The blaze broke out at the property just before 1am.
An exercise at HMP Wormwood Scrubs was held instead, the inquiry into the fire has heard.
Commissioner of the London Fire Brigade Dany Cotton spoke at the Grenfell Tower inquiry on the choices made in battling the fire. The inquiry has asked questions about the LFB's "stay put" policy as well as issues with equipment, training and communications.
Firefighters who tackled the blaze continued their evidence.
“Not knowing what you would be sending them out to felt more of a risk to me.”
Two other people were hospitalised.
