Background Statement for SEMI Draft Document 4316Gdownloads.semi.org/.../$FILE/ATTBFK0O.docx ·...

Background Statement for SEMI Draft Document 5623Line Item Revisions to SEMI S1-0708E, SAFETY GUIDELINE FOR EQUIPMENT SAFETY LABELS Note: This background statement is not part of the balloted item. It is provided solely to assist the recipient in reaching an informed decision based on the rationale of the activity that preceded the creation of this document.

Note: Recipients of this document are invited to submit, with their comments, notification of any relevant patented technology or copyrighted items of which they are aware and to provide supporting documentation. In this context, “patented technology” is defined as technology for which a patent has issued or has been applied for. In the latter case, only publicly available information on the contents of the patent application is to be provided.

Background StatementThis ballot consists of nine (9) line items, the purpose of which is to provide revisions to SEMI S1 in response to negatives received during SEMI S1 5-year review. In the following, ‘TF’ means ‘Task Force.’

Line Item 1: Clarifying the Purpose Statement in Section 1.1 Problem: Section 10 has criteria for the ‘placement’ of safety labels, but Section 1.1 does not include ‘placement’ in the list of topics for which S1 provides guidance.

Solution: The TF proposes to revise Section 1.1 to include ‘placement’ of safety labels.

Line Item 2: Adding “NOTICE” to Note 4 of the Scope Section.Problem: Note 4 references signal words of Danger, Warning and Caution, but did not include Notice.

Solution: The TF proposes to include “Notice” into Note 4 for the sake of completeness.

Line Item 3: Revising Related Information 1 – Letter Height of Text in Message PanelProblem: There are a number of ambiguities in Table R1-1, including the lack of definition of what are “Favorable Reading Conditions” and guidance on how to choose between “Recommended” and “Minimum” Letter Height. This table was originally taken from ANSI Z535.4-2007 and the ANSI Z535.4 Committee acknowledges the ambiguities. Also, there is a reference in Related Information 1 to Annex D of ANSI Z535.4-2007, which should instead be to Annex B.

Solution: The TF proposes to refer to the correct ANSI Z535.4 Annex and simplify the table of letter height and make it clear that the table is intended to be “Recommended Minimum” letter height. Also, since SEMI S8 contains criteria for minimum character height for Display Location, the TF proposes to add reference to SEMI S8 as a useful reference in determining minimum character height for message panels in safety labels. Note: The TF considered deleting Related Information 1 and referencing ANSI Z535.4 for determining letter height of message panels. Based on past industry input and ballot responses, however, the TF believes that the semiconductor industry would rather have a recommended letter height table, even though the content and format are different than that of ANSI Z535.4, than require the reader to reference a separate national standard, such as ANSI Z535.4.This line item has 3 Parts. Part A: Change the title of RI-1 in the Scope sections list in Section 2.2.Part B: Revise Section 10.7 to reference Related Information 1. Part C: Retitle Related Information 1 and modifying the table within it.

Line Item 4: Adding Test Method for Determining “Durability”Problem: SEMI S1 6.5 and SEMI S2 10.2 and SEMI S26 have criteria for labels to be durable and suitable for the use environment, however none of these criteria provides clear guidance or evaluation criteria on how to actually judge label durability.

Solution: The TF proposes to add criteria on how to evaluate label durability in Section 6.5.1, (based on UL 969), and to add a note referencing UL 696 and ISO 17398 for additional guidance on durability. Also, the TF proposes changing “product” to “equipment” in section 6.5 to align with SEMI S2 terminology and the title of SEMI S1.

i

Line Item 5: Addition of NOTICE to Allow for Italics or Non-italicized LettersProblem: The signal word “NOTICE” in the signal word panel in Section Figure 6 shows NOTICE in non-italics/sans serif letters. ANSI Z535.4 specifies NOTICE in italicized sans serif letters.

Solution: The TF proposes to allow NOTICE in either italicized or non-italicized letters. This line item has 2 parts. Part A: Adds an addition Signal Word Panel to Figure 6 showing NOTICE in italicized letters.Part B: Revises Section 11.3.4 to allow “NOTICE” in italicized or non-italicized letters, and adds Note 20 to call attention to the ANSI Z535.4 requirement for NOTICE to be italicized.

Line Item 6: Changing Reference to Appendix 1 from Within Note 12 to a New Section 9.6.Problem 1: In the current version of SEMI S1, the only reference to Appendix 1 occurs in NOTE 12. Since the Appendix (in A1-3) suggests it “should” be used, referencing it from a Note as “preferable” presents an ambiguity as to whether Appendix 1 is or is not normative.

Solution 1: The TF proposes to address this ambiguity by deleting NOTE 12 and inserting the “preferable” reference to Appendix 1 in a new Section 9.6. (Line Item 8 adjusts the Appendix text separately).

Problem 2: The general warning symbol has been removed from ISO 3864-1.

Solution 2: The TF proposes to update Section 9.7 and reference ISO 7010 instead of ISO 3864.

Line Item 7: Adding Tolerance to the Nominal Dimensions for Surround Shapes in Section 9.10Problem: The surround shapes in Figures 8, 9, and 10 contain excessively precise dimensions without tolerances, and so otherwise reasonable label designs might be found to be non-conforming.

Solution: The TF proposes to add a tolerancing statement to Sections 9.10.1.1, 9.10.2.1 and 9.10.3.1.

Line Item 8: Adding New Symbol and Updating Sources in Appendix 1 Problem: The General Warning symbol is no longer in ISO 3864 (the reference currently given). Also the table is missing a general optical radiation symbol (a hazard relevant to many semiconductor industry equipment), and section A1-3 suggests Appendix 1 symbols “should” be used contrary to the main body which suggests they are preferred (see also Line Item 6).

Solution: The TF proposes to modify Appendix 1 to reference ISO 7010 in Section A1-3, update the source of the General Warning symbol (#24), and add a new Optical Radiation symbol (#25), as well as modifying A1-3 to be termed as a preference.

Line Item 9: Correcting the Arabic and Farsi Translations in Table A2-1Problem: Table A2-1 “Translation of Signal Words” contains translation error for Arabic and Farsi.

Solution: The TF proposes to correct the Arabic and Farsi translation errors in Table A2-1.

ii

As part of the 5-year reballot, the TF received a negative asking for the term “Safety Label” to be changed to match the terminology used in SEMI S2 of “hazard alert label”. The TF agrees that alignment of terminology is a good idea, but because of the global nature of such a change in S1 and to simplify this ballot, the TF plans to address that issue in a following ballot.

SEMI S1 currently contains errors in numbering of numerous Figures which were introduced accidentally by SEMI staff when SEMI S1-0708 was editorially revised to SEMI S1-0708E. Most of these errors are shown, unmodified, in this ballot text, and will be corrected later as editorial changes by SEMI Staff, others have been corrected as part of a line item.

If the ballot passes, SEMI Staff will update Section 4 to reflect the addition of new references (e.g., to SEMI S8, ANSI/UL 969, and ISO 17398) as appropriate.

Please forward a courtesy copy of any comments or negatives against the ballot to Edward Karl <[email protected]> and Lauren Crane <[email protected]>. As this is a technical ballot, all votes of reject must be accompanied by reasons (negatives) and be sent to SEMI staff with your vote before the balloting deadline or they will be considered abstention votes.

If you have any comments on the ballot (suggestions or questions that you do not believe are technical negatives), please clearly indicate them as COMMENT to assist us with reducing the administrative overhead in handling them during the task force and committee meetings.

6 General Provisions [Full text versions of sections 6.1 through 6.4 are provided on pages 17 and 18 of this document.]

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 productequipment and the intended environment of use.

NOTE 7: 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.

NOTE 8: Standards such as ANSI/UL 969 and ISO 17398 may serve as useful references for determining durability.

6.5.1 Conformance with the durability criterion for normal use conditions may be demonstrated by inspection after performing the following test. The labels are rubbed by hand, with light pressure, first for 15 seconds with a cloth soaked with the specified cleaning agent (or, if not specified, with water) and then for 15 seconds with a cloth soaked with isopropyl alcohol. The markings should be clearly legible after the above treatment, and adhesive labels should not have worked loose or become curled at the edges.

APPENDIX 1 SAFETY SYMBOLS A1-1 This appendix illustrates symbols used on safety labels for hazards commonly found in the semiconductor manufacturing industry. Additional symbols may need to be developed for other hazards (see ANSI Z535.3, -1998 Informative Annex A for an example of symbol development guidelines).

A1-2 To determine what symbol should be used on a safety label, it is first necessary to determine what message is to be communicated. Symbols may enhance a safety label’s meaning and may be useful to communicate across many languages.

A1-3 When appropriate, the following symbols or symbols from international standards for graphical symbols for safety signs (e.g., ISO 7010) are preferred should be used.

NOTE 1: Some symbols (e.g., laser, biohazard, and radiation) are required by law or regulation in some jurisdictions.

Examples of How Product Safety Labels Communicate Content

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.

6: 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.

7: 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

8 Signal Words8.1 The signal words for safety labels are DANGER, WARNING, CAUTION, and NOTICE.

8.1.1 DANGER is the signal word used to indicate a hazardous situation that, if not avoided, will result in death or severe injury. This signal word is to be limited to the most extreme situations.

8.1.2 WARNING is the signal word used to indicate a hazardous situation that, if not avoided, could result in death or severe injury.

8.1.3 CAUTION is the signal word used to indicate a hazardous situation that, if not avoided, could result in moderate or minor injury. It may be used without the safety alert symbol as an alternative to NOTICE.

8.1.4 NOTICE is the signal word used to indicate a hazardous situation that, if not avoided, could result in property damage. The safety alert symbol should not be used with this signal word. As an alternative to NOTICE, the word CAUTION without the safety alert symbol may be used.

8: SEMI S10 contains examples of ways to categorize severe, moderate, and minor injuries.

8.2 The signal word is placed in the signal word panel.

8.2.1 For DANGER, WARNING, and CAUTION signal words, the safety alert symbol (see Figure 1) is located immediately to the left of and on the same level as the signal word (see Figure 6).

Figure 5Signal Word Panels5

8.2.2 The safety alert symbol should not be used to alert persons to property-damage-only hazards (see Figure 7).

9: The term “property-damage-only” is used in order to align with ANSI Z535.4. “Property-damage-only” is used therein to refer to damage excluding personal injury.

Figure 6Signal Word Panels for Property-Damage-Only Hazards

8.2.3 When multiple hazard situations are addressed on one safety label, and the hazards are classified at different levels of seriousness, the signal word corresponding to the greatest hazard level should be used.

8.3 Translation of the signal words is optional. If the signal word is translated to a language in Appendix 2, the translation in Appendix 2 should be used. If the signal word is translated, the word message should also be translated in the same language as the signal word.

9 Symbols9.1 Symbols are graphic representations chosen to convey specific safety messages.

9.2 The symbol panel should contain the safety label’s symbol(s).

9.2.1 More than one symbol panel may be used on a safety label.

10: See also § 7.2.

9.2.2 More than one symbol may be used in each symbol panel.

9.3 Symbols may be used to clarify or supplement a portion of a safety label’s word message.

11: In some cases, symbols may replace the word message. See the exception to § 10.2.

9.4 A symbol should represent one or more of the following:

the nature of the hazard. the potential consequence of engaging the hazard. actions to be taken to avoid the hazard. actions that are prohibited to avoid the hazard.

9.5 Symbols should be compatible with the safety label’s word message.

12: It is preferable to use the symbols shown in Appendix 1.

13: For additional information on symbol design, see Annex A of ANSI Z535.3.

9.6 Symbols should be shown in their appropriate surround shape as defined in § 9.10.

9.7 When an effective symbol does not exist or cannot be created to illustrate the specific hazard or specific avoidance information, the ISO 3864 general warning symbol should be used with a text message that conveys specific information about the hazard (see Figure 8).

Figure 7Safety Label with General Warning Symbol

9.8 Location — Symbols should be located on safety labels in the areas designated in the examples in Figures 2, 4, and 5, or located in a similar manner. If multiple symbols are used on a multi-hazard safety label, the symbols should appear in the same order as the safety information described in the word message.

EXCEPTION: Location of the safety alert symbol is governed by § 8.2.1.

9.9 Safety Alert Symbol — The safety alert symbol is composed of an equilateral triangle surrounding an exclamation mark.

14: See Figures 1 and 6, and § 11.3.4 for format and color information.

9.10 Symbol Surround Shapes — Safety symbols should be shown in their appropriate surround shapes (see Figures 9, 10, and 11).

15: This is for purposes of international harmonization. The surround shapes have been taken from ISO 3864.

9.10.1 Hazard Identification Surround Shape (see Figure 9) — A symbol located inside a hazard identification surround shape should be used to indicate a personal injury hazard.

9.10.1.1 Format and Color — The background color should be yellow. The triangular band should be black. The symbol or pictorial representing the hazard should be black.

10 Word Message10.1 The word message is placed in the word message panel.

10.2 The word message preferably contains a description of the hazard, the consequence of engaging the hazard, and how to avoid the hazard. The ordering of this content in the word message is flexible.

EXCEPTION: Parts or all of the word message may be omitted, depending on such factors as whether the message can be inferred from a symbol, other text messages, user training, or the context in which the safety label is used.

10.3 The word message on a safety label should be concise and readily understood.

10.4 Messages on the same safety label that warn of different hazards should be formatted, when feasible, to prevent them from visually blending together. Bullets, lines, and extra line spacing are examples of such formatting.

10.5 When detailed instructions, precautions, or consequences would require a lengthy message, the message may alternatively refer the reader to another source for additional safety information. Examples of such sources include safety instructions, operation and maintenance manuals, service manuals, operating procedures, and safety bulletins.

10.6 For languages using the “Roman” alphabet, such as the official languages used in the Americas and in much of the European Union, the lettering of the word message should be a combination of upper- and lowercase sans serif letters. Uppercase only lettering may be used for short messages or for emphasis of individual words.

16: Preferred Roman Sans Serif lettering styles include those named Arial, Arial Bold, Folio Medium, Franklin Gothic, Helvetica, Helvetica Bold, and Univers.

10.7 Lettering should be of a size that enables a person with normal vision, including corrected vision, to read the safety label at a safe viewing distance from the hazard.

17: Related Information 1 provides an example of a method of calculating minimum letter heights.

18: The proportions and spacing of individual letters also affect readability.

11 Colors11.1 Color Specifications — Colors should conform to those colors specified in ISO 3864.

19: For purposes of reproduction, the closest PANTONE color match for opaque safety colors is:

Red – PANTONE 485 Orange – PANTONE 152 Yellow – PANTONE 109 Blue – PANTONE 2945

(PANTONE is a registered trademark of Pantone, Inc.)

20: Perceived color will be different under colored light (e.g., “yellow room”) conditions. The committee knows of no current technical solution.

11.2 Symbol and Surround Shape Color Specifications — See § 9.10 for symbol and surround shape color criteria.
