Step-by-step explanation:
The first arriving large fire apparatus should be positioned to create a Traffic barrier and Safe zone.
To help with traffic calming, cones and spotters/flaggers can be used. Cones can be set up to create a secure perimeter and spotters/flaggers can help direct traffic and ensure safety.
By positioning the fire apparatus strategically, it helps provide a safe zone for emergency responders to work in and prevents the public from entering dangerous areas.
