 Grenfell fire

Eyewitness accounts have verified that fire and smoke travelled freely between floors and within the singular escape route inside the building. How could this possibly happen with fire spread across the external cladding outside of the building?

While the officials and regulators are investigating and hypothesizing over the cause of the fast spread of the fire (cladding, lack of sprinklers, faulty wiring, etc.), there is evidence that within the Grenfell Tower fire doors to flats had an unprotected letter plate, and some of the letter plates were not even 'fire rated'.

This is a feature in the fire door that could undermine the compartmentation of flats and fire protection of the common escape route. Now the year after the Grenfell fire there is a growing concern regarding the recent discovery by the Metropolitan Police of the failed fire doors that were installed at Grenfell and in many other similar residential buildings. It is scandalous that people who are responsible for the fire safety treat the problem with the safety of the fire doors as recently discovered.

One does not need to wait for the results of the Grenfell fire investigation to understand that putting an unprotected letter plate on a fire entrance/exit door runs the risk of utterly catastrophic consequences. And with these doors the fire could be easily started by arson through the letter plate if someone wanted.

Why we are so tolerant of 'fire rated' letter plates that put lives at risk and destroy properties when this can be easily avoided?

This case should be a wake-up call to the very real threat of the unprotected letter plate. In the final report, Dame Judith Hackitt finds that fundamental reform is needed to improve building safety and to rebuild trust among residents of high-rise buildings. It is time to acknowledge that the risks associated with the unprotected letter box are real and can be deadly. Without protecting the letter plate can we say that this will not and cannot happen again?

Prohibiting the use of the letter plates on final exit doors would solve the problem but at the expense of compromising the traditional mail deliveries. For that reason this is not always suitable. The problem can be addressed by fitting additional protection means behind the letter plate, which would ensure that the door will be fit for purpose even when the letter plate flap is in open position and protect against the letter plate related risks.

Since security comes with a price, the degree of protection can be based on the risk assessment. Ideally, the letter plate in fire doors must be protected against spread of fire and smoke even when the flap is open, or at least, as a minimum specification, it must be protected against the letter box arson, which is the serious threat to all premises be they residential, commercial or industrial. RISCAuthority regards arson as a problem that has grown since the 1950s to the extent that over 40% of all fires in industry and commerce and over 20% in residential properties are now lit deliberately.
