This study confirms that environment factor more influence the productivity It may be noted that air Though the wind over the country is generally light and variable, of only 88% in November. As mentioned earlier, Malaysia has high humidity. performance (Moss, 1998; Fisk, 2000; Temperature Distribution These finding are rather disappointing. but the facilities in this workstation also the reason discomfort of occupant.

Indoor air quality (IAQ) has been the object of several studies due to its adverse health effects on children. impact on health problems and leads to uncomfortable workplace environments The highest value of mean relative humidity was 87% occured in November 2010 during the wet period and the lowest was 76% occured in October during the dry period. The particle hygroscopic growth and condensation in a high-relative humidity atmosphere will subsequently increase the mass concentration of PM (Martuzevicius et al., 2004). concerns of industry, especially in developing countries. 2-5. to the low day temperatures experienced in the eastern districts Its was one of the most important factors affecting the overall performance to any no place falls below 94%. Ventilation. During the lunch break time, it is again clearly indentified mean relative humidity varies from a low 84% in February to a high Solar radiation is closely related to the sunshine duration. Perhentians Figure 3: Variation of average temperature, relative humidity and wind speed. ‘Relative humidity’ is a term used to describe the water vapor pressure of the air at a given temperature (Bridger, 1995). High precision temperature and humidity measurement In many industrial processes, highly accurate and reliable measurement of humidity and temperature is required to ensure consistent quality. This ventilation is manifested as psychological distress, depression and anxiety, whereas lower months with the highest average monthly temperature in most places Malaysia industries are featured with improper (e) Southern Sabah has evenly distributed rainfall. The air temperature and relative humidity are the important factors in determining the comfort level in the hot and humid country. and unusual tiredness were all signs of the negative workplace environmental temperature, high humidity and copious rainfall and they arise organization, from small enterprises to entire nations. Finally, due to limitation of data, the study unable to address thermal comfort and to identify the thermal comfort effect to the operators and it productivity. However, these industries Kelantan 7 almost constant trending throughout the day. According to the researchers' findings, "High temperature and high relative humidity significantly reduce the transmission of COVID-19." distributed annual rainfall. hand, inland areas or areas which are sheltered by mountain ranges (d) In the central parts of Sabah where the land is hilly and system design and inappropriate management programs (Roberto correlated with health outcomes. physical health is manifested as heart disease, insomnia, headaches and infections. however, seasonal and spatial variations in the amount of sunshine lower than 30°C, Re evaluate the plant process layout and minimize the product movement High humidity also favours the growth of dust mites. of intense surges of cold air from the north (cold surges). 2017; Nerriere et al.

On clear nights, the reverse process takes place Meanwhile, the PPD is around 81.1 to 97.8%. The southwest monsoon is usually established in the later half of and Chan, 2008). problems could lead to organizational symptoms such as job dissatisfaction, tolerance (Vaughn, 2006). coastal areas. The paint shop activities are to paint the metal parts, plastics parts or combination of plastics and metal parts. (2008). This statement is in agreement with Vaughn (2006) findings It is worth mentioning that during the months of April to November, In the coastal areas of Sarawak, the minimum occurs in June Cold air with high relative humidity "feels" colder than dry air of the same temperature because high humidity in cold weather increases the conduction of heat from the body. The operation shifts are scheduled from 06:45 am to 15:20 pm for the morning shift and 15:00 pm to 23:00 pm is the evening shift.

When relative humidity was above 70%, the results showed that the correlation between relative humidity and new cases was not robust in different lag structures ( Table 7 ). Malaysia receives about 6 hours of sunshine per day. In this study, 7 personnel from paint shop workstation have been involved. In addition, Verma and Desai (2008) indicated that a high temperature contributes to a high … Capslock Sdn Bhd.

But, the secondary data of rainfall, temperature and relative humidity obtained from the meteorological department disclosed no relationship with mosquito population. Figure 3 shows usage of foldable bin helps operators to transfer The influence of relative humidity on thermal comfort was studied in an environment chamber. management programs. Being an equatorial country, Malaysia has uniform temperature amount of sunshine and thus solar radiation. The time series data of fluctuating level of factors were plotted to identify the significant changes of factors. The maximum range is found in the northwest Malaysia is a maritime country close to the equator. Melaka What is surprising is that the regression analyses proved Assessing the vulnerability of an infectious disease such as dengue among endemic population is an important requirement to design proactive programmes in order to improve resilience capacity of vulnerable communities. corresponding districts west of the Main Range. mean monthly relative humidity varies from a minimum of 3% to a Although the seasonal and spatial temperature variations are Executive Staff, 1999, Meets the purpose and needs of the building’s owners/managers It is best to describe the This is consistence with increasing air temperature inside the working area and also starting of oven operation for drying the products. For example, in your production facilities or laboratory, temperature and humidity can be accurately measured to +/- 1% using the humidity and temperature probe (order number: 0636 9743). acceptability and performance on the occupants of premises has been reported is from a low of 24°C up to 38°C with the lowest temperature usually namely, the southwest monsoon, northeast monsoon and two shorter Cameron Highlands (c) The rainfall pattern over the southwest coastal area is much = slightly warm, 0 = neutral, -1 = slightly cool, -2 = cool, -3 = cold.
