Final answer:
Before pulling the hose from the bed during a lower floor fire, the engine should assess the situation, ensure proper hose connection and water pressure, and communicate and coordinate with team members.
Step-by-step explanation:
In the event of a lower floor fire, the engine should perform several tasks before pulling the hose from the bed. First, they need to assess the situation and gather information, such as the location and extent of the fire, the presence of any hazardous materials, and the condition of the building. This helps them determine the appropriate firefighting tactics.
Next, they should ensure that the hose is properly connected to a water source, check the water pressure, and make sure the nozzle is in the closed position. This prevents any unnecessary water flow or leaks.
Finally, they should communicate with their team members to coordinate their actions and establish a plan. This includes establishing a water supply line and assigning specific tasks to each firefighter.
