🔍 Key Concepts

• flash point vs fire point – how they differ in temperature and what each one means • Meaning of lower explosive limit (LEL) – is it a temperature or a concentration? • What does threshold limit value (TLV) usually refer to in industrial hygiene?

💭 Think About

• Ask yourself: is the question talking about a temperature or a concentration in air? That will immediately rule out some choices. • Which term is defined as the FIRST temperature where enough vapor is produced to ignite briefly if an ignition source is applied, even if it does not keep burning? • Which term refers to the temperature where the substance will continue to burn after ignition, and how is that different from the question’s wording?

✅ Before You Answer

• Verify which terms are measured in degrees (°F/°C) versus those measured as a percentage of vapor in air or exposure limit. • Check the phrase "lowest temperature" and match it to the standard safety definition from fire protection/chemical safety texts. • Confirm which option is used on Material Safety Data Sheets (MSDS/SDS) to describe the ignition characteristics of liquids.
