Exposure to MITC (methyl isothiocyanate) can indeed trigger asthma attacks in individuals who are susceptible to respiratory issues. MITC is a volatile organic compound commonly used in agricultural applications, particularly in soil fumigation for pest control.

Inhaling or coming into contact with MITC can cause irritation of the respiratory system, which is particularly dangerous for people with pre-existing conditions like asthma. This compound can act as a respiratory irritant and lead to inflammation in the airways, resulting in the hallmark symptoms of an asthma attack such as wheezing, shortness of breath, and chest tightness.

While severe headaches, skin rashes, and sleep disturbances can be associated with various chemicals or environmental factors, they are not the primary health concern linked specifically to MITC exposure. The most immediate risk involves the respiratory system, making asthma attacks in sensitive individuals the most relevant outcome. Understanding these effects is crucial for implementing appropriate safety measures when handling fumigants that may release MITC.
