What should be in place when performing a Defensive Strip?

Explanation:
Defensive strip is a roof operation to remove roofing material and create a vent, while keeping the fire under control. Having a charged hose line in place before you start is essential because it gives you immediate water to cool the roof, manage heat and flame, and suppress any sudden extension as you expose the area. Water applied during the strip helps prevent flashover or flare‑ups and protects crews working on the roof. The other options describe variations of where the strip is performed in relation to structural members (off beam, off purlin) or a diagram reference. These details matter for technique, but they don’t replace the fundamental need for a hose line ready to control the fire during the operation.
