58# Protect Your Workers from Heat Stress
## Document Description
A CDC/NIOSH infographic about protecting workers from heat stress, covering acclimatization plans, buddy systems, rest breaks, appropriate clothing, and hydration guidelines.
## Document Characteristics
- Page count: 1
- Content type: Infographic with mixed layout -- icons, illustrations, text blocks, and a data table
- Notable features: Multiple sections with icons/illustrations, color-coded tip boxes, a 4-day exposure schedule table, bold callout text, footer with CDC/NIOSH branding and logos
## What the Conversion Did Well
- Correctly extracted the main title "PROTECT YOUR WORKERS FROM HEAT STRESS"
- Good heading hierarchy: H1 for title, H2 for major sections, H3 for tips
- Accurately captured the acclimatization definition paragraph
- All three tips extracted with correct bold emphasis on key phrases
- The Day 1-4 exposure schedule in Tip 3 is correctly represented as a table
- Buddy system checklist items preserved with checkmarks
- Clothing recommendations (light-colored, breathable, loose-fitting) correctly listed
- Warning about protective equipment increasing heat stress risk is captured
- Hydration guidance ("1 cup every 15 to 20 minutes") is present
- Footer info (CDC URL, department name) correctly extracted
- Some figures have good descriptive alt text (buddy system icon, clothing recommendations)
## What the Conversion Could Improve
- "1 cup every 15 to 20 minutes" is rendered as H1 (line 70) -- this is a callout in the original, not a heading; it should be bold or emphasized text instead
- Many figures have empty alt text (figures 1, 2, 3, 6, 7, 11) -- the infographic has meaningful construction site illustrations, a t-shirt diagram, a building/shade icon, and CDC/NIOSH logos that should be described
- 22 figures were extracted but only 11 are referenced in the markdown -- 11 figures are orphaned
- The reading order places figure-5 (clothing) between the buddy system and rest breaks sections, which does not match the visual layout of the PDF where clothing is in a later section
- The Tip 3 exposure table loses the visual emphasis of the original (large bold percentages with "EXPOSURE" labels underneath each day)
- The "water breaks in shaded or air-conditioned recovery areas" text is fully bolded in the markdown but only partially emphasized in the original
- The CDC laptop/computer icon shown next to the URL in the footer is not described
- The PPE icons (hard hat, gloves, safety vest, boots) shown in the original are not described or referenced in the markdown
