The only official UK standard for first aid kit contents is the British Standard BS8599-1. The HSE provides some guidance on the type of items that should be in a first aid kit, but not the quantities. The old BHTA standard kit 10, 20 and 50 (often called HSE kits), are now obsolete and withdrawn. The British Standard BS8599-1 Compliant kits, now provide employers with a means by which they can choose a kit that matches their risk needs assessment, while still demonstrating compliance with the spirit of the legislation. Some employers may have diverse or unusual situations and will need to make bespoke provision for such risks, these situations however, are not likely to be typical. The BS8599-1 compliant first aid kits will be suitable for most situations.
