Safety Spray Shields are used to prevent injury to personnel or damage to equipment in the event of a leak or spray-out of acids, caustics, chlorine, and other dangerous liquids at piping connections (such as flanges, valves, or expansion joints) found in chemical, pulp/paper, petrochemical and wastewater treatment plants. These Safety Shields are commonly referred to as flange guards, flange covers, flange diapers, or flange protectors
