Industrial safety footwear guidelines

The image shows a safety sign posted on a beige concrete pillar inside an industrial facility. The sign reads ‘SAFETY FOOTWEAR RULES’ in bold letters at the top. Below, it has three images: one of a black closed-toe industrial boot with a green checkmark and the text ‘CLOSED TOE REQUIRED’, and two others showing prohibited footwear—flip-flops and casual sneakers, both marked with red Xs along with the text ‘NO OPEN-TOE OR UNSAFE FOOTWEAR’. The background reveals a factory setting with yellow safety lines and metal railings, emphasizing workplace safety requirements for footwear.
