8 Signal Words

8.1 The signal words for safety labels are DANGER, WARNING, and CAUTION.

8.1.1 DANGER is the signal word used to indicate an imminently hazardous situation that, if not avoided, will

result in death or severe injury. This signal word is to be limited to the most extreme situations.

8.1.2 WARNING is the signal word used to indicate a potentially hazardous situation which, if not avoided, could

result in death or severe injury.

8.1.3 CAUTION is the signal word used to indicate a potentially hazardous situation which, if not avoided, could

result in moderate or minor injury. It may also be used to alert against unsafe practices.

NOTE 9: CAUTION without the safety alert symbol may be used as a signal word to indicate a potentially hazardous situation

which, if not avoided, could result in property damage.

NOTE 10: SEMI S10 contains examples of ways to categorize severe, moderate, and minor injuries.

8.2 The signal word is placed in the signal word panel.

8.2.1 For DANGER, WARNING, and CAUTION signal words, the safety alert symbol (see Figure 1) is located

immediately to the left of and on the same level as the signal word (see Figure 5).

8.2.2 The safety alert symbol should not be used to alert persons to property-damage-only hazards.

8.2.3 When multiple hazard situations are addressed on one safety label, and the hazards are classified at different

levels of seriousness, the signal word corresponding to the greatest hazard level should be used.

9 Symbols

9.1 Symbols are graphic representations chosen to convey specific safety messages.

9.2 The symbol panel should contain the safety label’s symbol(s).

9.2.1 More than one symbol panel may be used on a safety label.

NOTE 11: See also Section 7.2.

9.2.2 More than one symbol may be used in each symbol panel.

9.3 Symbols may be used to clarify or supplement a portion of a safety label’s word message.

NOTE 12: In some cases, symbols may replace the word message. See the exception to Section 10.2.

9.4 A symbol should represent the nature of the hazard, or the potential consequence of engaging the hazard, or

actions to be taken to avoid the hazard.

9.5 Symbols should be compatible with the safety label’s word message.

NOTE 13: It is preferable to use the symbols shown in Appendix 1.

NOTE 14: For additional information on symbol design, see Annex A of ANSI Z535.3.

9.6 Symbols should be shown in their appropriate surround shape as defined in Section 9.10.

9.7 When an effective symbol does not exist or cannot be created to illustrate the specific hazard or specific

avoidance information, the ISO 3864 general warning symbol should be used with a text message that conveys

specific information about the hazard (see Figure 6).

9.8 Location — Symbols should be located on safety labels in the areas designated in the examples in Figures 2, 3,

and 4, or located in a similar manner. If multiple symbols are used on a multi-hazard safety label, the symbols

should appear in the same order as the safety information described in the word message.

EXCEPTION: Location of the safety alert symbol is governed by section 8.2.1.

9.9 Safety Alert Symbol — The safety alert symbol is composed of an equilateral triangle surrounding an

exclamation mark.

NOTE 15: See Figures 1 and 5 and Section 12.3.4 for format and color information.

9.10 Symbol Surround Shapes — Safety symbols should be shown in their appropriate surround shapes (see Figures

7, 8, and 9).

NOTE 16: This is for purposes of international harmonization. The surround shapes have been taken from ISO 3864 and IEC

61310-1.

9.10.1 Hazard Identification Surround Shape (see Figure 7) — A symbol located inside a hazard identification

surround shape should be used to indicate a personal injury hazard.

9.10.1.1 Format and Color — The background color should be yellow. The triangular band should be black. The

symbol or pictorial representing the hazard should be black. The border should be yellow; the border is optional if

the surrounding background is yellow or white. See Figure 7 for more information.

9.10.2 Prohibition Surround Shape (see Figure 8) — A symbol located inside a prohibition surround shape should

be used to indicate that an action should not be taken or should be stopped.

9.10.2.1 Format and Color — The prohibition surround shape should be a circular band with a diagonal bar. The

background color should be white. The circular band and diagonal bar should be red. The symbol representing the

prohibited action should be black and is preferably shown behind the red slash. The border should be white; the

border is optional if the surrounding background is white or yellow. See Figure 8 for more information.
