As a fire sprinkler apprentice, your job is to learn how to install, test, repair, and perform maintenance on a fire sprinkler system. In this role, you may assist experienced installers, learn to cut and fit pipes, or participate in classroom training as needed. Fire sprinkler apprentices frequently accompany teams to jobs and progress through increasingly complex tasks, learning and mastering each aspect of fire sprinkler systems before moving on to the next. Precision and accuracy are especially important in this job. Fire sprinkler systems can mean the difference between life and death, so most installers have particularly high standards for work quality. Most apprenticeships last 4-5 years, and after successfully completing them, you usually have to pass a final test before moving into a journeyman position.
