Grenfell Tower Disaster
Flammable Refrigerants & the Grenfell Tower disaster
Flammable refrigerants used as insulation blowing agent (cladding & appliance) & coolent in the refrigerator play a major role in the Grenfell Tower disaster.
1) Grenfell Tower Disaster event which led to 72 people died unnecessarily had they & the fire authority been clearly warned that the refrigerator operates with highly flammable refrigerant , the refrigerator insulation is highly flammable (see which?) or the clading insulation is made with highly flammable blowing agent;
Started by a Hotpoint / Whirlpool refrigerator-freezer insulation foam produced using butane (A3 class highly flmmable) Blowing Agent3 and the refrigerator cooling circuit charged with A3 class1 (highly flammable) R600a Refrigerant EXPLODING and spreading the fire to the building cladding. (see Intertek report page 11-12) & (Which? report)
Fire spreading furiously through cladding foam, by Kingspan/Celotex produced useing A3 class highly flammable Blowing Agent3

The culprit materials: Flammable Refrigerantsa
- A3 classa Highly flammable R600 (Butane) refrigerant as a Blowing Agent3 used in the manufacture of Refrigerator/freezer insulation. Caught fire (see Test report page 11-12) & (Which? report)
- A3 classa Highly flammable R600a (Isobutane) used as refrigerant (known as coolent or gas) by Whirlpool/Hotpoint Refrigerator/freezer circuit. Expolded after the flammable insulation caught fire from a capacitor spark, and spread fire to clading insulation.
R600a A3 class refrigerant was introduced to domestic refrigerators & freezers in 2000 - 2004 by some manufacturers replacing A1 class non-flammable (since 1928!) (R12 or R134a ) ignoring warnings from industry & UN Fact Sheet13 which aimed at removing Ozon depleteing refrigerants (CFC & HCFC).
A3 highly flammable (Butane) refrigerant used as insulation blowing agaent use started in 2006 - 2008 to replace CFC / HCFC A1 class non-flammable refrigerants. A3 & A2 class are fire propagator while A1 class is fire supressor. Refer to BSEN 13501-1 for insulation clasification
2) Independent Review of Building Regulations & Fire Safety
as a result of the Grenfell disaster occured in June 2017.
Final Report by Dame Judith Hackitt - May 2018
"The principles of health and safety law do not just apply to those who are engaged in work but also to those who are placed at risk by work activities, including members of the public"
"Residents and consumers need to be at the heart of any new regulatory system"
"This is the very least we can all do for the bereaved and the survivors of the tragdy that occurred on 14 June 2017, and for everyone who needs to know that their homes are safe for them to live in"
“We need a culture change in this industry. You need to care about the building that you are in the supply chain for. You need to care that the people who are going to live in them, work in them and sleep in them feel safe and are safe. Until you care, this system will not change and will not work"
"Why would you want to wait? Why not get ahead of the game and your competitors?”

Space Air (since 1980) is concerned and care to our industry and end users, that the action of Daikin and Cartel forced the introduction of single component A2L class1 (flammable) R32 refrigerant in small AC & Heat Pumps, which can lead to bigger disaster than Grenfell Tower. (click to see more).
Three simple questions needs to be answered by any manufacturer who uses flammable materials or substance in euipment or building materials used in any sturcture of buildings or dewling when there are non-flammables1 available? :
a) WHY use flammable materials (including refrigerant in Air conditioning or domestic refrigerators, and as a blowing agent in foamed insulation) when there are over 90 A1 class non-flammable1 alternatives availabe?
b) WHY manufacturers like Whirlpool, Kingspan, Celotex, Arconic and Daikin (and their R32 Cartel), use A2/A2L & A3 class1 flammables when there are safer choices by using A1 class1 non-flammable refrigerants available since 1928?
c) WHY manufacturers like, Whirlpool, Kingspan, Celotex and Daikin (& their Cartel), not make it clear on their marketing materials (including sales leaflets & WEBSITES) that the products they sell, contains flammable materials? do not meet Advertising Standards Uthority (ASA) "The CAP Code - chapter 3" ?
There are over 300 types of refrigerants in THREE Safety Classifications with regards to flammability, in accordance with ISO 817:2014 (E) & ASHRAE34 International Standards. A1 class non-flammable, A2/A2L flammable & A3 Highly flammable.
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 )
Business Cartel ; Daikin Industries/ Chemical have patented (aprox180 patents) A2L flammable R32 refrigerant used in small splits air conditioning equipment and licensed the patents to Japanese (such as Mitsubishi Electric, Fugitsu, Toshiba, etc), Korean (LG & Samsung) & Chinease AC manufacturers.
In the UK and some parts of EU Daikin have disctated that these licensed manufacturers withdraw the sale of current A1 class non-flammable and should not display on marketing materials that R32 is flammable.
Daikin have also manipulate the EU qouta system (under revision due to abouse) to force higher (5 times the normal in 2017/2018) prices of A1 class using the GWP game and ignoring safety. Daikin Europe control 29 F-gas EU quota (outoff aprox 200) of over 100 tonnes CO2 equivilant.
