Evaluation of Fall Arrest Harness Sizing Schemes
نویسندگان
چکیده
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. METHOD 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. CONCLUSION 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. APPLICATION This research could help reduce the risk of worker injury resulting from poor fit, improper size selection, or failure to don the harness properly.

Physis or "Growth plate" is responsible for Longitudinal and latitudinal growth of bones, during growth period of life. Trumatic lesions of the physis may have disturbancing effect on the growing bone. These lesions can result complete or partial growth arrest and shortten-ing or angular deformity of the bone.Trumatic lesion of the Physis is very common in male than female, and they are 15 to 2...
متن کاملThe influence of anchor devices on the performance of retractable type fall arresters protecting against falls from a height.
Retractable type fall arresters are part of the equipment used for protecting people against falls from a height. They are an intermediate part between full body harness worn by a man and the structural anchor at the worksite. The most important task of retractable type fall arresters is to arrest people's falls and to reduce their harmful consequences. Information received from users as well a...
متن کاملPattern of injury after rock-climbing falls is not determined by harness type.
OBJECTIVE Experimental data indicate that when using a sit harness alone, any major fall during rock climbing may cause life-threatening thoraco-lumbar hyperextension trauma or "head down position" during suspension. To clarify the actual influence of the type of harness on the pattern and severity of injury, accidents involving a major fall in a climbing harness were analyzed retrospectively. ...
متن کاملMandatory, preferred, or discretionary: how the classification of domestic violence warrantless arrest laws impacts their estimated effects on intimate partner homicide.
Warrantless arrest laws for domestic violence (DV) are generally classified as discretionary, preferred, or mandatory, based on the level of power accorded to police in deciding whether to arrest. However, there is a lack of consensus in the literature regarding how each state's law should be categorized. Using three classification schemes, this study examined whether variations among these sch...
