14 June 2017 - Which led to the tragic death of 72 people due to manufacturers used flammable🔥 refrigerants in the manufacture of cladding insulation and in the refrigerator cooling circuits

   

The fire started by a Hotpoint / Whirlpool refrigerator-freezer insulation foam produced using butane (A3 class highly flmmable and explosive 🔥💥) Blowing Agentignited by a capacitor spark  (Intertek report p 8-12), and the refrigerator cooling circuit charged with A3 class1 (highly flammable and explosive 🔥💥) R600a refrigerant EXPLODING and spreading the fire to the building cladding4

aA3 class Flammable & Explosive Refrigerant🔥💥 
R600a A3 class refrigerant was introduced to domestic refrigerators & freezers in 2000 - 2004 by some manufacturers replacing A1 class non-flammable been around  (since 1928) (R12 or R134a ) ignoring warnings from industry &
 UN Fact Sheet13 . A3 class was introduced to domestic refrigerators and as a blowing agent in 2005 - 2015 aimed at removing Ozon depleteing refrigerants (CFC & HCFC).without realising that CFC & HCFC are NON_FLAMMABLE. There are 3 classes of flammability:

A1 class is fire SUPRESSOR - A2/A2L🔥 class is fire PROPAGATOR while A3 🔥💥class is fire PROPAGATOR & EXPLOSIVE

Refrigerant classification
There are over 300 types of refrigerants in THREE Safety Classifications with regards to flammability, in accordance with ISO 817:2014 (E) & ASHRAE34 International Standard clearly indicate that. A1 class non-flammable, A2/A2L flammable🔥 & A3 Highly flammable🔥💥.

Greenwashing
"Greenwashing is a deceptive form of marketing that claims a company's products, policies and goals are environmentally friendly and therefore do less damage to nature, with an underlying purpose to increase profits"

Blowing Agent
Blowing agent is a substance which is capable of producing a cellular structure via a foaming process in a variety of materials that undergo hardening or phase transition, such as polymers, plastics, and metals. They are typically applied when the blown material is in a liquid stage *Note: Use of class O materials is an old out of dated national product classification (see more). Must use BS EN 13501-1 (class A1 non-combustible and non-flammable or class A2🔥 non-combustible BUT, flammable). (see UNEP - Fact sheet 

  

4Building Cladding Composite cladding typically consists of panels 3–5 millimetres (0.12–0.20 in) thick made of a core material sandwiched between two aluminium faces. Grenfell Tower was clad with composite panels with a polyethylene core which contributed to the fire; these panels cost about £2 less than ones with incombustible core.

5Business Cartel ; Daikin Industries/ Chemical have patented (approx 300+ patents) A2L flammable 🔥R32 refrigerant and components used in small splits air conditioning equipment and licensed the patents to Japanese manufacturers (such as Mitsubishi Electric, Fugitsu, Toshiba, etc), Korean manufacturers (LG & Samsung) & Chinease AC manufacturers, conditional on withdrawing current R410A non-flammable in small splits (refrigerant charge less than 3kg) and not mentioning that R32 is flammable 🔥 in their promotional materials or website. This has been applied to UK & and some EU but not the rest of the world. Daikin is and international manufacturer and claim meeting international standards & safety obligations. R410A is an A1 class non-flammable refrigerant is the dominant refrigerant in the world while 🔥 R32 has been since 2015.
