Which statement best describes the readability distance requirement for asbestos warning signs?

• A. Visible from 10 Feet
• B. Visible from 20 Feet
• C. Visible from 30 Feet
• D. Visible from 40 Feet

Answer: (B)

Readability distance indicates how far away a warning sign remains legible, so workers can respond before reaching the hazard. For asbestos warning signs, the sign must be legible from 20 feet away. This ensures someone approaching the area can notice the warning early and take appropriate precautions before entering. Placing signs at entrances and designing them with sufficient size and high contrast helps meet this 20-foot readability standard. Distances like 10, 30, or 40 feet would require different sign sizes or placements, but 20 feet is the established requirement here.
