At many work stations under cold environment, protective clothing, which is provided for the workers is characterized by an inadequate thermal insulation, which results in an adverse impact of cold environment on a worker's body. The purpose of this paper is to present a developed new ergonomic modular cold protective clothing, which allows for easy adaptation of the thermal insulation of clothing to worker's individual needs. This clothing was compared in a laboratory study with the clothing having been used so far by workers of cold environment using physiological and physical measurements, subjective ratings of thermal state as well a questionnaire of subjective assessment of used clothing...

The construction industry plays a significant role in contributing to the economy and development globally. During the process of construction, various hazards coupled with the unique nature of the industry contribute to high fatality rates. This review refers to previous published studies and related Malaysian legislation documents. Four main elements consisting of human, worksite, management and external elements which cause occupational accidents and illnesses were identified. External and management elements are the underlying causes contributing to occupational safety and health (OSH), while human and worksite elements are more apparent causes of occupational accidents and illnesses...

This research covers the current status of occupational health and safety (OHS)-related practices in the informal construction segment of Pakistan. Data were collected, through interviews, from 316 construction sites employing 3577 workers. The results of the study reveal that both employers and workers lack knowledge of OHS laws/standards and no practices of this nature are enacted at these construction sites. Alarmingly, work-related accidents, whenever they happen, are not given due attention and there is no formal injury-report system...

Purpose New light sources including light emitting diodes (LEDs) have elicited questions about retinal damage, including the blue-light hazard. Some organizations have recommended avoiding using LEDs with correlated color temperatures (CCTs) exceeding 3000 K, since they tend to produce greater short-wavelength energy. This paper provides quantitative comparisons among light sources and use cases as they affect blue-light hazard. Methods The spectral radiant power characteristics of incandescent, fluorescent, LED and daylight sources were evaluated in terms of blue-light hazard using standard procedures for phakic, aphakic and pseudophakic eyes...

Lin Zhou, Gui Fu, Yujingyang Xue
The human and organizational factors have been proved to be the prime causes for Chinese hazardous chemical accidents (HCAs). A modified version of the Human Factors Analysis and Classification System (HFACS), namely HFACS-Hazardous Chemicals (HC), was developed to identify the human factors involved in Chinese HCAs. The '8.12' Tianjin Port fire and explosion, the costliest HCA in recent years, was reanalyzed using this framework, and the results were compared with the official accident inquiry report to find out their differences related to the identification of human and organizational factors...

One of the most frequent manual occupational tasks involves the pushing and pulling of a cart. Although several studies have associated health risks to pushing and pulling, the effects are not clear since occupational tasks have social, cognitive, and physical components. The present work investigates a real case of a pushing and pulling occupational task from a manufacturing company. The study initially characterises the case in accordance with Standard No. ISO 11228-2:2007 as low risk. An experiment with 14 individuals during three modalities of pushing and pulling was performed in order to further investigate the task with the application of electrophysiology...

Unsafe behavior is a leading factor in accidents, and working environment significantly affects behaviors. However, few studies have focused on detailed mechanisms for addressing unsafe behaviors resulting from environmental constraints. This study aims to delineate these mechanisms using cognitive work analysis (CWA) for a case study of elevator installation. Elevator installation was selected for study because it involves operations at heights: falls from heights remain a major cause of construction worker mortality...
