Hello Richard, Thank you for sharing this interesting article. I remember from the Grenfell Tower fire discussion on this list, that Adam Dixon shared this UK data source for incidents:
https://www.gov.uk/government/statistical-data-sets/fire-statistics-data-tables This also includes statistics on the cause of fire: https://www.gov.uk/government/statistical-data-sets/fire-statistics-data-tables#cause-of-fire As can be seen, cooking appliances, space heating appliances, central and water heating appliances, electrical distribution, and other electrical appliances are primary causes of fire. Therefore, the use of flame-retardants, especially in appliances intended for unattended operation, is more than justified by available data. In addition, the author of the article neglects that electronic components (much more than wooden furniture) contain other potentially harmful substances (when released to the environment) that are not related to fire prevention. Typically, these are contained in larger proportion in electronics than flame-retardants. So banning flame-retardants will only partly reduce environmental risks by increasing the risk of ignition. At least for electronic components, I do not support the claim that "companies typically do not share information on which flame retardants they use": To comply with EU's RoHS Directive and REACh regulation, we have requested Full Materials Disclosures (FMD) from our suppliers and the vast majority has supplied such data. As general source of reference to identify substances typically used as flame-retardants I recommend the IEC 62474 Declarable Substance List at http://std.iec.ch/iec62474.

Well, the obvious way to determine whether flame-retardants have reduced the incidence of death or injury is to stop using flame-retardants and compare before and after. The problem, of course, is if we are wrong… This is one argument that is often used to retain ALL requirements in safety standards. However, in many cases scientific or engineering analysis can show (or not show) that a requirement contributes to the product’s safety. I’m not aware of illness or injury due to any flame-retardant in normal operation of products, although there is plenty of evidence of illness and injury from the chemicals themselves and disposal of the products.

Nevertheless, thought-provoking. Enjoy!
