 
      addition, as part of an ongoing education and training effort, 
      communicate all information on the health and safety hazards 
      of Isopropyl Alcohol to potentially exposed workers. 
 
 This Fact Sheet is a summary source of information of all potential 
 and most severe health hazards that may result from exposure. 
 Duration of exposure, concentration of the substance and other 
 factors will affect your susceptibility to any of the potential 
 effects described below. 
 ------------------------------------------ 
 
 HEALTH HAZARD INFORMATION 
 
 Acute Health Effects 
 The following acute (short term) health effects may occur 
 immediately or shortly after exposure to Isopropyl Alcohol: 
 
 *    It may irritate the skin, causing a rash or burning feeling on 
      contact. 
 *    Exposure can irritate the eyes, nose, and throat. 
 *    Overexposure to the vapor may cause headaches, drowsiness, a 
      loss of coordination, collapse, and death. 
 
 Chronic Health Effects 
 The following chronic (long term) health effects can occur at some 
 time after exposure to Isopropyl Alcohol and can last for months or 
 years: 
 
 Cancer Hazard 
 *    There is an increased incidence of nasal sinus cancer in 
      workers involved in the manufacture of Isopropyl Alcohol by 
      the strong acid process. There is no evidence that Isopropyl 
      Alcohol is a carcinogen. 
 
 Reproductive Hazard 
 *    According to the information presently available to the New 
      Jersey Department of Health, Isopropyl Alcohol has not been 
      tested for its ability to adversely affect reproduction. 
 
 Other Long Term Effects 
 *    Skin exposure can cause itching, redness, and rashes in some 
      people. Repeated or prolonged exposure can cause dryness and 
      cracking of skin. 
 *    This chemical has not been adequately evaluated to determine 
      whether brain or other nerve damage could occur with repeated 
      exposure. However, many solvents and other petroleum based 
      chemicals have been shown to cause such damage.  Effects may 
      include reduced memory and concentration, personality  changes  
      (withdrawal, irritability), fatigue, sleep disturbances, 
      reduced coordination, and/or effects on nerves supplying 
      internal organs (autonomic nerves) and/or nerves to the arms 
      and legs (weakness, "pins and needles"). 
 
 MEDICAL TESTING 
 
 *    There is no special test for this chemical. However, if 
      illness occurs or overexposure is suspected, medical attention 
      is recommended. 
 *    Interview for brain effects, including recent memory, mood 
      (irritability, withdrawal), concentration, headaches, malaise 
      and altered sleep patterns. Consider cerebellar, autonomic and 
      peripheral nervous system evaluation. Positive and borderline 
      individuals should be referred for neuropsychological testing.
