Inhalation of trichloroacetic acid vapour may lead to a sore throat and cause fluid to fill the lungs (pulmonary oedema). Trichloroacetic acid can burn the skin and eyes. Blurred vision and permanent eye damage can occur. Long term exposures may lead to a chronic cough and bronchial pneumonia may also occur. Teeth may erode. Trichloroacetic acid is also corrosive on ingestion.
