What is the primary effect of exposure to mustard gas?

The primary effect of exposure to mustard gas is the development of burns and blisters on the skin and in the respiratory tract. Mustard gas is a chemical warfare agent that acts as a blistering agent. When it comes into contact with skin or mucous membranes, it causes significant irritation and damage, leading to the formation of painful blisters. This action stems from its alkylating properties, which disrupt cellular structures and lead to inflammatory responses.

Inhalation of this chemical can also cause severe respiratory issues and damage to lung tissue. However, the hallmark injuries associated with exposure to mustard gas are the characteristic skin and respiratory tract burns and blisters, which can take time to fully develop, making them a key indicator of such exposure. Understanding the primary effects of chemical agents like mustard gas is crucial for triage and treatment in cases of exposure, focusing initially on wound care and respiratory support.
