First aid kit with three individual protected and separately accessible levels. Each level is its own compartment, where the valuable first aid contents are securely, clearly, and protected stored under a transparent cover plate. The cold packs specified in the current DIN standard for workplace first aid kits are particularly susceptible to self-activation and should therefore be stored extra protected, so that the other sterile contents and dressings are not damaged. For this reason, the Quick-CD Joker first aid kit also has a separate protected level for the cold packs, even during long-term storage. There is still extra space available for personal additions.
