Product Safety

Warnings, Signage, and Safety Instructions


Warnings, signage, and safety instructions are an integral part of product design, process design, and safe use of equipment. The development of an adequate system requires determining when a warning is needed, what an adequate warning system would be, and if the warning is effective, by involving numerous product specific variables. From novice to expert users, trained employees, installers, and maintenance staff, the development and evaluation of warnings must consider the intended use for the operator and environment(s).


Fusion human factors and ergonomics provides industrial consultation and litigation support for safety signage, labels, instructions, manuals, product documentation, and roadway work zones. Expertise in ANSI Z535 and other relevant standards are utilized to explain how individuals perceive hazards, respond to warnings, and safety information.  Factors such as color, placement, symbology, verbiage, and format are assessed with respect to accident causation.

Failure Mode and Effect Analysis

Failure mode and effect analysis is a step-by-step approach used to thoroughly identify and prioritize all possible failures within a product or process. Failures are prioritized based on the severity of the outcome, likelihood they will occur, and ability to be detected. The purpose of a failure mode and effects analysis is to eliminate or mitigate the risk associated with the use of a product. Fusion Human Factors and Ergonomics provides guidance, reviews, and training on the FMEA process.
