How can you improve indoor air quality in healthcare settings?

2 Implement a cleaning and disinfection protocol

The second step to improve IAQ in healthcare settings is to implement a cleaning and disinfection protocol that follows the guidelines and standards of the industry and the regulatory agencies. A cleaning and disinfection protocol is a set of procedures and practices that aim to remove dirt, dust, and debris from the surfaces and equipment, and to kill or inactivate harmful microorganisms that can cause infections. You should use appropriate cleaning products and disinfectants that are compatible with the materials and devices, and that have a low impact on the IAQ. You should also train and educate the ES staff on how to use the products and equipment safely and effectively, and how to protect themselves from exposure.

3 Optimize the ventilation system

The third step to improve IAQ in healthcare settings is to optimize the ventilation system that provides fresh and filtered air to the indoor spaces. A ventilation system is composed of fans, ducts, filters, dampers, and controls that regulate the air flow, pressure, and quality. You should inspect and maintain the ventilation system regularly to ensure that it operates properly and efficiently, and that it meets the requirements of the different areas and functions of the facility. You should also replace or clean the filters frequently to prevent the accumulation of dust and contaminants. You should also adjust the ventilation rates and settings according to the occupancy, activity, and season.

4 Control the temperature and humidity

The fourth step to improve IAQ in healthcare settings is to control the temperature and humidity levels that affect the comfort and health of the people and the equipment. Temperature and humidity are interrelated factors that influence the evaporation, condensation, and growth of moisture and microorganisms. You should maintain the temperature and humidity within the recommended ranges for the different zones and functions of the facility, such as patient rooms, operating rooms, laboratories, and storage areas. You should also monitor and prevent the occurrence of hot or cold spots, drafts, or leaks that can create thermal discomfort or damage the materials and devices.

5 Reduce the sources of emissions

The fifth step to improve IAQ in healthcare settings is to reduce the sources of emissions that release harmful or unpleasant substances into the indoor air. These can include the use of chemicals, solvents, paints, adhesives, pesticides, and fragrances that can emit VOCs or odors; the combustion of fuels, tobacco, or candles that can produce smoke, carbon monoxide, or nitrogen oxides; and the generation of waste, such as medical, biological, or hazardous waste that can attract pests, rodents, or insects. You should minimize the use of these sources, or replace them with safer or greener alternatives. You should also store, handle, and dispose of them properly and securely, and follow the regulations and protocols for their management.

6 Educate and communicate with the stakeholders

The sixth and final step to improve IAQ in healthcare settings is to educate and communicate with the stakeholders, such as the management, the staff, the patients, and the visitors, about the importance and benefits of IAQ. You should inform them about the IAQ policies and procedures, and the roles and responsibilities of each party. You should also encourage them to participate and cooperate in the IAQ improvement efforts, such as reporting any problems or concerns, following the hygiene and safety rules, and providing feedback and suggestions. You should also recognize and reward the best practices and achievements of the ES staff and the other stakeholders, and celebrate the positive outcomes and impacts of the IAQ improvement initiatives.
