New Insights into the Investigation of Smoke Production Using a Cone Calorimeter

Published paper in Fire Technology , 01.01.2019

Abstract

Smoke release data from the cone calorimeter are often underused. They may provide additional information to better understand the fire reaction of polymers and the efficiency of flame retardants. A new method is proposed to investigate the smoke release in cone calorimeter tests and to correlate it to heat release, based on studies with pure and flame retarded polymers. Smoke release rate is plotted versus heat release rate and new parameters are pointed out. In particular, parameter A represents the smoke release per unit energy (in Joules) released. Its value increases when the carbon fraction and the aromaticity of a polymer increase. It can reach around 0.05 m2/kJ for epoxy resins but is null for well-known smoke-free polyoxymethylene (POM). HRR threshold (HRRth) represents the critical heat release rate above which smoke release is measured. Its value is close to 100 kW/m2 for polyolefins but decreases drastically for aromatic polymers. The approach developed in this study is potentially useful for assessing the smoke release of different materials for a heat release rate scenario chosen arbitrarily. The influence of two specific smoke suppressants and of two specific flame retardants on smoke release is also discussed and the proposed method allows for a better understanding of their role in smoke release.

Call for evidence- UK fire safety regulatory guidance

On 18 December the British Government published a call for evidence as the first stage of a review of its fire safety regulatory guidance. Nothing is excluded. The current scope of the regulations only concerns life safety but the review invites thoughts on whether this should be extended to include property protection for certain buildings. The deadline for responses is 1 March 2019 (Source: European Fire Sprinkler Network). For more information: click here

Workshop to define a Fire Safety Mission for Europe- 3rd December 2018

Although great strides have been made in reducing the negative impacts of fire over the past few decades, the global impact of fire remains staggering. The World Health Organization (WHO) estimates global burn deaths to 180,000 annually, the vast majority of these in low and middle-income countries. Within Europe, more than 3,500 people are killed annually. In most developed countries the cost of fire damage is estimated to be at least 1% of the Gross Domestic Product (GDP). Something must be done to facilitate substantial reduction in these losses and significantly increase societal health, safety, and welfare. To better characterize the problems and develop solutions, fire safety science and engineering research needs to be integrated into societally-transformative risk mitigation and resiliency initiatives. An holistic, society-focused Fire Safety Mission is needed.

In June of this year, the European Commission published the outline for “Horizon Europe”, the research & innovation programme which will follow Horizon 2020, with a proposed budget of around 100 billion € for 2021-2028. The published text makes no mention of fire safety. The proposed structure will build on Thematic “pillars” and horizontal “missions”. The definition of a “Fire Safety Mission” is particularly suitable for the inclusion of fire safety in Horizon Europe, as fire safety is truly horizontal in nature, cutting across a broad variety of potential themes.

The International Association of Fire Safety Science (IAFSS) recently launched a position paper calling for action concerning fire research and engineering needs for the future, The IAFSS Agenda 2030 for a Fire Safe World. Using the IAFSS Agenda 2030 as a starting point for dialogue, the IAFSS and ISO TC92 would like to invite all fire safety stakeholders to a workshop to define a Fire Safety Mission for Europe.

The meeting will be hosted in the CEN/CENELEC buildings in central Brussels so space is limited. This event is for registered participants only. Registration is free, but the organizers reserve the right to charge a no-show fee for registration without participation. The tentative workshop agenda is below.

Workshop: Towards flame retardant biopolymers and biocomposites

C2MA (Centre des Matériaux des Mines d’Alès) part of IMT (Institut Mines-Télécom), Alès and EPNOE (European Polysaccharide Network of Excellence) are organizing a workshop entitled “Towards flame retardant biopolymers and biocomposites: current research strategies, scientific barriers and perspective applications”.

https://epnoefire2018.sciencesconf.org/

This workshop is a unique opportunity to gather experts in flame retardant technology and specialists in polymers and composites based on bioresources. These two communities will be brought together to enable them to work more closely. The replacement of oil-based materials by bio-based ones is one of the main trends driving the development of innovative functional materials. This leads to new challenges which need to be overcome: Which bioresources and building blocks are available to develop flame retardants from bio-based materials? Which synthesis and functionalization strategies are required? How to improve the flame retardancy of biobased materials such as, for example, natural fibres which are already used as reinforcements in composite materials?

This meeting aims to review the existing knowledge, share ideas and envisage new strategies enabling the improvement of the thermal and fire retardant behavior of biobased materials and/or to develop biobased flame retardant additives through biomimetic approaches. It is expected that the workshop will foster collaborative projects between academics and industry.

A review of fire growth and fully developed fires in railcars

First published: 17 April 2018 in Fire and Materials

A literature review was performed to assess the state of knowledge of the effects of railcar interior finish materials on fire growth and fully developed fires from railcars. An overview is provided on standards and requirements currently used to regulate interior finish materials. Following this review, an overview of experimental and computational research is provided on railcar interior finish flammability and its impact on fire growth. A survey of the research on fully developed fires and the potential heat release rates of railcars is then presented. This includes scaling laws, experimental research, and model development. Future research recommendations are then presented.
