Blasters work with large machinery in a rather risky position, as they must examine the strength needed to blast surfaces such as buildings, quarries, and underground mines.
Blasters typically mark areas and drilling holes before the actual blast occurs. They then pack these holes with explosives (ranging from dynamite to black powder) to compact a charge, and connect a wire from the explosives to a plunger that will detonate when a button is pushed. This work is typically performed outdoors in various locations and requires both mental and physical strength.
Blasters must be highly knowledgeable of explosives and be able to work safely with these mechanisms to prevent any accidents or injuries on the job, and several years of experience are often required for this position. Certifications are also required in some locations, and blasters work with a range of people, from co-workers to business owners and entrepreneurs. There is some room for advancement in this position to higher salaries and even drilling positions.
