Since fire tends to travel uphill, it's generally preferable to locate the flammable storage area uphill of the process area.

Since fire tends to travel uphill, it's generally preferable to locate the flammable storage area uphill of the process area.

• A. Depends on humidity
• B. False
• C. Depends on wind
• D. True

Answer: (B)

Fire spreads uphill because hot gases rise, so flames can reach higher areas more easily. Placing a flammable storage area uphill of the process area creates a greater chance that heat and flames will reach and ignite the process area, increasing risk. For safety, storage should be separated from the process area and not placed at a higher elevation that could help the fire travel upward. Wind and humidity can affect vapor movement, but they don’t justify putting storage uphill; the priority is to minimize heat exposure and ignition risk to the process area.
