Carbon disulfide is a colorless liquid with an ether-like odor. Its exposure can cause dizziness, headache, anxiety, and vision changes. The level of exposure depends upon the dose, duration, and work being done. Carbon disulfide is used in many industries. It’s used to make rubber, viscose rayon, cellophane, and carbon tetrachloride.
