New York State Certificate of Competency (CoC) Class B Pyrotechnician License Practice Exam

The safety buffer between fireworks and bystanders is the key idea. Fifty feet provides a practical safety margin so that sparks, hot debris, or a misfire are unlikely to reach unauthorized persons or the public. This distance balances protection with practicality for many common fireworks displays. A smaller distance, such as twenty-five feet, would risk injury from normal outputs, while larger distances like seventy-five or one hundred feet are more conservative margins used for bigger or more hazardous displays. Since this question asks for the minimum safe distance, fifty feet is the best choice.
