TOXICITY RESEARCH OF SMOULDERING AND FLAMING PINE TIMBER TREATED WITH FIRE RETARDANT SOLUTIONS

Timber Behaviour in Fire: the role of Pyrolysis and Smouldering Combustion

A Smouldering Fire in the Eye: Vuurtje

Herein we present the spectral-domain optical coherence tomographic (SD-OCT, Heidelberg Spectralis; Heidelberg Engineering, Heidelberg, Germany) image of an 80-year-old male patient with partial posterior vitreous detachment (PVD). Tractional forces from the vitreous body pull retinal layers by means of vitreoretinal adhesions.1,2 This high-resolution SD-OCT image illustrates how traction eleva...

Fire-retardant Treatments for Wood

Effects of Fire Retardant on Water Quality1

Ammonium-based fire retardants are important in managing wildfires, but their use can adversely affect water quality. Their entry, fate, and impact were studied in five forest streams. Initial retardant concentrations in water approached levels which could damage fish, but no distressed fish were found. Concentrations decreased sharply with time after application and distance downstream, and th...

Predicting Bending Strength of Fire-Retardant-Treated Plywood From Screw- Withdrawal Tests

This report describes the development of a test method and predictive model to estimate the residual bending strength of fire-retardant-treated plywood roof sheathing from measurement of screw-withdrawal force. The preferred test methodology is described in detail. Models were developed to predict loss in mean and lower prediction bounds for plywood bending strength as a function of a screw-wit...
