HERO susceptible ordnance systems are any ordnance
systems proven (by tests) to contain EED that can
be adversely affected by RF energy to the point that the
safety and/or reliability of the system is in jeopardy
when the system is employed in expected RF environments.
Some systems are susceptible to the RF environment
for only a small part of the stockpile-to-launch
sequenceF. or example, the connectiono f an umbilical
cable in the loading procedure may be the only time the
system is considered susceptible. At all other times in
the system’s life, it may be considered HERO safe ordnance.
HERO safe ordnance are any ordnance suffrciently
shielded or protected that all EED contained by
the item are immune to adverse effects that degrade
safety or reliability when employed in its expected RF
environment (provided that general HERO requirements
have been complied with).
3.2.2.3 Fuel Ignition Hazard. When performing
fueling or defueling operations, use minimum safe distances
outside of radiation hazard areas. Fuel ignition
hazard occurs within 90 feet of the aircraft where RF
radiation induced sparks could ignite flammable vapors
of fuels. Fuel ignition hazard is based on SW/cm* peak
power density.
Good housekeeping operations are of utmost importance
in areas where radar transmission is anticipated.
RF radiation may cause steelwool to be set afire or
metallic chips to-produce sparks, which in turn may
ignite spilled fuels or oils around aircraft and buildings.
