The VINNOVA water mist research project : A description of the 500 m3 machinery space tests
- 2003
-
Rapport (refereegranskat)abstract
- This report describes water mist and water spray system tests inside a simulated machinery space. The tests were conducted inside a compartment measuring 8,0 m by 12,5 m with a ceiling height of 5,0 m. The corresponding volume was 500 m3. The walls and the ceiling were constructed from steel plates. The test compartment replicates an intermediate size machinery space compartment onboard a ship. Either diesel oil or heptane pool fires were used as the fire source. The fires had nominal heat release rates of 500 kW, 1 MW and 2 MW, respectively and were either fully exposed to the water spray or completely shielded by a horizontal obstruction steel plate measuring 2 m by 2 m. Three different systems were tested; (1) a water spray system flowing 500 L/min at 2 bar (this system was designed according to the SOLAS convention), (2) a low-pressure system flowing 97 L/min at 12 bar and (3) a high-pressure system flowing 60 L/min at 70 bar. In addition to the tests using these three systems, free burn tests were conducted inside the compartment. This report contains a description of the test set-up, its instrumentation, the fire test procedures and a limited presentation of the results. A more thorough analysis of the test results will be made in subsequent reports, articles and papers.

Isocyanates and amines from fires - a screening over commom materials found in buildings
- 2003

Tidskriftsartikel (refereegranskat)abstract
- Isocyanates, aminoisocyanates and amines were quantified from the combustion of 24 different materials or products typically found in buildings. Small-scale combustion experiments were conducted in the cone calorimeter, where generally well-ventilated combustion conditions are attained. Measurements were further made in two different full-scale experiments. Isocyanates and amino-compounds were sampled using an impinger-filter sampling system with a reagent solution of di-n-butylamine in toluene. Filter and impinger solution were analysed separately using LC-MS technique. Further the particulate distribution in the smoke gases was determined by impactor technique, and selected gaseous compounds quantified by FTIR. It was found in the small-scale that isocyanates were produced from the majority of the materials tested. The highest concentration was found for glass wool insulation, and further high concentrations were found for PUR products, particleboard, nitrile rubber and melamine. Lower concentrations were found for wood and cable-products. Amino-isocyanates and amines were generally found from PUR products only. The distribution of isocyanates between the particulate- and fluid phases varied for the different materials and a tendency to enrichment of particles was seen for some of the materials. Further, when comparing the potential health hazard between isocyanates and other major fire gases (based on NIOSH IDLH-values) it was found that isocyanates in several cases represented the greatest hazard.

Fire safety regulations and performance of fibre-reinforced polymer composite ship structures
- 2017

Tidskriftsartikel (refereegranskat)abstract
- This paper presents a procedure for how to relate fire performance of fibre reinforced polymer (FRP) composite structures to the fire safety regulations in SOLAS II-2. It can be used as basis when performing a fire risk assessment to demonstrate that the degree of safety is at least equivalent to that provided by prescriptive requirements. A key issue is that requirements and test methods are based on a use of steel structures, which requires seeking the safety level implied by the regulations. This was demonstrated for the regulations and introduced hazards affecting the growth stage of a fire. The safety implied by regulations was related to fire performance of FRP composite by reference to fire tests involving typical materials and some relevant safety measures. Ignition was described as uncritical whilst the fire growth on an FRP composite surface can be rapid. Flammability requirements are generally not achieved by an untreated panel but different means can be used for protection. A fire protective coating can be used to prevent ignition and sprinkler is effective both for fire prevention and extinguishment on interior and external surfaces. For interior spaces it can be relevant with a coating or thermal insulation also to hinder increased generation of smoke and toxic gases during fire evacuation. In total it is shown that fire hazards during the fire growth stage are manageable and a foundation is lain out for a well-structured fire risk assessment.

Konferensbidrag (refereegranskat)abstract
- Reduced weight makes use of fiber reinforced polymer composite desirable in maritime construction applications. Exterior ship surfaces in combustible materials are although not covered by firesafety regulations and their fire protection is therefore a key issue. This paper reports how SP FIRE 105, a standardized test method for testing reaction to fire properties of façade systems, was adjusted and used to evaluate the potential for fire growth on external combustible ship surfaces; in particular fiber reinforced polymer composite surfaces protected with active or passive measures. The trials show that the test method is highly suitable but that some adjustments could be made to reduce uncertainties; in particular to use a gas burner instead of a heptane pool fire source and to add a strong criterion for when to activate active measures. Further efforts should also be made to develop suitable performance criteria, which were suggested to be based on the produced heat and the gas temperatures at the top of the panel.
