Signs provide clear, concise information and are often the first warnings people will have about your hazardous substances.
Signs are placed at key points on your site, such as entranceways and on buildings, or in outdoor areas, where hazardous substances are used or stored. They should be clearly visible and let people know that hazardous substances are present, the general type of hazard and what to do in an emergency. This allows people to approach the site with appropriate care.
There are special sign requirements for some substances, for example fumigants and vertebrate toxic agents (VTAs).
When do I need signs?
Signs are required when you have hazardous substances exceeding specified quantities.
Even if you aren’t required to have signs, it is best practice always to have them as they warn other people at the workplace, and emergency services, that hazardous substances are present
