When is linear blocking positioning considered appropriate?

Linear blocking positioning is considered appropriate in situations where oncoming traffic is minimal and traffic speed is low because it provides a safe means of protecting the incident scene and responders. This form of positioning involves placing a blocking apparatus, such as a fire apparatus or emergency vehicle, strategically to create a barrier between the responders and any potential hazards from moving traffic.

When oncoming traffic is minimal and speeds are low, responders can ensure a safer environment while they manage the incident. This positioning allows for better visibility and control of the scene, facilitating safe operations without the added risk that comes from fast-moving vehicles or high traffic volumes. It also helps to minimize traffic disruptions while maintaining responder safety. In contrast, heavy and fast-moving traffic can undermine the effectiveness of linear blocking, as the risk of collision and complication increases significantly in those scenarios.
