• The remaining Chapters 6 through 15 are titled
  and renumbered and are in the same order as they
  are in the 2001 Edition.
• The divisions of the chapters are similar to the
  2001 Edition and include sections with the
  chapter number followed by a number for each
  section in numerical order with a period
  separating the two numbers and a title is
  required.

7
Other Divisions of the Text

• Sections are subdivided into sub-sections and
  have a third number added and generally have a
  title. A title is not required, but if one of the
  sub-sections has a title all of the sib-sections
  in the section must have titles.

8
Other Divisions of the Text

• The next division is a four digit paragraph
  (example- 4.3.2.5) and the next division is a
  sub-paragraph that is identified with a
  parenthetical upper case letter example- (D)
  and this may be followed by a list using
  parenthetical numbers example-(3).

9
Other Divisions of the Text

• If a division of a list is required, it must be a
  parenthetical lower case letter - example - (f)
  - which was used for sub-paragraphs in previous
  editions

10
Lists

• The items in a numbered list should be single
  sentences, single phrases, or single words and
  can follow subsections, paragraphs, or
  sub-paragraphs. The lists are usually preceded by
  text like as follows or the following that
  ends with a colon.

11
Lists

• The listed items should be of parallel
  construction starting with all verbs or all
  nouns. Sub-lists should meet the same criteria
  and are identified with a parenthetical lower
  case letter.

12
Other Interesting Rules

• The term shall be permitted (to be) is used to
  state a use that is permitted or is used to
  indicate an alternative requirement to a
  specified requirement.
• All numbered sections, paragraphs, and listings
  should have at least two divisions.

13
Other Interesting Rules

  be used. Examples of these words are as follows
• Acceptable, Adequate, Appropriate, May,
  Preferred, Substantially, Suitable, Usually, etc.
• Definitions should not contain requirements

14
More Interesting Rules

• Exceptions shall be avoided and previous
  exceptions are now reworded as requirements or
  removed.
• Only one requirement is allowed per paragraph.

15
More Interesting Rules

• The former Appendix is now called the Annex.
• Non-mandatory text for explanation and
  information purposes should be removed from the
  main text and placed in the annexes.

16
More Interesting Rules

• An asterisk is inserted after a section,
  paragraph, or listing number in the text to
  indicate that explanatory material can be found
  in Annex A
• This item is under the same section, paragraph,
  or listing number preceded by the letter A. in
  the Annex.

17
Conclusion

• The Committee reviewed 270 (8-1/2 x 11) pages to
  correct the code to the Manual of Style along
  with many editorial changes to make the code more
  user friendly.
• Many titled subsections were added to make
  finding things much easier.

18
Conclusion

• The Committee reviewed 148 proposals for either
  additions or changes to the code to improve
  safety.
• We feel that the new 2004 Edition of NFPA 58 is
  the most comprehensive and easiest to understand
  code that we have ever had.
