Abstract

A video inspection system for hazardous environments is provided, comprising a housing, sealable so as to contain a pressurized gas therein, having a view opening therein and further including a valve for introducing pressurized gas into the housing, connected to the housing; and a transparent lens, sealingly affixed across the view opening; a camera for recording visual images through the view opening, mounted within the housing; and a power supply, for powering the camera, mounted within the housing and operatively connected to the camera. A method for operating the above system is also provided, including the steps of substantially purging undesirable gases from the interior of the housing; sealing the housing, eliminating external connections thereto; introducing non-flammable gas to the interior of the housing until the pressure in the housing reaches a desired level; and operating the camera within the housing. The system may also be operated as a portable lighting system without the camera and may utilize fiber optics communications to transmit contemporaneous signals from the camera in a hazardous environment.
