Indoor Air Quality for Healthcare Facilities​


Higgins’ experienced industrial hygienists are available to assist with potential indoor air quality problems, providing effective solutions following Occupational Safety and Health Administration (OSHA), Environmental Protection Agency (EPA), National Institute for Occupational Safety and Health (NIOSH) and American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) guidelines. We offer guidance and practical solutions to health problems associated with indoor air quality issues in industry, healthcare and construction.
