Taking part in an operation to provide support and assistance to the casualties of humanitarian emergencies is a rewarding but challenging experience, often very different from the life you live at home. Your role as a field staff member, and the roles of others at MSB, are crucial for the successful outcome of an operation. This handbook is intended for field staff who are about to take part in an operation with MSB. It contains hands-on advice and answers to questions about your employment at MSB. As a field staff member you have to take responsibility for actively seeking information and answers to questions that may come up during an operation. The advice and guidelines provided in this handbook are general; for more specific questions, you need to consult with your programme officer.
