Storage and Handling
Store AeroTech rocket motors in a dry place where the temperature will remain
between 45
0
F and 100
0
F. Do not cut, saw, attempt to alter the size, attempt to
disassemble, attempt to modify, or drop an AeroTech rocket motor. Do not use an
AeroTech rocket motor that you believe has been damaged in any way. Do not ignite an
AeroTech rocket motor indoors. Do not breathe fumes from the rocket motor exhaust.
First Aid
For a minor burn, apply a burn ointment. For a severe burn, immerse the burned area in
ice water at once and see a physician as quickly as possible. In the unlikely event of
oral ingestion of the propellant, induce vomiting and see a physician as quickly as
possible. The composite propellant used in AeroTech rocket motors consists primarily
of Ammonium Perchlorate and a rubber-like plastic elastomer. Redline™ propellant
also contains Strontium Nitrate.
Disposal
Pack motor firmly in hole in ground so that only the nozzle is exposed, in a remote area
away from people, animals, buildings and flammable materials. Ignite motor electrically
from a distance of 50 feet or more. Propellant and smoke charge will burn until
consumed.
Wait 5 minutes
and then dispose of the motor casing in inert trash.
Fire Safety
AeroTech composite rocket motors will normally not ignite unless subjected to direct
flame. Use water to fight any fires in which AeroTech rocket motors may become
involved: Direct the water at the AeroTech rocket motors to keep them below their 550
deg. F autoignition temperature. Foam and carbon dioxide fire extinguishers will NOT
extinguish burning propellants of the type used in AeroTech rocket motors. Keep rocket
motors away from flames, sources of heat and flammable materials.
