Most damage caused to humans and animals by fumigation is a result of inhalation. Victims may experience a sense of nausea and dizziness, fatigue, and a neck rash. More significant exposure can lead to gastrointestinal illnesses, headaches, and trouble breathing, while severe inhalation can lead to fluid-filled lungs, dizziness, and death. Mild symptoms will be relieved with fresh air, while more severe cases may require hospitalization.
