iratory sensitizer. Vapors irritate eyes, nose and
throat. Safe handling conditions may be maintained
by keeping vapor concentrations below the OSHA
permissible limit for formaldehyde.
Primary Routes of Entry: None known
Signs and symptoms
of Exposure: Acetic acid produced during cure irritates eyes,
nose throat. May cause moderate corneal injury to
eyes.
Inhalation may may cause difficulty in breathing.
Ingestion may cause vomiting.
Existing Conditions
Aggravated by Exposure: Heart disease amd respiratory disorders.
Methyltriacetoxysilane: Eye, skin, and pulmonary
disorders.
