Indoor Air Quality, Part I provides a list of questions to help you determine if poor indoor air quality (IAQ) might be a problem in your workplace. If it is a problem and you’ve seen your doctor, consider the following steps for improving the IAQ of your workplace.
Tips for Improving Indoor Air Quality
OSHA states that while it does not have standards in place that employers must follow for IAQ, employers are required to “follow the General Duty Clause of OSHA, which requires them to provide workers with a safe workplace that does not have any known hazards that cause or are likely to cause death or serious injury.”
Within the General Duty Clause, employers should be aware of hazards detrimental to employees’ health. OSHA further states that “the qualities of good IAQ should include comfortable temperature and humidity, adequate supply of fresh outdoor air, and control of pollutants from inside and outside of the building.”
The Environmental Protection Agency says there are 3 basic strategies for improving IAQ.
- Source Control. This involves eliminating individual sources of pollution or reducing their emissions. This can be as simple as storing food and disposing of garbage properly. It can also mean avoiding using items that aren’t necessary, and that could be potentially harmful. Source control also involves putting “scraper” mats by doors to eliminate contaminants on people’s shoes and mopping floors regularly.
- Ventilation. Increasing the fresh airflow and ensuring the ventilation within a building is not restricted by furniture and equipment. Good IAQ also involves paying attention to a building’s heating, ventilation, and HVAC systems. Routine inspections and cleaning of these systems reduce the buildup of irritants.
- Air cleaners. Replacing filters regularly is essential for air cleaners to work properly to maintain good IAQ. HEPA filters can also be used on vacuums to help eliminate allergens. Another tip is keeping dehumidifiers and air conditioners at the optimal range for keeping allergens at bay. And sometimes, wearing a particle respirator might be in an employee’s best interest to prevent inhaling harmful dust, fumes, vapors, and gas.
Every situation is different
While the above tips provide ideas to consider when looking at a building’s IAQ, remember that every situation is different. Therefore, each business should develop an IAQ policy to suit the unique needs of its situation.
Another consideration is that even though we’ve become more environmentally conscious, IAQ has not necessarily improved. Dr. Philip Landrigan, the Dean for Global Health at Mount Sinai of Medicine in New York, says this is because “business buildings today are sealed much tighter to keep interior air cooler in the summer and warmer in the winter. The downside is that this can also lock in contaminants. The basic lesson for every health-minded person is to keep attuned to the quality of the air you breathe “no matter the season.”
