The United States Department of Transportation (DOT) requires that vehicles transporting dangerous goods must display the appropriate DOT hazard class placard and that placards must be displayed on all sides of the transporting vehicle.
According to DOT requirements, shipment of explosives materials necessitates that appropriate compatibility group letter or the labels must be exhibited in the placards (United States, 2018). Furthermore, if by any chance more than one compatibility group placards are needed for the transportation of explosive materials only one placard should be displayed.

In this case, assuming that explosives materials such as fireworks, ammunition, flares, and air bag inflators are being shipped hazard, class 1 placards will be used. The hazard class 1 placard should display the division number of the explosive material being transported and compatibility group letter. The division number and compatibility letter will be displayed in a bright background such as orange for proper visibility. Besides, on the placard, at the top, an explosive label will be displayed.
In the event of an accident, assuming that division 1.4 explosives such as igniters are being transported, there would be minor or insensitive hazard explosion. However, it is chiefly recognized that zirconium commonly utilized as metal powder confined in ignition powder is exceptional in ignition performance, but is at great risk of unintentional ignition when being moved. Therefore, if any of the transportation vessels such as tire are on fire, the EHS and FS responders should first carry out a risk assessment (United States, 1986). They should then devise an appropriate truck fire strategies utilizing proper suppression techniques and means to put off the fire. On the other hand, if the container is on fire, they should separate and vacate at least 1/3 mile and allow the fire burn. Moreover, unmanned monitors can be used if they can be put in place safely and quickly
