When fired electrically, fireworks are connected to wirebridge fuseheads. The fuseheads can inadvertently ignite if subjected to radio hazard (RAD HAZ) when in the vicinity of radio frequency sources such as cellular (mobile) telephones or walkie-talkie radios. Further advice on this should be sought from the makers of the wirebridge fuseheads and of the communication equipment because the characteristics of all these items can vary to some extent. 

RAD HAz OR RE HAz Radio Hazard. The hazard associated with the use of electro-explosive devices (EEDs) such as wirebridge fuseheads in the vicinity of radio-frequency transmitting equipment (BS 6657 Prevention of Inadvertent Initiation of Electro-explosive Devices by Radio-frequency Radiation). 

Initiation by Radio Frequency (RF) Radiation. RF radiation, ie, radio wave radar transmitters can, under certain circumstances, initiate electroexplosive devices. This topic will be discussed under Radio Frequency Radiation, Effects on Explosives.

Primary expls (initiating) are used to start the train of reactions which results in the deton of secondary HE s or of the functioning of ammo. These expls are the most sensitive of all chemical components in military ammo, hence, the most hazardous. Primary expls can be ignited by an elec heater or spark, heat from mechanical friction, a free flame, or by an RF (radio frequency) signal. The ideal primary expl is a single compd, since this affords greatest control of its characteristics. Unfortunately, such a compd is not always available so that mixts must usually be used... 

Equipment found in laboratories that can produce hazardous amounts of electromagnetic radiation includes ultraviolet lamps, arc lamps, heat lamps, lasers, microwave and radio-frequency sources, and x-rays and electron beams.
