Abstract

Purpose

The purpose of this paper is to investigate the incremental impact of firefighter’s personal protective equipment (PPE) on lower body range of motion (ROM) while walking to suggest areas of design improvement for enhanced mobility and safety.

Design/methodology/approach

Eight male and four female firefighters participated in the study. Lower body ROM was assessed while they walked in four different configurations of PPE, including turnout ensemble, a self-contained breathing apparatus (SCBA) and boots. The impact of each added PPE item, and gender differences were statistically analyzed.

Findings

Wearing firefighter turnout ensemble and SCBA reduced ROM in the lower body in the sagittal and transverse planes. A significant reduction in ROM for anterior-posterior movement at the ankle and the ball of the foot was found while wearing rubber boots with turnout ensemble and SCBA. This puts firefighters at higher risk of experiencing foot injuries and physical strains. A significant increase in medial-lateral movement of the foot while wearing rubber boots may increase risk of ankle sprains. A greater reduction in ROM at the ankle and the ball of the foot for female firefighters may imply greater risk for women compared to men, while wearing boots.

Practical implications

Reducing the inflexibility and bulkiness of boots is critical to improve firefighter’s lower body mobility and safety.

Originality/value

This study implemented 3-D motion capture technology to analyze how wearing firefighting gear impacted lower body motion. It provides quantitative evidence to recommend ergonomic boot re-design.

Abstract

Purpose

This study aims to examine how the role of peripheral knowledge changes along with the perspectives of vendor and client in inter-organizational IT outsourcing. To this end, this study tests the effects of the peripheral knowledge of vendors and clients on IT outsourcing performance under three different combinations of performance-assessing views from both parties.

Design/methodology/approach

To contrast the effects of the peripheral knowledge of vendors and clients based on their views, this study collects matching data on 107 projects from both parties. The survey method is adopted to measure the peripheral knowledge levels of vendors and clients and IT outsourcing success. The associations between peripheral knowledge and IT outsourcing performance are then assessed when the views match, cross and agree to a certain level.

Findings

The peripheral knowledge of vendors plays a more significant role than that of clients in most IT outsourcing cases. Moreover, the agreement between the peripheral knowledge of vendors and clients shows a moderating effect only when the performance is assessed by clients than by vendors.

Originality/value

This study contrasts the peripheral knowledge of vendors and clients by altering performance-assessing views in IT outsourcing. This study also rationalizes why the peripheral knowledge of vendors is more important than that of clients, as well as explains whose perspective is more significant when the performance is assessed.
