What type of fire stream is used to manage burning flammable liquids safely?

Using a wide-angle or penetrating fog pattern is effective for managing burning flammable liquids due to its ability to create a barrier against heat and improve visibility while fighting the fire. This type of stream breaks up the water into smaller droplets, allowing for better absorption of heat and quicker cooling of the fire. The fog pattern also helps to displace flammable vapors and can be directed towards an area to help control the spread of the fire.

In contrast, other types of streams might not provide the same level of safety or effectiveness. A straight stream can be too direct and may cause flare-ups when aimed at burning liquids, while a solid stream lacks the cooling effect provided by a fog pattern. A high-pressure stream could potentially spread flames or vapors due to its force, making it less suitable for flammable liquids, which require careful handling to prevent escalation of the fire.
