AMERICAN NATIONAL STANDARD Published by Approval of an American National Standard requires verification by ANSI that the requirements for due pro
12、cess, 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 agreement means much more
13、 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 any respect preclude anyone
14、, 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 interpretation of any Amer
15、ican 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 whose name appears on the
16、 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 This American National Standard may be revised or withdrawn at any time.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 National Standards may r

Figure 1 The Safety Alert Symbol 4.12 safety sign: A visual alerting device in the form of a decal, label, placard, cord tag, or other marking such as an embossing, stamping, etching, or other process that provides safety informati
28、on. 4.12.1 environmental/facility safety sign: Sign or placard in a work or public area that provides safety information. 4.12.2 product safety sign or label: Sign, label, cord tag, or decal affixed to a product that provides safety information about that product. 4.12.2.1 permanent safety sign or l
29、abel: A sign that is to be permanently affixed to the product so that it cannot be easily removed. Permanent safety signs typically provide information about potential exposure to hazards inherent in the normal use associated with the product, or which might be created during other reasonably antici
30、pated product use or misuse. 4.12.2.2 temporary safety sign or tag: A sign affixed to a product or its container that is intended to be removed. Temporary safety signs and tags typically provide information about a temporary hazard created by situations such as shipment, setup, service or repair. 4.
31、12.3 Types of product safety signs 4.12.3.1 hazard alerting sign: Sign directly related to a hazard that identifies the hazard, the level of hazard seriousness, the probable consequence of involvement with the hazard, and how the hazard can be avoided. When information on consequence, avoidance, or
32、type of hazard is readily inferred, this Information may be omitted from the message panel (see Annex 83.1 ). 4.12.3.2 safety notice sign: Sign that gives notice of safety practices not directly related to physical injury. 4.12.3.3 safety instruction sign: Sign that identifies specific safety-relate
33、d i ns1 ructions or procedures. This type of sign may be used to supplement a haxard alerting sign by providing a place to convey lengthy safety-related instructional information. 4.13 safety symbol: A graphic representation intended to convey a safety message without the use of words. (See ANSI Z53
34、5.3) 4.14 signal words: The words used in the signal word panel. The signal words for hazard alerting signs are “DANGER,“ “WARNING, and cAUTION: Safety notice signs use the signal word “NOTICE: Safety instruction signs use signal words that are specific to the situation. See Annex E for guidance in
35、selecting a signal word. 4.14.1 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. 3 ANSI Z535.4-2011 4.14.2 WARNING: Indicates a hazardous situation that, if not avoided, could resul
36、t in death or serious injury. 4.14.3 CAUTION: Indicates a hazardous situation that, if not avoided, could result in minor or moderate injury. 4.14.4 NOTICE: Indicates information considered important, but not hazard-related (e.g., messages relating to property damage). The safety alert symbol shall
37、not be used with this signal word. 4.14.5 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 SHUT
38、DOWN PROCEDURE, SAFE OPERATING PROCEDURES, BOILER SHUTDOWN PROCEDURE, LOCKOUT PROCEDURE, SAFE INSTALLATION INSTRUCTIONS, 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 in
39、struction panel incorporated into a hazard alerting sign to convey lengthy instructional information (see Annex 87). 5 Use of signal words 5.1 Hazard classification Hazard alerting signs are classified according to the relative seriousness of the hazardous situation. The classification is based on t
40、he probability of being injured if the hazard is not avoided, and on the severity of the resulting injury. For hazard alerting signs, there are three hazard classifications that are denoted by the signal words “DANGER,“ “WARNING,“ and “CAUTION.“ 5.2 Signal word selection When no federal, state, or l
41、ocal government code, regulation, standard, or guideline specifies a particular signal word, selection of the signal word shall be made in accordance with the definitions provided in Section 4. 5.3 Multiple hazard signs 5.3.1 One sign or label When more than one hazard exists on a product, either in
42、 close proximity to each other, or which might be preventable from a common location, one hazard alerting sign may be used, provided that the information addresses each hazard. 5.3.2 Signal word for multiple hazard signs When multiple hazardous situations are addressed on one hazard alerting sign, a
43、nd the hazards are classified at different levels of seriousness, the signal word corresponding to the greatest level of seriousness (i.e., DANGER, WARNING, or CAUTION) shall be used. 6 Sign or label format 6.1 Panels A product safety sign or label consists of a signal word panel plus a message pane
44、l. On hazard alerting signs, in addition to a word message, a safety instruction panel may be incorporated as a place to convey lengthy instructional information (see Figure 13). A safety symbol panel may be used to communicate a part or all of the elements of a message panel (see Annex 83.1 ). 6.2
45、Panel arrangement 6.2.1 Panel format The sign or label panels may be in a horizontal or vertical format. See Figures 2 through 13 for examples. 6.2.2 Panel placement The relative placement of the signal word and message panels should be such that the signal word panel precedes all text in the messag
46、e panel, as shown in Figures 2 through 6 and in Figure 10. When space is 4 ANSI Z535.4-2011 limited, a panel arrangement such as that shown in Figures 7, 8, and 11 may be used to increase the size of the message panel. When vertical space, in particular, is limited, the panel arrangement shown in Fi
47、gure 8 may be used. An option for a larger symbol panel is shown in Figure 9. When no word message panel is used, the panel arrangement shown in Figure 12 may be used. Figure 13 is an example of how a safety instructions panel may be incorporated into a hazard alerting sign. 6.2.3 Panel shape Panels
48、 may be non-rectangular to make good use of the available space. 6.3 Safety alert symbol A safety alert symbol, when used with the signal word, shall precede the signal word. The base of the safety alert symbol shall be on the same horizontal line as the base of the letters of the signal word. The h
49、eight of the safety alert symbol shall equal or exceed the signal word letter height. 6.4 Distinctiveness A safety sign or label shall be distinctive on the product. A contrasting border may be used on the sign to achieve distinctiveness. 6.5 Word message The word message should be concise and readily understood. 6.5.1 Multiple messages Multiple messages should be provided with sufficient space between them, when feasible, to prevent them from visually blending together. 6.5.2 Longer word messages and space limitations When detailed instructions, precautions, or consequences re
