Abstract

Project paper (B.S.(Environmental & Occupational Health)) – Universiti Putra Malaysia, 2015. Introduction: Traffic policemen involved working in hot environmental condition with high temperature during their working hour. However, there is a less of study on the exposure of heat stress among the policemen who using motorcycle as their transport during working process. Objectives: The purpose of this study is to determine the physiological changes and heat related illness in heat stress among traffic policemen in Kuala Lumpur. Methods: This cross-sectional study was conducted among traffic policemen in Kuala Lumpur. Traffic policemen (n=55) were interviewed using self-constructed questionnaire. Interviews based on questionnaires is used to determine respondent's socioeconomic background, medical history and job description. Heat stress assessment of relative humidity and temperature will be measured using EL-USB-2-LCD Humidity, Temperature and Dew Point Data Logger with LCD. Meanwhile, Omron MC-510 Gentle Temperature Ear Thermometer (measure core body temperature), POLAR Heart Rate FT60 (measure heart rate) and OMRON T3 Automatic Blood Pressure Monitor (measure blood pressure) will be used in the physiological measurement of the traffic policemen. This instrument is wearing by traffic policemen in Kuala Lumpur personally. This instrument is place on traffic policemen for eight hours. Results and Discussion: The results highlighted that all the traffic policemen in Kuala Lumpur were not exceeded Threshold Limit Value (TLV) (<28°C).Dehydration (89.1 %) is the highest prevalence of heat related illness reported, followed by heat exhaustion (80.0%), heat cramps (29.1%), heat syncope (25.5%), heat rashes (1 8.2%) and heat stroke (12.7%). The value of WBGT out has strong correlation with the relative humidity reading (r = 0.76, p <0.001).There was significant differences in physiological parameters (body core temperature, F (1.93, 104.05) =33.19, p<0.001; heart rate, F (1.28, 106.30) - 3.71, p< ,001); systolic blood pressure (F (1.90, 129.539) =1.912, p<0.001) and diastolic blood pressure F(l.92. 103.71) =3.094, p<0.001) between three session. Conclusion: Traffic policemen are low exposed to heat stress due to their working environment. The highest prevalence of heat related illness among traffic policemen is dehydration. There is significant difference in physiological parameters between three different sessions which indicates the traffic policemen are subjected of exposure heat stress during the first two hours before the acclimatization process happens. Keywords: Heat stress, heat related illness, traffic policemen, physiological parameters
