HAZCHEM signage is essential for warehouses that store or handle hazardous chemicals. These signs provide clear, standardised information to identify the nature of chemical hazards, ensuring safety for workers,
emergency responders, and the general public. The HAZCHEM system includes symbols, colour coding, and codes that indicate the type of hazard (flammable, corrosive, toxic, etc.), the appropriate handling and storage procedures, and emergency response actions.

Key requirements for Hazchem signage in New Zealand warehouses are outlined in the Health and Safety at Work (Hazardous Substances) Regulations 2017, which align with international standards for chemical safety. Proper HAZCHEM labelling helps prevent accidents and facilitates safe response in case of emergencies, such as spills, fires, or leaks. Regular audits and training are also required to ensure ongoing compliance with these safety standards.
