Chemical formula

About Isopentane

Isopentane is a colorless, highly flammable liquid hydrocarbon with a mild gasoline-like odor. It is commonly used as a solvent, a blowing agent in foam manufacturing (e.g., expanded polystyrene), and in refrigeration and cooling systems due to its low boiling point.

Guidance: Extremely flammable vapor can travel and ignite from distant sources. Vapors are heavier than air and can collect in low areas. May cause dizziness or asphyxiation in enclosed spaces. Harmful to aquatic life. Use only with adequate ventilation and keep containers tightly closed.

Always confirm extinguishing agents against the manufacturer SDS and your authority having jurisdiction before specifying a rental building fire-suppression package.
