Pictured here is a “Platform Operator Shed” widely known and used in the petrochemical industry. Normally the booth is mounted high above an operation either on a platform or a walkway and used for observations or to operate a system. These booths are constructed complete with explosion proof electrical. The most commonly requested classification would be Class I, Division II, Group D. These sheds can be as small as 3′ x 4′ or as large as needed and most common would be 4′ x 6′ or 6′ x 8′.
The most common accessories requested with these are: incandescent light with wall switch, single receptacle, 1700w heater with thermostat, and 14,000 BTU through wall air conditioner. When one of these units leave the factory all the electrical accessories are installed and piped to a single explosion proof junction box. Once on site, the final power supply connection and completion of the seal-offs are completed by the owner.
