US EPA final rule for thirty FRs

The US EPA has published new information requirements for TBBPA, TCEP, TPP and for 30 halogenated flame retardants. The new final rule under TCSA (US Toxic Substances Control Act), three FRs* (TBBPA = brominated, TCEP = chlorinated, TPP = organophosphate ester) are identified as “high priority substances” requiring submission of all published and unpublished studies to EPA.

Halogenated FRs on SVHC Candidate List

ECHA has added three brominated substances and MCCPs to the Candidate List of Substances of Very High Concern. The three brominated chemicals (BMP*, TBNPA*, DBPA*) are used in polymers resins or compounds, in foams or as intermediates. MCCPs (medium-chain chlorinated paraffins) are used as flame retardants and as plasticisers in plastics, rubbers and sealants.

NFPA report on fire in the US since 1980

Analysis of 40 years’ data concludes that the key to improving fire safety is implementation of codes and standards. In buildings where fire safety is strictly regulated, such as hospitals, schools and hotels, catastrophic fires are now rare. In apartment buildings, the rate of deaths per fire has fallen, whereas in less regulated 1-2 family homes it has increased.
