Evaluation of fall arrest harness sizing schemes.
OBJECTIVE
This paper evaluated harness sizing schemes and anthropometric criteria for harness design applications.


BACKGROUND
Updated harness sizing systems are needed to accommodate diverse populations in the current workforce.


METHODS
Three-dimensional torso scan data and human-harness interfaces from 108 women and 108 men were digitally captured. Abounding box approach was employed to quantify the effect of torso shape and size on fall harness fit.


RESULTS
A logistic regression model with eight equations was developed and tested to classify more than 96% of participants to the best-fitting size.


CONCLUSIONS
Study outcomes suggested an alternative system of two sizes for women and three sizes for men over the current four-size unisex system. In addition, thigh strap angle and back D ring location could be utilized along with current harness static fit test criteria to further enhance postfall harness fit predictions.


CONCLUSIONS
This research could help reduce the risk of worker injury resulting from poor fit, improper size selection, or failure to don the harness properly.
