Prohibition Safety Signs should be displayed to advise and remind of actions that must be stopped or are not permitted in the interest of health and safety. Since the introduction of the smoking ban and the Smoke-free (Signs) Regulations 2007, it has been necessary to remind those in the vicinity that smoking is not permitted indoors. Our range of Prohibition Signs assist in compliance with the Health and Safety Signs & Signals Regulations 1996 and conform to EN ISO 7010:2012 by featuring a round red symbol of at least 35% of the total sign area, with a black pictogram and white background. Manufactured in the UK from durable materials that will stand the test of time, these high quality signs are screen printed to ensure long lasting clarity of message.
