Principles Electrical Equipment Radio Frequency (RF) Electro-Explosive Device (EED) Ammunition functions unintentionally
Safe Separation Distances Circular ends = a right cylinder Oval (or otherwise not circular) ends = NOT a right cylinder
Safe Separation Distances • Emergency Situations: • Radius of 10m: No RF transmission • Radius of 50m: No vehicle-borne sets on transmit (eg emergency services) • Emergency instructions issued to crews of vehicles transporting EED
Calculation of Safe Separation Distances • Calculating transmitter field strength: • Type of aerial (directional or omni-directional) • Mean power supplied to antenna • The frequency or frequency band • The antenna gain • And if the transmitter has a pulse waveform: • The pulse repetition frequency (pulses per second) • The pulse width in seconds
