First Aid certificates are issued at one of 3 levels in Denmark

Level 1 (“Basic First Aid”, or “Basic Life Support”):
is a 1-day course covering primarily life-threatening emergencies: CPR, bleeding, choking and other life-threatening medical emergencies.

Level 2 (“Senior First Aid”)
is a 2 day course that covers all the aspects of training in Level 1, as well as specialized training for treatment of burns, bites, stings, electric shock and poisons. Level 2 re-accreditation is a 1 day course which must be taken every 3 years, but CPR re-accreditation may be required more frequently (typically yearly).

Level 3 (“Occupational First Aid”)
is a 4-day course covering advanced first aid, use of oxygen and automated external defibrillators and documentation. It is suitable for workplace First Aiders and those who manage First Aid facilities.
