Definition - What does Air Pollution mean?
Air pollution refers to the introduction of a harmful or poisonous substance into the air. Harmful gases and particulate pollution are concerns in both the outdoor and indoor environments. These pollutants can cause illness and even death as well as having impacts on the environment beyond the workplace.
Depending on the industry, OSHA requires regular monitoring and measurement of pollutants relevant to that industry or workplace. Since pollutants tend to accumulate in indoor spaces, indoor air quality (IAQ) is of particular importance in any indoor workplace or public space. Specific air quality standards and measurement criteria are stipulated by OSHA.
Safeopedia explains Air Pollution
Apart from pollutants produced by industrial processes that affect atmospheric air quality, indoor areas are particularly susceptible to contamination with gasses and particles from office equipment as well as pollutants released from carpeting, furniture and the development of molds and other microbes in air conditioning systems, within ceiling spaces and in basements. Outdoor pollutants that enter buildings also persist for longer periods owing to the re-circulation of air and poor ventilation.
Outdoor pollution affects industrial and construction workers as well as the environment in general, so certain industries must monitor their emissions diligently, maintaining them at levels that are deemed safe for workers and the environment as a whole.
