🔍 Key Concepts

• Low velocity water fog behavior and droplet size • How water fog interacts with radiant heat and visibility • Differences between removing vapors/fumes vs providing protection

💭 Think About

• Ask yourself what small water droplets in a fog pattern do when they are sprayed between a fire and a person. • Consider whether low velocity water fog is mainly used to change the air’s chemical contents or to change the heat and visibility conditions. • Think about which option best matches a temporary protective barrier rather than a method of permanently eliminating gases or vapors.

✅ Before You Answer

• Verify which choice describes forming a screen or curtain rather than cleaning the atmosphere. • Check which options involve actually removing vapors or fumes from the area; does water fog realistically do that? • Confirm which use of low velocity water fog is emphasized in basic marine firefighting training as protection for the fire party advancing on a fire.
