🔍 Key Concepts

• Petroleum vapors affect the lungs and the central nervous system (brain and nerves) • High concentrations of vapors can displace oxygen in the air you breathe • Think about typical symptoms of asphyxiation (lack of oxygen) rather than injuries to eyes, ears, or stomach

💭 Think About

• Which option best matches what happens when you inhale too much vapor and your body doesn’t get enough oxygen? • Do these vapors usually cause damage to a specific sense (sight or hearing), or do they mainly affect breathing and consciousness? • Which effect is most commonly associated with fume inhalation in confined or poorly ventilated spaces?

✅ Before You Answer

• Eliminate choices that sound more like physical trauma (e.g., something hitting or cutting you) than inhalation effects • Ask: does this option clearly involve breathing problems or oxygen loss? • Pick the choice that fits both loss of consciousness and dangerous lack of oxygen from vapor inhalation
