Chlorosilanes containing Si-H bonds can react with HX, forming flammable H2 gas (Arkles, B. 2000. Silicon Compounds, Silanes. In Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. (Online)).
Acids may cause chlorosilanes to decompose, liberating toxic HX and flammable H2 gases (Centre Européen des Silicones (CES), Safe Handling of Chlorosilanes, Chapter VIII, pg. 15. Found at http://www.silicones-safety.eu/files/Chlorosilanes Manual 22082003.pdf).
Inorganic acids may react with chlorosilanes to liberate flammable silane and toxic halogen gases. (Predicted).
Vinyl trichlorosilane is incompatible with strong acids. (Pohanish, Richard P. (2004). HazMat Data - For First Response, Transportation, Storage, and Security (2nd Edition). John Wiley & Sons.)
