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.

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.

Safety in the storage and handling of steel and other metal stock

Many accidents, some resulting in death and serious injury, continue to occur during the storage and handling of steel and other metal stock. They cause enormous social and economic cost over and above the human tragedy involved. It is in everyone's interest that they are reduced. Accident investigations often show that these injuries could have been avoided.
This revised guidance is aimed at directors, owners, managers and supervisors and pays particular attention to the most common hazards, including (un)loading of delivery vehicles, storage systems, workplace transport, mechanical lifting and injuries from sharp edges.

Évaluation de l’efficacité d'un filtre N95 contre des particules ultrafines, dont les nanoparticules, en mode de débits d'air constant et cyclique simulant la respiration des travailleurs

On trouve des particules ultrafines (PUF), soit des particules dont le diamètre (Dp) est inférieur à 100 nm, dans de nombreux milieux de travail industriels, où leur inhalation peut, à long terme, causer de graves problèmes de santé. Dans certains contextes, les mesures d'ingénierie et les contrôles administratifs sont insuffisants pour protéger adéquatement les travailleurs contre l'exposition aux PUF. Un dispositif de protection personnel est alors requis, et les appareils de protection respiratoire à pièce faciale filtrante (APR) de type N95 sont ceux qu'utilisent le plus couramment les travailleurs de l'industrie et de la santé.

Evaluation method for thermal protection of firefighters’ clothing in high-temperature and high-humidity condition

A review
Purpose: To provide researchers with the details of developments in test apparatus and evaluation methods to rate the thermal protective performance (TPP) of firefighters' clothing under high-temperature and high-humidity condition.
Design/methodology/approach: This review paper describes the influence laws of moisture on thermal protection and the moisture distribution in actual fire environment. Different evaluation methods used for assessing the effect of moisture on the TPP were investigated, with an emphasis on test devices, evaluation indexes as well as their relationship and limitations.
Findings: The moisture from the ambient, clothing and human perspiration plays an important role in determining the TPP of firefighter protective clothing. It is obvious that research on moisture-driven heat transfer in firefighter's clothing system are comparatively little, primarily focusing on pre-wetted methods of multi-layer fabric. Further studies should be conducted to develop more standardized moistening systems and improve the current calculation methods for evaluating the performance of protective clothing. New explorations for heat and moisture transfer mechanism in protective clothing should be investigated.
Practical implications: Protective clothing is the efficient way to provide firefighting occupational safety. To accurately evaluate the TPP of protective clothing under high-temperature and high-humidity condition will help to optimize the clothing performance and choose the proper clothing for providing firefighters with the best protection under multiple thermal hazards.
Originality/value: This paper is offered as a concise reference for scientific community further research in the area of the TPP evaluation methods under high-temperature and high-humidity condition.

EPI et vêtements de travail : mieux comprendre leurs caractéristiques antistatiques pour prévenir les risques d'explosion

L'évaluation du risque d'explosion implique la prise en compte des vêtements de travail et équipements de protection individuelle en tant que sources d'inflammation potentielle de l'atmosphère explosive dans laquelle ces équipements peuvent se trouver. À la suite des constats présentés dans l'article ND 2358, des travaux ont été menés afin de valider les paramètres de la " méthode du mannequin " permettant la caractérisation des propriétés antistatiques de ces équipements. Lors de ces travaux, il a notamment été mis en évidence que le mode de charge par influence des équipements n'est pas à négliger, car il est fréquemment rencontré sur le lieu de travail et est à l'origine de la génération de quantités élevées de charges. Par la suite, cette méthode a été utilisée afin de caractériser l'influence du vêtement porté sous l'équipement sur la capacité de ce dernier à écouler les charges électrostatiques. Il en ressort que la nature et l'épaisseur des vêtements portés sous l'équipement ont une influence importante, notamment que les matières dissipatrices (type coton) sont à privilégier.

Are health care personnel trained in correct use of personal protective equipment?

Effective use of personal protective equipment (PPE) is essential to protect personnel and patients in health care settings. However, in a survey of 222 health care personnel, PPE training was often suboptimal with no requirement for demonstration of proficiency. Fourteen percent of physicians reported no previous training in use of PPE.

Comparison of two quantitative fit-test methods using N95 filtering facepiece respirators

Current regulations require annual fit testing before an employee can wear a respirator during work activities. The goal of this research is to determine whether respirator fit measured with two TSI Portacount instruments simultaneously sampling ambient particle concentrations inside and outside of the respirator facepiece is similar to fit measured during an ambient aerosol condensation nuclei counter quantitative fit test.
Sixteen subjects (ten female; six male) were recruited for a range of facial sizes. Each subject donned an N95 filtering facepiece respirator, completed two fit tests in random order (ambient aerosol condensation nuclei counter quantitative fit test and two-instrument real-time fit test) without removing or adjusting the respirator between tests. Fit tests were compared using Spearman's rank correlation coefficients.
The real-time two-instrument method fit factors were similar to those measured with the single-instrument quantitative fit test. The first four exercises were highly correlated (r > 0.7) between the two protocols. Respirator fit was altered during the talking or grimace exercise, both of which involve facial movements that could dislodge the facepiece.
Our analyses suggest that the new real-time two-instrument methodology can be used in future studies to evaluate fit before and during work activities.

PPE-Info Database

How do you know if your personal protective equipment (PPE) will protect you or your workers? To help employers, users of PPE, and others determine which PPE standards must be met by their equipment, NIOSH in collaboration with key partners including the International Safety Equipment Association, the Occupational Safety and Health Administration, the Mine Safety and Health Administration and other members of the PPE Conformity Assessment Working Group developed the PPE-INFO database.
