Internal exposure of firefighting instructors to polycyclic aromatic hydrocarbons (PAH) during live fire training
2019
Firefighting instructors in live fire training are inevitably exposed to emissions containing, carcinogenic PAH. The study investigated PAH uptake in a group of firefighting instructors during short-term exposure in live fire training by urinary biomonitoring. Six firefighting instructors (non-smokers) completed five 2 h-training sessions each in a carbonaceous-fired simulation unit using self-containing breathing apparatuses (SCBA). Complying with a minimum time interval of six days between the individual training sessions, the participants provided urine samples before and immediately after, as well as 1, 3, 6, 9, 11, and 18 h after each training session. Samples were analyzed for 10 mono…
Experience from Indoor Fire Search and Rescue Game Design for Technology Testing
2018
No matter how good the fire evacuation plan for a building is, there is a risk of immovable victims being left behind due to smoke obscuration, inhalation of poisonous gasses, or other reasons. Firefighters usually perform the search and rescue for casualties in responding to fire hazards, besides the firefighting. Among of the challenges in the search and rescue operation is how to locate victims, and to keep monitoring the fire development so that it will not accidentally harm the fire personnel. This paper presents a game designed to test a smartphone app’s feature that supports concurrent tracking of indoor victims and fire spread. 22 volunteers were assigned roles either as rescuers or…
University Hospital Fire Disaster — Lessons to Learn
1995
Reports on hospital fire disasters are only rarely published in medical journals, and then only in journals dealing with fire fighting or hospital management. Blumenhagen found only two English language articles published between 1977 and 1987, according to which 24 500 severe events were registered in the USA, equalling three events per institution per year. However, only 30–40% of these events were reported to the fire department. In the USA only 11% of all registered events caused damage amounting to more than US$ 1 000 000.
Zbigniew Jacorzyński
2017
Pułkownik Zbigniew Jacorzyński to postać wybitnie zasłużona dla polskiego pożarnictwa. Urodził się 8 sierpnia 1921 roku w Cieszynie. Był synem oficera Wojska Polskiego. W młodości udzielał się w polskim harcerstwie. W 1937 roku stanął do poboru i dostał przydział do broni pancernej, głównie z powodu fascynacji motoryzacją. W 1939 roku ukończył liceum o profilu matematyczno-fizycznym, po czym odbył obowiązkową sześciotygodniową służbę w Junackich Hufcach Pracy w Równym, na granicy Polesia i Wołynia. W dniu 17 września 1939 roku, kiedy Sowieci przekroczyli polską granicę, cały hufiec został zmobilizowany i skierowany na odsiecz Brześcia nad Bugiem, zajętego wówczas przez Niemców. Po drodze żo…
Loop seals in circulating fluidized beds – Review and parametric studies using CPFD simulation
2020
Abstract Loop seal is a robust particle recycling technique used in circulating fluidized bed (CFB) reactors. The rate and the location of the loop seal aeration exert a significant impact on the rate of particle circulation (GS). The standpipe balances the cumulative pressure drop across the rest of the CFB by adjusting its particle height or gas-particle slip velocity. Higher fraction of the loop seal aeration naturally flows down to riser. Increased pressure drop in the standpipe results in high rate of particle circulation. Computational-particle-fluid-dynamic (CPFD) code is customized for multiphase flow modelling. The inbuilt tool of “BC connectors” was incorporated to downsize a CFB …
A Bayesian Network Model for Fire Assessment and Prediction
2015
Smartphones and other wearable computers with modern sensor technologies are becoming more advanced and widespread. This paper proposes exploiting those devices to help the firefighting operation. It introduces a Bayesian network model that infers the state of the fire and predicts its future development based on smartphone sensor data gathered within the fire area. The model provides a prediction accuracy of 84.79i¾?% and an area under the curve of 0.83. This solution had also been tested in the context of a fire drill and proved to help firefighters assess the fire situation and speed up their work.
Assessment of clogging in constructed wetlands by saturated hydraulic conductivity measurements
2019
Abstract This study aims at defining a methodology to evaluate Ks reductions of gravel material constituting constructed wetland (CW) bed matrices. Several schemes and equations for the Lefranc's test were compared by using different gravel sizes and at multiple spatial scales. The falling-head test method was implemented by using two steel permeameters: one impervious (IMP) and one pervious (P) on one side. At laboratory scale, mean K values for a small size gravel (8–15 × 10−2 m) measured by the IMP and the P permeameters were equal to 19,466 m/d and 30,662 m/d, respectively. Mean Ks values for a big size gravel (10–25 × 10−2 m) measured by the IMP and the P permeameters were equal to 12,…
Zdzisław Filingier
2017
Pułkownik Zdzisław Filingier to postać wybitnie zasłużona dla pożarnictwa zarówno na Opolszczyźnie, jak i w całej Polsce. Pułkownik Filingier urodził się 2 stycznia 1922 roku w Warszawie. Jego rodzina mieszkała w Międzylesiu. Tam Zdzisław Filingier spędził dzieciństwo i wczesne lata młodzieńcze. W latach 1935–1939 uczęszczał do gimnazjum w Warszawie, gdzie należał do harcerstwa. W czasie pierwszych miesięcy okupacji skończył tajną podchorążówkę Armii Krajowej oraz brał udział w wielu akcjach sabotażowych. Wstąpił do oddziału 25. pułku piechoty Armii Krajowej Ziemi Piotrkowskiej, działającego na Kielecczyźnie i w Górach Świętokrzyskich. Pod pseudonimem partyzanckim „Roszak” został dowódcą pl…
