What is the difference between GHS and CLP?

GHS is the UN Globally Harmonised System; CLP is the EU regulation that implements it into law. The pictograms, codes and hazard classes are the same. The US implements GHS through OSHA's Hazard Communication Standard (HazCom 2012).

What do the signal words Danger and Warning mean?

They flag the severity within a hazard class. Danger is used for the more severe hazard categories; Warning for the less severe. A label shows only the single most severe signal word that applies across all its hazards.

Why do some products show no pictogram?

Some hazards, such as certain skin or eye irritants in the lowest category, require a signal word and hazard statement but no pictogram. The absence of a symbol does not always mean a product is hazard-free.

What is the difference between GHS07 and GHS08?

GHS07 (exclamation mark) covers lower-level effects: irritation, skin sensitisation, acute toxicity category 4 and narcotic effects. GHS08 (health hazard) covers serious, often long-term effects: carcinogenicity, mutagenicity, reproductive toxicity, respiratory sensitisation and aspiration hazard.

The GHS hazard pictograms

The UN Globally Harmonised System (GHS) defines nine hazard pictograms — red-bordered white diamonds with a black symbol — that appear on chemical labels worldwide. They are coded GHS01 to GHS09 and adopted into law through the EU CLP regulation and the US OSHA HazCom 2012 standard.

How it works

Each pictogram corresponds to one or more hazard classes. The flame (GHS02) marks flammables and self-reactives; the skull and crossbones (GHS06) marks acute toxicity; the health hazard symbol (GHS08) marks carcinogens and other serious long-term effects. A label also carries a signal word — Danger for the more severe categories or Warning for the less severe — plus hazard (H) and precautionary (P) statements.

This reference lists every pictogram with its code, name, signal word tendency, the hazard classes it represents, and example substances. The search box filters all columns.

Tips and example

A bottle of bleach typically shows GHS05 (corrosion) with the signal word Danger. A solvent such as acetone shows GHS02 (flame) and GHS07 (exclamation mark). The exclamation mark (GHS07) and the health hazard (GHS08) are easy to confuse: GHS07 is short-term irritation, GHS08 is serious chronic harm. Always read the H-statements, not just the symbol.
