The assertion that the initial resources dispatched are usually enough to manage most incidents is true because, in many situations, first responders make a rapid assessment and send a level of resources designed to efficiently handle the incident based on available information during the initial stages. This assessment takes into account the type and scale of the incident, and resources are optimized to ensure an effective response.
In practice, local emergency response protocols often aim to provide an adequate first response that can stabilize the situation, prevent further harm, and control the incident until additional resources can be deployed if necessary. This approach is based on principles of incident management where the objective is to quickly address and mitigate issues before they escalate.
The effectiveness of the initial resources may vary depending on the nature of the incident, yet the intention is usually to ensure that a prompt and sufficient level of response is available. The specific choices regarding the number and type of resources dispatched are targeted to reflect common scenarios encountered by responders, leading to the conclusion that in most instances, the initial resources are indeed enough to manage the situation effectively.
