ISO 7010 is an International Organization for Standardization technical standard for graphical symbols on hazard and warning signs, including those indicating emergency exits and safety signs. It uses colours and principles set out in ISO 3864 for these symbols, and is intended to provide "safety information that relies as little as possible on the use of words to achieve understanding." It is distinct from the Globally Harmonized System of Classification and Labelling of Chemicals specified by the United Nations to standardise hazardous material classification and labelling.
As of July 2018, the latest version is ISO 7010:2011. This is under review to be replaced with new standard ISO/DIS 7010, which also incorporates water safety signs and beach safety flags previously specified in ISO 20712.
ISO 7010 specifies five combinations of shape and colour to distinguish between the type of information presented.
|Sign type||Meaning||Colour (per ISO 7010)||Shape||Example|
|Prohibition sign||Prohibition||Red||Circle with diagonal line||No open flame|
|Mandatory sign||Must do||Blue||Circle||Use hearing protection|
|Warning sign||Warn of hazard||Yellow||Equilateral triangle with rounded corners||Explosive materials|
|Safe Condition sign||Safety equipment & exits||Green||Square or rectangular||Emergency Assembly Point|
|Fire Safety sign||Fire Protection||Red||Square||Fire Extinguisher|
These are the official numbers and titles of ISO 7010-2011 safety signs.
An emergency exit in a structure is a special exit for emergencies such as a fire: the combined use of regular and special exits allows for faster evacuation, while it also provides an alternative if the route to the regular exit is blocked by fire, etc.
The qualifications for an emergency exit are as follows: it must be in a location that is easily accessible, the exit must have an area or location that it can bring people to in the event of any emergency situation, it must be controlled by the inside of the building, it must be well managed and regularly up kept, and it must be in a permanent location.
It is usually in a strategically located (e.g. in a stairwell, hallway, or other likely places) outward opening door with a crash bar on it and with exit signs leading to it. The name is a reference to when they were frequently used, however, a fire exit can also be a main doorway must be able to be unlocked from the inside of the room. A fire escape is a special kind of emergency exit, mounted to the outside of a building.European hazard symbols
European hazard symbols for chemicals are pictograms defined by the European Union for labelling chemical packaging (for storage and workplace) and containers (for transportation). They are standardised currently by the CLP/GHS classification.Exit sign
An exit sign is a device in a public facility (such as a building, aircraft, or boat) denoting the location of the closest emergency exit in case of fire or other emergency. Most relevant codes (fire, building, health, or safety) require exit signs to be permanently lit.
Exit signs are designed to be absolutely unmistakable and understandable to anyone. In the past, this generally meant exit signs that show the word "EXIT" or the equivalent in the local language, but increasingly exit signs around the world are in pictogram form, with or without supplementary text.First aid kit
A first aid kit is a collection of supplies and equipment that is used to give medical treatment. There is a wide variation in the contents of first aid kits based on the knowledge and experience of those putting it together, the differing first aid requirements of the area where it may be used and variations in legislation or regulation in a given area.
The international standard for first aid kits is that they should be identified with the ISO graphical symbol for first aid (from ISO 7010) which is an equal white cross on a green background.Globally Harmonized System of Classification and Labelling of Chemicals
The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is an internationally agreed-upon standard managed by the United Nations that was set up to replace the assortment of hazardous material classification and labelling schemes previously used around the world. Core elements of the GHS include standardized hazard testing criteria, universal warning pictograms, and harmonized safety data sheets which provide users of dangerous goods with a host of information. The system acts as a complement to the UN Numbered system of regulated hazardous material transport. Implementation is managed through the UN Secretariat. Although adoption has taken time, as of 2017, the system has been enacted to significant extents in most major countries of the world. This includes the European Union, which has implemented the United Nations' GHS into EU law as the CLP Regulation, and United States Occupational Safety and Health Administration standards.ISO 3864
ISO 3864 specifies international standards for safety symbols. These labels are graphical, to overcome language barriers. The standard is split into four parts:
ISO 3864-1:2011 Part 1: Design principles for safety signs and safety
ISO 3864-2:2016 Part 2: Design principles for product safety labels
ISO 3864-3:2012 Part 3: Design principles for graphical symbols for use in safety signs
ISO 3864-4:2011 Part 4: Colorimetric and photometric properties of safety sign materialsISO 7001
ISO 7001 ("public information symbols") is a standard published by the International Organization for Standardization that defines a set of pictograms and symbols for public information. The latest version, ISO 7001:2007, was published in November 2007.
The set is the result of extensive testing in several countries and different cultures and have met the criteria for comprehensibility set up by the ISO. Common examples of public information symbols include those representing toilets, car parking, and information, and the International Symbol of Access.List of International Organization for Standardization standards, 5000-7999
This is a list of published International Organization for Standardization (ISO) standards and other deliverables. For a complete and up-to-date list of all the ISO standards, see the ISO catalogue.The standards are protected by copyright and most of them must be purchased. However, about 300 of the standards produced by ISO and IEC's Joint Technical Committee 1 (JTC1) have been made freely and publicly available.No symbol
The general prohibition sign (official name, according to ISO 7010), also known as a no symbol, no sign, circle-backslash symbol, nay, interdictory circle or universal no, is a red circle with a red diagonal line through it (running from top left to bottom right), completely enclosing a pictogram to indicate something is not permitted. The prohibition sign is sometimes seen in all-black, where color is not available.
The Unicode code point for the prohibition sign is U+20E0, Combining Enclosing Circle Backslash ( ⃠ ). It is a combining character, which means that it appears on top of the character immediately before it, so putting ♪ ⃠ ∞ ⃠ is supposed to show an eighth note inside the prohibition sign, followed by the infinity symbol inside the prohibition sign: ♪ ⃠ ∞ ⃠. It also appears in the Webdings and Wingdings 2 fonts.
There is also a prohibition sign emoji located at U+1F6AB NO ENTRY SIGN (🚫), which does not combine with anything.According to the ISO standard (and also under a UK Statutory Instrument), the red area must take up at least 35 percent of the total area of the sign within the outer circumference of the "prohibition sign". Therefore, 35 percent of everything within the outer edge of the "no symbol" must be the symbol. Additionally, for printed signs under the UK rules, the width of a "no symbol" is set at 80 percent the height of the area to which it is printed.Warning sign
A warning sign is a type of sign which indicates a potential hazard, obstacle or condition requiring special attention. Some are traffic signs that indicate hazards on roads that may not be readily apparent to a driver.While warning traffic sign designs vary, they usually take the shape of an equilateral triangle with a white background and thick red border. In the People's Republic of China (except for Macau and Hong Kong), they appear with a black border and a yellow background. In Sweden, Serbia, Bosnia and Herzegovina, Greece, Finland, Iceland, the Republic of Macedonia and Poland, they have a red border with an amber background. The polar bear warning sign in Svalbard recently changed from displaying a black bear on white background to a white bear on black background (both signs are triangular with a red border). Some countries (like France, Norway and Spain) that normally use a white background have adopted an orange or amber background for road work or construction signs.
Warning signs in some countries have a diamond shape in place of the standard triangular shape. In the United States, Canada, Mexico, Thailand, Australia, Japan, Indonesia, Malaysia, New Zealand, most of South America, and also Ireland (diverging from the standards of the rest of Europe) use warning signs are black on a yellow background and usually diamond-shaped, while temporary signs (which are typically construction signs) are black on an orange background. Some other countries also use these standards for some signage.
The warning signs usually contain a symbol. In Europe they are based on the UNECE Vienna Convention on Road Signs and Signals. In the United States they are based on the MUTCD standard and often contain text only.
