What is the minimum font size and style specified for the removal warning on red tags?

• A. At least 10-point boldface
• B. 12-point italic
• C. 8-point regular
• D. 14-point underlined

Answer: (A)

The key idea is legibility of warnings on removal tags. To be effective, the warning message must be easy to read quickly by anyone inspecting a fire sprinkler system, even in less-than-ideal conditions. Requiring a minimum font size and a bold style ensures the text stands out and can be read at a glance, which reduces the chance of overlooking a removal situation.

Using bold at a 10-point size achieves that balance: it’s large enough to be read clearly without making the tag bulky, and bold lettering emphasizes the warning so it catches attention. Italic text tends to be harder to read quickly, a smaller size would reduce visibility, and underlining isn’t a standard feature for such warnings and can make letters harder to distinguish. So the specified combination of at least 10-point boldface best ensures the warning is noticeable and legible.
