5.5 safety label — a sign, label, or decal that provides safety information.

5.6 signal word — the word that calls attention to the safety label and designates a degree or level of hazard

seriousness.

5.7 surround shape — a geometric configuration that is placed around a symbol and which conveys additional

safety information.

5.8 symbol — a graphical representation, either abstract or representational, of a hazard, a consequence of engaging

a hazard, or a method to avoid a hazard, or some combination of these ideas.

NOTE 6: Some label design standards use the term “pictorial” in the same sense as this guideline uses the term “symbol.”

5.9 target audience — the audience to be advised of the hazard.

6 General Provisions

6.1 Safety labels should communicate information about specific hazards. Safety labels should be simple, direct,

and understandable by the target audience.

6.2 Content — Safety labels should communicate:

6.2.1 the seriousness of the hazard (indicated by the signal word);

6.2.2 the nature of the hazard (e.g., type of hazard) or the probable consequence of engaging the hazard; and

6.2.3 how the hazard can be avoided.

6.3 See Figure 2 for examples of how this information can be communicated on a safety label.

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.

Examples of Format Options for Product Safety Labels

7.2 Multiple Hazard Formats — More than one hazard may be conveyed on a single safety label (see Figure 4 for

examples).
