Electrical Ex installations we do take care about, we do inspection, we do work with Ex competent personnel, we do expect to have Ex certified electrical installations in potential hazardous environment.
What about non.electrical Ex installations? What about tertiary explosion protection?
Most of training methodologies just consider both as special cases, or simply not even focusing on any at all.
On the other side: all are possible ignition sources… if not protected well enough…
We must work on it!!!
Keep up good work!
