Tags are laminated in plastic so they hold up outdoors. Use them to communicate dangers to workers near equipment that could cause injury. Write on them using a permanent marker. All tags meet OSHA safety color standards for indicating hazards. Attach them with an included cable tie. Danger headers are typically used in extreme conditions to indicate an imminently hazardous situation that, if not avoided, will result in death or serious injury. Caution headers indicate a potentially hazardous situation that, if not avoided, may result in minor or moderate injury
