The National Fire Protection Association (NFPA) 99 is a code that sets vital health care safety regulations for the protection of patients, staff, and the general public within health care facilities. It addresses various areas, including requirements for the design of HVAC systems. Specifically, paragraph 9.3.1.1 of NFPA 99 mandates compliance with ASHRAE Standard 170 – Ventilation of Healthcare facilities, formally referred to as ANSI/ASHRAE/ASHE Standard 170.
The Facility Guidelines Institute (FGI) is responsible for formulating comprehensive guidelines for the planning, design, and construction of hospitals, outpatient facilities, and residential health care and support facilities. To ensure a unified approach to health care facility planning, design, and construction, FGI guidelines incorporate and align with key safety and environmental health standards, including those defined by the NFPA 99 code and ANSI/ASHRAE/ASHE 170 standard.
