Question 1 of 27070

🔍 Key Concepts

• Material Safety Data Sheet (MSDS) terminology for health effects • Difference between immediate (acute) effects and delayed/repeated-exposure effects • Meaning of the term commonly used for substances that can trigger allergic reactions after multiple exposures

💭 Think About

• Which option specifically refers to an allergic-type response that develops over time with repeated exposure, rather than a one‑time contact? • Look at each choice: which ones describe how a chemical enters the body vs. what kind of reaction it causes? • Think about industrial hygiene terms: what word do safety professionals use for chemicals that can cause allergies, asthma, or rashes after you’ve been exposed several times?

✅ Before You Answer

• Identify which answer choice is a technical term used in MSDS/chemical safety for allergy‑causing agents • Separate routes of exposure (like skin contact or absorption) from the type of health effect • Confirm that the choice you pick matches repeated exposure leading to allergic reaction, not just single‑exposure irritation
