Human Factors is the study of how the capabilities and limitations of people shape the ways in which they interact with and use products, equipment, and systems in their environments. It is an essential assessment and evaluation tool in a wide range of complex accidents involving commercial trucking, automobiles, railroads, aviation, utilities, construction, mining, oil and gas, chemical process, manufacturing, medical devices, consumer and commercial products, and premises liability issues.

Environmental contamination, releases, and chemical exposures impacting the environment and people’s health have unfortunately become quite prevalent. Rimkus engineers, geologists, industrial hygienists, toxicologists, and other environmental professionals are called upon to assess the extent of the environmental impacts, health risks, and associated costs to remediate damages and determine exposures.
