| Where should a fire be attacked from, whenever possible? | From the unburned side |
| A portable unit that can either be mounted or detached from an apparatus | Master Stream appliance |
| According to the Standard for Automotive Fire Apparatus, what is the recommended gpm at minimum to flow from a master stream appliance | 100 gpm |

| According to the Standard for Automotive Fire Apparatus, the pump intake connections should be what size? | they must be at least equal in size to the size of the suction lines. |
| When are the 3 benefits of front water intake connections? | when drafting, allows better positioning; when at a fire, allows the engine to get closer to the curb while keeping the wheels on firm ground |
| What are the two instances that Pump Intake Connections are used? | Soft-suction for hydrant operations, and drafting with hard-suction hose |

| What is the hose lay where the pumper advances straight to the firescene, bypassing the watersupply completely? | Direct to fire, no line approach. |
| In what areas is the direct to fire, no line approach a common practice? | Areas that do not have a hydrant system |
| What is the one advantage reverse lay has over the other lays? | It places the pumper out of the way of the scene, so as not to interfer with incoming units, and to stay out of high heat or fall zones |
