What documentation must be available for inspection regarding blasting?

The correct answer is that detailed records of each blast must be available for inspection. This requirement is critical because it ensures compliance with safety regulations and protocols. Detailed records typically include information such as the date and time of the blast, the quantities and types of explosives used, weather conditions, and observations of the blast effects. This documentation helps regulators, safety officers, and foremen to review past blasts to identify patterns, assess the effectiveness of blasting procedures, and ensure that operations do not pose a risk to personnel or the surrounding environment.

Having comprehensive records also supports accountability and facilitates investigations in the event of incidents or complaints. When detailed documentation is maintained, it can serve as a valuable reference for improving future blasting operations and training purposes.
