Heat stress on 500-660 mm pipe workers in oil rig jackets assembly welding works

摘要

The research is to study the problem related to the heat stress among workers at heavy industrial yard. Heat stress occurrence would cause several problems such as heat stroke, heat exhaustion, heat syncope, heat cramp and heat rash (Christopher et al. 2004). This condition could affect workers capability, health, perception and judgment in which it will reduces the efficiencies of work. The objective of the research is to show the time region that worker might suffer from heat stress, compared the heat stress before and after safety procedure been executed, showed the correlation between several factors that contributes to the heat stress among workers and proposed a better work practice to the industry management. The respondent of the research is a worker who was involved in working inside the pipe. This was carried out using the heat environment tools (QuesTemp34). The methodology of the research is based on observation in which the data was collected and plotted to find the correlation between factors that are significant to the heat stress occurrence. Other method used to support the data is by using a quantitative method such as questionnaire which contains a question related to the effect of heat stress, thermal comfort and bodywork physiology. Expected result from the research is to identify the factors for heat stress occurrence, the duration of time that is most high possibility of heat stress to occur and to compare the reduction of heat stress level between two different conditions which is with the safety applied and not applied.
