Task 1 (p1)
Describe the following factors that influence human comfort in the internal environment.
• Temperature
Extreme air temperatures, either hot or cold can put physiological stress on an individual. This lack of control in a workplace, such as large open plan office can lead to job dissatisfaction and increased incidence of stress or even sickness. This will cause an increase in officer absentees and a decrease of morale and productivity. Radiant temperature has a greater influence than air temperature on our ability to lose or gain heat in our environment. Therefore working in conditions of direct sunlight and hot machinery could meant the workforce struggle to work efficiently even when the air temperature is within a suitable and normal working range.
• Humidity
Humidity is caused when water is heated and evaporates into our surrounding environment. It is this level of water in the air that is the level of humidity. Relative humidity is the ratio between the amount of water vapour actually in the air and the maximum amount the air can hold at that given temperature. High humi environments cause humans problems because the high water content decreases the amount of sweat that is evaporated from our skin. Low humidity can cause our skin, sinuses and eyes issues because of the increase rate of evaporation. It can lead to our skin becoming dry, our eyes to become itchy and irritated sinuses.
• Light
Different brightness’s are required for different activities. Ideally it is important to be able to control the level of light and tailor it to the task, including both natural and artificial sources. More precise work will need a higher level ofht either in the room or on the object that you may be working on, such as soldering, or electrician works. Whereas an office with mainly desk, pc workers may not need the room so bright, and may become uncomfortable if exposed to much light for too long, especially considering pc screens also emit...
