Occupational heat stress and its association with physiological parameter at a selected steel mill / Nur Shahida Shaharuddin

Shaharuddin, Nur Shahida (2018) Occupational heat stress and its association with physiological parameter at a selected steel mill / Nur Shahida Shaharuddin. [Student Project] (Unpublished)


Many workers are exposed to heat during their job either outsides or in hot indoor environments. Task that expose workers to the potential of getting heat stress are activities involving high humidity, high air temperatures, high radiant heat sources, direct physical contact with hot objects, or labour intensive activities such as metal casting industries. When there is heat stress forced on the human body, it causes heat strain which triggers physiological responses. The objective of this study is to determine heat exposure on steel mill workers and its effect on physiological parameters. Fifty two workers from the steel mill participated in this study. Their physiological parameters were measured before and after 8 hours of work and the ambient temperature was monitored throughout the 8 working hours. The results show half of the workstations had ambient temperature reading exceed the Action Limit and Threshold Limit Value by American Conference of Governmental Industrial Hygienist. Albeit there were increase in physiological parameters between before and after work, all of the values are still maintained under the normal range except for systolic pressure. There were no significant difference between physiological parameters before and after 8 hours of work only for body temperature and systolic pressure. The study also found that there was no correlation between the ambient temperature and the physiological parameters due to p-value is more than 0.05 (p>0.05). Although half of the workstation exposed workers to high heat, their physiological parameters were not affected, this might occurred due to the workers ability to acclimatize in hot environment because they have been employed for more than a year
