3M 7100141833 Ear Canal Sizing Tool

Product Description

The 3M 7100141833 is an ear canal sizing tool designed to provide a general indication of the size of the ear canal opening, used as a guide for initial earplug size selection. Commonly referred to as an Ear Gage, this instrument helps safety professionals and occupational health technicians match workers to the correct earplug size before fit testing or hearing protection program enrollment. Accurate sizing at the point of initial issuance reduces improper fit, which is a leading cause of reduced hearing protection effectiveness in industrial and commercial environments.

This tool is suited for use in occupational safety programs, industrial hygiene assessments, and hearing conservation programs across manufacturing, construction, and other high-noise environments. Safety managers, occupational health nurses, and industrial hygienists typically use this tool during worker onboarding or annual hearing protection evaluations to streamline earplug size assignment.
