Close-up image of a warning sign. Signs are posted on a machine to inform us of danger points. Warning signs may be used in conjunction with signs that give specific information about the hazards involved, training required, or specific job duties that they pertain to. A red sign indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. This sign warns workers that lockout/tagout must be used when performing servicing and maintenance to prevent injuries from hazardous energy.

[Photo description: Photo includes a red warning sign with the following text: Warning. Lock-out all machinery prior to servicing. Failure to comply will result in disciplinary action.]
