Description, key words:

Safety measures to prevent the unintentional triggering of explosions through radio waves

Aims:

Hypothesis that radio waves cause dangerous disruption to explosive equipment (e.g. in the vicinity of transmitters). Goal: determining safety distances between electrical explosive ignition systems and transmitters dependent on transmission frequency and transmitter performance.

Activities/methods:

Determining connections and developing a mathematical programme

Results:

Standardised procedure for determining the required safety distances
