Ergonomic evaluation of protective clothing for earthquake disaster search and rescue team members

Purpose: The ergonomic performance of protective clothing for earthquake disaster search and rescue team members is significant for its protective performance.
Design/methodology/approach: By experimental simulations of the rescue tasks, an evaluation system for the protective clothing in both static and dynamic conditions was designed and established in this study. In static evaluation, motion capture system was used to measure the ranges of motions. The mobility was analyzed by the comprehensive evaluation method. In dynamic experiments, three types of rescue tasks were simulated for ergonomic evaluation. The results were analyzed based on the multi-levels joint evaluation method.
Findings: It was shown that the established evaluation system could meet well with the requirements of the ergonomic evaluation.
Originality/value: Fuzzy comprehensive evaluation method is an effective tool in ergonomic evaluation of clothing. The newly designed coverall and suit are of better ergonomic performance compared with the in-service clothing.

Systèmes d'ancrage pour la protection contre les chutes

Ce guide se veut un outil d'information pour les employeurs de la construction qui auront à fabriquer, à installer ou à utiliser des systèmes d'ancrage pour la protection contre les chutes conformes à la nouvelle règlementation du Code de sécurité pour les travaux de construction (RLRQ, chap. S-2.1, r.4).?

Explorations of Design Factors for Developments of Protective Gardening Gloves

The purpose of this study was to identify important design factors for protective gardening gloves and consider possible design features for these gloves. A mixed methods procedure was used involving market research, an online survey, and a focus group. Ten design factors of protective gardening gloves were identified: skin cut and puncture protection, dirt and insect protection, UV ray protection, water resistance/waterproofness, dexterity, comfort of movement, breathability, ease of donning and doffing, durability, and ease of care. Potential consumers' preferred design features for each design factor were investigated through the online survey and focus group. Designers can apply the identified preferred design features in this study as guidelines to satisfy each design factor so that designs can be more easily accepted by consumers. The results of this research can be beneficial for designers in the development process of protective gardening gloves and ultimately benefit gardeners.

Principles and hierarchy design of protective clothing for earthquake disaster search and rescue team members

Purpose: Personal protective assembles protect searchers and rescuers from potential hazards when they enter the earthquake disaster field. Since the earthquake rescue work is risky and complicated, the corresponding protective clothing should meet with the protective, functional and comfort performance demands. The purpose of this paper is to discuss the design principles of this kind of protective clothing and present a design model based on the principles.
Design/methodology/approach: In this study, the requirements of the protective clothing were investigated in terms of environment, human and clothing. Then the design principles were analyzed by the hierarchy method in four aspects: protection, comfort, ergonomics and compatibility. Design approaches were also investigated in accordance with the design principles in three hierarchies.
Findings: Key design points were summarized in the selection of the shell fabrics and linings, clothing styles, constructions and specifications. Also, the overall design methodology of the protective clothing for earthquake rescue members was established.
Originality/value: This paper provided a theoretical basis and design model for the development of earthquake search and rescuers' clothing.

Étude sur le vieillissement, la dégradation et la durée de vie des équipements de protection contre les chutes - cordes d’assurance

Ce projet porte sur l'effet des expositions prolongées aux intempéries sur les propriétés de certaines cordes d'assurance verticales, notamment sur leur résistance mécanique. Sept types de cordes ont été étudiés : kernmantle, multiline, polyamide, polyester, polyéthylène, polypropylène et polysteelMD. Les cordes ont été soumises au vieillissement accéléré en chambre environnementale en laboratoire et au vieillissement naturel statique (soleil et intempéries, mais sans utilisation). Au bout de 6, 12, 18 et 24 mois d'exposition naturelle, des essais de caractérisation mécanique et physico-chimique ont été effectués afin de suivre l'évolution des propriétés des cordes. Le but ultime de ce projet est de construire un modèle validé expérimentalement (équation logistique) pour extrapoler la résistance du matériau en fonction de la durée d'exposition environnementale.
