A few years back, I had the opportunity to take on a consultancy assignment in deepest Africa. Before I could go, I had to complete an e-learning course around issues of health, safety and security. As I found out, in some parts of the world safety and security are very important issues, with real risk of deadly diseases, kidnappings, muggings, not to mention getting caught up in wars or terrorist incidents. There’s a lot that can go wrong if you don’t know what you’re doing.
