What type of commands must personnel performing blasting be able to give or understand?

Personnel performing blasting operations must be able to give or understand both written and verbal commands to ensure safety and effectiveness in their tasks. This dual capability is crucial for several reasons.

First, blasting operations involve complex procedures where specific information such as timing, location, and safety protocols must be communicated clearly. Verbal commands allow for immediate and direct communication, which is necessary in dynamic situations where quick decisions might be required. For instance, if a blasting supervisor needs to give a last-minute instruction or change a planned operation, verbal communication can provide the promptness needed to ensure safety.

On the other hand, written commands serve as important documentation of the procedures, safety measures, and plans associated with blasting activities. This written record is essential for compliance with regulations and for maintaining safety standards, as it provides a reference that can be reviewed and verified by all personnel involved.

Thus, proficiency in both written and verbal communication enhances overall operational safety, enabling workers to carry out their responsibilities effectively while reducing the risk of misunderstandings that could lead to accidents.
