Field Evaluations

product testing safety field evaluations

Responsive, efficient and affordable on-site testing and evaluation to keep your project moving forward.


The Occupational Safety and Health Administration (OSHA) requires that all electrical equipment be certified, listed, and labeled by an approved laboratory. When an unlisted product is installed, building inspectors may not approve the installation.

In these situations, you are left with two choices. You can replace the unlisted product with a listed one, or you can have the unlisted equipment safety tested and labeled in the field.

Field evaluations are typically less expensive, less labor intensive, and quicker to complete than direct equipment replacements. Therefore, Field Evaluations are often the best option.
