Blasters - also known as explosives workers or ordnance handling experts - determine what sorts of explosives, and in what quantities, are necessary in order to carry out a job. Strong mathematical skills are important in this position to perform calculations, and the work is often carried out in order to clear areas for construction, mining, and other operations.
Safety measures must be observed at all times and blasters must always notify other workers exactly when the blast will occur and ensure that the area is entirely free and clear. Blasters are tasked with setting up explosives so they detonate at a certain time, and designing for the blast may be carried out on paper or by computer in advance. Explosive material will be handled, placed in holes, prepared, and detonated by the blaster.
State licensing as a blaster may be required for this position. Before and after a blast is carried out, a safety audit must also be carried out. After the explosion, a report must be created, usually on the computer. A high school diploma is often a minimum requirement, and schooling relating to explosives engineering is generally required, as well. The ability to lift heavy items is sometimes necessary, and strong knowledge of local and federal laws and regulations is essential. This job is usually performed outdoors, so exposure to uncomfortable weather conditions may occasionally be necessary.
