Water curtains do not protect exposures.

Water curtains are used primarily as a means of cooling and protecting structures from heat and smoke during a fire. They create a barrier of water droplets that can help mitigate the spread of fire and limit damage to the environment. However, while they can be effective in cooling surfaces and providing a layer of protection, they do not completely shield exposures from all potential fire hazards.

The function of a water curtain is to reduce heat intensity and manage smoke movement, but it does not eliminate the risk of ignition or damage from direct flame contact or radiant heat. The effectiveness of water curtains depends on various factors, including the distance to the fire, the water pressure, and the volume of water used. Therefore, it is accurate to state that water curtains, while beneficial in some aspects, do not offer complete protection against all forms of exposure to fire.

This understanding clarifies that a water curtain can assist in fire scenes but cannot guarantee total protection for exposures, supporting the assertion that water curtains do not protect exposures.
