Symbols/pictograms in the GHS
Same symbols (where there is commonality) and pictogram shape for transport and supply (square on point)
Transport pictograms will use the background and symbol colour specified in the UN RTDG Model regulations
For supply, pictograms will contain a black symbol on a white background with a red frame

Signal words“Danger” or “Warning”
Used to emphasis hazard and to discriminate between hazard categories (level of hazard)
e.g. Acute toxicity category 1 will require “Danger”, category 4 will require “Warning”

Hazard statements A single harmonised hazard statement for each hazard
category within each hazard class
e.g.Category 1 Flammable liquid
“extremely flammable liquid and vapour”Category 2
“Highly flammable liquid and vapour”Category 3 - “flammable liquid and vapour”Category 4 - “combustible liquid”

serious eye damageHighly flammable liquid and vapourAvoid contact with skin and eyesKeep away from heat and ignition sources
First aid:For skin contact, remove contaminated clothing and wash affected area thoroughly with
water. If irritation develops, seek medical attention.For eye contact, immediately flush eyes with flowing water for at least 15 minutes and seek
medical attention.GHS Example Company, Akron, NWT, Canada. Telephone (888) 888-8888

Dual labelling for transport and supply
Concern about GHS supply pictograms appearing on single packages which also are labelled with UN pictograms, potential for confusion, e.g. in postal sorting offices
Study carried out by US
Conclusion: clearer guidance needed in GHS to ensure differentiation between transport-regulated classes and other classes

Conclusions
Difficult, long-term process, much work still to be done By UN SCE GHS Subcommittee By countries when GHS is introduced
Significant benefits more logical system economic
Will be easier for small businesses to comply and will improve comprehensibility for users
