Precautions In Qualitative Research

If the room is too hot this could make the service user feel sleepy or if the room is too cold the service user may not want to stay in the room and go somewhere else.

Air Quality: this section applies to dust and emissions/pollutants related to construction and operational traffic.

The number of people in the room, contributing to the humidity, is one of the contributing factors to the change in percentages of oxygen.The condensation of a person’s exhaled breath is a factor that also minimally contributes to the humidity in the atmosphere. Humidity is the amount of water vapor in the air at any given moment. When a person exhales, it marginally impacts the relative humidity, and, due to common sense, if there is more people in the room, there is a greater level of humidity. The percentage of oxygen in dry air is 20.95%. However, the air is not always dry. Thus, the percentage of oxygen cannot always be the same if humidity is always changing. Furthermore, dew point temperature is the absolute measure of the amount of water vapor present in the air. So, if the temperature is higher, it can hold more water vapor, making warmer climates much more humid than cooler climates. So, the temperature in the room is also an indirect contributing factor to the percentage of oxygen in the air. The distance above sea level is thought to potentially affect the percentages of oxygen. Nonetheless, it has been established that the percentage of oxygen molecules is always the same when considering altitude. This is because air is compressible, so the weight of all the air above applies pressure to the air at that particular altitude, making that air at

odour which means you need to ensure you have adequate ventilation in place such as an open

Ideally, a comprehensive heat stress program will include several elements, including environmental and medical monitoring (i.e., measurements of pulse rate, oral temperature, and/or weight loss) (OSHA, 1993). Sites also lacked verbal warnings of potential heat stress hazards nor crew rest areas, which endangers personal wellbeing. The heat stress protocols of the organization all varied inconsistently and did not entail a comprehensive program. Between the five superfund incinerator sites multiple citations were issued, thus accumulating to thousands in fines. The citations ranged in severity; from improperly secured high-voltage boxes (Citation 1910.305(b),(g)) to inadequately grounded or bonded drums used to transfer flammable liquids (Citation 1910.106) (OSHA, 1993). Supervisors must implement on-going self-assessment programs that monitor and evaluate employee health and skills. Regular assessment is imperative to ensure employees are aware of their surroundings and adhere to

Air pollution has been recognized as a major threat to environmental health, and the effects that it can have on the population are extremely varied. In the environmental aspects, air

When in doubt, contact your local indoor air quality specialist. The CDC website lists contact information by state, and provides links to other valuable resources, including the National Association of Clean Air Agencies (NACAA).

Scenario: A property developer is converting an old railway station into retail and office accommodation. The client is keen to make the working environment for the staff as comfortable as possible. As a consultant, explain how this can be done by addressing the relevant grading criteria.

CH₂ heating and cooling system is designed to have a temperature of 21-23°C. It works with a combination of ceiling panels and chilled beams which can be found above the windows. These beams create cool air at around 18°C. Heat is absorbed in the concrete ceilings and through the natural ventilation of the building will be removed. As approximately 70% of the ceiling is curved in shape, there is expected to be a 14% decrease in cooling energy usage by the natural ventilation process. Figure 1 show’s how the cooling of the offices is expected to work.

Dan and his contractor decided upon adding insulation, sealing up ducts and gaps in his walls, and replacing his 20-year old furnace with an energy efficient one. Dan felt the results immediately – he was finally comfortable in his home.

We all appreciate having good health. However, in our current society, we have so much air pollution. This affects our health greatly, that why you need good quality indoors air systems. Which will ensure that the quality of the air you take in is of high quality? We offer a range of services that are aimed at ensuring that you and your family get the best quality of air. Our services include:

This memo proposes the observations and claims I collected from reviewing three different lab reports. Three fields of study are composed within this memo that includes Electrical Engineering, Environmental Engineering, and Petroleum Engineering. “Electrical Filters,” (Electrical), written by Joe Schmoe, is a lab report made by a student at a university. The College Board produced an environmental lab report named, “Monitoring Air Quality,” (Air), for the purpose of student education as a lab template. Monitoring Air Quality was written by Dr.

The experiment took place in the D5 school classroom at Rangiora High School. This particular classroom had artificial lighting although there were windows around the classroom we shut the curtains. Due to poor heating /temperature controlling systems in the classroom and the amount of people in the room at the time, the temperature was above room temperature ( 20 degrees celsius) meant the temperature was hot, stuffy and very uncomfortable. Furniture was of average comfort, but there was limited space which meant one of pods was faced the opposite way to the other 7 pods, we were also in close proximity of one another. It was nature of this proximity and number of people in the one room, that caused high noise levels at the beginning until
