The GHS (Globally Harmonized System) hazard symbols on chemical bottles or storage cabinets signify specific types of chemical hazards. Each symbol provides a quick visual indication of the nature of the chemical risk:

• GHS01 Exploding Bomb : Indicates chemicals that can explode due to heat, impact, or friction, warning of explosive hazards

• GHS02 Flame : Signifies highly flammable substances that can ignite easily on contact with sparks, flames, or heat, including risk of spontaneous combustion

• GHS03 Flame Over Circle : Represents oxidizing agents that can cause or intensify fires by releasing oxygen

• GHS04 Gas Cylinder : Warns of compressed, liquefied, or pressurized gases that may cause suffocation, poisoning, burns, or explosion if released

• GHS05 Corrosive : Indicates substances that cause severe skin burns and eye damage, and can corrode metals

• GHS06 Skull and Crossbones : Denotes acute toxicity; chemicals that can cause serious health effects or death even in small amounts by inhalation, ingestion, or skin contact

• GHS07 Exclamation Mark : Signals less severe health hazards such as skin irritation, allergic reactions, or other harmful effects that may develop over time

• GHS08 Health Hazard : Used for chemicals causing long-term health effects like carcinogenicity, respiratory sensitization, reproductive toxicity, or organ damage from prolonged exposure

• GHS09 Environment : Indicates chemicals that pose a danger to the aquatic environment, causing long-term damage to aquatic life

These pictograms are standardized with a red diamond border and black symbols on a white background to ensure international recognition and safety in handling chemicals

. They help users quickly identify the type of hazard and take appropriate precautions. In summary, the GHS symbols classify chemicals by physical hazards (explosive, flammable, oxidizing, gas under pressure, corrosive), health hazards (acute toxicity, irritant, long-term health effects), and environmental hazards (aquatic toxicity)
