OSHA's 'Qualified' requirement for blasters implies they must be what?

• A. Trained and competent
• B. Experienced electrician
• C. Have a medical clearance
• D. Possess a four-year college degree

Answer: (A)

The key idea here is that a blaster must be qualified, meaning they have both formal training and proven ability to perform blasting tasks safely. A qualified blaster is someone who understands the hazards of explosives, knows how to handle, store, and initiate blasting agents, can design and supervise blasting operations, and can recognize and respond to unsafe conditions. This combines specific knowledge (the right procedures and safety practices) with demonstrated competence in applying it on the job. Being trained ensures they know the correct methods and regulations, while being competent means they can apply that knowledge effectively and supervise others, making on-site decisions to maintain safety. That’s why “trained and competent” is the best description. The other options don’t fit because they describe general credentials not tied to blasting safety ability: being an electrician is a different trade, medical clearance isn’t a standard qualification for blasting duties, and a four-year college degree isn’t a requirement for being a qualified blaster. The qualification centers on training and demonstrated competency in blasting safety and procedures.
