Video work

Overview The U.S. Air Force has classified material that must be destroyed. Disintegrators provide an alternative to incineration for the destruction of classified materials. Disintegrators are able to handle the destruction of paper, thick documents, video cassettes, microfilm or reels, CD-ROMs, microfiche, and diskettes. Disintegrators are available with a capacity of 50 to over 7500 lbs. per hour. Disintegrators work in the following way ... 

Typically, visitors have little or no reason to enter exclusion zones. An observation deck or other area out of the exclusion zone can usually allow any visitor (with or without the aid of binoculars) to observe work activities as necessary. Video cameras have been used successfully to show... 

CADD, a part of CAD, is the computer-assisted generation of working drawings and other documents. The CADD user generates graphics by interactive communication with the computer. The graphics are displayed on a video terminal and can be converted into hard copy by a printer or plotter. 

Where such internal inspection work is carried, out a safety checklist and processes for confined space entry permit system and tag-out/lock-out MUST be undertaken before any person enters the boiler. The inspection of waterside surfaces should be carried out by a suitable qualified person and will benefit from employing either an instant camera or a video camera (Horoscope or similar fiberoptic-based device) to record any parts of the boiler where corrective action is needed. 

An industrial microscope with a long-working distance 20 X objective is used for the collection of the chromatic interference patterns. They are produced by the recombination of the light beams reflected at both the glass/chromium layer and lubricant/steel ball interfaces. The contact is illuminated through the objective using an episcopic microscope illuminator with a fiber optic light source. The secondary beam splitter inserted between the microscope illuminator and an eyepiece tube enables the simultaneous use of a color video camera and a fiber optic spectrometer. 

These batteries are much cheaper to make than earlier nickel battery types, and have an energy density almost double that of lead-acid. NiMH batteries can accept three times as many charge cycles as lead-acid, and work better in cold weather. NiMH batteries have proven effective in laptop computers, cellular phones, and video cameras. 

Such systems can generally recognize fires of 34,000 BTU/hr (lOkW) or greater at 33 ft (10 m) within a 90°cone of vision, and are immune to common false alarms such as hot CO2 emissions, reflections from flare radiation, black body radiation, and hot work. An added benefit is that the video image can be recorded for later analysis. 

Flash units and motor drives are potential ignition sources. In many cases, a gas test and hot work permit will be required before using a flash unit, motor drive, or video camera. Each specific use of flash devices may require authorization. Infrared gas detectors may also be set off by flash units. When using a flash even with permission, it is a good practice to take the time to warn and alert all personnel who could see the flash (or a reflection of the flash). This will preset...
