What is the relationship between hazards and harm?

Risk assessment involves describing the relationships between a hazard (a potential source of harm) and the ultimate consequences in terms of physical injury or damage. For some devices, non-physical injury, such as psychological harm, should also be considered. As part of their risk assessment, manufacturers should analyze possible sequences of events, hazardous situations, and associated possible harm. This may include:

• initiating hazards, failure modes, or circumstances;
• the sequences of events that could lead to a hazardous situation occurring;
• the likelihood of such situations arising;
• the likelihood that the hazardous situations lead to harm; and
• the nature of the harm that could result.
