For a severe burn, immerse the burned area in ice water at once and 3-2. Secure the igniter to the nozzle with a piece of masking see a physician as quickly as possible. In the unlikely event of tape or the 2-1/4" dia. red nozzle cap supplied with the oral ingestion of the propellant, induce vomiting and see a reload kit. NOTE: Cut a 1/8"-1/4" wide slot in the corner physician as quickly as possible. The AeroTech/RCS composite of the cap to allow for igniter venting. propellant consists primarily of Ammonium Perchlorate and a rubber-like plastic elastomer. 3-3. Install the motor into the rocket's motor mount tube. Ensure that the motor is securely retained in the rocket by using positive mechanical means to prevent it from Chapter 6. Disposal being ejected during recovery system deployment. Damaged or defective reload kits should be returned to RCS. 3-4. Prepare the rocket's recovery system and then launch the rocket in accordance with the Tripoli Rocketry Association (TRA) Safety Code and National Fire Protection Association (NFPA) Code 1127. Chapter 7. Fire Safety Chapter 4. Post-Recovery Cleanup NOTE: Perform motor clean-up as soon as possible after motor firing. Propellant and smoke charge residues become difficult to remove after 24 hours and can lead to corrosion of the metal parts. Place the spent motor components in the reload kit plastic bags and boxes and dispose of properly. 4-1. After the motor has cooled down, unthread and remove the forward and aft closures. Tests show that the pyrotechnic components of RMSTM reload kits will not explode in fires and normally will not ignite unless subjected to direct flame and then will burn slowly. Use water to fight any fires in which AeroTech/RCS RMSTM reload kit pyrotechnic components may become involved: Direct the water at the AeroTech/RCS RMSTM reload kit pyrotechnic components 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 RMSTM reload kit pyrotechnic components. Keep reload kit pyrotechnic components away from flames, sources of heat and flammable materials. 4-2. Remove the smoke charge insulator from the forward closure and discard. Using wet wipes or damp paper Disclaimer and Warranty towels, remove all smoke charge and propellant residues from the closures.
