BACKGROUND In hot weather, overweight and obesity are considered as significant risk factors for the incidence of cardiac strain in workers. This study was aimed to compare cardiac strain among overweight and normal-weight workers in hot, humid conditions in the south of Iran. METHODS This cross-sectional study was conducted on 71 workers in the south of Iran in summer 2010. The heart rate wa...

OBJECTIVES The purpose of this study is to evaluate the tire manufacturing work environments extensively and to identify workers' exposure to hazardous substances in various work processes. METHODS Personal air sampling was conducted to measure polycyclic aromatic hydrocarbons, carbon disulfide, 1,3-butadiene, styrene, methyl isobutyl ketone, methylcyclohexane, formaldehyde, sulfur dioxide, a...

OBJECTIVE To determine the effect of exposure to metal dusts, fumes and high temperature levels among brass workers in comparison to a control group. STUDY DESIGN Analytical cross-sectional study. METHODOLOGY One hundred and fifty four brass workers were matched for age with 154 controls selected from the local population. An interviewer-administered questionnaire was used to determine the ...

In cool conditions, physiologic markers accurately predict endurance performance, but it is unclear whether thermal strain and perceived thermal strain modify the strength of these relationships. This study examined the relationships between traditional determinants of endurance performance and time to complete a 5-km time trial in the heat. Seventeen club runners completed graded exercise test...

The purpose of this study was to examine the heat stress effects of three protective clothing ensembles: (1) protective apron over cloth coveralls including full face negative pressure respirator (APRON); (2) the apron over cloth coveralls with respirator plus protective pants (APRON+PANTS); and (3) protective coveralls over cloth coveralls with respirator (PROTECTIVE COVERALLS). In addition, t...

The purpose of this study is to provide industry practitioners with a better understanding of the impacts of high-temperature conditions on construction labor productivity. Such information could assist in the establishment of plans to prevent heat-stress injuries and help improve the safety and comfort of construction labor working environments. On-site WBGT (Wet Bulb Globe Temperature) data a...
