What are ANSI standards?ĪNSI is an independent organization that oversees standards for numerous industries. Each color or combination of colors has its own use case. What are ANSI color codes?ĪNSI color codes are described in the ANSI Z535.1-2001 standard for the identification of potential hazards and safety equipment. This standard has three important elements, including a safety header, images, and the sign legend. What is the ANSI format for safety signs?ĪNSI safety sign formats are based on the ANSI Z535-2011 standard. Other formats may still be compliant depending on OSHA standards. When possible, the sign legend should include the type of hazard, the consequence of not avoiding it, and direction for how to avoid the hazard.ĭirect statements are recommended, as they can help to lessen reaction time for the avoidance of a hazard.Īs ANSI Z535-2011 was incorporated into OSHA guidelines, this format for an environmental or facility safety sign, including headers, symbols, and legends, is OSHA compliant. Sign legends should be concise messages that accurately describe the hazard or policy that the sign is indicating. Learn more about safety symbols on our ANSI Z535 Safety Symbols page. In the frequency range from 100 MHz to 1500 MHz, exposure limits for field strength and power density are also generally based on guidelines recommended by the American National Standards Institute (ANSI) in section 4.1 of 'IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz,' ANSI/IEEE C95.1-1992, Copyright 1992 by the Institute of Electrical and Electronics Engineers, Inc., New York, New York 10017.There are four types of ANSI Z535.3 safety symbols: hazard alert, mandatory action, prohibition, and informational. Copyright NCRP, 1986, Bethesda, Maryland 20814. Further information on evaluating compliance with these limits can be found in the FCC's OST/OET Bulletin Number 65, 'Evaluating Compliance with FCC-Specified Guidelines for Human Exposure to Radiofrequency Radiation.' Note to Introductory Paragraph: These limits are generally based on recommended exposure guidelines published by the National Council on Radiation Protection and Measurements (NCRP) in 'Biological Effects and Exposure Criteria for Radiofrequency Electromagnetic Fields,' NCRP Report No. 1.1307(b), except in the case of portable devices which must be evaluated according to the provisions of 47 C.F.R. The criteria listed in Table 4 must be used to evaluate the environmental impact of human exposure to radiofrequency (RF) radiation as specified in 47 C.F.R.
