Normal sterile solution in sachets are ideal for keeping in first aid kits or emergency eye stations.
Health and safety (first aid) regulations
Where mains tap water is not readily available for eye irrigation, at least one litre of sterile water or sterile saline (0.9%) in sealed, disposable containers should be provided.
Once seals are broken, containers should not be kept for reuse.
Containers should not be used after the expiry date.
