Calculation of Contaminant Concentrations While Coating the Interior of a Bulk Storage Fuel Tank.

摘要

In the last decade we, as a society, have made great strides in the field of Occupational Safety and Health. The smarter we become about the hazards that surround us the more we need to learn. It is not enough to know that a substance provides a potential risk to an individual but we need to know what that risk is; specifically in a particular occupational activity, when does exposure to a chemical become hazardous and what are the effects if the exposure. Air quality may be defined as the characteristics of air that affect an individual's health and well-being in a salubrious way. More technically, air quality is a quantitative indicator of how well air satisfies the requirements for human occupancy: thermal acceptability; normal concentrations of respiratory gases (i.e., oxygen, nitrogen and carbon dioxide); and suppression of other contaminants below levels that are deleterious to health or produce unpleasant odors.
