Indoor Air Quality
Indoor air quality, Ventilation is the process of bringing outside air into a building, moving it around the room, and removing stagnant air in order to improve the quality of the indoor air. This can be achieved by natural means, mechanical means, or both. The term indoor air quality (IAQ) describes the air inside buildings and structures. It can be contaminated by radon, molds, pet dander, chemicals from household items, volatile organic compounds (VOCs), smoking particulate matter, and bugs, all of which can have a negative impact on one’s health.
INDOOR AIR QUALITY
The usage of specific home furniture and items, high temperatures, elevated humidity, and inadequate ventilation are some of the main variables influencing indoor air quality.
Chemicals that cause indoor air pollution can be found in paints, cleaning supplies, furniture, and construction materials. Dust, smoke, and aerosols are examples of particulate matter that can enter the lungs through the nose and lungs.
Types of Ventilation
Natural Ventilation;
INDOOR AIR QUALITY
is a method of bringing outside air into a structure without the use of fans or other mechanical devices. This involves ventilation through the building’s windows, doors, roof turrets, and other openings.
Mechanical ventilation;
INDOOR AIR QUALITY
defines the process of using powered devices, such as fans, to transport air into or out of a structure. The outside air may require filtering or cleaning before it reaches the building, depending on where it comes from. The supply and extraction theory states that while a second set of ducts takes the stale air and exhausts it outside, the first set of ducts and inlet grilles bring outside air into a space. Diffusers for incoming air can be found on the floor, on the wall, or in the ceiling.
Local exhaust ventilation;
INDOOR AIR QUALITY
is an engineering system intended to transfer pollutants to a safe emission point or a filter/scrubber from the source of the contaminants ( dust, mist, fume, vapour,gas). There isn’t any general ventilation for it.
How to improve ventilation;
While it is difficult to reduce the needs for ventilation to a single, easy to follow method. The kind of ventilation, the duration of exposure, the nature of the building and its user, and the occupational activities being carried out must all be taken into consideration when designing specialized safety measures. Nonetheless, there are useful methods to enhance your ventilation
Natural ventilation can be improved by;
INDOOR AIR QUALITY
1) Whenever feasible, open doors, windows, and vents, especially in between tasks or users, to enhance the quantity of fresh air without compromising the comfort employees.
2) Avoid closing doors or windows completely when people are in a naturally ventilated area
3) “air rooms” as much as you can. It might be ideal to do this at breaks, at the start and end of the day, or while the room is empty.
Summary
Inadequate IAQ affects comfort, health, and well-being by exacerbating infections, allergies, cardiovascular disorders, and respiratory disorders. Effects on the Nervous System and Cardiovascular System: Higher risk of heart attacks, strokes, and blood clots.
