The firefighter who led the initial response to the Grenfell Tower fire has told an inquiry he received no training on evacuating tall buildings with a stay-put policy.
Michael Dowden, the watch manager with North Kensington red watch, was the first incident commander on the scene when the fire began in June last year.
It is feared that the London Fire Brigade's failure to abandon stay-put advice to residents for nearly two hours could have contributed to the death toll.
Richard Millett QC, counsel to the inquiry into the blaze, took Mr Dowden through national policy guidance and asked him if he had specific training on certain points. Mr Dowden said he was not aware of the document's existence.
One included: "Incident commanders should understand when a partial or full evacuation strategy might become necessary in a residential building where a stay-put policy is normally in place."
Asked if, as an incident commander, he had received such training, Mr Dowden replied after a long pause:
Chairman Sir Martin Moore-Bick asked: "Did anyone give you any help or advice in understanding when it might be necessary to have a full evacuation, things to look out for, or was it just down to your personal experience?"
Mr Millett asked if it would be fair to say that training was "a lot about what the policy contained but you weren't trained in how to implement it", Mr Dowden replied: "I would say that is a fair comment."
Mr Millett asked the firefighter: "Mr Dowden, did you ever receive training on the evacuation of people from the upper floors of high-rise buildings who may have mobility difficulties?"
Mr Dowden responded: "Not on the practical application but more theory-based."
Mr Dowden's training record was then brought on to the screen, showing several sessions he led on tackling high-rise blazes in previous years.
He was listed as a "lecturer", but said the contents of his lessons were never checked by supervisors or superiors, only auditors who visited occasionally.
Mr Millett asked him: "How could you know that the lectures that you were giving to your firefighters about high-rise firefighting were effective?"
He replied: "I suppose the only way that I could ever really do that is to see how they apply themselves on the fireground."
The inquiry lawyer said: "Leaving it to the fireground of an actual incident? Might that not be a bit late?"
"I suppose, yes," replied the fire officer.
Many victims of the Grenfell Tower fire were elderly, some with mobility issues, who lived on the top floors of the block.
He added that practical training for tackling fire on high-rise buildings was hard because few such buildings were available to use for practice scenarios.
