4. Descriptions of symbols
4.1 Description of touch symbol
The touch symbol, shown in Figure 3, shows a finger approaching a surface as if ready to touch.When touching is prohibited, the symbol is shown under a circular band with diagonal slash (see Figure 4), consistent with ANSI/NEMAZ535.3-2011.
4.2 Description of the RF electric current hazard advisory symbol
The RF electric current hazard advisory symbol, shown in Figure 1, is the downward pointed lightning bolt now used to warn people about lower frequency shock hazards. This symbol is consistent with ANSI/ NEMAZ535.3-2011.
4.3 Description of the RF energy advisory symbol
The advisory symbol for identifying incident RF energy consists of black wavefronts radiating from a stylized point source antenna and supporting structure, as shown in Figure 2, and is consistent with the general recommendations ofANSI/NEMAZ535.3-2011.
5. Design and use of advisory signs
5.1 Colors
Advisory signs shall comply with the color specifications of ANSI/NEMA Z535.1-2017 and colors shall be used as specified in ANSI/NEMA Z535.2-2011, summarized in 5.2 through 5.8, with examples of when different signs should be used. Text and symbols shall be in colors that contrast strongly against the background color(s).
5.2 Use of symbols
The symbols described in Clause 4 should be used as a part of safety signs and labels that comply with the ANSI/NEMA Z535 series of standards; safety signs that contain only words may be used although the use of symbols is encouraged. The RF electric current hazard advisory and the RF energy advisory symbols, shown in Figure 1 and Figure 2, shall be enclosed in a triangle when used for warning purposes, as shown in Figure 5. The touch symbol in Figure 3 shall be under a circle with bar when used to prohibit actions, as shown in Figure 4. The symbol and triangle shall be black in accordance withANSI/NEMAZ535.2-2011. The apices of the triangles may be rounded.
5.3 Layout of signs
The symbols shall be located in a discrete section of the sign as specified byANSI/NEMAZ535.2- 2011 and as summarized in Figure 6. In 5.4 through 5.8, the design of the signal word portion of signs is specified. Formats A through G in Figure 6 are permissible for “DANGER”, “WARNING”, “CAUTION”, and “NOTICE” signs. Formats H and I are prohibited. ALL formats, including H and I, can be used for general safety signs.
5.4 “DANGER” signs
“DANGER” signs shall be used to indicate an imminently hazardous situation that, if not avoided, will likely result in death or serious injury. The signal word should be limited to the most extreme situations. The background color of a “DANGER” sign is white. The signal word panel of a two- or three-panel sign is white against a red background immediately to the right of a white triangle surrounding a red exclamation point. The signal word can be all upper case. Alternatively, the signal word is white print in a red oval, which is surrounded by a white stripe, and which is centered in a black rectangle (see Figure 7).
5.5 “WARNING” signs
“WARNING” signs shall be used to indicate a potentially hazardous situation that, if not avoided, could result in death or serious injury. The background color of a “WARNING” sign is white if the signal word is displayed against an orange rectangle; otherwise it is orange. The signal word panel of a two- or three-panel sign is black against an orange background immediately to the right of a black triangle surrounding an orange exclamation point. The signal word can be all upper case.Alternatively, the signal word is black print in an orange truncated diamond (hexagon) that is surrounded by a black rectangle (see Figure 8).IEEE C95.2 pdf download.
