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(2.1)

“This standard sets forth requirements for the design, application, and use of safety signs in facilities and in the environment.

 

What are the major differences between OSHA and ANSI Standards?

SIGN HEADER:

• Uses familiar block style headers.

• These headers were used in prior ANSI standards.

• Colors are dictated by hazard signal word


WORDING FORMAT:

• Center Justified in the text area


LETTER FORMAT:

• All capital letters

 

Under OSHA’s November 2013 update, users can now use either the latest American National Standard Institute (ANSI) standard from 2011 (ANSI Z535.1, Z535.2 & Z535.5) or the previous standard from 1967-1968. ANSI Z535 signs include a descriptive header, a legend containing the hazard and a visual pictogram to help convey the safety message.

SIGN HEADER:

• Uses triangle surround exclamation point for personal injury hazards signs

• Common Size on Hazard Level Signal Words

• Colors are dictated by hazard signal word


WORDING FORMAT:

• Left justified in the text area with correct punctuation


LETTER FORMAT:

• Capital and small letters in paragraph form
 

 

 

 

Which Header Should I Choose?

 
     
     

DANGER:

OSHA

ANSI

 


29 CFR1910.145(f)(5)

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.”

 


ANSI Z535.2-2011 (4.11.1)

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

 

WARNING:

OSHA

ANSI

 


29 CFR 1910.145(f)(7)

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.”

 


ANSI Z535.2-2011 (4.11.2)

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

 

CAUTION:

OSHA

ANSI

 


29 CFR 1910.145(f)(6)

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.”


ANSI Z535.2-2011 (4.11.3)

“CAUTION: Indicates a hazardous situation that, if not avoided, could result in minor or moderate injury.”

 

NOTICE:

OSHA

ANSI

 


1910.145(f)(9)

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.

 


ANSI Z535.2-2011 (4.11.4)

“NOTICE: Indicates information considered important but not hazard-related. The safety alert symbol shall not be used with this signal word. For environmental/facility signs, NOTICE is typically the choice of signal word for messages relating to property damage, security, sanitation, and housekeeping rules.

 

OTHER:

OSHA

ANSI


1910.145(f)(9)

“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.

 


ANSI Z535.2-2011 (4.11.5)

“SAFETY INSTRUCTIONS or similar words: Indicates a type of safety sign, or a separate panel on a safety sign, where specific safety-related instructions or procedures are described. More definitive signal words are encouraged, where practical, (e.g. SAFE SHUTDOWN PROCEDURE, SAFETY OPERATING PROCEDURES, BOILER SHUTDOWN PROCEDURE, LOCKOUT PROCEDURE, EMERGENCY SHUTDOWN INSTRUCTIONS). The safety alert symbol shall not be used with this classification of signal word. This signal word may also be used as a heading for a safety instruction panel incorporated into a hazard alerting sign to convey lengthy instructional information. See Sections B3.3.6 and B7.
