All rockets are safe when handled properly. You can design, build, and transport all rockets without any hazards.  All of the unsafe parts of launching a rocket are done out at FAR Site under the supervision of a state licensed pyrotechnic operator.  All launches are performed by remote control with all personnel in viewing bunkers or at a safe distance.

Bipropellant Rockets
Bipropellant rockets are safely transported with no fuel, oxidizer, or pressurants onboard. These rockets become progressively more unsafe when you: load fuel, load oxidizer, inserting the igniter, pressurize the pressurant tank, pressurize propellant tanks, ignite the igniter, and open the main propellant valves.   Launch preparations of loading fuel, loading oxidizer, and inserting the igniter are accomplished by key launch team members with the rocket on the launch rail and observers cleared of the launch pad.  All the remaining operations are performed with all personnel clear of the launch pad and in bunkers.  Hazardous operations like pressurizing pressurant and propellant tanks, igniting the igniter, and opening the main propellant valves are all done using remote commands.  DANGER, this type of rocket maybe susceptible to a BLEVE, depending on the type of propellants and tanks you use. (See the BLEVE Danger page.)

Hybrid Rockets
Hybrid rockets are safely transported with an inert fuel grain installed and no oxidizer or pressurant on-board. These rockets become progressively more unsafe when you: insert an igniter, load oxidizer, pressurize the pressurant tank, pressurize the oxidizer tank, ignite the igniter, and open the main propellant valve. Launch preparations of inserting the igniter are accomplished by key launch team members with observers clear of the launch pad. All the remaining operations are performed with all personnel clear of the launch pad and in bunkers.  Hazardous operations like loading the oxidizer, pressurizing pressurant tanks, pressurizing the oxidizer tank, igniting the igniter, and opening the main propellant valve can all be done by remote commands. DANGER, this type of rocket may also be susceptible to a BLEVE, depending on the type of oxidizer and tanks you use. (See the BLEVE Danger page.)

Commercial Solid Rockets
Commercial solid rockets are safely transported with no motor installed and the motor in its shipping package.  This type of rocket becomes more unsafe when you remove the rocket motor from its packaging, assemble the rocket motor, put the rocket motor in the rocket, put an igniter in the rocket motor, and ignite the motor. Assembling the motor and inserting the motor into the rocket can be performed off the launch rail. Once the rocket is placed on the launch rail an igniter is inserted into the motor by key launch team personnel.  The remaining hazardous operation is performed with all personnel clear of the launch pad and in bunkers.  The remaining hazardous operation of igniting the igniter is done by remote command.

Most motor manufacturers like to treat solid propellants as 1.3C low-explosives. FAR Site has an explosives permit. You can order and pay for a commercial solid motor and send it to FAR Site.

Experimental Solid Rockets
Experimental rocket motors become unsafe after it is formulated, mixed, and processed. The rocket motor is then placed in an explosives-magazine for safe keeping. Experimental solid rockets are safely transported with no motor installed and the experimental-motor stored in the FAR explosives-magazine.  This type of rocket becomes more unsafe when you remove the rocket motor from the explosives-magazine, assemble the rocket motor, put the rocket motor in the rocket, put an igniter in the rocket motor, and ignite the motor. Assembling the motor and inserting the motor into the rocket can be performed off the launch rail. Once the rocket is placed on the launch rail an igniter is inserted into the motor by key launch team personnel.  The remaining hazardous operation is performed with all personnel clear of the launch pad and in bunkers.  The remaining hazardous operation of igniting the igniter is done by remote command.

The State of California treats experimental solid propellants as 1.3C low-explosives. FAR has an explosives manufacturing permit. You can mix the propellant on site and store the experimental solid propellant in an explosives-magazine at FAR Site.
