Electrical Source of Ignition Evidence at the Grosvenor Inquiry. What about the Shearer? What about the Tailgate Drive? What about all other Flame Proof Enclosures?
Is that all that we are going to hear about potential electrical sources of Ignition?
What sort of farce is this?
What, unless it can be picked up and taken to SIMTARS for testing, it is not mentioned
No mention that anyone ever so much as ran a feeler gauge around the shearer and tailgate drive flameproof electrical enclosures.
How can that be especially with what we do know of Electrical HPI’s on the Longwall at Grosvenor between 2016 and July 2019?
