Which feature helps learners identify safety requirements in printed lab manuals?

• A. Rich illustrations
• B. Minimal whitespace
• C. Long paragraphs
• D. Hazard notices

Answer: (D)

In printed lab manuals, safety-critical information must be easy to spot so learners can quickly find the precautions they need before handling materials or equipment. Hazard notices are designed specifically for this purpose. They use clear, concise wording and recognizable cues like bold headings (such as Warning or Caution), standardized symbols, and often color or boxed layouts to stand out from the surrounding text. This makes safety requirements highly visible even when a student is skimming or looking for quick guidance during a task, helping them know exactly what PPE is needed, what procedures to follow, or what to avoid.

Rich illustrations can aid understanding but don’t inherently flag safety steps, while minimal whitespace or long paragraphs can make important safety rules harder to notice or recall. The distinct, attention-grabbing format of hazard notices is what makes them the best feature for identifying safety requirements.
