IN ONE LINE
GHS gives every chemical the same label grammar: pictogram, signal word and standard phrases.
WHAT YOU'LL LEARN
Decode a GHS label's pictogram, signal word and codes.
Distinguish "Danger" from "Warning" severity.
Apply correct labelling to secondary containers.
READ THE LESSON
One global grammar
The Globally Harmonised System means a corrosive label in Jakarta reads the same as one in Berlin. Learn the nine pictograms once and you can read any compliant label.
Two words, two levels
"Danger" marks the more severe hazard category; "Warning" the less severe. The signal word is the fastest read on the whole label.
Your decant needs a label too
The moment you move chemical into a beaker or wash bottle, it becomes a secondary container that must show identity and hazard — unless you'll use it up immediately yourself.
Nine pictograms
Flame, corrosion, skull, health hazard, exclamation, exploding bomb, flame-over-circle, gas cylinder, environment.
