Which factor does not impact the complexity of an incident?

The complexity of an incident is influenced by various factors that directly affect how the situation is managed and resolved. Resource availability refers to the amount and type of equipment, personnel, and materials that can be brought to bear on an incident, which is critical for effective response strategies.

Environmental conditions also play a significant role, as factors like weather, terrain, and accessibility can impact operational effectiveness and safety. Public safety requirements serve to ensure that the health and safety of citizens and responders are prioritized, thus influencing the strategies implemented to manage the incident.

Cost considerations of responding agencies, while important for budgeting and resource allocation, do not inherently affect the complexity of the incident itself. Unlike the other factors that directly impact the operational aspects and strategies during an incident, cost does not change the nature of the incident's response but rather concerns logistical and financial planning.
