Toxicity smoke construction products

Study to evaluate the need to regulate within the Framework of Regulation (EU) 305/2011 on the toxicity of smoke produced by construction products in fires

European Commission, October 2017

The study aimed to evaluate the need to regulate on toxicity of smoke generated by construction products in fire within the framework of Regulation (EU) No 305/2011 (CPR) and the possible impacts of any such measures.

The terms of reference document provided by the European Commission included six ‘main research’ questions:

i. Do Member States currently have regulations on the toxicity of smoke generated in building fires?

ii. Are there adequate fire statistics in the EU or other evidence (e.g. studies, or medical records) which reliably show that victims of building fires are due to the inhalation of toxic gases from construction products? Which are the responsible toxic gases?

iii. If the victims in building fires are mainly due to the inhalation of toxic gases from construction products, which are the available options for effectively reducing the risk (e.g. to regulate on the smoke toxicity, from constructions products at EU level, to leave Member States to regulate at national level by application of the subsidiarity principle, or to support other fire engineering measures e.g. appropriate building design, installation of alarm systems, etc.)? Which are the advantages and the disadvantages of each available option?
iv. Which would be the possible legal basis for regulating at EU level on the toxicity of smoke from fires in building? Which are the advantages and the disadvantages of each available legislative option?
v. What could be the possible effects of the above measures on the reduction of fire victims?
vi. What could be the possible effects on the marketing of construction products if regulated as above?

From these main research questions, the experience of fire regulations in Europe from within the project team and the wider community of research scientists and professionals, and the EC who were consulted during the project our understanding of the key underlying points to address have been incorporated into the Table of Evidence (see below).
