8 reasons for the high number of casualties in the London fire.

The authorities' failure to heed fire safety warnings from experts led to significant loss of life in the Grenfell Tower fire in London on the morning of June 14th.

According to The Sun, the number of people currently believed to be missing after the Glenfell apartment fire in London is 65. While this is a large number, it is still fortunate compared to the authorities' estimate of 400 people whose whereabouts are unknown, based on the number of residents who normally lived in the building.

Meanwhile, the British newspaper Telegraph listed eight "failures" by authorities in the Glenfell apartment building tragedy. This also serves as a lesson in managing densely populated apartment buildings for any country.

1. The law has changed.

Prior to 1986, all buildings in the City of London had to comply with the regulations of the London Building Act, which included a provision requiring walls to be able to withstand heat for at least one hour to prevent fire from spreading between apartments or entering from the outside.

However, under Prime Minister Margaret Thatcher, the law was replaced by the National Building Regulations, and the requirement for the heat resistance time of building materials also disappeared.

2. Hazardous coating materials

Three years ago, a British fire safety expert warned authorities that tragedy could occur if they did not change regulations to ban the use of flammable insulation materials on the exterior of buildings.

In the case of the Grenfell Tower, a gap between the walls acted as a vent, fanning the flames and allowing the fire to spread to the upper floors.

3. The government doesn't care.

Following the 2009 fire at the 14-story Lakanol House in south London, which killed six people, authorities urged the government to review building and fire safety regulations. They estimated that as many as 4,000 buildings in London were at risk due to inadequate fire hazard assessments.

However, to date, that proposal has received little attention except for a few promises.

4. There is only one staircase.

Residents living in Grenfell Tower have repeatedly expressed their concerns due to the building having only one staircase leading outside. This is a common situation in buildings across England, despite warnings from experts about safety.

Those who escaped the 24-story Grenfell Tower recounted that the stairwells were not only packed with people and filled with smoke, but also lacked an automatic sprinkler system. Firefighters subsequently struggled to ascend to the upper floors.

5. There is no fire extinguishing system.

Experts say that if the Grenfell Tower had been equipped with a sprinkler system, many lives could have been saved.

6. Doors cannot prevent fire.

The London Fire Brigade has said it will investigate reports that some doors in the Grenfell Tower building are not fire-resistant. Fire-resistant doors are typically designed to help prevent the rapid spread of fire within a building in the event of a fire.

7. Inspection work

The last time Grenfell Tower was inspected for fire hazards was in December 2015. The British authorities mandate that these inspections be carried out regularly on buildings, however, the law doesn't specify how "regularly" is appropriate (!). Experts suggest that every 12 months is best.

8. Fire-retardant design

According to the UK Building Code 1991, buildings are advised to install fire containment systems between floors.

The Grenfell Tower was not equipped with this system. Moreover, given the scale of the fire, experts believe it wouldn't have been very helpful in containing the flames.

The refrigerator set Grenfell Tower on fire.

An incident with a refrigerator in an apartment caused the entire 24-story building, which was built with a flawed design, to burn down. That was a huge lesson.

Charlotte Gilard, a journalist for France Info reporting from London, confirmed that authorities are almost certain about the cause of the fire: "The fire originated in an apartment on the fourth floor. A refrigerator sparking and catching fire is almost certainly the initial cause. But what is most perplexing for investigators is why the fire spread so quickly in the 24-story building, which was renovated in 2016."

Residents who escaped the fire described smelling a very distinctive, acrid odor of burning plastic. It's a highly flammable material, and that caused the building to quickly become engulfed in flames from bottom to top.

According to the BBC, the building's exterior has a plastic coating that acts as a kind of ignition source.

Of course, so far that is only one of the lines of investigation being pursued by authorities into the cause of the fire that killed at least 17 people and injured nearly 90.

André Picot, Director of Chemistry Research at the French National Centre for Scientific Research (CNRS), put forward his hypothesis as follows: “Normally, if a plastic material is used to clad a building, people usually use PE (polyethylene), which is easy to work with and inexpensive. But it could also be PET (depolyterephthalate d'ethylene), the type of plastic commonly used for plastic bottles.”

When these plastics catch fire, the consequences are horrific because they release CO2, CO, and water vapor, which cause suffocation and lead to rapid death for those who inhale them.

According to Mr. Picot, when using plastic materials in construction, people often have to add fire-retardant components such as polybrominated resins to minimize the risk.

The risk of fire and explosions at the Grenfell Tower apartment building was not unnoticed. David Collins, who served as chairman of the Grenfell Tower residents' association until October 2016, confirmed that he had requested local authorities to investigate the building's safety.

"As many as 90% of the residents in the building signed a petition in late 2015 protesting the poor management of the building management company," Collins told the media.
