Which statement is true regarding electric match igniters?

Electric match igniters, commonly used in rocketry to ignite rocket motors, are designed to be reliable and safe. The statement that they are not susceptible to discharge by static electricity is accurate because electric match igniters are engineered to be robust against accidental ignition from static discharge.

In practical terms, this quality is crucial for safety during handling and setup, as rocket enthusiasts often work in environments where static electricity could be present. An igniter that is highly susceptible to static electricity poses significant risks of unintentional ignition, which could lead to dangerous situations. Thus, the design and materials used in electric match igniters help ensure that they can withstand typical static electricity without being triggered.

Understanding this characteristic of electric match igniters is essential for anyone involved in rocketry to ensure safe practices during preparation and launch. This knowledge can also inform choices when selecting igniters for specific applications.
