Final answer:
In California, flamethrowers that emit flames longer than 10 feet are illegal, while shorter-range devices aren't regulated by the specific flamethrower laws. However, assorted laws and regulations could still apply, making the use of any flamethrower subject to legal scrutiny.
Step-by-step explanation:
In California, flamethrowers that emit a flame longer than 10 feet are generally illegal, according to California Health and Safety Code 12750 to 12761. However, devices that discharge a flame shorter than 10 feet are not considered 'flamethrowing devices' under this code and are thus not regulated by these specific laws.
It is important for individuals to understand that even if a flamethrower falls within the legal parameters, other state or local regulations, and potential criminal laws regarding the use of such devices could apply. Using any flamethrower irresponsibly can still lead to criminal charges like arson or unlawful use of a weapon.
