However, due to the high volatility this route of exposure under the usual workplace conditions is of minor importance.\nGastrointestinal tract\nAn extremely low toxicity of the substance in humans observed in oral animal experiments and after accidental ingestion points to very limited resorption from the digestive tract.",
