Mayo Clinic leads the way in waste reduction and environmentally sustainable firefighting practices
In a significant move toward enhancing safety, sustainability and environmental stewardship, Mayo Clinic has completed a groundbreaking initiative to reduce waste and substitute the use of aqueous film-forming foam in its firefighting systems. Aqueous film-forming foam, traditionally used for its effectiveness in suppressing flammable liquid fires, contains perfluorooctanesulfonic acid (PFOS), a chemical known for its persistence in the environment and potential health risks. This multidisciplinary effort included teams from Facilities, Sustainability, Safety, Viking Sprinkler and Mayo Clinic Waste Management, among others.
The problem with PFOS
PFOS is part of a larger group of chemicals known as per- and polyfluoroalkyl substances (PFAS), often referred to as "forever chemicals" due to their resistance to breaking down in the environment. These substances have been linked to various health issues, including cancer, liver damage, and immune system effects.
The widespread use of PFOS in firefighting foams has raised significant environmental and health concerns, prompting organizations worldwide to seek safer alternatives. PFAS substances are found in common products such as non-stick frying pans, water and oil-resistant clothing, food packaging, and fabric protective sprays.
Mayo Clinic's commitment to sustainability
Recognizing the urgent need to address these concerns, Mayo Clinic completed a comprehensive waste reduction program that includes the phasing out of aqueous film-forming foam. This initiative is part of Mayo Clinic's broader commitment to sustainability and environmental responsibility.
By eliminating PFOS-containing foams, Mayo Clinic aims to protect both its patients and the surrounding community from potential exposure to harmful chemicals. The Baldwin Building, Franklin Heating Station, Charlton helipad and the Saint Marys Mary Brigh helipad were among the locations that switched to safer alternatives.
Implementing safer alternatives
Mayo Clinic is transitioning to either a water-only system or environmentally friendly firefighting foams that do not contain PFOS or other harmful PFAS chemicals. These new foams are designed to provide the same level of fire suppression effectiveness without the associated environmental and health risks. The switch to safer alternatives is a monumental step forward in ensuring that firefighting practices align with modern safety and sustainability standards.
Benefits of the initiative include:
Enhanced safety: By removing PFOS from its firefighting systems, Mayo Clinic significantly reduces the risk of chemical exposure to patients, staff and first responders.
Environmental protection: The transition to PFOS-free foams helps prevent soil and water contamination, contributing to a healthier environment and community.
Sustainability leadership: Mayo Clinic's proactive approach sets a benchmark for other healthcare institutions, demonstrating that it is possible to maintain high safety standards while prioritizing environmental health.
Disposal
Disposal of PFAS chemicals is a challenge for the waste industry. High-temperature combustion or incineration has shown to effectively destroy 99.9999% of the perfluoro-compounds. As part of the system transition, over 2,000 gallons of aqueous film-forming foam and rinse from the systems were disposed via incineration through Mayo's contracted hazardous waste vendor.
A monumental time for change
This initiative marks a monumental time for Mayo Clinic, reflecting its dedication to pioneering practices that safeguard both human health and the environment. As the healthcare industry continues to evolve, Mayo Clinic's efforts in waste reduction and the substitution of harmful chemicals in firefighting foams serve as an inspiring example of how institutions can lead the way in sustainability.
By prioritizing safety and sustainability, Mayo Clinic not only enhances its operational practices but also reinforces its commitment to the well-being of the community and the planet. This forward-thinking approach ensures that Mayo Clinic remains at the forefront of healthcare innovation, setting a standard for others to follow in the pursuit of a safer, more sustainable future.
