What distinguishes water-mist stored-pressure extinguishers from standard water extinguishers?

Water-mist stored-pressure extinguishers are specifically designed to produce a fine spray or mist that cools and suffocates a fire more effectively than a solid stream of water can. This fine mist minimizes the amount of water needed, reducing the risk of water damage, and helps prevent vaporization of the liquid, thus effectively smothering flames. The fine mist can also travel further and cover a larger area, making it effective for cooling burning materials or preventing ignition of adjacent flammable items.

In contrast, traditional water extinguishers deliver a solid stream of water, which may not be as effective in certain situations, especially when it comes to delicate materials or confined spaces where water could exacerbate fire spread or cause damage. This distinction highlights the specialized purpose behind the design of water-mist extinguishers compared to their standard counterparts.
