What is the main characteristic of non-electric blasting caps?

1. They require electricity to detonate

2. They are commonly used with unconventional firing devices

3. They use shock tubes for ignition

4. They can only be used in controlled environments

The correct answer is: They use shock tubes for ignition

Non-electric blasting caps are primarily characterized by their use of shock tubes for ignition. This technology employs a thin, flexible plastic tube that transmits a shock wave from an igniter to the detonator, allowing for detonation without the need for electrical current. This makes them particularly advantageous in situations where electrical detonation might pose a risk, such as in environments where stray electrical currents could accidentally trigger an explosion. While it is true that non-electric blasting caps are indeed used with unconventional firing devices, this is not their defining characteristic. They are designed to enhance safety and reliability under diverse conditions, rather than being limited to unconventional setups. Additionally, the notion that they can only be used in controlled environments does not accurately reflect their application; non-electric caps are utilized in a variety of settings, including those that are less controlled. Lastly, since non-electric caps do not require electricity to detonate, that component does not serve as a characteristic description. Thus, the use of shock tubes distinguishes non-electric blasting caps from their electric counterparts.
