Objective: This study provides an assessment of heat stress in indoor rice vermicelli manufacturing factories.
Methods: Worker interviews and heat stress assessments were conducted in food manufacturing factories in Singapore. The Wet Bulb Globe Temperature (WBGT) and Heat Stress Index (HSI) were used as heat stress indicators.
Introduction: This study aimed to determine if disposable filtering facepiece respirators (FFRs) that come with an exhalation valve (EV) and a novel active venting system (AVS) provided greater perceived comfort and exertion when compared to standard N95 FFRs without these features among male military personnel performing prolonged essential outdoor duties.
Methods: We used a randomised open-label controlled crossover study design to compare three FFR options: (a) standard FFR; (b) FFR with EV; and (c) FFR with EV+AVS. Male military personnel aged between 18 and 20 years completed a questionnaire at the start of outdoor duty (baseline), after two hours of standardised non-strenuous outdoor duty and after 12 hours of duty divided into two-hour work-rest cycles.
Introduction: Structured training for the prevention of needlestick injuries (NSIs) among medical students was implemented in Singapore in 1998. In this study, we determined the incidence of NSIs and the knowledge and practice of managing and reporting NSIs among first-year clinical students in a medical school in Singapore, as well as the adequacy of the training provided for these students, 14 years after preventive training was instituted.
Methods: All third-year medical students (n = 257) from the Yong Loo Lin School of Medicine, National University of Singapore, Singapore, who had completed their first clinical year posting were enrolled in this cross-sectional study.
