Numbers

Spell out numbers one through nine. Use figures for numbers 10 or greater:
Example: one, two, three, four, five, six, seven, eight, nine, 10, 11, 12, 13, 14, 15, etc.
Exceptions: AP Style calls for figures to express percentages, weights and other measures, and some other specialized instances.
AP Style allows for mixing words and figures:
Example: John conducted 12 inspections in March and nine inspections in April.
Do not begin a sentence with a figure. Recast the sentence so the number is not at the beginning or spell out the number.
Exception: 2009 was a good year for OSH inspections.
For enumerated lists, use a period after each numeral in diplayed lists. Place each numeral within parentheses for enumerated lists run into text.

Some Exceptions to AP Style

AP style calls for placing titles of works in quotation marks. Follow the guidelines of Chicago, setting the titles in italics, for books, movies, periodicals and newspapers. Follow Chicago's guidelines for bibliographies, reference lists, footnotes and endnotes.

Do not space dashes. AP Style calls for a space before and after a dash. Including these spaces can cause problems for the page layout software used by Publications.

When typesetting documents, Publications will use true foot and inch marks instead of an apostrophe and a closing quotation mark.

Brackets may be used to indicate an omission or change in quoted material. Follow the guidelines of Chicago when using brackets.

For the sake of consistency, always form the possessive of singular common nouns ending in s by adding an apostrophe and an s:

Strict AP Style: the hostess's party, the hostess' seat
NCDOL Style: the witness's testimony, the witness's statement

En dashes may be used to indicate an inclusive range of numbers:

Example:

pp. 112–14
Oct. 12–14, 2011
