Many household chemicals can be dangerous and display warning labels. From left to right: white spirit (Danger: serious long term health hazards; harmful to the environment; harmful skin and eye irritation; flammable). Bleach (Danger: severe skin burns and eye damage; harmful to the environment). Tipp-ex rapid correction fluid, (Danger: harmful to the environment; flammable; harmful skin and eye irritation ). In comparison with the older regulations ( See H100/ 1306) from 2006 the warnings have become much more precautious. The international Globally Harmonized System of Classification and Labelling of Chemicals (GHS) recommended in 2009 that the diverse local hazard symbols around the world be replaced by their unified symbols and classifications.
