Though all material provisions related to safety must be in place, other matters should be in place as well. Shouldn't towers of any size run fire drills at regular intervals for the benefit of all those concerned? Grenfell caused the loss of a number of people. How far this loss could have been avoided should be the topic of a reflective discussion to take stock of the state of other towers still standing intact and see if people are safe in the event of a similar tragic occurrence.
Fire drills should be professionally led at different times of the year and different times of the day. Uncomfortable, but inevitable if anyone wants to remain alive and kicking. Fire is one of the worst nightmares one can experience. It strikes when least expected. But having the right practical training reduces silly mistakes, arms the residents with practical fire fighting skills at least in certain circumstances (such as small fires at home) and prepares the people with the right skills and mental alertness for such eventualities.
Moreover, a fire drill highlights any shortcomings in the escape process and in the people's reaction - both residents and passers-by. As the saying goes: Precaution is better than cure.
