                          SECTION V- HEALTH HAZARD DATA

 
Eye Contact;     Direct contact irritates slightly with redness and
                 swelling. 
Skin Contact;    A single short exposure (less than 24 hours) may
                 irritate. Repeated prolonged contact (24 to 48 
                 hours) may irritate moderately. Product contains
                 oximes which are possible skin sensitizers. 
Inhalation:      Vapor overexposure may cause drowsiness, injure
                 blood, liver and may irritate eyes, nose and throat. 
Oral:            Small amounts transferred to the mouth by fingers
                 during use, etc. should not injure. Swallowing large
                 amounts may injure slightly. 
SPECIAL HEALTH EFFECTS:
            Carcinogens:           None Known.
            Teratogens;            None Known.
            Mutagens:              None Known.
            Reproductive Toxins:   None Known.
SENSITIZERS:
      22984-54-9     1-5%   Methyl Oximino Silane  Possible Skin Sensitizer
      2224-33-1      0-3%   Vinyl Oximino Silane   Possible Skin Sensitizer

Comments: Methyl Ethyl Ketoxime (MEKO) is formed upon contact with water or 
humid air. Male rodents exposed to MEKO vapor throughout their lifetime 
developed live tumors. Since many commonly used chemicals cause liver tumors in 
rats and mice, additional testing is planned by the MEKO supplier to determine 
any relevance to humans. Until more data is known, exposure levels should be 
maintained as low as achievable. 
 
FIRST AID PROCEDURES:
            Eye:   Immediately flush with water for 15 minutes. 
            Skin:  Remove from skin and immediately flush with
                   water for 15 minutes. Get medical attention if
                   irritation or ill effects develop or persist. 
            Inhalation;  Remove to fresh air. Get medical attention if ill
                         effects persist. 
            Oral:   Get medical attention.
Comments; Treat according to person's condition and specifics of exposure.

                   SECTION VII -  PERSONAL PROTECTIVE EQUIPMENT

 
Eye:     Use Proper protection - safety glasses as a minimum. 
Skin:    Wash at mealtime and end of shift. If skin
         contact occurs, change contaminated clothing 
         as soon as possible and thoroughly flush affected
         areas with cool water. Chemical protective gloves
         are recommended. 
Inhalation;   Use respiratory protection unless adequate local
              exhaust ventilation is provided or air sampling 
              data show exposures are within recommended
              exposure guidelines. 
Precautionary Measures:    Avoid eye contact. Avoid skin contact. Avoid
                           breathing vapor. 
 
Comments: Product evolves methyl ethyl ketoxime (MEKO) when exposed to water or
humid air. Provide ventilation during use to control methyl ethyl ketoxime 
(MEKO) within the exposure guidelines (Section II) or use respiratory 
protection. 
 

                     SECTION VIII - SPILL OR LEAK PROCEDURES
