The National Marker Company tag has the legend “DANGER - DO NOT OPERATE” on the front and the legend “DANGER - EQUIPMENT LOCKED OUT BY” on the back. It is often seen in industrial or manufacturing facilities and hospitals. It has space to mention remarks and personnel details and urges that the indicated equipment must not be operated. The bilingual danger tag is printed in both English and Spanish to make it easy for the Hispanic workers to understand the message. The OSHA tag uses contrasting colors to ensure clear visibility from a distance and in most lighting conditions. Using safety tags that carry important warnings or status updates are a part of common safety measures in many places.
