OSHA 30 Hour Construction Program Practice Test

What precaution should be taken to prevent accidental discharge during blasting operations?

1. Allowing unrestricted access to all workers

2. Short-circuiting detonators in specified holes until wired

3. Using flammable materials nearby

4. Keeping blasting equipment in the main storage area

The correct answer is: Short-circuiting detonators in specified holes until wired

The appropriate precaution to prevent accidental discharge during blasting operations involves the procedure of short-circuiting detonators in specified holes until they are wired. This practice helps ensure that the detonators are not inadvertently fired due to static electricity or other electrical interference before they are properly connected and ready for use. By short-circuiting the detonators, workers limit the potential for unintentional initiation, which enhances safety during the potentially hazardous task of handling explosives. In terms of context, maintaining strict control and safety measures around blasting operations is critical due to the risks associated with explosives. Access should be restricted to trained personnel who understand the dangers and proper handling protocols. Additionally, flammable materials should be kept away from blasting sites to minimize fire risks, and blasting equipment should not be stored in areas that do not meet safety standards, such as main storage areas where unauthorized personnel may have access. Each of these measures works together to create a safer working environment during blasting operations.
