Abstract: A system, that incorporates one or more enclosures constructed around one or more objects at which, “hot work” is to be performed at a facility at a first location containing flammable or combustible materials. The one or more enclosures are capable of being simultaneously and independently controlled and monitored by a single control and monitoring system which is capable of being in radio communication with a control system at a second, but remote, location.

Abstract: An enclosure constructed around an area at which hot work is to be performed at a facility containing flammable or combustible material. Hot work includes such things as welding, torch cutting, grinding and the like. Facilities include petroleum drilling and production platforms, oil tankers, petroleum and chemical plants, and petroleum tank farms. Gas detection monitoring apparatuses are used with the enclosure which will automatically simultaneously shutdown one or more enclosures.

Abstract: One or more enclosures constructed about one or more objects at which hot work is to be performed at a facility containing flammable and/or combustible material. Hot work includes such things as welding, torch cutting, grinding and the like that produces heat, spark, slag or flame. The one or more enclosures are capable of being simultaneously and independently controlled and monitored by a single control and monitoring system.
