Course Description:

The construction of a shielded room is quite different from other construction projects. It is a unique combination of carpentry, plumbing and electronic assembly procedures.

Many of the special techniques used in this type of construction are actually counter-intuitive: They are the opposite of what is done in normal construction. If these unique procedures are not carefully followed, the finished room may have several electronic leaks that can turn a profitable project into a financial disaster. Unlike with most trades, there are currently no formal training or apprenticeship programs for the people that assemble shielded rooms. This course is presented in a working electromagnetic laboratory. For its many practical examples and demonstrations, the course uses a 10 ft x 12 ft x 8 ft high 100 dB shielded room along with the instruments, tools and special components used in this field. This short, practical course fills a long-standing need in the shielding industry. It can save your organization many times its modest cost.

This course covers the unique procedures involved in building shielded rooms. It reviews a typical government testing standard, and provides a basic command of the terminology and concepts used in the shielding industry.
Participants will gain the ability to properly construct a shielded room under the direction of an experienced foreman or project engineer. They will also gain the ability to eliminate electronic leaks that have been pinpointed in a shielding effectiveness test. Participants will learn about the hazards to people and equipment that are involved in testing shielded rooms.

This course is specifically designed for the construction workers that assemble shielded rooms. Project engineers and construction foremen find that this course saves them both time and money, and reduces their risks. Anyone in government or industry whose responsibilities involve the construction, maintenance, or repair of shielded rooms can benefit.
