APPENDIX 1
SAFETY SYMBOLS
NOTE: The material in this appendix is an official part of SEMI S1 and was approved by full letter ballot procedures on April 30,
2001 by the North American Regional Standards Committee.
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).
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.
When appropriate, the following symbols should be used.
NOTE A1-1: Some symbols (e.g., laser, biohazard, and radiation) are required by law or regulation in some jurisictions.
