OSHA 30 Hour Construction Program Practice Test

Blasting caps must be attached to the safety fuse using which of the following tools?

1. Fuse igniter

2. Cap crimper

3. Screwdriver

4. Wrench

The correct answer is: Cap crimper

Blasting caps must be attached to the safety fuse using a cap crimper because this tool is specifically designed to ensure a secure and safe connection between the blasting cap and the fuse. The cap crimper provides the necessary pressure to properly crimp the metal parts together, which is crucial for reliable detonation. A secure connection is essential to prevent accidents and ensure that the blasting process performs as intended. Using other tools, such as a fuse igniter, screwdriver, or wrench, would not provide the level of security needed for this specific task. A fuse igniter is designed for igniting the fuse, not for attaching the caps. A screwdriver or wrench is not designed for the precision and safety required in crimping the components together. Therefore, the cap crimper is the appropriate tool that meets the safety and operational requirements established for handling blasting materials.
