 S 842-014-C00
 (4)  
High temperature exhaust can be found 300 feet from the exhaust nozzle with the correct wind conditions.

 (a)  
The exhaust temperature near the engine is sufficient to melt bituminous (asphalt) pavement.

 (b)  
Concrete pavement is recommended.

 S 842-015-C00
 (5)  
When an engine is started, fuel that has collected in the turbine exhaust sleeve can ignite.

 (b)  
All flammable materials must be kept clear of the exhaust nozzle.

 S 842-016-C00
 (6)  
There are gases in the exhaust that are dangerous to you.

 (a)  
Tests have shown that the amount of carbon monoxide in the exhaust is small.

 (b)  
There are other gases in the exhaust that smell bad and can cause injury or irritation to your eyes and lungs. 1) These gases will usually cause a watering or burning

 sensation to your eyes. 2) Less noticeable, but important, is the respiratory irritation.

 (c)  
You must stay away from small spaces where these gases can collect.
