The provision of airbase rescue equipment, if required by local authority, should be provided in a crash box protecting all components from the elements.
Inspection schedules of the equipment should be formulated and periodic inspections docu-mented.
Examples of the required equipment can be found in CAP 437 for helidecks, and ICAO Annex 14 for airports, airstrips, heliports and helidecks.
11.7 Airbase fire protection & equipment
All airbases should have a means of extinguishing a fire that is commensurate with the potential risk.
Inspection schedules of the equipment should be formulated in accordance with the manufacturer’s recommendations or local regulations. Periodic inspections should be documented.
Examples of the required equipment can be found in CAP 437 for helidecks; ICAO Annex 14 for airports, airstrips, heliports and helidecks; and The National Fire Protection Association “NFPA 418 Standard for Heliports”.
The following guidelines are presented as a minimum and are in accord with NFPA 418. Local regulations may differ. Airbases should comply with local regulatory requirements, but in absence of regulatory requirements, the following criteria apply:
a) Flammable liquid storage tanks should be located at least 16 meters from the takeoff and landing area.
b) Landing areas should be sloped to drain flammables and liquids away from passenger access and egress points.
c) No smoking is allowed on airbases, other than in designated locations.
d) Portable fire extinguishers may be used on unmanned airbases or areas when water is not available.
e) At least one portable fire extinguisher as specified in the following table should be provided for each landing area, parking area, and fuel storage area, and the equipment should be tagged with the last inspection date.
Minimum Ratings of Portable Fire Extinguishers for Heliports:
Category
Helicopter overall length, including both rotors
Minimum rating
H-1
Up to but not including 15.2 meters (50 feet)
4-A:80-B
H-2
From 15.2 meters up to, but not including 24.4 meters (50 - 80 feet)
10-A:120-B
f) Foam/Water Systems: For long term use/manned facilities a Water/Foam system is desir-able that will provide fire protection to the landing/parking area. Industry tests indicate that 1% foam induction systems have frequent failures of finished foam concentrate levels, and 3% foam induction systems are preferred for new build or major rework.
––These systems should be tested in accordance with NFPA 11 or British Standard 5306 or local national equivalent.
––Tests should be completed on an annual basis with samples taken from the foam concen-trate, produced (after nozzle finished) foam, and water.
––Copies of testing results will be maintained for review.
