Fire retardant paints can be used on plywood for nonstructural interior finish applications such as wall and ceiling paneling to reduce flame spread ratings to 25 or less, depending on the paint selected. These can also be used on other engineered wood products, such as glulam and I-joints for flame spread reduction. There are two broad types of fire-retardant paints. One is a pigmented type designed as a masking finish similar to ordinary paint systems. Most of theses paints typically intumesce or swell to a thick insulating layer when exposed to rapidly rising temperatures. These types of paints are designed for their fire retardant properties and may not provide the full range of colors and decorative effects of conventional finishing systems. The second type of fire retardant paint is a clear finish, similar in appearance to a lacquer or clear varnish, which is used for high appearance paneling such as fine hardwoods.
Fire service turbine is designed for applications where fire service and drinking water supplies are fed by a single line. Its design combines low-slow sensitivity of disc meters with high-flow capacity of turbine meters for an extremely wide flow range. The fire service turbine meter is designed to measure both domestic and fire service water usage through a single water line.
