Self Reported Symptoms Due To Heat Stress Among Housekeeping Workers Of A Residential Complex Maintenance Sector
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2015, Vol 3, Issue 6
Abstract
Abstract: Linkages between thermal loads and its physiological consequences have been studied in organized sector settings of developed countries. Outdoor workplace settings in developing countries are largely influenced by radiation from direct sunlight that may contribute to greater than recommended levels of heat exposure. Consequently a wide range of health implications can cause unsafe conditions and thermal discomfort leading to reduced performance in hot working temperatures. This study is aimed to evaluate the perception of housekeeping workers regarding heat stress and also assess the self reported symptoms due to heat stress. The objective of present study is to assess self –reported health symptoms and perceptions of housekeeping workers of a residential complex maintenance sector in relation to occupational heat stress. Heat stress was assessed through Environmental measurements (WBGT). A standardized questionnaire was administered to 40 workers to assess a range of symptoms due to exposure to heat stress. The questionnaire also recorded productivity loss in terms of missed work hours/days or sickness/absenteeism. WBGT levels in the residential sector ranged from 27.6 to 32.4 oC. Nearly 80% of the workers reported excessive sweating suggestive of exhaustion and fatigue. 20% reported symptoms of severe exhaustion, while 33% reported skin rashes. Amongst women workers 20% reported urinary tract infections and/or burning sensations. 15% of workers also reported loss of productivity (in terms of not being able to finish assigned work in the given time) that they perceived to be due to heat exposures. The worker perceptions have indicated that occupational heat stress exposure resulting from outdoor work is likely to have implications for health and productivity. Further assessments to refine this relationship warrant quantitative assessments of physiological responses. These studies will help in implementing effective interventions and protective policies. Keywords: thermal loads, Heat stress, physiological responses, health implications.
