Steel is unsafe in a hole w dynamite mainly because it

Explanation:
The danger lies in sparks. When steel is in a blast hole, it can spark if it rubs against rock or is struck by other metal or rock fragments. Those sparks in a confined borehole can ignite dynamite or the detonator, causing an unintended and potentially catastrophic detonation. Rusting or corrosion are slow, long-term issues and don’t pose the immediate threat in a blasting operation, and while steel conducts heat, the immediate ignition risk from sparks is the critical hazard here. That’s why steel in a hole with dynamite is considered unsafe.
