This paper presents the progress in hydrogen safety research which includes some of studies carried out at HySAFER Centre of Ulster University during last two years 2016-2018. The results of four studies are presented: modeling and simulation of radiation from cryogenic underexpanded jet fires; improved fire test protocol for hydrogen storage composite vessels accounting for dependence of fire resistance rating on the burner heat release rate; validation of the pressure peaking phenomenon for unignited releases and jet fires; and modeling of hydrogen tank fuelling.

Intumescent flame-retardant binder (IFRB) offers a great advancement for the most efficient utilization of a wide variety of passive fire safety system at the recent development. This article highlights the fire-resistance and thermal properties of the IFRB using Bunsen burner and thermogravimetric analysis. The five IFRB formulations were mixed with vermiculite and perlite for the fabrication of fire-resistant timber door prototypes. Additionally, the fire rated door prototypes were compared under 2 hours fire test. The prototype (P2), with a low density of 637 kg/m3 showed the superlative fire-resistance rating performance, resulting in temperature reduction by up to 58.9 °C, as compared with that of prototype (P1). Significantly, an innovative fire rated timber door prototype with the addition of formulating intumescent binder has verified to be effective in stopping fires and maintaining its integrity by surviving a fire resistance period of 2 hours.

Fire-resistance performance experiments with static loading-fire are investigated about two carbon fiber sheet (CFS) shear strengthened reinforced concrete (RC) beams exposed to the ISO834 standard fire. Shear strengthened RC beams are wrapped with fire insulation material- thick painted fire retardant coatings. Relationship between measure points’ temperature and time are achieved. The results suggest that: the ratio of shear-span is the main factor to fire-resistance rating and failure modes of CFS shear strengthened RC beams in fire; shear-failure fire-resistance rating are increased by thickening fire insulation to shear strengthened RC beams. A computer program is developed to calculate the temperature fields of fire insulated concrete beams shear strengthened with CFS coated thick fireproof material. This program is validated comparing with experimental results. Researches can give a supplement to produce overall fire-resistance factors of CFS shear strengthened reinforced concrete beams at high temperatures.

As buildings are growing higher and larger, more composite structures have been used. However, the steel member used for composite structure tends to rapidly lose its strength at elevated temperatures. For this reason, it is required to apply a fire resistance mechanism, but it is difficult to implement because of the cost and technical limitations in the case of fire-resistant paint. In case of fireproof spray coat, scattering phenomena, poor work conditions for wet application, and construction delay are the main challenges to be addressed. In this study, a full-scale fire resistance test of non-fire resistant cladding column was conducted in accordance with KS F 2257-7. According to the test results, the specimens CC-01, CC-02, and CC-03 failed to meet the requirements for a 3-hour fire resistance rating because of the joint deformation and less cover thickness, while CC-04, CC-05, and CC-06 with increased thickness and reinforced joints satisfied the requirements for a 3-hour fire resistance rating.

Developed a technical solution that relates to the fire safety of buildings and structures. Particularly it can be used for the classification of unreinforced masonry structures of buildings on indicators their resistance to fire. This gives the possibility of reasonable use of the existing masonry structures with the actual fire-resistance rating in buildings of various categories according to their fire hazard.

Fire-resistance performance experiments with static loading-fire are investigated about one carbon fiber sheet（CFS） shear strengthened and one without CFS strengthened reinforced concrete (RC) beams exposed to the ISO834 standard fire. Shear strengthened RC beams are wrapped with fire insulation material- thick painted fire retardant coatings. Relationship between measure points temperature, displacement and time are achieved. The results suggest that: the ratio of shear-span is the main factor to fire-resistance rating and failure modes of CFS shear strengthened RC beams in fire; shear-failure fire-resistance rating are increased by thickening fire insulation to shear strengthened RC beams; mid-span deflection of shear failure is approximate one half of bending failure when shear strengthened RC beams.
