Fuel oil is designated with which UN ID number?

Fuel oil is designated with the UN ID number 1993. This number is part of a standardized system used for the identification of hazardous materials during transport. UN 1993 specifically refers to "Flammable liquids, n.o.s." (not otherwise specified), which includes various types of fuel oils among other flammable liquids.

Understanding the significance of the UN ID number in this context is important for ensuring proper handling, storage, and transportation of hazardous materials. Each number corresponds to specific properties and regulations that govern the safe management of the material. Fuel oils can pose fire hazards and must be treated accordingly based on the risk classification indicated by their UN number.

The other options correspond to different substances. For instance, UN 1000 typically refers to "Acetic acid, glacial," while UN 1203 designates "Gasoline." UN 2315 corresponds to "Flammable solids, n.o.s." This knowledge of UN numbers is crucial for emergency response and safety protocol in the fire service.
