NFPA 418:2016

Provide fire protection and life safety in heliports with essential provisions only in NFPA 418: Standard for Heliports.
A unique tool for fire protection and life safety, NFPA 418: Standard for Heliports establishes minimum fire safety requirements for operation at heliports for the protection of people, aircraft, and other property. Engineers, designers, contractors, and installers need these vital requirements to ensure a minimum level of safety in all types of heliports or helipads, including in hospitals, airports, offshore platforms, and tourist attractions.
The Standard is also essential for code officials and facility managers -- such as in hospital settings where additions or modifications could dramatically impact the safety of patients and health care or aircraft personnel. The fire service relies on NFPA 418 for pre-incident planning, with provisions concerning fire-fighting access points, egress routes, and fixed fire protection systems, as well as aircraft refueling equipment.
