Keep your cleanroom from contamination by clearly displaying cleanroom locations
These signs are intended to indicate potential, type, and degree of the hazard that may lead to accidental injury or property damage. Signs define specific hazards by conveying a clear, easily understood message. The sign headers and colors used in accident prevention safety signs are specified by OSHA and ANSI to designate the severity of the hazard. Each color has a specific role.
WARNING (orange): Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
