Most workplaces store some hazardous chemicals: cleaning products, pool chemicals, fuels, solvents, acids or fertilisers. Clear signs on stores, cabinets and rooms tell people what's inside, how to stay safe and where to find help if something goes wrong. This guide covers the chemical storage signs we're asked about most.
Hazardous chemicals are covered by WHS laws (including the GHS labelling system) and, for larger quantities, dangerous goods rules that may require placards. This guide is general information. Your safety data sheets (SDS), safety adviser and regulator set what your site needs.
