What Is Indoor Air Quality Course?
MARCOM’s Indoor Air Quality course is an interactive online training program that discusses the health hazards associated with contaminated indoor air, the most common contaminants and where they come from, and what employees can do to help keep the air in their workplace clean and healthy.
Contaminated indoor air is currently one of the top five threats to public health, according to the Environmental Protection Agency (EPA). Any hazardous fumes, dusts, bacteria, or spores that people inhale can result in them feeling unwell, interfere with their ability to work efficiently, and even lead to serious health problems.
Areas covered in the course include information on the symptoms of poor air quality, heating, ventilation and air conditioning systems, sources of air contamination, what people in a building can do to improve the air quality, and more. The course uses a combination of audio, full-motion video, text, and colorful graphics. It is divided into logical sections so information is easily understood and retained. The course is 100% online, self-paced, and accessible on desktop, tablet, and mobile devices.
