Committee Scope: This Committee shall have primary responsibility for
documents on the design, installation, testing, operation, and maintenance of
systems for the control, removal, or venting of heat or smoke from fires in
buildings.
This list represents the membership at the time the Committee was balloted on
the text of this report. Since that time, changes in the membership may have
occurred. A key to classifications is found at the front of the document.
The Report of the Technical Committee on Smoke Management Systems is
presented for adoption.
This Report was prepared by the Technical Committee on Smoke
Management Systems and proposes for adoption, a complete revision to
NFPA 92A, Recommended Practice for Smoke-Control Systems, 2000 edi-
tion. NFPA 92A is published in Volume 13 of the 2003 National Fire Codes
and in separate pamphlet form.
This Report has been submitted to letter ballot of the Technical Committee
on Smoke Management Systems, which consists of 26 voting members. The
results of the balloting, after circulation of any negative votes, can be found in
the report. 92A-2

Submitter :
Technical Committee on Smoke Management Systems
Recommendation:
Completely revise entire document to comply with the
NFPA Manual of Style as follows:
1. Revise Chapter 1 to contain administrative text only as follows:
(show revised text here or indicate where revised text can be found)
2. Revise Chapter 2 to contain only referenced publications cited in the manda-
tory portions of the document.
3. Revise Chapter 3 to contain only definitions.
4. Appendices are to be restructured and renamed as Annexes.
5. All mandatory sections of the document must be evaluated for usability,
adoptability, and enforceability language. Generate necessary committee pro-
posals as shown (or indicate where shown).
6. Reword exceptions as requirements.
7. Single sentences per requirement as shown (or indicate where shown).
Substantiation:
Editorial restructuring, to conform with the 2000 edition of
the NFPA Manual of Style.
Committee Meeting Action: Accept

Explanation of Abstention:
EVANS: Due to my present obligations, I have not been able to review the
revisions. My apologies.
Comment on Affirmative
BROOKS: Following editorial comments are listed for information only:
1. Section 1.2, sub-items (1) and (2): The phrase smoke refuge area should
replace areas of refuge.
2. Section 1.6: This section is blank? If nothing is inserted, the section number
and title should be deleted.
3. Section 2.1.1: NFPA 72 and NFPA 221 should be listed since they are refer-
enced in Section 6.4.6.2 (and elsewhere) and 6.7.4 (respectively).
4. Section 6.4.3.7: This section refers to Section 6.4.3.7.12.1, I believe the ref-
erence should be to Section 6.4.3.7.13.1.
5. Section 7.1.2.1 (second item in list): A reference is made to Table 2.4.1,
there is no Table 2.4.1.
6. Section 7.1.4.1 (second item on list): A reference is made to Chapter 10, but
there is no Chapter 10.
COMPTON: I would agree with Turnbulls comment that such a major change
as requiring standby power supplies should not be slid into an editorial update
without being properly flagged up. I regard the requirement for standby power
to be a positive step in improving the reliability and effectiveness of pressuriza-
tion systems, although I cannot comment on the risk of less systems being
installed due to the increased cost. Clause 8 is now out of line with the new
requirements in clause 6.7 and needs to be amended to remove the option to
not have standby power systems.
I would also agree with Wolins comment on clause 7. This clause needs
rewriting to reflect the design requirements of 92A, as does A.7.
Table A.5.2.2 needs some editorial amendment. Door width should be (in.) not
(in. w.g.). The door width headings are not in line with the columns below.
HESKESTAD: In A.4.3, first paragraph, sentence in the middle of the para-
graph beginning The doors..., I recommend deletion of the material up to,
and including, the word after the first comma so that the sentence reads This
represents a transient condition that is necessary in order to provide egress
from, or access to, the smoke zone. The material recommended to be deleted
states that the doors are not open for long periods of time, but these time peri-
ods may be long enough to permit significant migration of smoke across the
barrier. I also recommend deletion of the entire second paragraph as not appli-
cable in egress and access situations, where fire growth would not be in a stage
affected significantly by the entering air.
In A.4.6.4, I recommend adding a second sentence to read In other systems,
frequent egress from the smoke zone may cause at least one door to be open
most of the time. This sentence presents the other side of the coin.

Submitter :
Technical Committee on Smoke Management Systems
Recommendation:
1. The Technical Committee on Smoke Management
Systems proposes a complete revision to NFPA 92A, Recommended Practice
for Smoke-Control Systems, as shown at the end of this report.
2. Revise the title of the document to read Standard for Smoke-Control
Systems Utilizing Barriers and Pressure Differences.
Substantiation:
The document was rewritten as a standard to provide manda-
tory information regarding the the design, installation, acceptance testing, oper-
ation and on-going periodic testing of smoke control systems and to provide a
document suitable for both mandatory reference by other standards and codes,
and for adoption into law. As a result of the documents conversion from a rec-
ommended practice to a standard and to comply with NFPAs Manual of Style,
significant format changes and rearrarangeme
