The information provided is largely based on 

the booklet, LZ 

 Preparing the Landing Zone, issued 

by National Emergency Medical Services Pilots 
Association (NEMSPA), and the guidance developed 
by the University of Tennessee Medical Center’s 
LIFESTAR program, and is used with their 
permission. For additional information, go to 

http://www.nemspa.org/

c. 

Information concerning the estimation of wind 

velocity is based on the Beaufort Scale. See 

http://www.spc.noaa.gov/faq/tornado/beaufort.html 

for more information. 

d.  Selecting a Scene LZ 

1. 

If the situation requires the use of a helicopter, 

first check to see if there is an area large enough to 
land a helicopter safely.

ing are provided as examples of relative helicopter 
size: 

(a) 

Small Helicopter:  Bell 206/407, Euro-

3. 

The LZ should be level, firm and free of loose 

debris that could possibly blow up into the rotor 
system. 

4. 

The LZ should be clear of people, vehicles 

and obstructions such as trees, poles and wires. 
Remember that wires are difficult to see from the air. 
The LZ must also be free of stumps, brush, post and 
large rocks. See FIG 10

Landing Zone Hazards 

5. 

Keep spectators back at least 200 feet. Keep 

emergency vehicles 100 feet away and have fire 
equipment (if available) standing by. Ground 
personnel should wear eye protection, if available, 
during landing and takeoff operations.  To avoid loose 
objects being blown around in the LZ, hats should be 
removed; if helmets are worn, chin straps must be 
securely fastened. 

6. 

Fire fighters (if available) should wet down 

the LZ if it is extremely dusty.
