Chemical Hazards Handbook: Ventilation
Contents Search publications Previous Next From: Chemical Hazards Handbook Section: 4 Prevention and control of chemical hazards - Controls - Ventilation There are several types of ventilation systems, including natural ventilation, general mechanical ventilation and local exhaust ventilation. Natural ventilation, such as simply opening doors and windows, should never be relied on to control exposure to chemicals, as several case studies in this book show.

Local Ventilation 05
Local supply air systems have been used successfully for workstation applications such as weighing, bag-filling, mixing, soldering and other stationary work functions. If the same technique is applied to operations involving movement, many clean air devices are needed and this results in high investment and operating costs.

Lung growth and aging Table of contents Introduction What you will learn Growth of lung volume Isometric lung growth Changing body proportions Form and function The lung and gas exchange Elastic properties of lung and thorax Lung elasticity and age Lung elasticity, thorax and age Thorax form and function Airway and lung parenchyma Uneven ventilation Airway closure Neonate exhales incompletely FRC and airway closure Isometric lung growth? Check-valve mechanism Conditions for isometric growth Flow regimes Longitudinal study Isometric lung growth in asthma Isometric lung growth in health Permanent damage ? Conclusions Uneven alveolar ventilation Let us regard the lung as a spring that we fix at its top end. The top end carries the full weight and is hence distended. The extent to which it is stretched depends on the spring's weight and its stiffness. Lower parts of the spring carry a progressively smaller portion of the load, and will therefore be stretched less. In terms of the lung this implies that the highest parts of the lung (where they are anatomically located depends on body posture) are subjected to a greater distending force, and therefore have a greater volume per alveolus, than lower parts. By implication pleural pressure decreases from top to basal parts of the lung. This has been confirmed experimentally; also the fact that the pressure gradient can be abolished in weightlessness, and be inverted by having a subject stand on his head, confirms that it is due to gravitational forces acting on the lung. If all alveolar units have identical pressure-volume characteristics, then compartments in the top will be more extended (greater volume V) than basal lung compartments.
Garage Ventilation Exhaust ventilation from garages or workshops Sponsored Links In a garage or workshop where exhaust gases like Carbon Monoxide (CO) and NO x from vehicles are very dangerous, proper ventilation of the area is very important. Garages or workshops with floor areas more than 500 ft 2 (50m 2 ) should always have mechanical ventilation with fans. Smaller garages can have natural ventilation with evacuation of air through ducts with larger area than 0.2% of the floor area. Required Air Changes per Hour As a general rule of thumb the minimum
