Which are key elements of blasting safety administration?

• A. PPE only
• B. Training only
• C. Blasting plan, permits, blast mats, access restrictions, warning signals, and an on-site supervisor
• D. Housekeeping rules

Answer: (C)

The important idea here is that blasting safety administration requires a coordinated set of administrative controls that govern how blasting is planned, approved, operated, and supervised. The right choice includes a blasting plan that outlines design, timing, and initiation methods; permits that authorize the work and ensure regulatory compliance; blast mats to contain debris and protect surrounding areas; access restrictions so only authorized personnel are exposed; warning signals to alert workers before and during blasting; and an on-site supervisor to oversee the operation and enforce the plan. Together these elements establish accountability, clear communication, and practical safeguards against flyrock, misfires, and unexpected detonation. Relying on PPE alone misses the hazard-control steps that precede a blast, training alone doesn’t enforce procedures or provide ongoing supervision, and housekeeping rules alone don’t address blasting-specific controls and oversight. This comprehensive set embodies proper blasting safety administration.
