Administration / exposure

Route of administration:
inhalation
Vehicle:
other: unchanged (no vehicle)
Details on inhalation exposure:
Substantially saturated vapor was prepared by spreading 50 grams of chemical over 200 cm(2) area on shallow tray placed near the top of a 120-litre glass chamber which was then sealed for at least 16 hours while an intermittently operated fan agitated the internal chamber atmosphere. 
Analytical verification of test atmosphere concentrations:
no
Duration of exposure:
8 h
No. of animals per sex per dose:
6
Control animals:
not specified
Details on study design:
Rats introduced in a gasketed drawer-type cage designed and operated to minimize vapor loss. The study was conducted at 20°C. The animals were observed for 14 days postexposure for signs of toxicity.
Statistics:
Not applicable.

Mortality:
Exposure to substantially saturated vapor for 8 hours caused no mortality.
Clinical signs:
other: No signs and/or symptoms were reported.

Weight change over the 14-day postexposure period ranged from 51 to 71 grams.  

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The findings of a 8-hr exposure to substantially saturated vapour of (3-chloropropyl)trimethoxysilane indicate a low potential for toxicity by acute inhalation exposure.
