Heat stress may occur to human when the controlling means for internal temperature to their body starts to fail (Health and Safety Executive, 2013). There are different contributing factors to the heat stress such as temperature, amount of work performed in heat (ambient temperature), clothing worn at work and humidity. When somebody wears protective dress to perform heavy task in hot environment, can result the heat stress due to: restricting the evaporation of sweating; heat rise in body due to amount of work and loss of insufficient heat; dehydrations can cause due to deep body temperature rises within the body reacts through increase in sweating rate; increase in heart rate which adds the strain on human body; ultimately it reaches a point

While other side, the effects of heat stress on human associated with cognitive abilities are not recognized fully. Though, it is very necessary to focus on the effects of the thermal environment on human cognitive performance for many substantial motives. Firstly, the WHO states that a good human health consists on well-being of mental, physical and social. The understanding of cognitive performance in a better way under the heat stress and a consideration on state of mental well-being of workers can significantly use to define the occupational exposure limit for working in heat and it can also help in improving the quality of life in public and occupational workplaces. Secondly, a strong connection has been found between heat stress and unsafe behavior by workers. It was found that unsafe behavior of worker in a manufacturer industry and a foundry was negligible (within the acceptable range of 17-238C WBGT), but major increase (up to 358C WBGT) in unsafe acts was found in hot weather conditions, Ramsey et al. In view of these figures, it should be required to emphasis on assessing the cognitive and psychomotor aptitudes of the employees. Thirdly, these days, the complications in the industrial and military areas have increased that imposed the increasing of mental workload on operators, which may lead to human errors. Due to these explanations, many …show more content…
The rate of metabolic heat for every worker is measured, whenever the environmental heat is measured and screening assessment of metabolic heat exceeds the standard RAL or REL (Appendix 1 and Appendix 2). There different methods used to measure the production of metabolic heat such as indirect open-circuit procedure, indirect close-circuit procedure etc. The units for metabolic heat rates are used kilocalories per hour (kcal/h), British thermal units (Btu) per hour, or watts (w) for a 1-hour TWA job basis, that includes all tasks performed during every period of assessment, and all scheduled and non-scheduled rest durations.
5. Prevention of Heat Illness
The identification of hazards involves recognizing the heat hazards and associated risks of illness from high temperature, humid conditions, exposure to sun and thermal heat, workloads, personal clothing or personal protective equipment and other risk factors to personnel (OSHA Factsheet, 2014)
OSHA states that workers exposure to heat can cause illness and death. The heat stroke is a most serious illness occurs due to heat (OSHA, 2014), while other occurrences such as heat cramps, heat rashes and heat exhaustion should also be prevented. Such precautions should be taken by an employer whenever temperature reached at the level of risks associated to heat stress:
a. Develop a program for heat illness prevention.
b. Provide training to workers about the hazards of heat stress and preventive measures.
c. Enough cool
