The German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area has evaluated a momentary value for trimethylamine [75‐50‐3]. Critical effect is the irritation of the respiratory epithelia in the nose of rats and a maximum concentration at the workplace (MAK value) of 2 ml/m3 has been set. This value was established by analogy with cyclohexylamine. In addition to the MAK value, a momentary value of 5 ml/m3 for cyclohexylamine has been established which must not be exceeded at any time to prevent from local irritation. Therefore, a momentary value of 5 ml/m3 is also set for N,N‐trimethylamine.
