Question 1 of 27070

🔍 Key Concepts

• Material Safety Data Sheet (MSDS) hazard terminology • Difference between flammable, explosive, and spontaneously combustible materials • Temperature condition: below 130°F (55.5°C) with no external ignition source

💭 Think About

• Which term specifically describes a substance that can ignite just by contact with air, without a spark, flame, or heat source? • How is a material that burns easily when exposed to a flame different from one that can start burning on its own at normal temperatures? • Think about which option is commonly used in chemical safety data to describe spontaneously combustible materials.

✅ Before You Answer

• Verify which term in the choices is used in MSDS to describe spontaneous ignition in air at low temperatures. • Check that the correct term does not require a separate ignition source like a spark or flame. • Eliminate options that mainly refer to explosion risk or general ease of burning rather than self-ignition.
