Examples of How Product Safety Labels Communicate Content
(Note that the order and content of the word message is flexible).
6.4 Identifier — Safety labels should have a unique identifier (e.g., a part number) printed on the label, to facilitate
ordering replacement labels from the equipment manufacturer.
NOTE 7: If a safety label becomes illegible, the user may want to replace it.
6.5 Durability — Safety labels should have a reasonable useful life. Determination of reasonable useful life should
take into consideration the expected life of the product and the intended environment of use.
NOTE 8: Two factors that may be used for judging useful life are color stability and legibility when viewed at a safe viewing
distance. Legibility is affected by letter height.
7 Formats
7.1 Safety labels should consist of at least three panels: signal word panel, word message panel, and symbol panel.
Figure 3 provides examples of some possible horizontal and vertical formats incorporating these panels.
EXCEPTION 1: A symbol panel is not necessary for labels that indicate only potential property damage hazards.
EXCEPTION 2: When space limitations exist, such as under guards or on small parts, for safety labels whose target
audience is maintenance or service personnel, symbol-only formats with surround shapes (i.e., no signal word, word
message, or symbol panels; see Figures 7, 8, and 9) may be used. In this case, borders around the surround shapes
should be used. Alternatively, for the same situations, a safety label may be used that has a signal word panel and a
word message panel but does not have a symbol panel.

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).
