Why this sign: This sign should be posted at any tap, pipe or water outlet that supplies non-potable water, such as grey water, recycled water or untreated supplies, to prevent people from drinking or using it for food preparation. It addresses the risk of illness or contamination caused by consuming water that does not meet drinking-water standards.

Compliance note: In Ireland, employers must provide appropriate safety signage where hazards cannot be avoided or adequately reduced by other measures, based on the workplace risk assessment, under the Safety, Health and Welfare at Work (General Application) Regulations 2007. This sign is suitable for use as part of a workplace safety-signage system where identified by that risk assessment.
