KV-LITE TEC powder should be applied gently, through diffuser of fire extinguisher or through an automatic powder dispensing systems. High pressure may splash the burning metal & fire may start at other place. Dry powder can also be manually applied on burning metal by a scoop, shovel or a plastic bag. Care should be taken to cover the surface completely without pinholes and then be left undisturbed for at least 30 to 45 minutes.
