of the common GHS scheme for quick checks. Always confirm against the current SDS Section 2 and your regulator's version (OSHA 29 CFR 1910.1200, EU CLP, and others differ in adopted categories). ## Content **Intro:** This table maps each GHS hazard class and category to its pictogram code and signal word. Use it to check a supplier label against an SDS, build training material, or classify rows in a chemical inventory. **Sections:** #### How to use the table **Body:** Type a hazard class, a pictogram code such as GHS06, or a signal word into the search box to filter the rows. Compare the result to Section 2 of the safety data sheet and to the label on the container. If the label shows a different pictogram than this table suggests, check whether the product carries several hazard classes, because one pictogram can cover more than one class and a higher-priority symbol can replace a lower one. #### The rules behind pictograms and signal words **Body:** GHS uses nine pictograms. The signal word is Danger for the more severe categories and Warning for the less severe, and a label carries only one signal word. Precedence rules reduce clutter: for example the skull and crossbones replaces the exclamation mark for acute toxicity, and the corrosion symbol replaces the exclamation mark for skin and eye irritation. The environmental pictogram is not mandatory under OSHA HazCom. **Bullets:** - Danger always outranks Warning on a single label - Skull and crossbones takes precedence over exclamation mark - Corrosion takes precedence over exclamation mark for skin or eye effects - Health hazard (GHS08) is for chronic and systemic effects, not acute poisoning - Category 4 flammable liquids carry a signal word but no pictogram #### Common mistakes **Body:** The most frequent error is treating the exclamation mark as a catch-all and leaving out the health hazard symbol on carcinogens or sensitizers. Another is relying on an old NFPA diamond or HMIS rating in place of GHS labels on shipped containers. Those workplace systems can still be used internally but do not replace the supplier label. Finally, check that secondary containers are labeled with at least the product identifier and the hazard words or pictograms. **Cta:** If your chemical inventory sits in an ERP item master, we can help you carry hazard class and pictogram data onto item records so it is searchable next to stock and purchasing. **Faq:** #### Which pictogram does OSHA require? **Answer:** OSHA HazCom 2012 requires pictograms for eight of the nine symbols. The environmental pictogram (GHS09) is allowed but not mandatory. Each label must also show the product identifier, signal word, hazard statements, precautionary statements and supplier details. #### Can a product have both Danger and Warning? **Answer:** No. If any hazard class in the product warrants Danger, the label shows Danger only. Warning appears only when every applicable category is at the lower severity level. #### Does GHS replace NFPA 704 diamonds? **Answer:** No. NFPA 704 is a fire and emergency response marking for buildings and storage areas. GHS labels are for containers. Many sites use both, and they have different scales and purposes. #### Is this table a legal classification? **Answer:** No. It is a quick reference. Classification of a mixture depends on test data and cut-off values, and the supplier's SDS is the authoritative source for the product you have. ## Search terms GHS pictograms and meanings, GHS signal word danger or warning, GHS hazard class categories table, HazCom label pictogram chart, GHS01 GHS02 GHS03 GHS04 GHS05 GHS06 GHS07 GHS08 GHS09, SDS section 2 hazard classification, OSHA hazard communication pictogram list --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
