== Hazard ==
The start of any bowtie is the 'hazard'. A hazard is something in, around or part of the organization which has the potential to cause damage. Working with hazardous substances, driving a car or storing sensitive data are for instance hazardous aspects of an organization while reading this article on your computer is not. The idea of a hazard is to find the things that are part of your organization and could have a negative impact if control over that aspect is lost. They should be formulated as normal aspects of the organization. The rest of the bowtie is devoted to how we keep that normal but hazardous aspect from turning into something unwanted. The first step is always the hardest and this is also the case here. Normally, starting with for instance a HAZID is a good way to get a long list of all possible hazards. Bowties are then done only for those hazards with a high potential to cause extensive harm. Normally, 5 to 10 hazards is a good starting point.
