ANSI Z535.2-2011 i AMERICAN NATIONAL STANDARD Approval of an American National Standard requires verification by ANSI that the
12、 requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial
13、agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in an
14、y respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an i
15、nterpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor
16、whose name appears on the title page of this standard. This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American

37、igns and Colors. The Z535 Committee has the following scope: To develop standards for the design, application, and use of signs, colors, and symbols intended to identify and warn against specific hazards and for other accident prevention purposes. While the basic mission and fundamental purpose of t
38、he ANSI Z535 Committee is to develop, refine, and promote a single, uniform graphic system used for communicating safety and accident prevention information, the Z535 Committee recognizes that this information can also be effectively communicated using other graphic systems. The Z535 Committee creat
39、ed subcommittees to update the Z53 and Z35 standards and to write new standards. To date, the following six standards comprise the ANSI Z535 series: ANSI Z535.1 Safety Colors ANSI Z53.1-1979 was updated and combined into this standard in 1991 ANSI Z535.2 Environmental and Facility Safety Signs ANSI
40、Z35.1-1972 and Z35.4-1972 were updated and combined into this standard in 1991 ANSI Z535.3 Criteria for Safety Symbols new in 1991 ANSI Z535.4 Product Safety Signs and Labels new in 1991 ANSI Z535.5 Safety Tags and Barricade Tapes (for Temporary Hazards) ANSI Z35.2-1974 was updated and combined into
41、 this standard in 1991 ANSI Z535.6 Product Safety Information in Product Manuals, Instructions, and Other Collateral Materials new in 2006 Together, these six standards contain the information needed to specify formats, colors, and symbols for safety signs used in environmental and facility applicat
42、ions, in product and product literature applications, and in temporary safety tag and barricade tape applications. Published separately is the ANSI Z535 Safety Color Chart. This chart gives the user a sample of each of the safety colors: red, orange, yellow, green, blue, purple, brown, grey, white,
43、and black. It also describes each colors ink formulation and closest PANTONE color. This ANSI Z535.2 standard was prepared by Subcommittee Z535.2 on Environmental and Facility Safety Signs. The foreword and all annexes in this standard are considered to be informative and not normative. In the vocab
44、ulary of writing standards, the word “informative” is meant to convey that the information presented is for informational purposes only and is not considered to be mandatory. The body of this standard is “normative,” meaning that this information is considered to be mandatory. This standard was form
45、ulated to provide a visual alerting system to aid in identifying potential hazards known to exist in facilities and in the environment. Together, ANSI Z535.1, Z535.2, and Z535.3 contain information needed to specify formats, colors, and symbols for safety signs used in environmental and facility app
46、lications. The ANSI Z535.4 and Z535.5 standards are harmonized with this standard to provide appropriate hazard avoidance information for products that might be encountered in the environment (ANSI Z535.4) or temporary changes to the environment (ANSI Z535.5). It is desirable that new signs, symbols
47、, and colors for environmental and facility safety signs specified after the approval of this standard comply with this standard. The ANSI Z35 Committee on Safety Signs and ANSI Z53 Committee on Safety Colors were combined in 1979 to form the ANSI Z535 Committee on Safety Signs and Colors. The ANSI
48、Z535.4 standard addresses the design of safety signs and labels for application to products, and was first published in 1991. In that standard, the format specified for the signal word panel was a simple rectangle. The rectangle contained the safety alert symbol and a signal word (DANGER, CAUTION, o
49、r WARNING), and specific safety colors were designated to be used with those signal words (DANGER / Safety Red; ANSI Z535.2-2011 viii WARNING / Safety Orange; CAUTION / Safety Yellow). This contrasted with the longstanding format of the black rectangle with red oval and white letters used for danger signs. The initial impetus for the new ANSI Z535.4-1991 header format was that products often had limited space for a sign or label and omitting the older format allowed for bigger letters for the signal word. The ANSI Z535.2-1991 standard retained the longstanding DANGER heading
