During which type of incident may alternative communication methods be required?

In incidents that are large-scale and expected to last for a long duration, alternative communication methods may become necessary due to various challenges that can arise. Such incidents often involve multiple agencies, a higher number of responders, and potentially complex logistics, all of which can lead to communication breakdowns.

Traditional methods of communication, such as radios, may become overloaded or ineffective in environments with high noise levels or when equipment is damaged. Therefore, it is critical to establish alternative communication systems that can support situational awareness, coordination, and information dissemination among responders and command staff. These might include systems like mobile command posts, satellite phones, or informal relay systems using runners or messengers.

Conversely, in a single-company response or a short-duration incident, the need for alternative communication methods is less pronounced as the scale and complexity of operations can typically be managed through standard communication protocols. Additionally, community events may also utilize basic communication methods which are usually adequate for the smaller and less complex nature of these situations.
