Committee Scope: This Committee shall have primary responsibility for
documents on fire safety symbols including those for building design plans,
investigation diagrams, maps, and for public fire safety. It shall coordinate its
work with NFPA technical committees and other groups dealing with subjects to
which fire safety symbols apply.
This list represents the membership at the time the Committee was balloted
on the text of this edition. Since that time, changes in the membership may
have occurred. A key to classifications is found at the front of this book.
The Report of the Technical Committee on Fire Safety Symbols is presented
for adoption.
This Report was prepared by the Technical Committee on Fire Safety
Symbols and proposes for adoption, amendments to NFPA 170, Standard for
Fire Safety Symbols, 2002 edition. NFPA 170-2002 is published in Volume
7of the 2003 National Fire Codes and in separate pamphlet form.
The Technical Committee on Fire Safety Symbols has retitled NFPA 170 to
Standard for Fire Safety and Emergency Symbols.
This Report has been submitted to letter ballot of the Technical Committee
on Fire Safety Symbols, which consists of 12 voting members. The results of
the balloting, after circulation of any negative votes, can be found in the report.

Submitter : Karin Rountree , Ampco Safety Tools
Recommendation: Anywhere ignition sources are a concern, please include as
a requirement; Non-Sparking Tools are required where hazardous, combustible
or flammable gases, liquids, dusts, or residues are present.
Substantiation: Ordinary hand tools are usually made of steel and if struck,
scraped, or dropped, can cause sparks which can be disastrous in an explosive
environment. Non-Sparking Tools eliminate this hazard, however, standards
regarding their application are incomplete, inconsistent and in some cases
inaccurate.
We feel prevention is one of the most effective means of ensuring safety. If
we can prevent an accident and save someoneʼs life and business, if we can
implement standards and codes to educate and inform before an accident
happens, then we should make the necessary standards and codes to solve the
problem.
The standards and recommended practices developed by NFPA are designed to
improve overall safety and protection of property and personnel. Implementing
a Non-Sparking Tools requirement wherever an ignition source is a concern
would reduce the risk of fire and explosion where hazardous conditions are
present.
Non-Sparking Tools are recommended by Safety Engineers and Insurance
Companies and meet OSHA and EPA requirements where hazardous,
combustible or flammable gases, liquids, dusts and residues are present. NonSparking Tools should be used when storing, processing, handling hazardous
materials as well as maintenance and repair operations within hazardous
environments. All it takes is just one spark to cause an explosion.

Submitter : Geoffrey Peckham , Hazard Communications
Recommendation: Replace “1991” with “2002” in the reference for the ANSI
Z535.1 Safety Color Code.
Substantiation: 2.3.1 references the 1991 edition of the ANSI Z535.1 Safety
Color Code. This standard, which I have chaired since 1992, was revised in
1998 and again in 2002. This next edition of NFPA 170 should reference the
2002 revision. Note that the next revision of the Z535.1 standard is slated for
2006.
Committee Meeting Action: Accept in Principle
Refer also to ANSI Safety Color Chart in Section 4.1.3.3.

Submitter : Geoffrey Peckham , Hazard Communications / Rep. ANSI 2535
US Tag to ISO/TC 145
Recommendation: Replace the figures that include the referent “Emergency
Exit” with the international ISO accepted symbol for this referent included in
ISO 7010 as symbols E001 and E002.
170-2
Report on Proposals — Copyright, NFPA
Substantiation: The ISO “Emergency Exit” symbol was developed years ago
in Japan and forms the basis for the international acceptance of a single symbol
for this referent. Though they are similar in many respects, the symbol is
highly refined and much better drawn than the figure shown in NFPA 170. I
have included EPS files for these symbols on a CD that accompanies my
proposals so that you may have the highest reproduction quality when printing
this symbol. The ONLY color allowed for this symbol is solid green with a
white door opening. Green is the proper color, according to ISO 3864, for
“Safe Condition” signs - and this referent falls into this category of symbols.
As for its shape in Table 4.2, it should be shown in a square. In practice this
symbol is incorporated into a vertical or horizontal rectangular sign that
incorporates a directional arrow. For this reason, please consider adopting
adding a chart for the use of arrows as described in another of my revision
proposals. The word “EXIT” may also be added to the completed sign.

Submitter : Geoffrey Peckham , Hazard Communications / Rep. ANSI 2535
US Tag to ISO/TC 145
Recommendation: Add a section to Table 4.2 that explains the “Use of
Arrows” to indicate the direction of travel on an egress route. See section 8.6 in
ISO 3864 for an example of how this can be done. (See Table 4.2 on the
following page.
Substantiation: If NFPA 170 just illustrates an arrow symbol, sign
manufacturers and those installing signs will not understand exactly how the
arrows should be used. The “UP” arrow is used for moving “through” a door,
not a “DOWN” arrow. In a stairwell, going “up” is indicated by an arrow that
is pointed up at a 45 degree angle, and so on. I have even seen the “emergency
exit” symbol on a sign with the man pointed in one direction and the arrow
pointed in the other direction. Guidance is needed and examples of use for
putting the components together should be given in this standard.
Committee Meeting Action: Accept in Principle
Accept the signage with description (eight positions) as submitted without the
word “EXIT” and the man symbol in second line of Table 4.2.

(4.2, 5.2)

Submitter : Geoffrey Peckham , Hazard Communications / Rep. ANSI 2535
US Tag to ISO/TC 145
Recommendation: Replace the symbol for “Arrow” with the international
ISO accepted symbol for this referent included in ISO 7010 as symbols E003
and E004 and include examples of the use of directional arrows in Table 4.2 or
in a new annex for directional way-guidance. Delete the “chevron” arrowheads
that appear in the second “Emergency Exit” symbol in table 4.2. The ISO
arrow should also replace the “directional arrow” symbols found Table 5.2 and
the illustrations in the front of the standard.
Substantiation: The arrows that appear in NFPA 170 to indicate direction are
not the same and they should be. Some are close in shape to the arrow with a
Belgian Head that is standardized in ISO 3864 and ISO 7010 and I propose that
NFPA accept the ISO arrow as the standard graphical symbol for a directional
arrow. I have included EPS files for these symbols on a CD that accompanies
my proposals so that you may have the highest reproduction quality when
printing this symbol. The color for the “emergency exit” directional arrow
should ONLY be green on a white background or white on a green background.
The ONLY color for the “fire equipment location” directional arrow should be
white on a red background.
Committee Meeting Action: Accept in Principle
Delete chevrons in Table 4.2 on p.5, change arrows in Table 4.2 on p.6 to
indicate ISO arrows. (See Table 4.2 on following pages.)

NOTE: This Proposal appeared as Comment 170-5 (Log # 3 ) which was
held from the ROC on Proposal 170-19.
Submitter : Vince Baclawski , , and Bill Hopple National Electrical
Manufacturers Association (NEMA) / Rep. NEMA/CAFAA
Recommendation: Change to “Accept in Principle”. Continue to “Accept” the
committee recommendation(s) but delete item (6) Pull Station and its symbol
from Section 5.7.1.1.
Substantiation: We do not believe there is any reason to designate item (6)
from the basic shape of the Manual Station shown in 5.7.1.1. We believe that
“Pull Station” was added because members of the industry often refer to it this
way. However, Chapter 2 of NFPA 72 continues to call it a “Manual Box”. If
this symbol exists for some other reason, then why are there not symbols (and
subscript) for other types of activated manual boxes? We will be submitting a
change next cycle to change the title from “Manual Station” to “Manual Box”
for consistency with NFPA 72. If this comment is considered new material, we
will submit it during the next cycle.
Committee Meeting Action: Accept in Principle
Add to Manual Station-pull station: “Manual-Station - Pull Station / Fire
Alarm Box “ in Table 6.7.1, include the change to Tables 7.3 and 4.2 (pages 8,

Submitter : Technical Committee on Fire Safety and Emergency Symbols
Recommendation: Add a new Chapter 8 Titled “Symbology for Emergency
Management Mapping”, including all symbols from the Homeland Security
Working Group. (See Tables 8.1, 8.2, 8.3, 8.4, and 8.5 on the following pages.
Substantiation: These symbols were prepared by the Federal Graphic Data
Committeeʼs Homeland Security Working Group in support of the preparation
for, prevention of, protection against , response to and recovery from threats to
the nationʼs population centers and critical infrastructure that are of a terrorist,
criminal, accidental, or natural origin and related events.
Use of different symbols for the same information slows and degrades
communication, particularly when many organizations need to coordinate
operations. This set of symbols was compiled to support homeland security
applications with the intent of concentrating efforts on emergency response.
Upon completion of the project, the Homeland Security Working Group
intended to submit the symbols for formal adoption through an accredited
standards organization. The Technical Committee on Fire Safety Symbols has
agreed to adopt and maintain these symbols in NFPA 170 as a result of these
efforts.

Recommendation: The prohibition symbol that is used in this standard in
NOT the ISO proscribed shape for this sign. ISO 3864 gives a clear definition
for the structure of this symbol, with the interior slash at 80% of the width
of the circular bandʼs width, and the bandʼs width is 10% of the width of the
overall circleʼs diameter (see ISO 3864, Fig. 1, section 7).
Substantiation: One uniform shape should be used for the prohibition
symbol. Thinner lines make visibility difficult and thicker lines obscure the
symbol underneath. An EPS graphic of this symbol is included on the CD.
Committee Meeting Action: Accept
Add symbol as proposed.
