| Description | CLP Hazard Pictogram | Meaning | Storage | Chemicals | Segregate From: |
| Explosive materials |  | Unstable explosive chemicals | Store in a secure location away from all other chemicals | Tri-nitro compounds, Heavy metal azides | All other chemicals |
| Flammable |  | Flammable liquids, gasses or solids. | Flammable storage cabinet | Acetone, Benzene, Methanol | Acids, Bases Oxidisers, Poisons |
| Oxidising Substances |  | Spontaneously evolve oxygen at room temperature or with slight heating. | Separate non-combustible cabinet | Hydrogen Peroxide, Halogens, Nitrate Compounds | Flammables Reducing Agents |
| Pressurised Gas |  | Includes flammable, oxidising & poisonous gasses. | Store in a cool, dry area in secure upright cylinders | Flammable – Methane, Oxidsing – Chlorine, Poisonous – Carbon Monoxide | Segregate oxidising, flammable & poisonous gas from one another.
|
| Corrosive |  | Will cause serious skin burns or eye damage. Also corrosive to metals. | Store in a protected acid/alkali storage cabinet | Acids – hydrochloric acid, sulfuric acid. Alkali – Ammonium hydroxide. | Flammables, Segregate acids from alkalis, Oxidisers |
| Toxic |  | Acute toxicity (oral, dermal, inhalation), Very toxic (fatal), Poison | Store in a vented, cool dry area in a chemically resistant secondary container | Cyanides | Flammables, Acids & Bases, Oxidisers |
| Irritant Harmful Substance |  | Health hazards are less serious but still harmful. | Store in a cool, dry, hazardous cabinet labelled correctly | Bleach, Chemicals in household cleaning products | Explosive materials |
| Long term Health Hazard |  | Poses a serious long-term health risk and includes carcinogens and mutagens. | Keep in limited quantities in a secure hazardous chemical cabinet, locked and labelled. | Asbestos, Benzene, Vinyl Chloride | Flammables, Corrosives, Explosive chemicals |
| Hazardous to Environment |  | Hazardous to the aquatic environment & the Ozone layer. | In a cool, dry area in a labelled hazardous cabinet | Zinc Oxide | Explosives |
