Cleanroom environments are controlled work areas that are designed to protect products from contamination. Cleanrooms are an integral part of organizations, manufacturing high-end products like silicon chips, hard drives, satellites etc. Organizations spend millions of dollars to build and maintain cleanrooms in order to ensure safety of manufacturing equipment and deliver high quality products. A significant amount of this investment goes into the procurement of equipment such as chairs, stools, desks, etc. Improper selection of this equipment has the potential to ruin the clean environment, and this could have disastrous financial implications.

Effective contamination control is achieved by imposing strict regulations that govern sterile cleanroom work environments and demand a very high level of compliance. This places extreme requirements on furniture, which is used to outfit such work spaces. The Business and Institutional Furniture Manufacturer's Association (BIFMA) and American National Standards Institute (ANSI) have developed benchmarking standards for such equipment. These standards are widely accepted.

People and equipment are major sources of contaminants in any controlled environment. In one likely scenario, a worker might touch a piece of furniture during the workday. Contaminants such as chloride, silicon, etc. present on this furniture might easily make their way to the products being produced, resulting in manufacturing defects and low yield.

ESD (electrostatic dissipation) is used in conjunction with cleanroom designed chairs in clean environments where both static charges and contamination particles are a major concern. The ability of ESD chairs to dissipate electrostatic charge to the ground plays a critical part in maintaining a sterile environment. Resistance to Ground (RTG) and Decay Time (DT) are used to measure electrostatic dissipation.

ESD/Cleanroom chairs are widely used in industries such as semiconductor chip fabrication, aerospace, pharmaceuticals, biomedical sciences, computers, medical equipment, and many more. As it falls under the category of industrial seating, it should be designed for maximum comfort and productivity. To accomplish this goal, ESD/Cleanroom chairs incorporate the principles of ergonomics. A typical ESD/Cleanroom chair should be engineered to provide the following features:

 

  • It should be manufactured using fabric and components capable of dissipating electrostatic charge.
  • It must comply with BIFMA and ANSI standards.
  • It should be built for heavy duty use.
  • It must be ergonomically designed.
  • It should have a lumbar back support.
  • It should be easy to use, and be equipped with pneumatic height adjustment.

 

ESD/Cleanroom chairs provide the ultimate blend of electrostatic dissipation, cleanroom performance and enhanced user comfort.
