Signs that prohibit certain behaviour or actions. Prohibition signs appear with a red cross out circle over the action symbol in black. Sign wording is in black on a white background. These signs are located at the site where the behaviour or action is prohibited. Our prohibition signs comply with Australian Standards 1319 and include a wide range of standard and custom prohibition signs including no smoking signs, no entry signs and restricted entry signs. Prohibition Signs and stickers assist the management of a safe and productive work site. We manufacture our safety signs on site and stand by our product.
