Flammable Liquid is defined as a substance that catches fire easily with a flash point less than 100F.

Flammable Liquid is defined as a substance that catches fire easily with a flash point less than 100F.

• A. Flammable Liquid
• B. Acute Exposure
• C. Non-threshold
• D. Rate of Entry

Answer: (B)

The main idea is how liquids are classified by how easily their vapors ignite, using the flash point. The flash point is the lowest temperature at which enough vapor can form an ignitable mixture with air to ignite if there’s a spark or flame present. When that temperature is below 100°F, the liquid is considered flammable. If the flash point is at or above 100°F (but below higher thresholds), it’s usually labeled combustible. So the statement describes a flammable liquid. The other concepts are not about ignition risk: acute exposure is about the health effects from short-term contact with a chemical, non-threshold relates to risk assumptions for certain hazards (often carcinogens) where any exposure is considered risky, and rate of entry refers to how a substance enters the body (inhalation, dermal, ingestion).
