MULTIPLE fire safety flaws and regulatory breaches were introduced to Grenfell Tower more than a decade ago, the inquiry into the blaze heard today.

Neither the fire lifts nor fire mains were capable of helping vulnerable residents flee the building or aiding the emergency response, expert witness Dr Barbara Lane said.

The lifts lacked an escape hatch, a secondary power supply or doors that can resist a fire for 60 minutes, as outlined in Approved Document B of the building regulations, she said.
