Which of the following best describes how blasting operations should be managed to ensure worker safety?

Explanation:
Managing blasting operations safely hinges on applying formal controls rather than leaving safety to chance. The best approach is to follow established blasting procedures, obtain the necessary permits, establish and enforce exclusion zones, carry out a thorough risk assessment, monitor for nuisance vibrations, and maintain waiting periods before anyone re-enters the blast area. Each element supports safety: procedures ensure consistent, vetted actions; permits authorize and document the job; exclusion zones keep workers away from flyrock, debris, and blast overpressure; risk assessment identifies specific hazards such as misfires, rock fragmentation, dust, and gas accumulations; monitoring vibrations ensures ground and structure limits aren’t exceeded, protecting personnel and nearby equipment; waiting periods allow hazardous conditions to subside, giving time for any dust, fumes, and secondary hazards to dissipate and for the all-clear to be given. Relying on common sense isn’t enough because blasting is high-risk and requires documented controls; skipping permits undermines legal and safety accountability; re-entry cannot occur immediately after a blast because hazards can persist and need assessment and clearance.
