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.
