🔍 Key Concepts

• Material Safety Data Sheet (MSDS)/Safety Data Sheet (SDS) health hazard classifications • Difference between teratogen, mutagen, and other chemical hazard terms • Reproductive vs developmental toxicology terminology

💭 Think About

• Which term refers specifically to substances that can harm an embryo or fetus during pregnancy, even if the mother is the one exposed? • Which option instead refers to agents that change genetic material (DNA) in any cell, not just during pregnancy? • Which choices are actually about physical hazards (like extreme cold or easy ignition) rather than biological reproductive effects?

✅ Before You Answer

• Identify which option is defined as causing developmental abnormalities in the fetus. • Eliminate any terms that primarily describe fire or temperature hazards, not health effects. • Distinguish the term that affects offspring during development from the one that mainly affects genes or chromosomes in general.
