With people across the U.S. preparing to celebrate the Fourth of July, the Occupational Safety and Health Administration (OSHA) encourages workplace safety in the pyrotechnics industry. 

Earlier this month, OSHA cited a Florida-based entertainment company after four workers died and a fifth suffered critical injuries in Orlando, Florida, after a fire and explosion at a fireworks warehouse. The agency determined that an ignition source sparked a fire and explosions as a team of workers readied fireworks for a local show.

As companies prepare fireworks displays, employers must train workers properly in a language they understand, and make certain that employees take appropriate measures to safeguard volatile devices from causing serious and potentially fatal injuries.
