What are the scopes of the standards?

29 CFR 1910.145(a)(1) “These specifications apply to the design, application, and use of signs or symbols (as included in paragraphs (c) through (e) of this section) intended to indicate and, insofar as possible, to define specific hazards of a nature such that failure to designate them may lead to accidental injury to workers or the public, or both, or to property damage. These specifications are intended to cover all safety signs except those designed for streets, highways, railroads, and marine regulations. These specifications do not apply to plant bulletin boards or to safety posters.”

ANSI Z 535.2-2011 (R2017) (2.1) “This standard sets forth requirements for the design, application, and use of safety signs in facilities and in the environment.”

Danger :

29 CFR1910.145(f)(5)

ANSI Z535.2-2007 (4.11.1)


“Danger tags. Danger tags shall be used in major hazard situations where an immediate hazard presents a threat of death or serious injury to employees. Danger tags shall be used only in these situations.”

“DANGER: Indicates a hazardous situation which, if not avoided, will result in death or serious injury. This signal word is to be limited to the most extreme situations.”

Warning:

29 CFR 1910.145(f)(7)

ANSI Z535.2-2007 (4.11.2)


“Warning tags. Warning tags may be used to represent a hazard level between "Caution" and "Danger," instead of the required "Caution" tag, provided that they have a signal word of "Warning," an appropriate major message, and otherwise meet the general tag criteria of paragraph (f)(4) of this section.”

“WARNING: Indicates a hazardous situation which, if not avoided, could result in death or serious injury.”

Caution:

29 CFR 1910.145(f)(6)

ANSI Z535.2-2007 (4.11.3)


“Caution tags. Caution tags shall be used in minor hazard situations where a non-immediate or potential hazard or unsafe practice presents a lesser threat of employee injury. Caution tags shall be used only in these situations.”

“CAUTION: Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury. It may also be used without the safety alert symbol as an alternative to “NOTICE”.”

Notice:

1910.145(f)(9)

ANSI Z535.2-2007 (4.11.4)


“Other tags. Other tags may be used in addition to those required by this paragraph (f), or in other situations where this paragraph (f) does not require tags, provided that they do not detract from the impact or visibility of the signal word and major message of any required tag.

“NOTICE: “NOTICE” is the preferred signal word to address practices not related to personal injury. The safety alert symbol shall not be used with this signal word. As an alternative to “NOTICE”, the word “CAUTION” without the safety alert symbol may be used to indicate a message not related to personal injury.”

Other:

1910.145(f)(9)

ANSI Z535.2-2007 (4.11.5)

“Signs for safety instructions or safety equipment location: Signs used to indicate general instructions relative to safe work practices or indicate the location of safety equipment.”
