GHS Labels and Hazard Pictograms Explained

GHS labels are the standardised warning labels on cleaning and sanitising chemicals used in Australian kitchens. Each label carries hazard pictograms (red-bordered diamonds), a signal word (Danger or Warning), hazard statements and precautionary statements. Together they tell staff how dangerous a product is, how it can harm them, and how to use, store and respond to spills safely before they ever touch the container. Key takeaways: GHS is the Globally Harmonised System of Classification and Labelling of Chemicals — it standardises the warning label on hazardous products so the meaning is the same everywhere.. Every compliant label has six core elements: product identifier, pictograms, a signal word, hazard statements, precautionary statements, and supplier details.. The signal word tells you severity at a glance: 'Danger' is more severe, 'Warning' is less severe.. The red-bordered diamond pictograms show the type of hazard — corrosive, toxic, flammable, harmful and so on — so staff can react correctly without reading the whole label.. The label is the quick reference; the Safety Data Sheet (SDS) is the full detail. Keep both accessible and train staff to read them.. What GHS is and why kitchens use it GHS stands for the Globally Harmonised System of Classification and Labelling of Chemicals — an international framework that standardises how chemical hazards are described and labelled. In Australia it underpins the workplace chemical labelling rules that apply to the sanitisers, degreasers, oven cleaners, dishwasher chemicals and pest products found in almost every commercial kitchen. Before GHS, one supplier's 'caution' could be another's 'danger', and pictograms varied. Now a corrosive product carries the same red-bordered diamond whether it came from one brand or another, so a chef, cleaner or new casual can read the risk instantly. Chemical safety sits alongside your food-safety obligations rather than replacing them. Standards 3.2.2 and 3.2.2A in the Food Standards Code deal with food-handling and food-safety management, while workplace chemical labelling is governed by work-health-and-safety law. Requirements and enforcement vary by state and territory — confirm the specifics with your local regulator or work-health-and-safety authority. The six parts of a GHS label A compliant hazardous-chemical label brings together six elements. Learning to scan them in order turns a wall of small print into a fast safety check. Product identifier — the chemical or product name, matching the name on the Safety Data Sheet.. Pictogram(s) — red-bordered white diamonds showing the hazard type.. Signal word — either 'Danger' (more severe) or 'Warning' (less severe); only one appears.. Hazard statement(s) — standardised phrases describing the hazard, e.g. 'Causes severe skin burns and eye damage'.. Precautionary statement(s) — what to do about it: prevention, response, storage and disposal, e.g. 'Wear protective gloves' or 'IF IN EYES: rinse cautiously with water'.. Supplier identification — name, address and contact details of the manufacturer or importer.. Signal words: Danger vs Warning The signal word is the fastest severity cue on the label, and there are only two. 'Danger' is used for the more severe hazard categories; 'Warning' is used for the less severe ones. A product will carry one signal word, not both, based on its most serious classified hazard. For kitchen staff this is a useful triage tool. A concentrated caustic oven cleaner or a strong acidic descaler will typically read 'Danger', signalling that even brief skin or eye contact can cause serious harm and that full personal protective equipment is essential. A milder detergent might read 'Warning'. Never treat 'Warning' as 'harmless', though. It still means the product is classified as hazardous and must be handled with the precautions the label sets out. When no signal word appears at all, the product has not been classified as hazardous under the system — but you should still follow the manufacturer's directions. Reading the hazard pictograms The pictograms are the part most staff recognise. Each is a white diamond with a red border and a black symbol, and each maps to a family of hazards. You don't need to memorise the chemistry — just the response each symbol demands. Corrosion (a test tube dripping onto a hand and a surface) — corrosive to skin, eyes or metals. Common on oven cleaners, descalers and some dishwasher chemicals. Wear gloves and eye protection; never mix with other products.. Exclamation mark — harmful, irritant, may cause skin or respiratory irritation. Common on general detergents and sanitisers. Avoid skin and eye contact and wash hands after use.. Flame — flammable. Some solvents, aerosols and spirit-based cleaners. Keep away from heat, sparks and open flame; store correctly.. Skull and crossbones — acute (severe) toxicity; can cause serious harm or death from small exposures. Rare in general cleaning but possible with some pest products; handle strictly per the SDS.. Health hazard (a figure with a star burst on the chest) — may cause longer-term effects such as respiratory sensitisation or organ effects with repeated exposure.. Gas cylinder, environment (dead tree and fish), and oxidiser (flame over a circle) — for compressed gases, environmentally hazardous substances and oxidising agents respectively; less common in kitchens but worth recognising.. Hazard and precautionary statements in practice Pictograms tell you the type of hazard; the hazard and precautionary statements tell you exactly what could happen and what to do. Hazard statements are standardised phrases such as 'Causes serious eye irritation' or 'Harmful if swallowed'. Because the wording is fixed, staff learn to recognise the phrases across every product. Precautionary statements are grouped into prevention, response, storage and disposal. Prevention tells you what protective equipment and controls to use; response covers first aid and spills; storage tells you how and where to keep the product; disposal covers safe discarding of the product and its container. In a busy kitchen, the response statements matter most in an emergency. If a caustic cleaner splashes into an eye, the label's 'IF IN EYES' instruction is the immediate action while someone retrieves the SDS and seeks medical help. Make sure staff know where first-aid facilities and eyewash are before they open the container. Labels, decanting and Safety Data Sheets A frequent kitchen risk is decanting — pouring a concentrate into an unlabelled spray bottle or a reused drink container. Once a chemical leaves its original labelled packaging, the hazard information travels with the original container, not the bottle in someone's hand. Any container a chemical is transferred into should carry, at minimum, the product name and the relevant hazard information so the next person knows what it is. Never store chemicals in food or drink containers, and never store them near or above food, food-contact surfaces or packaging. This keeps chemical safety and food safety aligned and reduces the risk of contamination. The label is the summary; the Safety Data Sheet is the manual. The SDS gives the full composition, first-aid measures, handling and storage detail, and emergency information. Keep a current SDS accessible for every hazardous chemical on site and make sure staff know where the folder or digital copy lives. Requirements for SDS access vary by jurisdiction — confirm with your work-health-and-safety regulator. Checklist: Every chemical container carries its original GHS label, intact and legible.. Any decanted container shows the product name and hazard information.. No chemicals are stored in food or drink containers.. Chemicals are stored away from and below food, food-contact surfaces and packaging.. A current Safety Data Sheet is accessible for every hazardous chemical on site.. Staff can identify the corrosion, flame and exclamation-mark pictograms and know the response.. Personal protective equipment named on the labels (gloves, eye protection) is available where chemicals are used.. Staff know where first aid and eyewash facilities are located.. Common mistakes: Treating a 'Warning' signal word as meaning the product is harmless — it still means the product is classified as hazardous.. Decanting concentrates into unlabelled spray bottles or reused drink containers.. Mixing chemicals — for example a bleach-based sanitiser with an acid descaler — which can release dangerous gases.. Storing cleaning chemicals above or beside food, ingredients or packaging.. Assuming staff will read the SDS in an emergency instead of learning the label's response statements in advance.. Ignoring the pictograms because the print is small — the diamonds are designed to be read at a glance..
