#0.0022# seconds, assuming that the speed of light is not accounted for since at your given distance, the speed of light won't make much of a difference.


#"Time" = "Distance"/"Speed"#


#"0.750 m"/"340 m/s" = "0.0022 s"#

At this 'safe' distance, the person will receive severe burns, hearing loss, and would be lucky to survive the spectacular fireworks show.
