🔍 Key Concepts

• Safety Data Sheet (SDS) hazard terminology used to describe severity of health effects • Difference between minor/moderate health effects and life‑threatening or permanently disabling effects • How the word toxicity is commonly graded (e.g., low, moderate, high) in safety documentation

💭 Think About

• Which of these terms would most likely be associated with dangers such as death or permanent disability rather than temporary irritation or mild illness? • On an SDS, would life‑threatening hazards be grouped with words suggesting mild risk or with words suggesting the most serious risk? • Does any option sound like a standard, formal category you’d actually expect to see on a chemical safety sheet?

✅ Before You Answer

• Match the phrase "life‑threatening or seriously disabling" with the option that clearly indicates the highest level of danger. • Eliminate any choices that imply mild or limited effects rather than severe ones. • Ask yourself which term sounds like a real SDS label, and which sound made‑up or unlikely.
