Smoking Prohibited safety signs (ZP 1) are used to enforce 'No Smoking Compliance' in enclosed areas such as workplaces and restaurants, at building entrances. These signs are placed anywhere inside or outside your company/factory, where you think someone might mistake the area for a smoking area.
This sign is also used in areas where there are gases or flammable liquids as a prohibitory sign that can be used in conjunction with No Open Flames sign (ZP 2) and with No Cellphones (ZP 27).
