Common Hazardous Vapors

Methylene Chloride

Methylene chloride is a colorless liquid with a chloroform-like odor. It is predominantly used as a solvent in paint strippers and removers. The short-term effects of methylene chloride exposure include decreased visual, auditory, and motor functions, but these effects are reversible once exposure ceases.

Methylene chloride targets the eyes, skin, cardiovascular system, and central nervous system in humans.

Benzene

Benzene is a colorless to light-yellow liquid with an aromatic odor. Benzene is found in the air from emissions from burning coal and oil, gasoline service stations, and motor vehicle exhaust. It is found in crude oil, which is often transported in containers on ships.

Benzene can cause irritation in the eyes, skin, nose, and respiratory system. It also commonly causes dizziness, headaches, nausea, and bone marrow depression. Long term exposure is linked to leukemia.

Acrylonitrile

Acrylonitrile is a colorless to pale-yellow liquid with an unpleasant odor. The odor can only be detected when the substance is present above the PEL. Acrylonitrile is primarily used to manufacture acrylic and modacrylic fibers. It is also used as a raw material in the manufacture of plastics.

Exposure symptoms include irritation of the eyes and skin, asphyxia, headache, sneezing, vomiting, weakness, and dizziness. Long-term exposure is linked to brain tumors, lung cancer, and bowel cancer.
