3.13Emergency Situations
3.13.1In the event of a helicopter accident in the
vicinity of the LZ, consider the following:
3.13.1.1Emergency Exits:
a)Doors and emergency exits are typically
prominently marked. If possible, operators should
familiarize ground responders with the door system
on their helicopter in preparation for an emergency
event.
b)In the event of an accident during the LZ
operation, be cautious of hazards such as sharp and
jagged metal, plastic windows, glass, any rotating
components, such as the rotors, and fire sources, such
as the fuel tank(s) and the engine.
3.13.1.2Fire Suppression:
a)Helicopters used in HEMS operations are
usually powered by turboshaft engines, which use jet
fuel. Civil HEMS aircraft typically carry between 50
and 250 gallons of fuel, depending upon the size of
the helicopter, and planned flight duration, and the
fuel remaining after flying to the scene. Use water to
control heat and use foam over fuel to keep vapors
from ignition sources.

Multiple Helicopter Operations
4.1 Background. EMS helicopter operators often
overlap other EMS operator areas. Standardized
procedures can enhance the safety of operating
multiple helicopters to landing zones (LZs) and to
hospital heliports. Communication is the key to
successful operations and in maintaining organization
between helicopters, ground units and
communication centers. EMS helicopter operators
which operate in the same areas should establish joint
operating procedures and provide them to related
agencies.
4.2 Recommended Procedures.
4.2.1 Landing Zone Operations. The first helicopter
to arrive on−scene should establish
communications with the ground unit at least 10 NMs
from the LZ to receive a LZ briefing and to provide
ground control the number of helicopters that can be
expected. An attempt should be made to contact other
helicopters on 123.025 to pass on to them pertinent
LZ information and the ground unit’s frequency.
Subsequent helicopters arriving on scene should
establish communications on 123.025 at least 10
NMs from the LZ. After establishing contact on
123.025, they should contact the ground unit for
additional information. All helicopters should
monitor 123.025 at all times.
4.2.1.1 If the landing zone is not established by the
ground unit when the first helicopter arrives, then the
first helicopter should establish altitude and orbit
location requirements for the other arriving helicopters.
Recommended altitude separation between
helicopters is 500 feet (weather and airspace
permitting). Helicopters can orbit on cardinal
headings from the scene coordinates. (See
FIG ENR 6.2−9)
4.2.1.2 Upon landing in the LZ, the first helicopter
should update the other helicopters on the LZ
conditions, i.e., space, hazards and terrain.
4.2.1.3 Before initiating any helicopter movement to
leave the LZ, all operators should attempt to contact
other helicopters on 123.025, and state their position
and route of flight intentions for departing the LZ.
4.2.2 Hospital Operations. Because many
hospitals require landing permission and have
established procedures (frequencies to monitor,
primary and secondary routes for approaches and
departures, and orbiting areas if the heliport is
occupied) pilots should always receive a briefing
from the appropriate facility (communication center,
flight following, etc.) before proceeding to the
hospital.
4.2.2.1 In the event of multiple helicopters coming
into the hospital heliport, the helicopter nearest to the
heliport should contact other inbound helicopters on
123.025 and establish intentions. Follow the
guidelines established in the LZ operations.
4.2.2.2 To facilitate approach times, the pilot−in−
command of the helicopter occupying the hospital
heliport should advise any other operators whether
the patient will be off loaded with the rotor blades
turning or stopped, and the approximate time to do so.
4.2.2.3 Before making any helicopter movement to
leave the hospital heliport, all operators should
attempt to contact other helicopters on 123.025 and
state their position and route of flight intentions for
