Abstract
Consequences of thermal induced radiation from ovens on the physiology of Bakery workers in Calabar, was investigated. An in-situ measurement approach to estimate the impact of thermal radiation on human physiological changes. The relationships between the measured temperature parameters were correlated with a questionnaire inventory. Statistical analysis of the questionnaires based on the relevant hypotheses was carried out. The results show that, the P-values of 0.005; 0.001; 0.006; 0.001 and 0.001 less than 0.05 in all cases and was prevalent. The statistical result implies that there is a significant effect of thermal radiation emanating from bakery ovens on the physiology of workers as this was used to establish the wellbeing of workers in the perceived heat stressed environment. It also was found out that the exposure of workers to thermal radiation in all the bakeries under study exceeded the WHO (20oC- 29oC) exposure limit for comfort. All the bakeries visited during this study used firewood industrial oven.
Highlights
Thermal radiation generated in most work places as a result of hike in temperature especially from bakery ovens is seen to pose both environmental and health related threats to both man and animals
The objective of this paper is to evaluate the consequences of thermal induced radiation on the physiology of bakery workers in Calabar, Cross River State, Nigeria
A questionnaire based on the hypotheses, there is no significant effect of thermally induced radiation from bakery ovens on it workers was generated with items skewed to health related problems and was issued to workers of the selected six ovens in Calabar south
Summary
Thermal radiation generated in most work places as a result of hike in temperature especially from bakery ovens is seen to pose both environmental and health related threats to both man and animals. Studies by Beheshti et al, (2016) reveals that thermal stress due to heat is caused by both internal and external thermal factors which have an overriding effect on human fatigue and development of disease condition He opined that environmental heat influences the performance and productivity of humans through changing physiological parameters, such as blood flow and hormonal release rate. He observed that there is an unbalanced regulatory mechanism in human body when the temperature reaches threshold value, tissue damage and/or alterations of biological processes may occur. The objective of this paper is to evaluate the consequences of thermal induced radiation on the physiology of bakery workers in Calabar, Cross River State, Nigeria
