Question 1 of 27070

A chemical material, as listed on a Material Safety Data Sheet (MSDS) that reacts with water or moist air, and produces a health or physical hazard, is called __________.

🔍 Key Concepts

• Material Safety Data Sheet (MSDS) terminology for specific hazard classes • Difference between a material’s reactivity with water versus its general fire properties (like flammable or combustible) • How hazardous materials that react with water or moist air are categorized in marine and industrial safety

💭 Think About

• Which option directly describes a substance whose main hazard appears only when it contacts water or moist air, rather than just when it’s exposed to a flame or heat source? • Look at the words flammable and combustible: do they say anything about reacting with water, or do they only describe how easily something burns once ignited? • Does the term toxic describe a chemical’s reaction with water, or does it describe the effect on people when they are exposed to the substance?

✅ Before You Answer

• Verify which choice name best matches a material that specifically reacts with water or moist air to create a hazard (not just burns easily). • Check that the correct term is commonly used on MSDS / SDS hazard classifications for substances dangerous when wet. • Eliminate any options that mainly describe how easily a substance burns or how poisonous it is, rather than how it behaves in contact with water.
