A new national warning model for spring grass fire

A new model for grass fire warning is developed which estimates the risk of fast fire spread during spring. The model is used by SMHI, the Swedish Meteorological and Hydrological Institute, to produce hourly values of risks all over Sweden to issue warning at high-risk days. The model is also incorporated in MSB’s mobile app “Brandrisk Ute” and incorporated into their Fire Danger Maps.

Large-scale CLT compartment tests

Two large-scale cross-laminated timber (CLT) compartment experiments have recently been conducted, clearly showing the impact of exposed wood on the fire spread and fire dynamics. These tests rank as the third largest CLT compartment test in the world and give valuable knowledge to better understand the fire related risk of CLT buildings.

Water-based fire protection system concept for maritime vehicle carriers developed

Design and installation guidelines for water-based fire protection systems for closed ro-ro spaces on maritime vehicle carriers have been developed in the LASH FIRE project. The work carried out where partly based on large-scale fire tests. The system should activate automatically and keep a fire under control to allow time for the activation of the fixed-installed Carbon Dioxide system in the space.

RISE stops commercial testing of PFAS-containing foam

From February 2023 EU will ban around 200 PFAS substances. Following the precautionary principle, RISE has stopped commercial testing of all PFAS-containing firefighting foams, not only those containing the 200 on the ban list.

SAFETY CRITICAL TESTING
- with focus on batteries

A lab for safety-critical testing is under construction in Borås, Sweden. The lab is part of the SEEL initiative and is equipped to evaluate products for thermal propagation, fire exposure, vibration, cycling, and climate variation. The lab’s water- and smoke-cleaning system will be world-leading, to meet environmental and sustainability requirements.
