An acute lack of access to insulin may arise in an unpredictable manner because of sudden crises or natural disasters. In recent years, there have been wars, floods and economic crises in many countries.
The International Diabetes Federation has on several occasions assisted its Member Associations in procuring insulin and diabetes supplies for disaster areas. IDF collaborates with major insulin and diabetes supplies manufacturers and other not-for-profit organisations, such as Insulin for Life Australia  to distribute emergency supplies in situations of acute need. Most major companies have an established system to deal with emergencies and disasters.
