international safety signs
2introduction
- Signage systems
- lots of signs around us, some standard, some not
so much - Quiz - identify the subject of the sign and how
it is telling you to behave - 25 signs from DIN standard used by UK Health and
Safety - Review of quiz
- scores - what do they tell us?
- Discussion - what makes a good sign system?
- Semiotics - the language of signifiers and
signified
3familiar example - packing signs
4Hans-Rudolf Lutz Die Hieroglyphen von Heute
(1990) (Hieroglyphs of Today) -
http//www.lutz.to/hieroglyphen1.html compendium
of 5,000 international signs and symbols found on
cardboard boxes demonstration of a working
system of signs that has developed without the
formal intervention of graphic designers or
information graphics
5familiar example - laundry symbols
- Groupement International d'Etiquetage pour
l'Entretien des Textiles (International
Association for Textile Care Labelling) - claim to cover 95 of all manufactured textiles
- GINETEX care symbols are registered with the WIPO
(World Intellectual Property Organization)
6 international safety signs
- Three main standards in common usage
- some signs used by all, others are peculiar to
one system - ISO 3864 International Standards Organisation
- includes most of the DIN 4844-2 and adds many
more - ANSI Z.535 American National Standards Institute
- requires text to be used along with pictograms
- DIN 4844-2 Deutsches Institut für Normung
(German Institute of Standardisation) - most familiar to people in the UK and Europe,
generally recognised worldwide
7a short quiz about hazard signs
- DIN 4844-2 warning signs quiz
8three types of safety sign
Hazard warning Corrosive materials
Mandatory Wear protective clothing
Prohibited Do not touch
Subtle difference between the signs - most people
get it, but find it hard to put into words and
describe the precise meaning of the sign
9three types of safety sign
Hazard warning General
Mandatory General
Prohibited General
Cultural knowledge necessary to deduce the
meanings of the signs when pictograms are not
present
10some interesting cases toxic sign
- Skull and crossbones - use as a symbol stretches
back thousands of years - Known to have been used in New York State since
around 1850 to denote poison - HAZMAT EU standard toxic symbol Directive
67/548/EEC - ISO, ANSI, DIN and most other standards use the
same symbol - Very powerful cultural symbol
- does not provide pictorial representation of
hazard (such as falling figure) - could be argued to represent consequences of
hazard (but what about any other hazard?)
11some interesting cases biohazard sign
- Charles Baldwin, Dow Chemical, 1966
- Wanted a sign with no meaning!
- We wanted something that was memorable but
meaningless, so we could educate people as to
what it means. New York Times, 2001 - Designed by marketing department, tested for
recognition - Ease of reproduction - stencilling
- Also needed to work regardless of orientation
- Can be reproduced precisely with compass and
ruler - field work
12some interesting cases radioactive sign
- Originally sketched out by a group of people at
the University of California, Berkeley in 1946 - 1948 letter by Nels Garden described why they
chose it - represented activity radiating from an atom
- magenta symbol on a blue background
- cheap to print
- did not conflict with any other colour code
- blue not common in radiation labs
- later yellow background added to make it clear it
was a warning - ANSI standardised modern symbol late 1950s
-
13electromagnetic
14some interesting cases radioactive sign
- Requirement to represent other types of
radiation - Non-ionising radiation
- Laser radiation
- Optical radiation
- Dilution of the message
- familiarity breeds contempt
- which hazards are the most hazardous?
- how to represent hierarchy?
-
15some interesting cases radioactive sign
- Feb 2007 new sign standardised by International
Atomic Energy Agency, and contained in ISO
214822007 - Purpose is to make it clear to everyone that
there is danger present that will lead to harm
and that they should leave - Result of a five year project
- Tested by Gallup Institute on a total of 1,650
individuals in Brazil, Mexico, Morocco, Kenya,
Saudi Arabia, China, India, Thailand, Poland,
Ukraine and the United States -
16some interesting cases radioactive sign
- Compound nature of the sign
- how many pictograms are present?
- is there a narrative?
- Cultural components of the sign
- on what does an understanding of its meaning
depend? - to whom might it be meaningless?
17semiotics
- Semiotics - the study of signs
- very broad area - means slightly different things
to different people depending on their field - A sign can be anything at all that has meaning
- a road sign, a street name, a map, an atlas
- a letter, a word, a sentence, a book
- a song, a film, a hand gesture, a pose, an idea
- Three main areas to the study of semiotics
- the signs themselves
- the way signs are organised into systems
- the context in which signs appear
- Basic principle is that of signifier and
signified - there cannot be a signifier if nothing is
signified - in order for something to be signified, there
must be a signifier
18introduction to semiotics
- Not a well defined discipline, despite being
established for over 100 years - origins in the work of Ferdinand de Saussure -
Swiss linguist 1857 - 1913 - Semiology - and Charles Sanders Peirce, American philosopher
and scientist 1839 - 1914 - Semiotics - Saussures ideas formed part of a linguistics
course at the University of Geneva 1906 - 1911 - his theories form the basis of modern day
semiotics - he died before publishing them but
- his students assembled them from lecture notes
and published them in 1916 as the Course in
General Linguistics (Cours de linguistique
générale) - Peirce published on philosophy, logic,
mathematics and science - founded Pragmatism - reaction to metaphysics
Do not block the way of inquiry - his work encompasses the theories of semiotics
and he published widely from around 1860 onwards
19introduction to semiotics
- Saussure and Peirce worked independently but had
very similar ideas - Peirce - defined three categories of signs
- Icon - resembles the sign, eg a trip hazard
safety sign, a photograph, a spoken word like
bang! - Index - a direct link between the sign and the
object, eg smoke is a sign of fire, a roundabout
road sign is directly linked to the road junction
it signifies - Symbol - no logical connection between the sign
and what it means, eg the biohazard safety sign,
a countrys flag - Saussure - as a linguist interested mainly in
words and defined only two categories of sign - Iconic - very much like Peirces icon, eg
onomatopoeic words - Arbitrary - as Peirces symbols, there is no
direct relationship between the signifier and the
sign, eg the vast majority of the components of
language
20introduction to semiotics
- A single sign frequently fulfils the requirements
of all categories - the pictogram resembles a hand, so is iconic
- it is part of a set of signs for which we have
international agreement, prohibited, so it is
also a symbol - when it is placed in context it becomes an index
sign, because part of its meaning comes from its
placement in the real world
21introduction to semiotics
- Peirce identifies three properties for signs that
map to his categories - firstness - the sense of a sign, eg anxiety on
seeing the radioactivity sign - secondness - the physical relation of the sign to
reality, eg the proximity of the sign to the
danger it signifies - thirdness - the mental level that brings the
other two together, eg there is danger here, I
feel scared, I must leave!
