ISO Symbols for Safety Signs and Labels

ISO Standards for Safety Signage

This section provides an overview of ISO standards for safety signage, including graphical symbols, sign formats, colors, and integration of symbols and colors.

ISO Standards for Safety Signage

  • The International Organization for Standardization (ISO) standardizes graphical symbols on a worldwide basis.
  • Consistency is key in safety communication on a global scale.
  • Yellow is used on warning signs as the background color for black symbols to indicate potential hazards.
  • Prohibition signs have a red circle with a red slash at a 45-degree angle. They indicate actions that should not be done or potential hazards.
  • Mandatory action signs are blue circles with white graphics. They indicate actions that should be taken to avoid hazards, such as wearing personal protective equipment.
  • Fire equipment symbols include red squares with white flames and white graphical symbols indicating the type of equipment. Green squares with white graphics indicate the location of safety equipment or safe conditions.
  • As you approach a sign, pay attention to both the color and symbol to understand the specific safety message.

Vocabulary

This section explains how different colors and symbols in ISO standards convey different types of safety messages.

Color and Symbol Meanings

  • Yellow: Indicates potential hazards present (used on warning signs).
  • Red: Prohibits certain actions or warns about potential hazards (used on prohibition signs).
  • Blue: Indicates mandatory actions to avoid hazards (used on mandatory action signs).
  • Green: Indicates safety equipment locations or safe conditions (used on green square signs).
  • Pay attention to both color and symbol when interpreting safety messages conveyed by signage.

Clarion Safety Systems is in a unique position to supply product manufacturers, workplaces and public areas with the most up-to-date, standards-compliant safety signs, labels and markings. In 1995, the process began in ISO to re-write the principle global standard pertaining to safety signs and colors, ISO 3864. Mr. Peckham, the founder of Clarion Safety, explains how the International Organization for Standardization (ISO) uses symbols, vocabulary, and color to standardize safety signage on a worldwide basis. Visit the Resource Center on the Clarion Safety website to learn more about the safety standards that apply to your safety signs and labels.

It was in France and so that's why it comes out ISO instead of IOS and the ISO Technical Committee 145 standardizes graphical symbols on a worldwide basis as well as safety sign formats and safety label formats and colors and how you integrate the symbols and colors onto signage. So safety can be communicated on a worldwide basis consistently. That's the key consistency. Yellow is used on a warning sign and get a warning triangle and it's the background color for a black symbol and it indicates that a potential hazard is present. And then there are prohibitions signs it's a red circle with a red slash going through it at a 45 degree angle upper left to lower right. And it has a black graphic symbol behind it. And those signs indicate something that you should not do or you have the potential to interact with a hazard and get hurt. Then you have mandatory action signs and these are blue circles. White graphic and they indicate an action that you should take in order to avoid a hazard. Typically you might use those for like personal protective equipment wearing hardhats or wearing eye protection that type of thing. And then you have the symbols having to do with fire equipment. There are red square with a white flame determinative element and a white graphical symbol indicating what the equipment is such as a fire extinguisher or a fire alarm and then you have green squares with white graphics on them and therefore the location of safety equipment or safe condition like the cross which would be for use for first day. [00:01:38][92.4] [00:01:38] The running man going through an open door and that's indicated there is an emergency exit in this direction. That type of thing. So green red blue yellow in ISO they all indicate a different type of safety message. So as you get closer to the sign you'd see not just the color but the symbol and the symbol would tell you what these specific messages. That's the whole vocabulary of how colors used in ISO.
